A line has a slope of −5 and contains the point (−2, 4).

viva [34]

Plug them into point-slope form.

y - y1 = m(x - x1)

Where y1 is the y-value of the point, x1 is the x-value, and 'm' is the slope.

Plug in what we know:

y - 4 = -5(x + 2)

So one of our answers is C.

Now distribute -5 into the parenthesis:

y - 4 = -5x - 10

Add 4 to both sides:

y = -5x - 6

Add 5x to both sides:

5x + y = -6

So the other answer is B.

Answer:

$4n^{2} = 4(5)^{2} = 100$

(p = 8 and r = $\frac{1}{6}$ are given for confusions. We don't need it.)

What is the length of BC?

MrRissso [65]

If Two Angles in a Triangle are Equal, Then Sides Corresponding to those Angles are also Equal

From the Figure, We can Notice that ∠C = ∠B

⇒ Length of AC = Length of AB

⇒ 2x - 24 = x - 2

⇒ x = 24 - 2

⇒ x = 22

Eleanor scores 680 on the mathematics part of the SAT. The distribution of SAT math scores in recent years has been Normal with

Katen [24]

Answer:

Elanor's standardized score is 1.19
Gerald's standardized score is 0.72
Elanor has higher score

Step-by-step explanation:

To compare Elanor's and Gerald's math scores, we need to standardize them and calculate their z-scores.

z score can be calculated using the formula

z= $\frac{X-M}{s}$ where

X is the student's score

M is the mean score of the exam

s is the standard deviation of the exam

Elanor's standardized score is:

z(e) = $\frac{680-554}{106}$ ≈ 1.19

Gerald's standardized score is:

z(g)= $\frac{27-24.7}{3.2}$ ≈ 0.72

Since z(e) > z(g), Elanor has higher score
