Answer:

X = 11, - 1

Step-by-step explanation:

Given (x-5)^2 +6 = 42

Subtract 6 from sides

(x-5)^2 = 36

take the square root of both sides

X - 5 = +/- 6

X = 11, - 1.

Harry did not solve for X.

ms. van rock's favourite part of pizza is the crust. which size pizza should she get to get 37.68 inches of crust?
Gekata [30.6K]

Answer:

The 12'' one.

Step-by-step explanation:

The crust is at the perimeter of the pizza, and the pizza is a circle, so we just need to calculate the perimeter of the different pizza sizes, and see which one has a perimeter of 37.68 in.

First, you should remember that for a circle of radius R, the perimeter is:

P = 2*3.14*R

(notice that the measures in the image are the diameters of the pizzas, and the radius is half of the diameter)

The radius that we need to have if we want a perimeter of 37.68 in is given by:

P = 37.68 in = 2*3.14*R

   (37.68 in)/(2*3.14) = R = 6 inches.

Then we need a pizza of 6 inches (or a diameter of 2*6 inches = 12 inches)

Then the pizza that Ms. Van Rock should get is the 12 inch one.

Which description of the graph of the linear inequality y ≥ 7x – 4 is correct? The graph will be a dashed line with a y-intercep
o-na [289]

Answer:

The correct option is B

B) The graph will be a solid line with a y-intercept of negative four and a slope of seven. The graph will be shaded above the line.

Step-by-step explanation:

The given equation is

y ≥ 7x - 4

Consider only the equality sign:

y = 7x-4

or

y = 7x + (-4)

The general form of any linear equation is given by:

y = mx + c

By comparing, we can see that:

m = slope = 7

Secondly consider the equation

y ≥ 7x - 4

We know that generally for the signs "equal to and greater/smaller than", we use a solid line, and for the signs "greater/smaller than", we use a dashed line.

Hence, to graph this equation we'll use a solid line.

Thirdly, find y intercept by putting x=0

y = 7(0) - 4

y = -4

The correct option is B
