Answer:

a) Negative slope

$m=-\frac{5}{8}$

Step-by-step explanation:

The graph of the given line is shown in the attachment.

We can see from the grap that, the line is sloping backwards.

Therefore the line has a negative slope.

The given points are (-1,-3) and (7,-8).

We use the formula $m=\frac{y_2-y_1}{x_2-x_1}$ to find the slope of this line.

$\implies m=\frac{-8--3}{7--1}$

$\implies m=\frac{-8+3}{7+1}$

$\implies m=-\frac{5}{8}$

We can confirm from the result of our calculation that the slope is actually negative.

Alborosie

Answer:

Bolt A will fit Nut A and Nut B

Step-by-step explanation:

We have the following statements:

Nut C fits on Bolt C.

Nut B fits on Bolt B.

Nut A fits on Bolt A.

Bolt C is larger than Bolt B.

Bolt A and Bolt B are exactly the same.

Then we can say that Bolt A will fit Nut A and Nut B...

On a coordinate plane, a parabola opens up in quadrant 1. It goes through (2, 12), has a vertex at (5, 3), and goes through (8,

ruslelena [56]

Answer:

Step-by-step explanation:

You have a vertex coordinate and 2 points. In order to write the equation for that parabola, you only need the vertex and one point. We will fill in the following work form of the parabola:

$y=a(x-h)^2+k$ , where h and k are from the vertex and x and y are from the point. Filling in:

$12=a(8-5)^2+3$ and

$12=a(3)^2+3$ and

$12=9a+3$ and

9 = 9a s0

a = 1.

Now we can write the equation, filling in a, the only unknown we had, which we now know is 1:

$y=1(x-5)^2+3$

In line 88, "sheer" most nearly means<br> A) transparent.<br> B) abrupt.<br> C) steep.<br> D) pure.

nlexa [21]

The correct option is D. "sheer" most nearly means pure.

Purity is defined as the absence of contamination, contamination in any kind, the absence of sins, or the quality of being wholesome. Pure things are ones that haven't been combined with anything else. A moral and upright nun is an illustration of purity.

A soul is viewed from a religious and philosophical perspective as the very essence of a human being. It provides us with our uniqueness and humanity. Therefore, in this context, having a pure soul refers to someone whose sense of self is untarnished or uncorrupted by all the negative events taking on in the world.
