Answer:
The measure of angle a is of 140º.
Step-by-step explanation:
Supplementary angles:
If two angles are supplementary, their measures add to 180º.
Angle a and angle b are supplemetary angles.
This means that
<a + <b = 180º.
m angle a = (5x+25) and m angle b = (x+17)
So
Measure of angle a:
The measure of angle a is of 140º.
Answer:
42
Step-by-step explanation:
We want to find the the best estimate for
We round each number to the nearest whole number to get:
Recall that negative times negative gives positive result
This finally gives
Therefore the best estimate is 42
We are given this equation here : 3(2x+8)=6x+8
let us distribute 3 over the bracket using distributive property,
6x+24=6x+8
Here as we can see we have 6x on both sides which will cancel out, so this is the error here and we will have no solution for x.

i dont see a question, sorry
Answer:
y = -1/4x - 3/4
Step-by-step explanation:
First, you need to change the equation into slope intercept form. Subtract 4x from both sides to get -y= -4x + 2. Divide all parts by -1 to get y=4x-2. One thing you should know when finding the slope of a perpendicular line is that the slope is the opposite reciprocal. So, the slope is -1/4. This is your current equation: y= -1/4x + b. Plug the coordinate into the equation; it should look like this: -2= -1/4(5) + b. Multiply -1/4 by 5 to get -5/4. This is what you should have now: -2 = -5/4 + b. Add 5/4 to both sides to get -3/4 = b. Go back to your other equation and plug in -3/4 to b. This is your final equation: y = -1/4x - 3/4. Hope this helped!
