Answer:
y=2/3x+5
Step-by-step explanation:
Parallel lines share the same slope so we already know the slope: 2/3.
Now we need to find the y-intercept for the equation. To do that, replace 4 with b. We have y=2/3x+b.
To find out what b is, we need to plug in the x and y values we are given into the current equation. We get 7=2/3(3)+b.
7=2+b
5=b
Now we can put all the information we have together.
y=2/3x+5
Answer: C.) 1.12 seconds
Step-by-step explanation:
Hi, to answer this question we have to substitute h=0 (when the rock hits the ground the height above it is 0) in the equation given:
h (t) = –16t2 + 20
Solving for t (time)
0= –16t2 + 20
16t2=20
t2=20/16
t=√1.25 =1.12 seconds (option C)

Answer:
Step-by-step explanation:
let base be x ft. then the height is 3x+4
Answer:
2 × 2 × 3 × 5 × 3 × 3 =540
Step-by-step explanation:
Answer:
In your equation 4x+5y=-9, you've got to but your equation in slope intercept form which is y=mx+b.
First we need to get the y by itself.
Subtract 4x from each side to get:
5y=-4x-9
Next we want to divide both sides by 5.
y=-4/5x-9/5
Your slope is m which in our case -4/5.
Then our y-intercept is b or -9/5.
Your answer would then be C. slope=-4/5 and y-intercept=-9/5.
Hope this helps ;)
