Answer:
a would be slope and b would be y-intercept.
m and b are usually the ones a lot of people use. m is slope and b is y-intercept.
Answer:
Option d) x = 25
Step-by-step explanation:
we have
Solve for x
Subtract 4 both sides
squared both sides
Adds 9 both sides
<u><em>Verify </em></u>
1) For x=25
----> is true
therefore
x=25 is a solution
2) For x=-7
The radicand cannot be a negative number
therefore
x=-7 is not a solution
To evaluate the expressions, you substitute -9 for x and 3 for y into the expressions
(4y)^2 - (2x)
= (4(3))^2 - (2(-9))
= (12)^2 - (-18)
= 144 + 18
= 162
4y^2 - 2x^2
= 4(3)^2 - 2(-9)^2
= 4(9) - 2(81)
= 36 - 162 = -126
7.2352297363 rounded to the nearest millionth would be 7.235230 and all I did to get the answer was count from left to right and keep the first six numbers, and round 229 up one spot and make it 230, to get the answer.
Yes it would be one because anything with the 0 on the upper corner is 1
