Write an equation of the line that passes through the point (4, –5) with slope 2.
A. y−4=−2(x+5)
B. y+5=2(x−4)
C. y−4=2(x+5)
D. y+5=−2(x−4)
Answer:
The correct choice is option B. y + 5 = 2(x−4)
Step-by-step explanation:
slope = 2
y = mx + b
-5 = 2(4) + b
-5 = 8 + b
-8 -8
------------------
-13 = b
y = 2x - 13, in other words --> y + 5 = 2(x−4)
So, y + 5 = 2(x − 4) is the equation of the line that passes through (4, -5).

In the year 2015 Emily was three times as old asKaitlin. By the year 2021 Kaitlin will be half asold as Emily will be. How old was Emily on theyear 2000?
In 2000 Emily was 9 years old.
Given that in the year 2015 Emily was three times as old as Kaitlin while by the year 2021 Kaitlin will be half as old as Emily will be, to determine how old was Emily on the year 2000 the following calculation must be performed:
2015 = E = 3K 2021 = E = 2K 24 /// 8 --- 30 /// 14 18 /// 6 --- 24 /// 12 18/6 = 3 24/12 = 2 2015 = Emily was 24 years old 24 - (2015 - 2000) = X 24 - 15 = X 9 = X
Therefore, in 2000 Emily was 9 years old.

These are supplementary angles. So they measure to 180º. 180º-95º=85º. 85º-10= 84º. 84º÷12x= 7.
Answer:
12x+1°+95°=180° (int angles)
12x+96°=180°
12x=180°-96°
=84°
x=84÷12

12a + 5 - 8a = -1
m - 3 - 6m = -27
please solve
c = -6
a = -3/2
m = -24/5
Step-by-step explanation:
#15(c + 2) = -20
5c + 10 = -20
5c = -20 - 10
5c = -30
c = -6
#212a + 5 - 8a = -1
4a + 5 = -1
4a = -1 - 5
4a = -6
a = (-6)/4
a = -3/2
#3m - 3 - 6m = -27
-5m - 3 = -27 → (times -1)
5m + 3 = 27
5m = 27 - 3
5m = 24
m = 24/5

guys pls help me!!!!!!!
Answer:
The answer is t = 17
Step-by-step explanation:
Sum of angles on a straight line = 180⁰
(2t -7) + 90 + 49= 180
(2t -7) +139 = 180⁰
2t -7) = 180 - 139
2t - 7 = 41
2t = 41 - 7
2t = 34
Divide both sides by 2
t = 17

List the characteristics of a proportinonal relationship
Answer:
Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".
The two requirements for a proportional relationship are: The ratio of the two variables maintain the same ratio.

Answer:
[tex]x>17[/tex]
Step-by-step explanation:
We can treat an inequality just the same as an equality in terms of manipulation!(This doesn't hold for multiplying or dividing by negative numbers, but it holds for all addition).
So, we can add [tex]7[/tex] to both sides of the inequality to get [tex]x-7+7>10+7[/tex].
We can simplify [tex]-7+7[/tex] into [tex]0[/tex], and [tex]10+7[/tex] into [tex]17[/tex].

Step-by-step explanation:
Figure B is a scaled copy of Figure A
What is the scale factor from Figure A to Figure B?
Answer:
[tex]1/2[/tex]
Step-by-step explanation:
Because they are scaled copies, the ratios of the sides are equal.
Figure A has a base of 6 units by inspection.
Figure B has a base 3 units by inspection.
So, the scale factor from Figure A to Figure B is [tex]3/6=\boxed{1/2}[/tex] and we're done!
The scale factor from Figure A to Figure B is 1/2
What is the scale factor from Figure A to Figure B?Figure A:
Base = 6 units
Height = 4 units
Figure B:
Base = 3 units
Heights = 2 units
Using Base of the shape:
Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape
= 3 units / 6 units
= 1/2
Using Height of the shape:
Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape
= 2 units / 4 units
= 1/2
Hence, 1/2 is the scale factor from Figure A to Figure B.
