Answer:
70:) i think that’s the right answer.
Step-by-step explanation:
You have that the scale factor is 8 and the length of the figure is 10 yards. Therefore, to solve this exercise, and calculate the length of the image, you must follow the proccedure below:
1. If the scale factor is 8, this means that lenght of the image is 8 times bigger.
2. Keeping this on mind, you only have to multiply 8 by 10 yards, as below:
Length of the image=8x10 yards
Length of the image=80 yards
3. Therefore, the answer is the option C:
C. 80 yd
Answer:
Step-by-step explanation:

To isolate the term of x from one side of the equation, you must multiply by a polynomial.


<u>You have to solve with parentheses first.</u>

<u>Solve.</u>

x(-5x)=-5x²

3*3x²=9x²
3(-5x)=-15x
3(-10)=-30
<u>Then, rewrite the problem down.</u>

<u>Combine like terms.</u>

<u>Add/subtract the numbers from left to right.</u>
-5x²+9x²=4x²

<u>Solve.</u>

<u>Then rewrite the problem.</u>

- <u>Therefore, the correct answer is 3x³+4x²-25x-30.</u>
I hope this helps! Let me know if you have any questions.
Answer:
y = -1/2x +11/2
Step-by-step explanation:
slope finding: -5+6/1-3 = -1/2
equation making: y+5 = -1/2(x-1)
rearranging: y = -1/2x +11/2
Answer:
80.
Step-by-step explanation:
When multiplying if the tenth place is " 7" then we look " next door" which is the ones and 8 is great then 5 so we count to from 8 to see when the next number ending in 0 would be in this case its 80. ( if the number is 4 or less count backwards to a number ending with 0 which in that case would have been 70 ) but the answer is 80.
