Answer:
y = 4x + 24
Step-by-step explanation:
The slope is the number in front of the x-value.
Slope intercept form is in the form of
y = mx + b (or as how I learned it)
m is the slope, and b is the y-intercept (the number that is left on the side.)
You can rearrange this by moving the x to the right side by subtracting it from both sides.
You now have 1/8y = 3 - 1/2x
which can be rearranged to
1/8y = -1/2x + 3.
You need to change the y to 1 whole instead of 1/8, so you multiply it by 8 since 8 divided by 8 is 1.
y = -4x + 24
Answer:
25
Step-by-step explanation:
a1 = 9
a2 = a1 + 4
a2 = 9 + 4
a2 = 13
a3 = a2 + 4
a3 = 13 + 4
a3 = 17
a4 = 21
a5 = 21 + 4
a5 = 25
This can more easily be done by using this formula
L = a1 + (n - 1) * d
a1 = 9
n = 5
d = 4
L = 9 + (5 -1)*4
L = 9 + 4*4
L = 9 + 16
L = 25
They are the exact same, so no.
We know that
[area of a circle]=pi*r²
r=10 in
[area of a circle]=pi*10²-----> 100*pi in²
if 360° (full circle) has an area of------------------> 100*pi in²
45°-------------------------------> X
X=45*100*pi/360-----> x=12.5*pi in²
the answer is
the option B) 12.5*pi in²
5x + 10y = 18
x = y -6, we substitute this into first equation.
5x + 10y = 18
5*(y - 6) + 10y = 18
5y - 30 + 10y = 18
So it the last option from the top.
