Step-by-step explanation:

Answer:

x= 3, y= -2

Step-by-step explanation:

5x+3y= 9

x= 25÷7 + 2÷7 y

5(25÷7 +2÷7 y)

5( 25÷7 +2÷7 y ) + 3y= 9

y= -2

x= 25÷7 + 2÷7 x (-2)

x= 3

Answer:

There were 600 eggs in total.

Step-by-step explanation:

In order to find the total amount of eggs we need to divide the percent by the eggs cracked.

First we need to convert 12% to a decimal, 0.12.

Now we need to divide the cracked eggs by the percent.

So:

72 ÷ 0.12 = 600

Answer:

0.407 because in the others 7 comes before the 0

Answer:

3 whole pizzas required.

Step-by-step explanation:

Given that:

Total number of friends invited by Bob = 11

Total number of people on the birthday party = 11 friends + 1 Bob himself = 12

Each friend has eaten = 2 pieces of pizza

Number of slices in one whole pizza = 8

To find:

Number of whole pizzas required at the birthday party.

Solution:

First of all, let us find the number of slices required for the birthday party.

Number of slices of pizza required for the birthday party = Number of slices eaten by each person multiplied by number of persons at party.

Number of slices of pizza required for the birthday party = 12 [tex]\times[/tex] 2 = 24

Now, let us divide the total number of slices with the number of slices in one whole pizza to find the total number of whole pizzas required for the party.

Number of whole pizzas required:

[tex]\dfrac{24}{8} = \bold{3}[/tex]

Answer:

(f - g)(x) = 4x² + 4x + 5

General Formulas and Concepts:

Pre-Algebra

Algebra I

Step-by-step explanation:

Step 1: Define

f(x) = 5x² - 3

g(x) = x² - 4x - 8

(f - g)(x) is f(x) - g(x)

Step 2: Find (f - g)(x)

Answer:

d. J

Step-by-step explanation:

Real numbers are the vast set of numbers that broadly categorize into Rational and Irrationals (and also the Transcendentals, which are irrational too). Every rational number and every irrational number are characteristicly different from each other. Following this order, all rationals and irrationals are real numbers. This order is best represented in the Figure J.

Answer:

J

Step-by-step explanation:

Real numbers are classified into two types,

(i) Rational numbers - A number which can be expressed as fraction, ratio or percentage is called as rational number

(ii)Irrational numbers - A number which is not rational, (i.e) cannot be expressed as a ratio or percentage is called as irrational number.

Since there are no common numbers in rational and irrational, they cannot be expressed as "G" option.

Real numbers are formed by the union of rational and irrational numbers.

Answer:

b = 6

Step-by-step explanation:

this is because you have to multiply by 3 on both sides then add 9 on both sides. then you get 6

Answer:

Step-by-step explanation:

Answer:

x < 6

Step-by-step explanation:

Distribute the 2 to the parentheses:

2(x − 3) < 6

2x - 6 < 6

Solve for x:

2x < 12

x < 6

So, x < 6 is the answer.

Answer:

f(4) is 9

f(-5) is -9

f(0) is 1

f(1/2) is 2

Answer:

x = -1

Step-by-step explanation:

-2+3x=-(x+6) distrbute the negative

-2+3x=-x-6 combine liked terms (added x & 2 to each side)

+2 +x   +x  +2

4x = -4 isolate x (divide 4 from each side)

x = -1

Answer:

X=-1

Step-by-step explanation:

First, add 2 on both sides to eliminate -2 and to get 3x alone. Now you have the product of 3x=-x-4. Next, add x on both sides to isolate negative 4. Once, you have done this you get 4x=-4. Now you divide by 4 to get x alone. And you get the product x= -1.

Answer:

16

Step-by-step explanation:

Given

u = x₁i + y₁j and v = x₂i + y₂j , then

u • v = x₁x₂ + y₁y₂

Given

u = - 4i + 8j and v = - 2i + j , then

u • v = ( - 4 × - 2) + (8 × 1) = 8 + 8 = 16

Answer:26.4 feet per second

Step-by-step explanation:

Answer:

26.4 fps (feet per second)

Step-by-step explanation:

Given:

The scatter plot and trend line.

To find:

Type of association, slope, equation of trend line and average cost of apple per pound.

Solution:

Form the given graph it is clear that the trend line passes through the two points (0,0) and (12,24).

Slope of trend line is

[tex]m=\dfrac{24-0}{12-0}[/tex]

[tex]m=\dfrac{24}{12}[/tex]

[tex]m=2[/tex]

Slope of trend line is positive. It means, it represents positive correlation.

So, the type of association of the scatter plot is positive association.

Therefore, the slope of trend line is 2.

The trend line passes through (0,0) have slope 2, so the equation of the trend line is

[tex]y-y_1=m(x-x_1)[/tex]

[tex]y-0=2(x-0)[/tex]

[tex]y=2x[/tex]

Therefore, the equation of trend line is [tex]y=2x[/tex].

Slope of the line is 2.

Therefore, the average cost of apples per pound is $2.

Answer:

  26.6°

Step-by-step explanation:

The tangent of the elevation angle is the ratio of rise to run:

  tan(angle) = 150 ft/(300 ft) = 1/2

Then the angle is the arctangent of this value:

  angle = arctan(1/2) ≈ 26.6°
