<h3><u>The value of y is -7.</u></h3><h3><u>The value of x is 8.</u></h3>
First we need to rearrange these equations so they line up properly.
6x - 2y = 62
-x + 2y = -22
Add equations together.
5x = 40
Divide both sides by 5.
x = 8
We can plug this value in to find the value of y.
6(8) - 2y = 62
48 - 2y = 62
Subtract 48 from both sides.
-2y = 14
Divide both sides by -2.
y = -7
Answer:
No, the pool will not fit.
Step-by-step explanation:
Radius of pool: 3.14 r^2= 379.94
Divide by 3.14: r^2= 121
Square root both sides: r=11
11>10, thus the pool won't fit.
Answer:
Step-by-step explanation:
We want to find an equivalent expression for
To find an equivalent expression, we need to apply the following property of exponents:
We let a=9, n=4 and m=½x
Then :
Simplify the left hand side to get:
Therefore the correct answer is:
This can be
solve using sine law, first solve the angle created at the steeple, x
X = 180 – 40 –
32
X = 108 degrees
Solve one side,
opposite to 32 degree angle, side a
Sine law:
Sin ( 32 ) / a =
sin ( 108) / 50
Solve for a
a = 27.86 m
then
sin (40) = h /
27.86
solve for h
<span>h = 17.91 m high
is the steeple</span>
Answer:
Step-by-step explanation:
(2x^2+6x-8)(x+3)
2x^3+6x^2+6x^2+18x-8x+18
2x^3+12x^2+10x+18
