Answer:
a,b and dcbecause it equals 1
Step-by-step explanation:
you have to find something that is gonna divide by itself to get a postive number, so d wont work bc it would be 24 divided by 25
Answer:
The answer is B.) 3
Step-by-step explanation:
Answer:
a. 2x -3
b. 7
Step-by-step explanation:
a. The expression that represents the difference is sales between the two sales will be:
9x - (7x + 3) = 9x - 7x - 3 = 2x - 3
b. What we do here is to simply substitute the value of 5 for x
mathematically, we have to substitute the value of 5 in the expression above
We have this as:
2(5) -3
= 10-3 = 7
Answer:
No because it fails the vertical line test. Anytime a choice contains the phrase vertical line test, you give that phrase first consideration. In this case all x values have two y values, and that is the definition of failing the vertical line test.
The answer is D.
The formula of a circle is (x-h)^2+(y-k)^2=r^2, where (h,k) is the center. Since (-7,-1) is the center, we have (x+7)^2+(y+1)^2=r^2. To find the radius, we need to find the distance between (-7,-1) and (8,7). Using the distance formula, we get the radius is 17 (make a right triangle with height 8 and base 15). Now, we have (x+7)^2+(y+1)^2=289. Plug in -15 for x and we have (y+1)^2+64=289. (y+1)^2=225. y+1=+-15. y=14, -16. So the Y is 14 and -16.
