Answer:
39
Step-by-step explanation:
the equation is:
4x - 15 + x = 180
4x + x - 15 = 180
5x - 15 = 180
+15 = +15
5x - 0 = 195
5x/5 = 195/5
x = 39
(4x - 15) + x
(4(39) - 15) + 39
(195 - 15) + 39
141 + 39
180
A circle has 360 degrees but in the problem you are using half of it. You 180 that's why the whole equations has to equal 180 to be right.
(2/4)= 1/2 ; 15/20= 3/4; 6/18=1/3
Answer:
y=-2x+2
slope-intercept form --> y=mx+b
m= slope. the slope in the graph is down 2 over 1, -2/1 which is the same as -2.
b = <u>y-intercept</u><u>. </u><u> </u><u>the </u><u>y-intercept</u><u> </u><u>is </u><u>2</u><u>.</u>
Answer:
(1,0)
Step-by-step explanation:
It would be answer A because answer A has the same slope as the equation in the question, none of the other answers have the same slope as 7/6. there is -7/6, but all that means is that the equation is negative. we need a positive equation.
