Answer:
x = -3
Step-by-step explanation:
First solve it:
Subtract the x's from both sides
2y = -3x +8
2y = -5x +2
Divide by two
y= -1.5x + 4
y = -2.5x +1
set them equal to each other:
-1.5x +4 = -2.5x +1
Add 2.5 x to both sides
1x +4 = 1
x +4 = 1
subtract 4 from both sides
x = -3
Answer:
4 inches should be turned up on both sides.
Step-by-step explanation:
In order to find this, create a situation in which we give the amount turned up on each side as x. Then give the amount that isn't turned up as 16 - 2x (since 2x is the amount turned up). Now we can find the area by multiplying the 3 measurements.
100 * x * (16 - 2x) = MAX
100 * (16x - 2x^2) = MAX
-200x^2 + 1600x = MAX
Now that we have a quadratic function, we can find the maximum value of x by using the vertex formula for x values (-b/2a).
x = -b/2a
x = -1600/2(-200)
x = -1600/-400
x = 4
Yes, because the sum of any 2 sides of the triangle is greater than the value of the third side.
Answer:
x-intercept=(-1,0) y-intercept =(0,-3)
Step-by-step explanation:
Answer:
8 percent
Step-by-step explanation:
Since the formula for interest rate is the original money, the amount of years, and the inetrest rate multiplied together, we could plug it into an equation. 6000 times 4 times the ineterest rate is equal to 1920. 6000 times 4 is 24000. 1920 divided by 24000 is equal to 0.08 or 8 percent.
