Answer:
(-2,-3)
Step-by-step explanation:
The first step is to find the equations of the two lines. For the first line, the slope is 3/2, while the y intercept is 0. This gives it an equation of y=3/2x. For the second line, it has a slope of -3/2, and a y intercept of -6. This gives it an equation of y=-3/2x-6. Setting these two equations equal to each other, you get
3/2x=-3/2x-6
3x=-6
x=-2
y=-3
(-2,-3) Hope this helps!
Answer:
6.45 feet
Step-by-step explanation:
He starts 17 and 1/2 feet off the ground
Elevation relative to ground: 17 1/2
Then he increases the height by 4 and 3/4
Expression: 17 1/2 +4 3/4
Elevation relative to ground: 22 1/4
Next he decreases the elevation by 15.8 feet
Expression: 22.25-15.8
Elevation relative to ground: 6.45
The answer 6.45 feet from the ground
Answer:
7
Step-by-step explanation:
Set up an equation: x ^2 -3x=28
simplify to a quadratic equation. You would then solve and get x=7
Answer:
a = 7
Step-by-step explanation:
The function given is defined at x=1 as ...
f(1) = 3·1² = 3
In order to make the limit from the left be 3, we must have ...
ax -4 = 3 . . . . for x=1
1a = 7 . . . . . . .add 4
The value of the constant "a" is 7.
