Determine the intercepts of the line that passes through the following points. (-5,-7) (0,-5) (5,-3)

1 answer:

4 0

To find the y intercept you use this equation:

y2 - y1

Same for x intercept:

x2 - x1

Pick two points, put in the values, and solve.

(-5,-7) and (0,-5)

-5 - (-7) = 2
0 - (-5) = 5

The y intercept is (0,2)
The x intercept is (5,0)

Hope this helps! :)

In triangle JKL, m of angle J = 90, m of angle K = 30, and m of angle L = 60. Which of the following statements about triangle J

Lynna [10]

Answer:

option C. $KL=2*JL$

option D. $JK=\frac{\sqrt{3}}{2}*KL$

option F. $JK=\sqrt{3}*JL$

Step-by-step explanation:

step 1

we know that

In the right triangle JKL

$sin(30\°)=\frac{JL}{KL}$

$sin(30\°)=\frac{1}{2}$

$\frac{1}{2}=\frac{JL}{KL}$

$KL=2*JL$

step 2

$cos(30\°)=\frac{JK}{KL}$

$cos(30\°)=\frac{\sqrt{3}}{2}$

$\frac{\sqrt{3}}{2}=\frac{JK}{KL}$

$JK=\frac{\sqrt{3}}{2}*KL$

step 3

$tan(30\°)=\frac{JL}{JK}$

$tan(30\°)=\frac{1}{\sqrt{3}}$

$\frac{1}{\sqrt{3}}=\frac{JL}{JK}$

$JK=\sqrt{3}*JL$

nlexa [21]

Answer:

M(-3.5, 0.5)

Step-by-step explanation:

<u>Given points:</u>

P(-6, -1) and Q(1,2)

<u>Midpoint by using midpoint formula:</u>

x = (-6 + 1)/2 = -3.5
y = (-1 + 2)/2 = 0.5

A set of bivariate data was used to create a least-squares regression line. Which of the following is minimized by the line? The

Akimi4 [234]

Answer:

The sum of the squared residuals

Step-by-step explanation:

If you sum the residuals, you would get 0

if you sum of the absolute values of the residuals you wouldn't be doing "least-squares regression"

The influence of outliers D The slope is another metric that has nothing to do in creating the regression line

The racial girls to boys and my third hour class is 2:3 . There are 12 boys in my class how many girls are there

jonny [76]

Steps:
1. Do a proportion
2/3 times x/12
2. Do 12 times 2=24
3. Divide 24 by 3
4. Your answer is 8 girls
Or you could do it this way
Steps:
1. You could have just multiplied the 2 by a 4 to get 8.12 boys divided by 3 boys is 4. That means you multiple the two by 4 to get the girls.
