__

b. True. A graph of a proportional relationship is a straight line through the origin.

__

c. True. In 5 minutes, the water in the pool will increase by 98.75 gallons, about 100 gallons.

__

d. True. The ratio of a y-value to an x-value will always be 19.75. That is the meaning of this proportional relationship.

__

e. False. The points (8, 158) or (7.5949, 150) will be on the graph. The point (8, 150) will not.

The two lines graphed below are parallel. How many solutions are there to the system of equations?
coldgirl [10]

Solutions just means the amount of times the lines intersect, so there are no solutions. Since the lines are parallel, they’re going the exact same direction forever and ever, never intersecting. Hope this helps!

What two numbers multiply to get 40 and add to get 11
Trava [24]
I got the factors of 40 but both numbers do not add up to 11. Negative numbers are not considered because the product and sum are positive numbers.

1 x 40 = 40    1 + 40 = 41
2 x 20 = 40    2 + 20 = 22
4 x 10 = 40    4 + 10 = 14
5 x   8 = 40    5 +   8 = 13

I also got the addends of 11 and solved each set to get the product
1 + 10 = 11    1 x 10 = 10
2 +   9 = 11    2 x   9 = 18
3 +   8 = 11    3 x   8 = 24
4 +   7 = 11    4 x   7 = 28
5 +   6 = 11    5 x   6 = 30

what is the value of a for the exponential function in the graph represented in the form of f(x)=a(b^x)? Zoom in the photo bcz i
nekit [7.7K]

Answer:

a = 3

Step-by-step explanation:

To determine the value of a, we want b^x to be 1, so that f(x) = a \times 1. Notice that if x = 0, then f(0) = a \times (b^0) = a, so the value of a is simply f(0). From the graph, it appears that f(0) = 3, so therefore a = 3.
