Answer:

3x + 9 + 4x + x simplifies to 8x + 9

y = mx + b: m is slope, b is y-intercept

no solutions: 8x + 8

(no solution from the same slope and different y-intercept)

one solution: 4x + 1

(different slope needed)

infinitely many: 8x + 9

(same y-intercept, same slope_

Which equation shows y=−1/2x+4 is in standard form?
adelina 88 [10]

Answer:

B. x + 2y = 8 is your answer.

Step-by-step explanation:

So this is what you do:

y = -1/2x + 4 <u>You are going to add -1/2 to the other side.</u>

y + 1/2x = 4 <u>You are going to multiply the equation by 2.\</u>

B. x + 2y = 8 is your answer.

Model rocket is launched from a raised platform at a speed of 176 feet per second. Its height in feet is given by h(t)=-16t^2+17
Marat540 [252]
<span><span>The first step is to find the vertex. You do this by using the formula </span>\frac{-b}{2a}. 
<span>
Plug in b and a into the equation: </span>\frac{-176}{2(-16)}
<span>
You get </span>5.5<span>

So, it takes 5.5 seconds to get to 504 feet

A father is now two times as old as his son. Sixteen years ago he was 6 times as old
kramer

Answer:

40 years and 20 years

Step-by-step explanation:

Let the father's age be y and son's age x

Father is currently twice son's age i.e 2x

16 years ago, the son was (x-16) years old

the father was (y-16) or (2x-16) years old.........(i)

The second sentence states that the father was 6 times his sons age 16 years ago i.e 6(x-16)yrs old.............(ii)

Equating (i) to (II) gives 2x-16 = 6(x-16)

2x-16 = 6x-96

Collecting like terms, 96-16 = 6x-2x, 80 = 4x, x = 20

Therefore, son's age is 20years and fathers age is twice son's age = 40 years
