Answer:
y = 9
Step-by-step explanation:
5(y-2) = 35 (divide both sides by 5)
(y-2) = 35/5
y-2 = 7 (add 2 to both sides)
y = 7 + 2
y = 9
Answer:
Part A.
w = √(d^2 - l^2)
Part B.
w = 6ft
Step-by-step explanation:
length l = 8ft
diagonal d = 10ft
width w = ?
we can see it as a Trangle, so using a Pythagorean theorem,
d^2 = l^2 + w^2
w = √ (d^2 - l^2)
w = √ (10^2 - 8^2)
w = √ (100 - 64)
w = √ 36
w = 6
Answer:
The graph will show an initial value that is lower on the y-axis
Step-by-step explanation:
The exponential function has the next general form:
where <em>a</em> is the initial amount and <em>b</em> is the base.
If the <em>a</em> value in the function is decreased, but remains greater than 0, the y-intercept of the curve decrease.
Assuming your first equation is y = 5x+9, the equations describe lines that are coincident.
_____
Multiplying the second equation by -1, it becomes y = 5x+9, the same as the first equation.
First cross multiply to get:
80x = 65(x+3) (distribute)
80x=65x+195
15x=195 (subtract 65x from both sides)
x=13 (divide both sides by 15)
Hope this helps
