Answer:

(f-g)(4) = 10

Step-by-step explanation:

(f-g)(x) = f(x) - g(x)

= 1/2 x^2 - 1/4 x + 4 - 1/2 x + 1

= 1/2 x^2 - 1/4 x - 1/2 x + 4 + 1

= 1/2 x^2 - 3/4 x + 5

(f-g)(4)

= 1/2 (4)^2 - 3/4 (4) + 5

= 1/2 * 16 - 3 + 5

= 8 - 3 + 5

= 5 + 5

= 10

Option C is the correct values of the relationship between the number of cakes the baker makes and the number of bags of flour uses.

Solution:

Option A: Ratio of cakes baked to bags of flour used

$$\frac{9}{4}, \frac{18}{6}=\frac{3}{1} \text { and } \frac{27}{9}=\frac{3}{1}$

Here the ratios are not same.

So, this option is not true.

Option B: Ratio of cakes baked to bags of flour used

$$\frac{6}{2}=\frac{3}{1}, \frac{12}{4}=\frac{3}{1} \text { and } \frac{18}{6}=\frac{3}{1}$

Here the ratios are same.

So, this option is true.

Option C: Ratio of cakes baked to bags of flour used

$$\frac{4}{9}, \frac{6}{18}=\frac{1}{3} \text { and } \frac{9}{17}$

Here the ratios are not same.

So, this option is not true.

Option D: In this table cakes baked is 6 and the bags of flour is 18.

But a baker made 18 cakes using 6 bags of flour.

So, this option is not true.

Hence option C is the correct values of relationship between the number of cakes the baker makes and the number of bags of flour uses.

Write an equation in slope-intercept form of the line that passes through (-1,4) and (0,2)

Answer:

y = -2x + 39

Step-by-step explanation:

2 - 4 = -2 (with negative numbers graphs help a lot more)

0 - -1 (since there are two negatives together you change both of the signs to their opposite so they both become positive)

0 + 1 = 1

-2/1 = -2 because a negative divided by a positive is a negative

I found the y-intercept by substituting one of the points into y=mx+b
