Step-by-step explanation:

(x + 3)² + 4 = 46

(x + 3)² = 42

x + 3 = ±sqrt(42)

x = ±sqrt(42) - 3

x1 = sqrt(42) - 3 = 3.480740698...

x2 = -sqrt(42) - 3 = -9.480740698...

How do i do this, my son is struggling and he needs help
expeople1 [14]

Answer:

32

Step-by-step explanation:

angle a is the outside angle. It creates a circle that will always equal 360 degrees. Since the outside angle is 302, the inside angle must be 58 degrees (360-302). The top square angle will be 90 degrees (a square angle is always 90 degrees). Since the angles in a triangle always add up to 180 degrees, we need to add 58 and 90, and then subtract it from 180, which equals 32. So, angle x equals 32.

I have to explained it in words pls help
lys-0071 [83]

Answer:

  • slope: cost per mile
  • y-intercept: fixed base cost

Step-by-step explanation:

The y-intercept is the value of y when x=0. The problem statement tells you that x is the number of miles driven, and y is the rental cost.

When the number of miles driven is zero, the rental cost is ...

  y = 2.25×0 +70

  y = 70

The cost of renting the truck is $70 when it isn't driven anywhere. The y-intercept ($70) is the basic, fixed cost of truck rental.

__

If x=1 (1 mile driven), then 2.25 is added to the cost of the truck rental. The slope (2.25) is the cost per mile driven. (That mileage cost is added to the basic rental cost.)
