Answer:
5
Step-by-step explanation:
firstly, what are complementry angles.complementary angles are angles that su
m up to 90°
(12x-18)+(5x+23)=90
collecting like terms
12x+5x+23-18=90
17x-5-90=0
17x-95=0
17x=95
divide through by 17
x=5
Answer:
y = 10/7
Step-by-step explanation:
(4,2) (-3,1)
slope = (2 - 1)/(4 - (-3)) = 1/7
point-slope form = y - y1 = m(x - x1)
y - 2 = 1/7(x - 4)
or if you want it in slope intercept form:
y = 1/7x - 4/7 + 2
y = 1/7x + 10/7
Hope this helps!
Answer:
y = -2x + 6
Step-by-step explanation:
y = mx + c
Where m is the gradient and c is the y-intercept
m = -2
y = -2x + c
When x = 1, y = 4
4 = -2(1) + c
c = 6
y = -2x + 6
