Answer:
This is hard to read, but i guess that the equation is:

So we have some things to solve:
First, for any number:
x^0 = 1
then 5^0 = 1.
And for negative powers,
x^-n = (1/x)^n.
And we
Then we can rewrite our equation as:

now we can cancel the seven in the numerator and the denominator

now, remember the relation:
a^x*a^y = a^(x+y)
then:
2*2^3 = 2^4
and 2^4/2^9 = 2^-5 = (1^2)^5
Then our equation is:

15/2^5 = 0.46875
1.) 12x^2-7x-10
2.) 10x^2+31x-14
Answer:
(1,4), (2,2) (3,0)
Step-by-step explanation:
adjust the equation so that the y is isolated so subtract 4 x
2y=4x +12
Every number is divisible by 2 so you can further isolate the y
y=-2x+6
Plug your x coordinates into the equation so get the y coordinates
Okay so you would do 90 / 3 which would be feet / three=yards and then minus it. because 3 feet are in 1 yard
