saveliy_v [14]

Answer:

(X2+3)2

Step-by-step explanation:

First, you have to substitute in what f(x) equals for y since f(x) stands for y.

By doing this, the equation turns into (x2+3)2, because x2+3 is y, and 2 because the original equation way y2.

After you substitute, the answer is (x2+3)2.

2) Richard, Henry and Gavin share some sweets in the ratio 4:1:3. Richard gets 7 more sweets
sineoko [7]

Answer:

6

Step-by-step explanation:

Richard gets 7 more sweets than Gavin which would probably make Richard have the most so in total he should have around 8 whilst Gavin has 1 so right now we have 4:1:?. Basing off the fact that Richard would have the most sweets Henry would have to have 6 sweets to be able to divide half of it for 3. 4:1:3

The graph shows the numbers of quarts of yellow
allsm [11]

Answer:

Step-by-step explanation:

The given graph is a straight line graph. The y axis represents the number of quarts of yellow paint that is mixed. The x axis represents the number of quarts of red paint that is mixed. We would write the required equation in the slope intercept form. The slope intercept form equation of a straight line is expressed as

y = mx + c

Where

m represents slope

c represents y intercept.

Slope = (y2 - y1)/(x2 - x1)

Slope = (2 - 1)/(5 - 2.5) = 1/2.5

Slope = 0.4

The straight line cuts the y axis at y = 0

It means that c = 0

Therefore, the equation is

y = 0.4x
