Answer:
76.8
Step-by-step explanation:
Using the proportion
→ Percent is out of 100
= 
( cross- multiply )
100n = 7680 ( divide both sides by 100 )
n = 76.8
The solution to the systems of equations is (7, 3)
Given the systems of equations expressed as:
-x + 4y = 5 ....................1
x - 5y = -2 ...................... 2
Add both equations to have:
-x+x + 4y - 5y = 5 - 2
4y-5y = -3
-y = -3
y = 3
Substitute y = 3 into equation 1:
-x + 4(3) = 5
-x + 12 = 5
-x = 5 - 12
-x = -7
x = 7
Hence the solution to the systems of equations is (7, 3)

Answer:
The y-intercept
Step-by-step explanation:
Y = mx(slope)+b(y-intercept)
mark Brainliest!!
C because it has the x variables in the numerator. This is wrong because the x axis represents horizontal movement and slope is rise over run, not run over rise
All are correct
Explanation:since in none of the answers share the same the same X value and since the graph passes the vertical line test it is a function
