What is the answer for number 5

x = -4 and y = -6

Step-by-step explanation:

–8x + 6y = –4

2x + 2y = –20 (times 3)

Elimination

–8x + 6y = –4

6x + 6y = –60

_____________ _

-14x = 56

x = -4

–8x + 6y = –4

2x + 2y = –20 (times 4)

Elimination

–8x + 6y = –4

8x + 8y = –80

_____________ +

14y = -84

y = -6

Step-by-step explanation:

L = length

W = width

L = W + 9

A = 112 = LW = (W+9)W

So,

W2 + 9W = 112

W2 + 9W - 112 = 0

Factoring

(W-7)(W+16) = 0

W = 7, -16

We discard W = -16, since a measurement cannot be negative.

W = 7

And since L = W + 9, then L = 7 + 9 = 16

This is a 16x7 rectangle

Answer:

y=-2/5x-1

Step-by-step explanation:

I started by looking for the y-intercept of the line, where the line intersects with the y-axis and saw it was -1.

Then I looked at the slope of the line and used the rise/run strategy. From the y-intercept to the point it was 2 units down and 5 units across (2/5) and since it is going down it's negative

Plugging it in: y=mx+b

m=slope

b=y-intercept

y=-2/5x-1

graph:

The statement that correctly compares the function shown on the graph with the function y=4x + 2 is 'The function shown on the graph has a smaller rate of change, but a higher starting point.'

The rate at which one quantity is changing with respect to another quantity.

For given question;

It is given a function y = 4x + 2

This function represents a line.

We have slope of the line = 4 and y - intercept = 2

We already know that the rate of change of line is given by its slope.

So, the rate of change of given function ;

y = 4x + 2 is 4.

The starting point of function f(x) is 2.

The graph of the line passing through points (-1, 1) and (0, 4)

So using slope formula,

m = (4-1)/ 0-(-1)

m = 3

So, the rate of change of function is 3.

The rate of change of function shown on the graph is smaller than the rate of change of function y = 4x + 2

Thus, the statement that correctly compares the function shown on the graph with the function y=4x + 2 is 'The function shown on the graph has a smaller rate of change, but a higher starting point.'

Hence, The correct answer is option (A)

Answer:

There are 8 flowers.

Step-by-step explanation:

You have the 3 you filled in correct. Since there are 12 flowers, and we know that there are only two colors, once we know one color we can figure the other one out. We are told that there are 4 pink flowers. Since we know there are 4 pink flowers, we can do subtraction to find how many red flowers there are. 12-8=4. You begin with 12, then count back 4. 11, 10, 9, and then 8. This is how you find the answer. I hope this helps!

Answer:

f(8f + 7)

Step-by-step explanation:

8f^2 + 7f

= f(8f + 7)

The factor of 8f² + 7f is f(8f + 7).

Factorization in mathematics is the process of dividing a large number into smaller ones that, when multiplied together, give you the original number. Factorization is the process of dividing a number into its components or divisors.

Given:

An expression,

8f² + 7f.

To find the factor:

8f² + 7f,

= f(8f + 7)

Therefore, f(8f + 7) is the factor.

Answer:

39 cm

Step-by-step explanation:

The perimeter of a rectangle is given as 2 (w + l) or 2w + 2l, where w and l are the sides.

Let us use w as 3 cm.

The perimeter of the rectangle is 2(3) + 2l = 6 + 2l

6 + 2l = 84 cm

We move the 6 to the left hand side and it goes from positive to negative.

2l = 84 - 6cm

2l = 78 cm

Divide both sides by 2.

l = 39 cm

There you have the answer for side l.

Hope this helps.
