Answer:

20 blocks per pound.

Step-by-step explanation:

In this question we have to determine the approximate number of blocks per pound, means we have to determine the slope of the given line in the graph.

Here end points of the line are origin (0,0) and (5,100).

Now the slope will be m = (y - y')/(x - x') = (100-0)/(5-0) = 100/5 = 20

Therefore the answer will be 20 blocks per pound.

If y=8 when x=3 when x=45

Veronika [31]

Answer:

The value of y for x = 45 is 120 .

Step-by-step explanation:

Given as :

Let The variables y and x are proportional to each others

I,e y ∝ x

Now , y = k x

So, for x = 3 , y = 8

I.e 8 = k × 3 ........1

∴ k = $\frac{8}{3}$

<u>Similarly </u>

for x = 45 , y = k × 3

I.e y = k × 45 ..........2

Now, putting the value of k in eq 2

So, y = $\frac{8}{3}$ × 45

I.e y = $\frac{8\times 45}{3}$

Or, y = 8 × 15

∴ y = 120

So, for x = 45 , y = 120

Hence The value of y for x = 45 is 120 . Answer

Nick has $7.00. Bagels cost $0.75 each, and a small container of cream cheese cost $1.29. Write an inequality to find the number

mestny [16]

If you buy 1 container of cream and an unknown number of bagels, x will represent the number of bagels you buy.
1.29+0.75x<=7.00

I say less than or equal to because you cannot buy more than 7 dollars worth of things.

Y = –x + 4<br> x + 2y = –8

valkas [14]

X=16
y= -12

X+2( -x+4)=-8
X-2x+8=-8
-1x=-16
X=16

Y=-16+4
Y=-12
