Parallel lines have the same slope.

We have y=\dfrac{1}{2}x-7.

Therefore we have y=\dfrac{1}{2}x+b

We must find b. We know, the line passes through (-3, -2).

Substitute the values of point to the equation of the new function:

-2=\dfrac{1}{2}(-3)+b\\\\-2=-1.5+b\qquad|\text{add 1.5 to both sides}\\\\-0.5=b\to b=-0.5\to b=-\dfrac{1}{2}

Answer: y=\dfrac{1}{2}x-\dfrac{1}{2}

Can u help me find the answer to #5 and 6​
Arlecino [84]

Answer:

5) x = 24

6) x = 48

Step-by-step explanation:

I'd be glad to help :)

For question 5, we know that 62 and the unknown angle is a straight angle, so 62+y = 180. y = 118. We also know all the angles in a triangle add up to 180, so x+(x+14)+118 = 180. Therefore, 2x+132 = 180. We now know that 2x = 48, so x = 24 for question 5.

For question 6, We know that because the line is divided up, (x+35) can be moved down a line, so (2x+1)+(x+35) = 180, so 3x+36 = 180. We now know that x = 48 for question 6

The solution to the question????
vivado [14]
Hey there !

\dfrac{3}{2} = \dfrac{3}{2x} - \dfrac{6}{5x} \\ \\ \dfrac{3}{2} = \frac{15 - 12}{10 {x}^{} } \\ \\ \frac{1}{2} = \frac{1}{10x} \\ \\ x = \frac{1}{5} \: \: \: \: \: \: \: \: Ans.
Hope it helps you :)
