Answer:
(-3,-43) and (3,107)
Step-by-step explanation:
input 25x+32 for y
25x+32=5x²+25x-13
32=5x²-13
-5x²=-45
x²=9
x=+-3
which means you separate the solution
x= -3
x= 3
then input the answers you got for x, in both equations. Then you'll get your y.
y=25(-3)+32
-43
Then check your answer.
Then input the other answer you got for x.
I may be wrong, but I tried and checked my answers.
For number 3, C is the answer.
#4. D
the coefficient of x² is negative, so the graph opens downward.
the two zeros are (3,0) and (5,0)
cannot see the question when editing. I'll post it in the comments.
Your answer is 6 gallons of gas.
Since the car can travel 32 miles per gallon(mpg), you would need to do 192 divided by 32 to get your answer. To verify it you can do 6(answer) times 32. Your answer would be 192, meaning you're right.
Answer:
attached below
Step-by-step explanation:
minus 2 from each side in order to isolate T with the coefficient. To get rid of the coefficient multiply to get 1 which is 5 in this case. Then the answer will be 75
Answer:
0.075(50h)
Step-by-step explanation:
since 0.075 is being multiplied by the cost and the number of hours it takes to repair the printer, you can assume that 0.075 is the tax of repair service.
