Answer:
x=90.
Step by step explanation:
To solve the expression
, and obtaining a value for x we can do the following:
- Add 1 both sides of the equation. This will result in
⇒
. - Multiply both sides by 6, which yields
. This results in
.
Answer:

With the vertex 
We see that b = -10 and a = 2 and then the vertes wuld be:

And the best option is:
b. (-10,2)
Step-by-step explanation:
For this problem we have the following function:

And if we compare this expression with the general expression for a parabola given by:

With the vertex 
We see that b = -10 and a = 2 and then the vertes wuld be:

And the best option is:
b. (-10,2)
Answer:
Step-by-step explanation:
1 ton = 2000 pounds
.1 ton = 200 pounds
So 3 tons = 6000 pounds and .2 tons = 400 pounds
Calculated out to 6400
Answer:
angleQ+angleR is 180degrees because of the properties of isoceles trapezoid. So, if you set equation and solve, you'll get the fact that x is 12, and angleR is 130degrees, and angleQ is 50degrees. According to the properties of isoceles trapezoid, angleQ is the same as angleT. So, angleT is 50degrees
