What is the y-intercept of the line whose equation is y = x - 3?
-3
1/2
3
Answer:
-3
Step-by-step explanation:
y=0-3
y=-3
By definition, the correct answer is the first option: the y-intercept is -3.
A linear equation o line can be expressed in the form y = mx + b.
where
x and y are coordinates of a point. m is the slope. b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.The ordinate to the origin is the value where the line intersects the axis. Thus, the value of x must be 0 for this to occur.
In this case you know that the form of the linear equation is y=x-3.
Being x=0, then:
y=0-3
y= -3
Finally, the correct answer is the first option: the y-intercept is -3.

Barney earns $24.75 in 3 hours if the amount that Barney earns varies directly with the number of hours, how much would he earn in 20 hours.
Answer:
$165
Step-by-step explanation:
Divide 24.75 by 3 to get how much Barney(lol) would get in a hour then I got 8.25 so 8.25 x 20 hours = $165
Answer:
165$ in 20 hours
Step-by-step explanation:
Barney earns 24.75 in 3 hours, so 24.75 / 3 is 8.25. This is every hour so you would take 8.25 and multiply it by 20. That gives you 165

find the standard matrix of the given linear transformation from r2 to r2 that performs a vertical shear that maps e1 to e1 3e2 with no change in e2 and then reflects the result through x2 axis
Answer:
[1 -3, 0 -1]
Step-by-step explanation:
Let's have two matrices A and B, such that matrix A is a complete matrix on its own, and matrix B is a complete matrix on its own too. Then, we find out that The matrices for this particular operation is
A = [1 0, 0 -1]
B = [1 3, 0 -1]
To be the standard matrix we are looking for, then we multiply matrix A by matrix B, such that
A x B = T
And then, the matrix T is
T = [1 -3, 0 -1]
in the figure below, m || n. drag and drop each label into its corresponding box to show the appropriate angle pair
Answer/Step-by-step explanation:
A. <1 and <4 => vertical angles.
They share the same vertex/corner and are opposite each other as two straight lines intersect.
B. <3 and <5 => same-side interior angles.
They lie on the same side of the transversal and within the two parallel lines the transversal intercepts.
C. <4 and <5 => Alternate Interior Angles.
These angles lie on either side of the transversal, and within the parallel blinds cut across by the transversal.
D. <3 and <7 => Corresponding Angles.
They are found in the same side of the transversal occupying the same position.

Question 1. We would like to test the null hypothesis that the treatment (HRT) has no effect on the outcome (CHD), against the alternative hypothesis that the treatment does have an effect. What would be a good test statistic
Answer:
Pearson's r test or Pearson's t- test
Step-by-step explanation:
The null hypothesis is that there is no effect on the outcome against the claim that there is some effect. The Greek letter rho is used to denote the parameter.This test can also be two tailed or one tailed depending on the direction of the parameter.
This test is used for qualitative variables.
H0: ρ= 0 against Ha : ρ≠0
It is possible to use Pearson's r test to find the t- test and do the calculations.

Two cars traveled equal distances in different amounts of time. Car A traveled the distance in 2 h, and Car B traveled the distance in 1.5 h. Car B traveled 15 mph faster than Car A.
How fast did Car B travel?
(The formula R⋅T=D , where R is the rate of speed, T is the time, and D is the distance can be used.)
Enter your answer for the box.
Answer:
Car B traveled half an hour traveled 20 miles in 1.5 h
Step-by-step explanation: If car B traveled 15 mph than add 5 to 15 (.5) and you get 20 miles in 1.5 h.

The equation for the given scenario is y=4x. Therefore, option D is the correct answer.
What is the equation of a line?The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.
Given that, (1, 4), (2, 8), (3, 12), (4, 16) and (5, 20).
Now, slope = (8-4)/(2-1)
m=4
Substitute m=4 and (x, y)=(1, 4) in y=mx+c, we get
4=4(1)+c
c=0
Substitute m=4 and c=0 in y=mx+c, we get
y=4x
Therefore, option D is the correct answer.

Step-by-step explanation:
A line passes through the point (-8,4) and has a slope of -3/2 .
Write an equation in point-slope form for this line.
Answer:
y - 4 = [tex]-\frac{3}{2}(x+8)[/tex]
Step-by-step explanation:
Point slope equation of a line passing through (x', y') and slope 'm' is given by,
y - y' = m(x - x')
We have to find the equation of the line which passes through (-8, 4) and slope [tex](-\frac{3}{2})[/tex],
By substituting these values in the equation,
y - 4 = [tex]-\frac{3}{2}(x+8)[/tex]
Therefore, point slope form for the given line is,
y - 4 = [tex]-\frac{3}{2}(x+8)[/tex]
