What is the equation of a line with a slope of -1/2 and passes through the point (6,-6)

1 answer:

3 0

Well I am going to assume you need slope-intercept form. So the equation is y=mx+b. m is slope, b is y intercept. So you just plug it in -6= -1/2(6)+b. -6=-3+b. Now you figure out for b so what does b have to be to make the equation equal. Well -3 so -6=-3+-3, or -6=-6.

y=-1/2x-3

Hope that helped

5. Solve for each inverse. a. If y = 4x - 10, solve for x.

GREYUIT [131]

Answer:

x = $\frac{y+10}{4}$

Step-by-step explanation:

Given

y = 4x - 10 ( add 10 to both sides )

y + 10 = 4x ( divide both sides by 4 )

$\frac{y+10}{4}$ = x

Step-by-step explanation:

Step 1: Define

Identify

2x - 9y = 11

x = 7

Step 2: Evaluate

Substitute in x: 2(7) - 9y = 11
Multiply: 14 - 9y = 11
[Subtraction Property of Equality] Subtract 14 on both sides: -9y = -3
[Division Property of Equality] Divide -9 on both sides: y = 1/3

michael rented a truck for one day. there was a base fee of $20.95 , and there was an additional charge of 93 cents for each mil

jonny [76]

Let x = number of miles, cost per mile = 93 cents = $0.93

Cost = 20.95 + 0.93*x

200.44 = 20.95 + 0.93x

0.93x + 20.95 = 200.44

0.93x = 200.44 - 20.95

0.93x = 179.49

x = 179.49/0.93

x = 193

He drove 193 miles.

Find the value of the expression below when x =3/4 4x² + 8x - 5

kap26 [50]

Answer:

4x² + 8x - 5

= 4(3/4)² + 8(3/4) - 5

= 4 × 9/16 + 24/4 - 5

= 36/16 + 24/4 - 5

= 9/4 + 6 - 5

= 9/4 +1

= 3.25

Step-by-step explanation:

Hope it helps!!
