Answer:
Rectangle B is a scaled copy of rectangle A.
Enlargement scale factor = 1.25
Step-by-step explanation:
<u>Rectangle A:</u>
Length = 12 units
Width = 8 units
<u>Rectangle B:</u>
Length = 15 units
Width = 10 units
<u>Rectangle C:</u>
Length = 30 units
Width = 15 units
Rectangle B length ÷ rectangle A length = rectangle B width ÷ rectangle A width = 1.25
i.e
=
= 1.25
Hence rectangle B is a scaled copy of rectangle A and the scale factor of enlargement is 1.25
Slope-intercept form of a line:
y=mx+b
m=slope
We have this equation of a line:
y=2x+3
The slope of the line will be; m=2
Ohter line that is parallel to this line(y=2x+3) will have the same slope, therefore the slope will be: m=2
Point-slope form: we need a point (x₀,y₀) and the slope:
y-y₀=m(x-x₀).
We have thel point (-4,1) and the slope:
therefore:
y-1=2(x+4) (point-slope form)
y-1=2x+8
y=2x+8+1
y=2x+9 (slope-intercept form).
answer: the equation of the line that is parallel to this line y=2x+3 , is:
y=2x+9
There is an 85 right in front of the x, red flag that you should look around there. The wording of the question says he gets 85 points per test, a perfect definition for our expression if x is the number of tests.
Answer:
The answer is C (No. These are dependent events and you can calculate the probability of this outcome using the formula)
The answer is (D).
AAA method is used to prove two triangles are similar. Since we are given that the two triangles have the same angles, but we don't know anything about their side lengths, we can't conclude that they are congruent (they could be similar).
Therefore, Kris is incorrect.
