8 + 3b= -13
-8. -8
3b= -21
Divide by 3
B= -7
Answer:
This is in the form y=mx+b . m is the slope and b is the y-intercept. In this case, the slope is 3 and the y-intercept is −1 .
Answer: Right (Last option)
Step-by-step explanation:
As you can see in the figure, the parallel lines AD and GJ are intersected by two lines.
The line EL intersects the parallel lines and there are two angles that are formed by this intersections which are located on the exterior of AD and GJ, but on opposite sides of EL, (these angles are called "Alternate exterior angles" and they are congruent), which are:
∠LHJ and ∠EBA
You can observe that the angle ∠EBA is indicated with a square. This means that the measure of that angle is 90° (Right angle).
Therefore, if ∠EBA=90°, then ∠LHJ =90°

Step 1: Distribute the subtraction sign to all the numbers in the second set of parentheses...
Step 2: Combine like terms (
's go with 's)
Step 3: Combine like terms (
's go with 's)
Step 4: Combine like terms (normal numbers go with normal numbers)
1 + 2

I don't really know how to explain this one but I got: (7m-6n)(7m-6n)
Answer: 407.25
Step-by-step explanation:
23 x 6.75 =155.25 25 x 4.50 = 112.50 20 x 6.75+4.50=139.50 112.50+155.25+139.50= 407.25 HOPE IT HELPS!!! : )
