Answer:
130
Step-by-step explanation:
1 and 2 form a straight line, so they are supplementary. That means they add up to 180. So,
a1+a2=180
50+a2=180
a2=130
Answer:
it would be B.130
Step-by-step explanation:
considering an angle can only go to 180* subtract 50 from 180 and you get 130
Write an equation in slope-intercept form for the line passing through the two points (0,-2) and (3,0)
Answer:
y = (2/3)x - 2
Step-by-step explanation:
This problem is interesting in that both the x- and the y-intercepts are given. The y-intercept is (0, -2), and so 'b' in 'y = mx + b' must be -2:
y = mx - 2. The x-intercept is (3, 0), so we know that y = 0 when x = 3:
0 = m(3) - 2
This latter result must be solved for m: 3m = 2, or m = 2/3.
Then the desired equation is y = (2/3)x - 2.
6=2(y+2) solve for what is y?
Answer:
y is 1
Step-by-step explanation:
Answer:
y = 1
Step-by-step explanation:
First divide both sides by 2
this gives you 3 = y+2
then subtract 2 from each side giving you y = 1

Answer: Read the Explanation
Step-by-step explanation:
m<7 = 120
m<5 = 120
m<6 = 60
m<2 = 60
The reason why they are 60 is because they are supplementary angles to complete a straight line so like since 3 = 120 4 = 60 since its a straight line.

Given f(x)=-x+6 write an equation for f(x-2)
Answer:
f(x - 2) = - x + 8
Step-by-step explanation:
Substitute x = x - 2 into f(x)
f(x - 2) = - (x - 2) + 6 = - x + 2 + 6 = - x + 8

The population of a place was 56000. Next 5 years it is expected to rise by 50%. What will be the population in next 5 years?
Answer:
84000 people
Step-by-step explanation:
So next 5 year wil be 56000 + 50%
56000 = 100%
50% = 56000 / 2
50% = 28000
56000 + 28000 = 84000

What is the solution to 1/2 |x| = -3
Options:
x = -6
x = -6 or x = 6
x = -6 or x = 2
No solutions exist.
Answer:
No solution
Step-by-step explanation:
multiplying both sides by 2 gives |x|=-6 but an absolute value can't be negative so there are no solutions

quick question is this area or perimeter?
Answer:
2 and 3
Step-by-step explanation:
to be similar, there must have been the same scaling factor applied for length and width.
when going from 2 to 3 the width changes from 5 to 7, that is a changing factor of 7/5 = 1.4
and the length changes by the same factor :
6.5 × 7/5 = 1.3 × 7 = 9.1

Anyone helps me pleaseeeeee✨
I will so so so love you if you help me to solve it!!!!!!!!!
Answer: Hope it helps :)
Step-by-step explanation:
The essential thing to learn from this lesson is the translation of equations. When f(x) = f'(x) + a, the graph of the equation is shifted up by a units.
When f(x) = f'(x + a), the graph of the equation is shifted left by a units.
