Find the slope intercept equation that passes through (-3,8) and is perpendicular to the line with the equation: x-7y=12

Mathematics

Answer:

C.  y = 7x + 29 .

Step-by-step explanation:

First find the slope of the given line:

x - 7y = 12

7y = x - 12

y = 1/7 x - 12/7

The slope = 1/7 so the slope of the line perpendicular to this line is

- 1 / -1/7 = 7.

Finding the equation of the  required line:

y - y1 = m(x - x1)

y1 = 8 , m = 7 and x1 = -3:

y - 8 = 7(x + 3)

y = 7x + 21 + 8

y = 7x + 29  answer.

Gennadij [26K]

Answer:

x = -13/5

Step-by-step explanation:

let x be the number

8x + 6 = 3x - 7

move variables to left and numbers to right

8x - 3x = - 7 -6

5x = -13

x = -13/5

SOLUTION

From the question given the following statements to prove are correct, then the last part

\Delta RSU\cong\Delta TSV

The reason is Side-side-side triangle theorem

This theorem states that all three sides of a triangle are congruent (identical) to the corresponding sides of another triangle, then the triangles themselves are also congruent.

Hence the answer is Side-side-side triangle theorem

What must be true of the side lengths in order to build a triangle with only two angles the same size?
ale4655 [162]

Answer:

A triangle with two angles of the same size is an isosceles triangle. So two of its sides are going to have the same measure and the third different. The length of the sides will depend on the height of the measure of the given angles.

Step-by-step explanation:

Isosceles triangles can be classified into an isosceles right triangle, isosceles obtuse, isosceles acute depending on the measurements of its internal angles.

Brrunno [24]

If the framed picture is shaped like a square and has a 12 square foot surface area, then the answer is yes, it will fit flush against the edge of the crate.

Given Part A:

the volume of the cube = 64 cubic feet

therefore, ∛64 = 4 feet

hence one edge measures 4 feet.

Now for Part B:

the area of the square is 12 square feet.

hence, √12 = 3.36 feet.

we can observe that 3.46<4

which indicates that the area covered by the painting is less than that of the one side of the crate, which makes it easy for the painting to fit in the crate.

Hence the painting will fit a side of crate.
