Answer:

f(-4) = -6

g(2) = -14

Step-by-step explanation:

To evaluate a function we must plug in the values of x. So for:

f(x) = 2x+2

we have:

f(-4) = 2(-4)+2

then we simplify:

f(-4) = -8+2

so f(-4) = -6

Now the same steps are taken for g(x) in which the answer would be -14.

Find VW please. the picture is below

sergejj [24]

Answer:

VW = 44

Step-by-step explanation:

the line VX is parallel to ZY and intersects the other 2 sides of the triangle then it divides those sides proportionally , that is

$\frac{ZV}{VW}$ = $\frac{YX}{XW}$ ( substitute values )

$\frac{22}{VW}$ = $\frac{18}{36}$ = $\frac{1}{2}$ ( cross- multiply )

VW = 2 × 22 = 44

B. because it can be exactly 14 shirts or less than 14 shirts depending if oyu want to use all the money

C. 20 would be a solution if you wouldnt have already spent the 80 dollars on other things, since the team did it would be too much money.

Step-by-step explanation:

300- 80 = 220

220/ 15 = 14.6 round 14.6 to 14 (because you cant buy half a shirt)

Find tan of 45 degrees

Arturiano [62]

Answer:

tan(45°) = 1

Step-by-step explanation:

We know that sin (45°) = √2/2, and cos(45°) = √2/2.

Given that tan(x) = sen(x) / cos(x), we get:

tan(45°) = (√2/2) / (√2/2) = 1

Therefore, tan(45°) = 1
