1. The value of y varies directly with x. If

Mathematics
1 answer:
Maslowich3 years ago
7 0

Answer: x=7

Step-by-step explanation:

To find the value of x, we can set a proportion since the problem states that "y varies directly with x".

\frac{13}{65} =\frac{x}{35}              

Here, we see that the x is the numerator and y is the denominator.

\frac{13}{65} =\frac{x}{35}              [cross multiply]

455=65x          [divide both sides by 65]

x=7

Now, we know that x=7. Logically, we know this is also correct because y=35 is less than y=65. This tells us that x has to be smaller than x=13.

neonofarm [45]

Answer:

24 miles per gallon

Step-by-step explanation:

To find the rate of <u>miles per gallon</u> divide the miles (216) by the gallons (9). 216/9 is 24. So the answer is 24 miles per gallon.

*Miles per gallon is underlined because it gives a hint on how to solve this. Miles per (divide) gallon.

Using the substitution P=1/x and Q=1/y.
erma4kov [3.2K]

Step-by-step explanation:

2p + q = 3 \\ p - 5q = 7 \\  \\ multiply \: the \: second \: equation \: by \: 2 \\  2p - 10q = 14 \\ 2p - 10q - (2p + q) = 14 - 3 \\ 2p - 10q - 2p - q = 11 \\  - 11q = 11 \\ q =  - 1 \\  \\ 2p + q = 3 \\ 2p - 1 = 3 \\ 2p = 4 \\ p  = 2

Which quadratic function has a wider graph than y=2x^2?
Trava [24]

Answer:

y = 1/2 x²

Step-by-step explanation:

The coefficient of the first term in a quadratic, in our case here, x², will tell us how the graph stretches. This is akin to the slope within the linear graph. Similar to the slope, the smaller the coefficient value, or value of slope m, the shallower the angle.

When discussing quadratics, the larger the coefficient of our x² term, the steeper, and skinnier the graph. If we want to look for a graph that is wider than y = 2x², then we need to find a graph with a coefficient that is less than 2.

Our only option then is

y = 1/2 x²
