Answer:
56°
Step-by-step explanation:
hii!
to solve this, we need to know that the angles of a triangle all add up to 180 degrees.
we are going to make an x equation here.
2x+3x+40=180
5x+40=180
-40 -40
5x=140
/5 /5
x=28
angle a is 2x, so the answer would be 28*2 which is 56°
hope this helped out :)
Answer:
6 people
Step-by-step explanation:
75% of 8 is 6
multiply 8 by the decimal .75
The series is increasing by 8 each time.
So that means the complete series is:
1, 9, 17, 25, 33, 41, 49
Add the last 5 digits:
49 + 41 + 33 + 25 + 17 = 165
Answer:
165
1. the answes for the graph ones is the 3rd and 4th graph because both graphs are 1 line and a line is infinite
2. (-3,5) x=(-) y=(+)that means that it must to the left and up part of graph, therefor it is the 4th graph
1. it would be the 4th graph that you didn't show because none of the included answers are correct
Since both are equivalent to y, the equations must be equivalent.
x^2-x-3= -3x+5
x^2+2x-8=0
(x+4)(x-2)=0
x=-4, x=2
Plug the values of x in to either equation
y=-3(-4)+5
y= 12+5
y=17
y= -3(2)+5
y=-6+5
y=-1
Final answer: (-4,17) and (2,-1)
