Answer:
x = -3
Step-by-step explanation:
y = -x + 2
7x + 4y = -1
Subsitution method: (Substitute y)
7x + 4(-x+2) = -1
Expand.
7x + (-4x + 8) = -1
One plus and one minus make one minus. Two plus makes a plus.
7x -4x + 8 = -1
Simplify.
3x + 8 = -1
Isolate 3x.
3x = -1-8
= -9
Find x.
x = -9 ÷ 3
= -3
Answer:
6 meters
Step-by-step explanation:
Area is length times width. If the width is 10 and the area is 60, then you would find 10 times ??? equals 60. Or 60 divided by 10. which is 6
Pants coated $39 and shirt cost $29
68 ÷ 2 = 34
34 - 5 = 29
34 + 5 = 39
29 + 39 = 68
Answer:
<u>alternative hypothesis test</u>
<u>Explanation:</u>
<em>Remember</em>, the alternative hypothesis test usually suggests that there is a chance of variation (difference) in the data observed.
Hence, since we are told the "real estate agent believes that the values of houses in the neighborhood she works in have<em> increased </em>(the chance of variation) from last year," and that "each difference is calculated by subtracting the market value of the previous year from the market value of the current year," we can reach the conclusion that this is an example of an alternative hypothesis test.
Answer:
y = x + 2, assuming you need it in slope-intercept form.
Step-by-step explanation:
Isolate the y-value by dividing 2 from both sides of the equation.
