Let's go:

y = ax + b

{5 = 4a + b

{15 = - 6a + b

{5 = 4a + b

{- 15 = 6a - b

10a = - 10

a = - 1

5 = 4a + b

4.(-1) + b = 5

b - 4 = 5

b = 9

- 1; 9

y = -1x + 9

I hope I helped you.

How are the variables on the graph related?

Anna007 [38]

Having a look at the graph, we will find that:
For speed: it is increasing along the x-axis
For height: it is increasing along the y-axis

This means that the function is linearly increasing.

Based on this, the correct choice would be:
D. As speed increases, height increases

A fruit seller has 3 crates of apples. Each crate has 100 apples. If he packed 6 apples in 1 box. Which of these gives the numbe

xz_007 [3.2K]

Answer:

300 divided by 6

Step-by-step explanation:

Given that;

Number of crates of apple owned by fruit seller = 3 crates

Number of apples in each crate = 100 apples

He packed 6 apples in 1 box;

Unknown:

Number of boxes needed to pack all the apples = ?

This problem is pretty straight forward;

Number boxes needed to pack all apples = $\frac{Number of crates owned by fruit seller x number of apples per crate}{Number of apples per box}$

Input the parameters and solve;

Number of boxes need to pack all apples = $\frac{100 x 3}{6}$ = $\frac{300}{6}$

So the solution is 300 divided by 6

A fence is being built around a rectangular garden. The length of the garden is 35 feet, and the total fencing used to enclose t

liraira [26]

The garden's width is 45. We know this because
$35 \times 2$
(length)
$35 \times 2 + 2x = 160 \\$
35x2 is 70 and you need to neutralize that by taking away 70 from both sides.
$160 - 70 = 90$
$2x = 90$
Now divide by 2 on both sides to neutralize the 2 times x.
$90 \div 2 = 45$
meaning that leaves us with
$x = 45$

35/7 (total $ divided by total units)= 5
1 unit = $5
Sitis units times 5
4 • 5 = $20
Sitis has $20
