Answers:
x intercept is (-7.5, 0)
y intercept is (0, 5.5)
=========================
How to get these answers:
Simply look at where the graph crosses the x axis to determine the x intercept. This is directly halfway between the -8 and -7, so the line crosses through -7.5 on the x axis meaning that the x intercept is located at (-7.5, 0)
Similarly, the y intercept is (0, 5.5) as it crosses exactly halfway between the 5 and 6 on the y axis.
Any point is of the form (x,y)
The x intercept always has y = 0. The y intercept always has x = 0.
Answer:
96
Step-by-step explanation:
O is double D. And A is equal to O. Hence 2*48=96
Answer:
105 cc of 7% solution
245 cc of 17% solution
Step-by-step explanation:
If x = volume of 7% solution, and y = volume of 17% solution, then:
x + y = 350
0.07x + 0.17y = 0.14(350)
Solve with substitution:
0.07x + 0.17(350 − x) = 0.14(350)
0.07x + 59.5 − 0.17x = 49
10.5 = 0.10x
x = 105
y = 245
Answer:
A
Step-by-step explanation:
Slope is the first y - the second y divided by the first x- the second x. Therefore we take -8-4= -12 and -7-0= -7. Using the formula, we get -12/-7. The negatives cancel out and we get 12/7 which is A.
