Suppose y varies directly with x. If y = –20 when x = 2, find y when x = 14

Natasha_Volkova [10]

Answer:

y = -140

Step-by-step explanation:

Y varies directly with x

y = kx

We know y = -20 when x =2, we can solve for k

-20 = k*2

Divide each side by 2

-20/2= 2k/2

-10 =k

y = -10x

Now we want to find y when x = 14

y = -10 *14

y = -140

Answer:

see explanation

Step-by-step explanation:

Given

A = $\frac{1}{2}$ bh

a. substitute b = 6 and h = 5 into the formula

A = $\frac{1}{2}$ × 6 × 5 = $\frac{1}{2}$ × 30 = 15 units²

Multiply both sides of the formula by 2

2A = bh, that is

bh = 2A ← divide both sides by b

h = $\frac{2A}{b}$ = $\frac{2(16)}{4}$ = $\frac{32}{4}$ = 8

Using

bh = 2A ← divide both sides by h

b = $\frac{2A}{h}$ = $\frac{2(12)}{4}$ = $\frac{24}{4}$ = 6
