-8
the rate of change is -2 and the difference in y from 4 to 8 is 4 so 4 * -2
Answer:
triangle 4.
Step-by-step explanation:
A translation only moves vertically or (and) horizontally our image.
This means that a translation does not change the size
A translation does not rotate the image.
Then a translation of triangle 1 needs to have the same size than triangle 1, and the same "direction" (in triangle 1 we can see that the hypotenuse is at the right side, then in the translated triangle we also should have the hypotenuse at the right side).
Then the only option that seems correct is triangle 4

Answer:
86 cm²
Step-by-step explanation:
<u>1) Calculate the area of the square</u>
Therefore, the area of the square is 400 cm².
<u>2) Calculate the area of the circle</u>
we can substitute with 3.14. To find the radius, we divide the diameter of the circle by 2. 20 cm is the diameter of the circle, so therefore, its radius is 10 cm.
Therefore, the area of the circle is 314 cm².
<u>3) Subtract the area of the circle from the area of the square</u>
Therefore, the area of the shaded region is 86 cm².
I hope this helps!
Its 30 you find the unit rate by 21÷7 which equals 3 then you multipy 3x10 which gives you 30
