Answer:  The x intercepts are -1 and -5  or  (-1,0)   and ( -5,0)

Step-by-step explanation:

Finding the x intercepts of  a parabola is the same as finding the roots of a parabola because the x intercept is when y or g(x) is equal to zero. So set the equation equal zero.

[tex]-x^{2} -6x -5 = 0[/tex]          First  divide each term by 0 to get the largest degree coefficient to equal 0.

x^2 + 6x +5 = 0         Now find two numbers that their product is 5 and their sum is 6.  The numbers 5 and 1 works out because the 5 times 1 is 5 and 5 plus 1 is 6.

Rewrite the whole equation as

x^2 + 1x+5x +5 = 0     Now factor the left side by grouping

x(x+1) 5(x+1) = 0         Factor out x+1

(x+1) (x+5) = 0       Now use the zero product by setting each of them equal zero.

x+ 1 = 0    or    x+5 = 0

    -1    -1               -5  -5

x = -1      or  x = -5

The equation of the line will be y = (1/3)x + ( 11 / 3 ). The correct option is B.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

Let m be the slope of the line and c is the y-intercept of the line.

The equation of the line is given as,

y = mx + c

The product of the slopes of the perpendicular lines is equal to -1.

y = 3x – 2

m = 3

Then the slope of the perpendicular line will be -1 / 3. The equation of the line will be written as below:-

y = (-1 / 3)x + c

The line is passing through the point  (–2, 3). Then calculate the value of the constant.

3 = (-1 / 3 )2 + c

c = 11 / 3

The equation of the line will be:-

y = (-1/3)x + (11/ 3)

Therefore,  the equation of the line will be y = (1/3)x + ( 11 / 3 ). The correct option is B.

The value of x is 16 and the width is 4.

Step-by-step explanation:

The area of a rectangle is the length multiplied by the width, which is [tex]9\sqrt{x}[/tex].

So, [tex]9\sqrt{x}[/tex] = 36.

We divide both sides by 9, getting [tex]\sqrt{x}[/tex] = 4.

We then square both sides, getting x = 16.

The value of x is 16, and the width is 4.

Answer:

Step-by-step explanation:

Subtracting the 2 expressions

3b² - 8 - b(b² + b - 7) ← distribute parenthesis

= 3b² - 8 - (b³  + b² - 7b) ← distribute parenthesis by - 1

= 3b² - 8 - b³ - b² + 7b ← collect like terms

= - b³ + 2b² + 7b - 8 ← substitute b = - 3 into the expression

= - (- 3)³ + 2(- 3)² + 7(- 3) - 8

= - (- 27) + 2(9) - 21 - 8

Answer:

7/51

Step-by-step explanation:

Assuming that the marbles are drawn without replacement, the probability of the first marble being drawn is 7/(7+8+3) which is 7/18.

The probability of the second marble being red is 6/17, as there are 6 red marbles left and 17 marbles in the bag.

We then multiply 7/18 and 6/17, getting 7/51.

A. Commutative Property of Multiplication

D. Commutative Property of Addition

=======================================

Explanation:

The commutative property of multiplication is the idea we can multiply two numbers in any order. The rule is x*y = y*x

An example would be 2*3 = 3*2 since both sides result in 6.

The same applies to 3*(2+c) because it can be written as (2+c)*3. Simply flip the two factors 3 and (2+c).

--------------------

A similar idea is the commutative property of addition. This rule says that we can add two numbers in any order we want.

x+y = y+x

An example would be 7+9 = 9+7 because both sums result in 16

Using this rule, we can rewrite 2+c as c+2

Therefore 3(2+c) is the same as 3(c+2)

--------------------

We can't use any associative properties because we would need to have 3 terms being either added or 3 terms being multiplied, for associative rules to apply.

For instance 1+(2+3) = (1+2)+3 is an example of the associative property of addition. An example of the associative property of multiplication would be 3(7*9) = (3*7)*9

Answer:

Step-by-step explanation:

Given three functions 3x⁴, 15x³and 21x², the greatest common factor is the greatest value that can divide through the three functions at the same time.

To get this GCF, let us divide each functions into simplest form

3x⁴ = (3 *x * x) * x * x

15x³ = 5 * (3 * x * x) * x

21x² = 7 * (3 * x * x)

It can be seen that the product in parenthesis is common to the three functions given on expanding them, hence the greatest common factor of the three functions is 3 * x * x = 3x²

Answer:

$0.75 per candy bar

Step-by-step explanation:

For this problem, we simply need to set up a system of equations to find the value of a drink, and the value of a candy bar.

Let x represent the cost of a candy bar, and y represent the cost of a drink.

60x + 110y = 265

120x + 90y = 270

Now let's use the elimination method to solve for one of the variables:

60x + 110y = 265 --> -2 ( 60x + 110y = 265 ) --> -120x + -220y = -530

-120x + -220y = -530

120x + 90y = 270

-130y = -260

y = 2

Now plug the value of y into one of the equations to find the value for x:

60x + 110y = 265

60x + 110 (2) = 265

60x + 220 = 265

60x = 45

x = 45 / 60

x = 0.75

With this, we know that the cost of a candy bar is $0.75 and the cost of drink is $2.00.

Cheers.

Answer:

X^2 +4y-2

Step-by-step explanation:

Substraction gives the difference between two points or two positions.

We were told to substraction 4x2 - 3y + 4, from (3x2 - 7y + 6)

Then we can say

(4x2 - 3y + 4) -(3x2 - 7y + 6)

If we open the bracket we have

4x2 - 3y + 4 - 3x2 + 7y - 6

Then if we collect like terms we have

4x2 - 3x2 -3y +7y +4 -6

Then we have

X^2 +4y-2

Hence the substraction between 4x2 - 3y + 4, and (3x2 - 7y + 6)

gives us X^2 +4y-2

Given

Time: 07 2(A) 5(B)

Calculating (a)

First, we need to list out the possible sample space, S of A

[tex]S = \{0,1,2,3,....,9\}[/tex]

[tex]n(S) = 10[/tex]

Probability of A being a 4 is the number of occurrence of 4 divided by the number of sample space

[tex]A = \{4\}[/tex]

[tex]n(A) = 1[/tex]

Hence;

[tex]P(A) = \frac{n(A)}{n(S)}[/tex]

[tex]P(A) = \frac{1}{10}[/tex]

Calculating (b)

First, we need to list out the possible sample space, S of B

[tex]S = \{0,1,2,3,....,9\}[/tex]

[tex]n(S) = 10[/tex]

Probability of B being a 8 is the number of occurrence of 8 divided by the number of sample space

[tex]B = \{8\}[/tex]

[tex]n(B) = 1[/tex]

Hence;

[tex]P(B) = \frac{n(B)}{n(S)}[/tex]

[tex]P(B) = \frac{1}{10}[/tex]

Calculating (c)

Using the sample space in (a)

[tex]n(S) = 10[/tex]

Probability of A being less than 6 is the number of occurrence of less than 6 divided by the number of sample space

[tex]A = \{0,1,2,3,4,5\}[/tex]

[tex]n(A) = 6[/tex]

Hence;

[tex]P(A) = \frac{n(A)}{n(S)}[/tex]

[tex]P(A) = \frac{6}{10}[/tex]

[tex]P(A) = \frac{3}{5}[/tex]

Calculating (d)

Using the sample space in (b)

[tex]n(S) = 10[/tex]

Probability of B being greater than 5 is the number of occurrence of greater than 5 divided by the number of sample space

[tex]B = \{6,7,8,9\}[/tex]

[tex]n(B) = 4[/tex]

Hence;

[tex]P(B) = \frac{n(B)}{n(S)}[/tex]

[tex]P(B) = \frac{4}{10}[/tex]

[tex]P(B) = \frac{2}{5}[/tex]

Answer: the distances can be 0.65 miles (in the opposite direction to the school) or 4.65 miles (in the same direction as the school)

Step-by-step explanation:

Ok, the data that we have is:

Total distance = 9.3 mi.

The travel is:

House to school = 4 mi.

school to library = A

library to house = B

Now, we have that:

4mi + A + B = 9.3mi.

We have three possibilities:

1) The order of locations is: house, library, school

The travel from: school to library + library to house is equivalent to a travel between the school to the house = 4mi.

Then we have A + B = 4mi

4mi + A + B = 8mi ≠ 9.3mi

Then the library can not be between the house and the school.

2) The order of locations is: house, school, library.

In this case we have that the distance between the library and the house is equal to the distance between the house and the school plus the distance between the school and the library, then:

4mi + A = B.

We can replace this in our original equation:

4mi + A + B = 9.3mi

4mi  + A + (4mi + A) = 9.3mi

8mi + 2*A = 9.3mi

2*A = 9.3mi - 8mi = 1.3mi

A = 1.3mi/2 = 0.65mi

Then the distance between the house and the library is:

The 4 miles between the house and the school, plus the 0.65 miles between the school and the library:

Distance = 4mi + 0.65mi. = 4,65mi

3) The third case is when the order of the locations is:

Library, house, school.

Then the distance between the house and the library is equal to the distance between the school and the library minus the distance between the house and the school, this is:

A - 4mi = B

Now we can replace this in our distance equation:

4mi + A + B = 9.3mi

4mi + A + (A - 4mi) = 9.3 mi

2A = 9.3mi

A = 9.3mi/2 = 4.65mi

Then the distance between the house and the library is:

B = A - 4mi = 4.65mi - A = 0.65mi

Then the distance between the house and the library is 0.65 miles in this case.
