45+2a=180. You should always try to write down an equation for problems like these. Subtract the 45 to both sides of the equal sign. This gets you 2a=135. Divide the 2 on both sides and you get a=67.5 degrees. I hope that i helped, enjoy
Answer:
y=-4x+3
Step-by-step explanation:
as x=0
put in y= -4x+3
y= -4(0)+3
y=3
now put x=1 in y= -4x+3
y= -4(1)+3
y= -1
now put x=2 in y= -4x+3
y= -4(2)+3
y=-5
Answer:
<h3>x = 27</h3>
Step-by-step explanation:
Given the expression 
, we are to find the value of x in the expression. This is as shown below;
add 22 to both sides
divide both sides by 2
raise both sides to the power of 3/5
![(x^{5/3})^{3/5} = (243)^{3/5}\\x = (\sqrt[5]{243}) ^3\\x = 3^3\\x = 27](https://tex.z-dn.net/?f=%28x%5E%7B5%2F3%7D%29%5E%7B3%2F5%7D%20%3D%20%28243%29%5E%7B3%2F5%7D%5C%5Cx%20%3D%20%28%5Csqrt%5B5%5D%7B243%7D%29%20%5E3%5C%5Cx%20%3D%203%5E3%5C%5Cx%20%3D%2027)
Hence the value of x is 27
y > 5x-1, because it is just a greater than sign, the shaded area would be to the left of a dotted line.
y ≤ x +3, because the sign is less than or equal to, the line is solid and the shaded area would be to the right.
Combine the shaded areas would make Graph B. the correct answer.
