It is impossible to solve for both variables without a second equation.
Answer:
15
Step-by-step explanation:
BD=AC
E is the midpoint of both lines, so BE=CE
Answers:
Part A: The value of x must be 0
Part B: The value of x can be any real number
----------------------------------------------------------------
Explanation:
Part A) We have the equation (7^2)^x = 1 which simplifies to 7^(2x) = 1. The only way to get the left side equal to the right side is to have the exponent of 2x equal zero. If 2x = 0, then x = 0. So that's why x = 0 is the only solution here.
--------------
Part B) Similar to part A above, but the exponent is slightly different now. We have (7^0)^x = 1 which turns into 7^(0*x) = 1. The exponent 0*x is really 0 no matter what x is. We can plug in any real number we want for x and the left side will always be 1. This is why the solution set to this equation is the set of all real numbers.
Answer:
y=1.6x-8.4
Step-by-step explanation:
First, find the slope which is y 2 minus y 1 divided by x 2 minus x 1
Slope= 16/10 or 1.6
So now it is y=16/10x + b or y=1.6x+b
Now pick a random coordinate and substitute to find y intercept we can use the first one (29,38)
38=1.6(29)+b
y intercept = -8.4
Equation is y=1.6x - 8.4 or y=16/10x - 8.4
Hoped this helped :)
