45x+30= price for electrician when x= hours
Answer:
x = 9
Step-by-step explanation:
-5(1 + 1x) = -50
-5 + -5x = -50
-5 + -5x + 5 = -5x
-50 + 5 = -45
-5x = -45
-5x / -5 = x
-45 / -5 = 9
x = 9

Answer:
61.5°
Step-by-step explanation:
The tangent relation is useful here. The angle is opposite the vertical side and adjacent to the horizontal side of the right triangle.
Tan = Opposite/Adjacent
tan(α) = 35/19
α = arctan(35/19) ≈ 61.5°
The angle made by <em>v</em> and the positive x-axis is 61.5°.
Slope intercept form is y=mx+b
m=slope
b=y intercept
slope is 4
y=4x+b
subsitute if iin (x,y) form
so x=3 and y=-2 is one solution
subsitute
-2=4 times 3+b
-2=12+b
subtract 12 from both sids
-14=b
the equation is y=4x-14
Simple Answer:
Use the x and y coordinates
Step by Step Explanation:
If you are given a table the x-axis is generally on the left/top. Now look at your coordinate plane, the horizontal line is the x and the vertical line is the y. So if you are given (-6,7), you will go to the left 6 and up 7. Hope this helps!
