Answer:
y = 2x - 13
Step-by-step explanation:
Equation of a line is y = mx + c, m is the gradient and c is the intercept
The line passes through points 4 and -5, x is 4 and y is -5
-5 = 4m + c
When two lines are perpendicular, the products of their gradients are equal to -1, m1 * m2 = -1
x + 2y = 5
2y = -x + 5
y = (-1/2 * x) + 5
therefore m = -1/2
m1 * m2 = -1
m * -1/2 = -1
-m = -2 , therefore m = 2
-5 = 4 * 2 + c
c = -5 - 8, which is -13
Therefore the equation for the line is
y = 2x - 13
Answer:
$1260
Step-by-step explanation:
70/100 × $1800 = $1260
You have to input the 5 into the x place. so it would be y=3(5) and you get the answer y=15
Can you add more information??
When given a function and asked to find the value of a number, in this case g(12), simply plug 12 into all x places in the equation:
g(12)=3(12+8)
g(12)=36+24
g(12)=60
