The answer is 90 i think
explain: none
Answer:
y=0.3x - 7.6
Step-by-step explanation:
line: y=ax+b
a= Δy ÷ Δx
a= (-9 + 7) ÷ (-5 - 2)
a= -2 ÷ -7 = approximately 0.3
y=0.3x + b
Now you can fill in one of the points to find b (or both to make sure you got the answer right).
0.3 × 2 + b = -7
0.6 + b = -7
b = -7 - 0.6 = approximately -7.6
So: an equation of the line that passes through this pair of points is y=0.3x - 7.6
On a test, i would write as many decimals as possible if not said not to, to get the most exact answer. Also remember to keep calculating with the number on your calculator and not to round them off for the most exact answer.
Answer:
x=11 degrees
Step-by-step explanation:
First what you would do is add 6x and 5x-7 to get 11x-7 degrees. Then you double that by using opposite angles theorem to get 22x-14 as the answer of two angles. Next you double 7x-11 to get 14x-22 by using the same theorem as the last one. then you do 14x-22+22x-14=360 degrees then you get your final answer of x=11 degrees
