Answer:
x = ± 
Step-by-step explanation:
To find the zeros equate the polynomial to zero, that is
x² - 7 = 0 ( add 7 to both sides )
x² = 7 ( take the square root of both sides )
x = ±
Thus the exact solutions are
x = -
, x = 
Answer:
150-30=5x
Step-by-step explanation:
If the total is $150 and a pair of jeans is $30, then you'd subtract them. Since you have to find out how much each shirt is, you'd put 5x on the other side of the equal sign. Then solve for X.

Answer:
y = 7x - 4
Step-by-step explanation:
The slope-intercept form of a line is:
y = mx + b
where m is the slope and b is the y-intercept.
Lets get the equation 7x - y = 4 into that form.
7x - y = 4
Subtract 7x from both sides.
-y = 4 - 7x
Multiply both sides by -1.
y = 7x - 4
And now we have the equation in slope-intercept form.
I hope you find my answer and explanation to be helpful. Happy studying.
Answer:
Skewed right
Step-by-step explanation:
The data set is skewed right because the highest values are on the right side.
