Answer:
D
Step-by-step explanation
You multiply 7x2 first, that equals 14. Then you add 13+4, which equals 17. You then subtract those two and get 3.
Answer:
The answer would be 3x + 4y = -14
Step-by-step explanation:
First we need to find the slope of the original line. We can do this by solving for y.
6x + 8y = 9
8y = -6x + 9
y = -3/4x + 9/8
Now we can use that slope (-3/4) and the point in point-slope form to get the answer. You'll need to solve for the constant.
y - y1 = m(x - x1)
y - 1 = -3/4(x + 6)
y - 1 = -3/4x - 9/2
3/4x + y - 1 = -9/2
3/4x + y = -7/2
3x + 4y = -14
Answer:
Option B
Step-by-step explanation:
First identify which options are a match for the hyperbola with a foci of (- 12, 6) and ( 6, 6 ). If there is only one, we can claim that that is the solution. Otherwise we would have to take the vertices into account,
The first option can be eliminated as it is present with a decimal in the denominator, indicating that the foci should also be a decimal. However, the foci of this option should be valuable to us -
The second option squares the denominators of the first option, so the foci should be the following -
Which is the given! The rest of the options are similar to this second option, but are altered, thus don't have the same foci,
<u><em>Solution = Option B</em></u>
Answer:
6.7 km
Step-by-step explanation:
c² = 4.9²+4.5²
= 24.01 + 20.25
= 44.26
c = √44.26 = 6.7
Answer: The slope, 20, represents the miles driven per gallon of gas. The y-intercept is 0, it represents the number of miles driven after 0 gallons.
Explanation:
(100-0)/(5-0)=20
(160-100)/(8-5)=20
(180-160)/(9-8)
