Answer:

b) 2x^2 + 7x + 3

= 2x^2 + 6x + 1x + 3

= 2x(x + 3) + 1(x + 3)

= (2x + 1) (x + 3)

Answer & Step-by-step explanation:

First, we know what the formula is for y-intercept slope form.

[tex]y=mx+b[/tex]

Since, we have coordinate points and the slope, then we can use these numbers to find the y-intercept, b.

[tex]7=4(-3)+b[/tex]

[tex]7=-12+b[/tex]

[tex]19=b[/tex]

So, the equation of the line that passes through (-3, 7) with a slope of 4 is..

y = 4x + 19

Answer:

4

Step-by-step explanation:

use the Pythagoras' theorem

formula for an ABC triangle( right angled)

AB is height

BC is hypotenuse

CA is length

[tex]BC^{2}[/tex] = [tex]AB^{2}[/tex] + [tex]CA^{2}[/tex]

in your case

AB is 7

BC is 8

CA is unknown so we write x

[tex]8^{2}[/tex]=[tex]7^{2}[/tex]+[tex]x^{2}[/tex]

64=49+[tex]x^{2}[/tex]

64-49=[tex]x^{2}[/tex]

15=[tex]x^{2}[/tex]

[tex]\sqrt{15}[/tex] =x

3.87=x

Answer:

x= -1

Step-by-step explanation:

make the equation to equal to zero and then bring 2 to left side of the equal sign. To get rid of (x), you simply divide both sides by 2 and you will get x= -1.

Answer:

RC1.  5

RC2. 8

RC3. a

RC4. 3

Step-by-step explanation:

So basically what you need to start with is the fact that the second triangle is 2 times larger than the first.

so,

8 = 8

C = 10

A = 6

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

the next important part is that the opposite sides of the fraction, when multiplied are equal to each other.

( for example 1/2 = 2/4, because 1*4 = 4 and 2*2 = 4)

RC1. a/3 = C/_

substitute

6/3 = 10/_

3 * 10 = 30

6 * _ =30

30/6 = 5.

Rc2. 4c = 5_

4*10 = 5*_

40/5 = 8

RC3. 3c = 5*_

3*10 = 5*_

30/5 = 6

RC4. 4a = 8*_

4 * 6 = 8*_

24/8 = 3

good luck with your schoolwork/homework!

Answer:

Step-by-step explanation:

a)

If we implement the combinations recursively without memoization, then the running time would be exponential in n.

Time Complexity:

If we implement this equation literally, as a recursive program, then the running

time of our algorithm without using memoization, T(n), as a function of n, has the following behavior:

T(0) = 1

T(1) = 1

T(n) = T(n − 1) + T(n − 2).

But this implies that

T(n) ≥ 2T(n − 2) = 2^(n/2).

b)

But if we store the combinations in an array, C[][], then we can instead calculate the combinations, C(n,k), iteratively, as follows:

C[0,0] = 0

C[1,1] = 1

for i = 2 to n do

C[n,k] = C[n-1, i−1] + C[n-1,k]

This algorithm clearly runs in O(n) time, and it illustrates the way memoization

can lead to improved performance when subproblems overlap and we use table

lookups to avoid repeating recursive calls.

Put 3/4 - 5/16 over the common denominator 16. 3/4 - 5/16 = (4×3)/16 - 5/16:

(4×3)/16 - 5/16

4×3 = 12:

12/16 - 5/16

12/16 - 5/16 = (12 - 5)/16:

(12 - 5)/16

12 - 5 = 7:

Answer: 3/7

__________________________________________________

4. Rewrite the decimal number as a fraction with 1 in the denominator

0.984=0.984/1

Multiply to remove 3 decimal places. Here, you multiply top and bottom by 10^3 = 1000

(0.984/1)×(1000/1000)= 984/1000

Find the Greatest Common Factor (GCF) of 984 and 1000, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 8,

(984/8) = 123

(1000/8) = 125

Therefore

X=123/125

In conclusion,

Answer: 0.984=123/125

Answer:

Aloy has $55 initially

Benjamin has $95 initially

Step-by-step explanation:

In this question, given the order in which the money flowed in the question, we want to know how much each of the two had initially.

let what Aloys have be x and what Benjamin has be y.

Together, they had 150

x + y = 150 ••••••••(i)

Aloys mother gave him 40, new money is x + 40, Benjamin spent 10, new money is y-10

the new difference is 10

Thus;

(x + 40)-(y-10) = 10

x + 40 -y + 10 = 10

x+ 40 = y

substitute this into the first equation

x + 40 + x = 150

2x + 40 = 150

2x = 150-40

2x = 110

x = 110/2

x = $55

y = x + 40 = 55 + 40 = $95

D. Rhombus

Step-by-step explanation:

Rhombus is the quadrilateral that lhas 2 pairs of angle with equal measures and 4 sides of equal length

Attached picture is the shape of Rhombus

Answer: The correct answer is option D; Rhombus

Step-by-step explanation: Basically, all the four options are quadrilaterals, or a plane shape with four sides. However, not all four-sided plane shapes have the same properties, and hence each of them has its own unique name due to its unique features or properties. A rhombus has four sides that are equal in measurement, but not all its four angles are equal in measurement. Two pairs of angles are equal to each other, and these are the pair of opposite angles. Also, the opposite sides/lines are parallel and congruent to each other.

A rectangle has, two opposite sides parallel and congruent, but unlike a rhombus, not all sides measure the same length. Only two opposite sides have equal measurement. In a rectangle, all four angles are congruent and they all measure 90 degrees each.

A trapezoid has only two sides as being parallel, and the other two sides are not parallel. The two parallel sides are referred to as the bases.

A parallelogram also has two equal sides as being parallel to each other and the two opposite sides are also congruent, just like a rhombus. However, unlike a rhombus, a parallelogram does not necessarily have all sides congruent. The two opposite sides may be equal in measure just like in a rectangle, but the angles are not all equal like in a rectangle.

Therefore, only a rhombus satisfies the conditions outlined in the question namely;

Two pairs of angles with equal measures, and four sides of equal length.

Answer:

I can't post a graph, but I will explain how to do it.

Step-by-step explanation:

The y intercept is 3, so we know we can place a point at the coordinates (0,3). The y intercept is the point where your line crosses the y axis.

The slope is -3, which is the same as -3/1. The top number is the y axis, the bottom number of the slope is the x axis. This tells us that for every 1 space we move on the x axis, we move -3 spaces on the y axis. You should therefore have a second point located at (1,0).

You should end up with a line with a point at (0,3) and (1,0) which slopes down from left to right. Hope that helps.

The line of the graph is y=-3x+3

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

Slope is -3 and y-intercept is 3.

y=-3x+3

Now we have to plot the graph

x   0      1     2    3     4

y    3     0    -3   -6   -9

Hence, the line of the graph is y=-3x+3

Answer: A = {2, 6 ,6 , 6 , 7 ,9}

Step-by-step explanation:

As the mode is 3, we must have a number that repeats 3 times.

As the median is 6, the number in the middle must be 6

then with this we can construct a set with 3 times the number 6.

Now, knowing that the range is 7. the difference between the larger number and the smaller number is 7, so suppose the larger number is 9 and the smaller number is 2 (9 - 2 = 7)

Then the numbers in our set are:

2 6 6 6 9

lets find the last one.

We know that the mean is 6, then we have

6 = (1/6)*( 2 + 6 + 6 + 6 + 9 + x) = (1/6)(29 + x)

6*6 = 29 + x

36 - 29 = x

x = 7

Then our set is:

A = {2, 6 ,6 , 6 , 7 ,9}

Where the number in the middle is 6, the mean is 6, the mode is 3 and the range is 7

Answer:

When given a percentage of growth or decay, determined the growth/decay factor by adding or subtracting the percent, as a decimal, from 1. In general if r represents the growth or decay factor as a decimal then: b = 1 - r Decay Factor. b = 1 + r Growth Factor. A decay of 20% is a decay factor of 1 - 0.20 = 0.

Step-by-step explanation:

The growth factor is 1.24, and the decay factor is 0.76 for the 24% growth add one as a decimal and for decay subtract one as a decimal.

It is defined as the factor that represents the increase and decreases in value by that factor. For the growth add one as a decimal and for the decay subtract one as a decimal.

For the growth factor:

F(g) = 1+r

Here r = 24% = 0.24

F(g) = 1+0.24 = 1.24

For the decay factor:

F(d) = 1-r

Here r = 24% = 0.24

F(d) = 1-0.24 = 0.76

Thus, the growth factor is 1.24, and the decay factor is 0.76 for the 24% growth add one as a decimal and for decay subtract one as a decimal.
