I think you’re right because I put the same thing on my quiz
Answer:
<h2>40°</h2>
Step-by-step explanation:
We have parallel lines.
Angles 1 and 2 are alternate angles.
With parallel lines, alternate angles are congruent.
Therefore
Answer:
Step-by-step explanation:
Co-ordinates of F, G and H are:
F (-4, 5)
G (1, 10)
H (-9, 10)
You can find the lengths of sides by using the distance formula:
<em>length</em>(FG) = 
= 
units
Similarly,
<em>length</em>(GH) = 10 units
<em>length</em>(HF) = 
units
Hence, perimeter will be:
P = <em>length</em>(FG) + <em>length</em>(GH) + <em>length</em>(HF) = 
units
Answer:
step 1. A, B,D are incorrectly written as these are not all coordinates. they must be written (x, y)
step 2. so the question becomes is C a quadratic
step 3. The x values must be evenly spaced. the x values are evenly spaced by a difference of 4
step 4. write out the y values: -126, -14, 2, 18
step 5. write out the differences: 140, 16, 16
step 6. write out the differences: -124, 0.
step 7. after doing this twice the numbers nust be the same for this to be a quadratic which they aren't
step 8. C is not a quadratic.
Answer:
x = 4
Step-by-step explanation:
-3x + 2 = -10x + 30
Add 10x to both sides and you get
7x + 2 = 30
Subtract 2 from both sides and you get
7x = 28
Divide both sides by 7 to get x by itself and you get
x = 4
Reminder whatever you do to one side you have to do to the other side!
Hope this helps!
