Answer:
Step-by-step explanation:
x is the amount of hours it will take. Since he pays $30 per hour, your answer would be 30x + 525
We have points (-3, 4), (-1, 2), (4, -3) and (6,-5)
Let's verify it's a line by calculating the slopes between successive points.
Slope is change in y over change in x.
(2 - 4)/(-1 - -3) = -2/2 = -1
(-3 - 2)/(4 - -1) = -5/5 = -1
(-5 - -3)/(6 - 4) = -2/2 =-1
Yup. We have a line of slope -1 through point (-1, 2)
y - 2 = -1(x - -1)
y = -x - 1 + 2
y = -x + 1
That's the linear equation for the table.
Answer: Linear equation: y = -x + 1 slope = -1
Answer:
The answer is choice B: 22.52 units.
Step-by-step explanation:
We use the Pythagoras's theorem which says for a right triangle with sides
and hypotenuse
:
![x^2+y^2=z^2.](https://tex.z-dn.net/?f=x%5E2%2By%5E2%3Dz%5E2.)
In our case
![z=26](https://tex.z-dn.net/?f=z%3D26)
![y=13](https://tex.z-dn.net/?f=y%3D13)
So we solve for ![x:](https://tex.z-dn.net/?f=x%3A)
![x=\sqrt{z^2-y^2}=\sqrt{26^2-13^2} =\boxed{22.52\: units.}](https://tex.z-dn.net/?f=x%3D%5Csqrt%7Bz%5E2-y%5E2%7D%3D%5Csqrt%7B26%5E2-13%5E2%7D%20%20%3D%5Cboxed%7B22.52%5C%3A%20units.%7D)
Which is choice B.
Answer: Both A, and C
Step-by-step explanation:
The answer to the first system of equations (2x+2y=16) would be
x=3 and y=5 ( 3x-y=4 )
Which means we have to find out which of the other equations has an x value of 3, and a y value of 5.
If A is 2x+2y=16, then x=3 and y=5
6x-2y=8
If B is x+y=16, then x=5 and y=11
3x-y=4
If C is 2x+2y=16, then x=3 and y=5
6x-2y=8
If D is 6x+6y=48 , then x=-2 and y=10
6x+2y=8
Both A and C are equal to the first system of equations, which means they are both correct answers.
