Answer:
y= -2x-2
Step-by-step explanation:
y=mx + b
y=-2x -2
slope -2 (m=-2) thats your slope
Points are (-3,4) (1,-4)
y2 -y2 -4 - 4 = -8
x2 -x1 1 - -3 = 4
-8/4 simplify
-2/1
Answer:
4 questions
Step-by-step explanation:
90% is the same as multiplying a number by 0.9. Let's say the number of questions on the quiz is x. This means the amount she got right was 0.9x. We are given this is 36, so we can set them equal and simplify:
0.9x = 36
x = 40
She must have gotten 40 - 36, or 4 questions wrong.
Answer:
A
Step-by-step explanation:
regular distance formula is
D= square root (x2 - x1)^2 + (y2-y1)^2
Answer:
16
Step-by-step explanation:
First, simplify by finding the absolute values:
2|-9| - |-2|
2(9) - (2)
Then, simplify this by multiplying 2 and 9:
18 - 2
= 16
So, the answer is 16
Answer:
7.722 cm^2
Step-by-step explanation:
Step 1: Find the area of the square.
- Area of square = s^2, where s = side
- 6^2 = 36 cm^2
Step 2: Find the area of the circle.
- We are given the diameter of the circle as 6 cm, so the radius must be 3 cm.
- Area of circle is , so now we plug in and simplify.
-
-
-
Step 3: Subtract area of circle from area of square.
Therefore, the area of the shaded region is 7.722 cm^2.
