Hi there!
We can solve this equation by using the systems of equations.
We can do this by subtracting like terms from both equations using substitution.
First, let's find the value of y:
6x + 3y = 21
3y = -6x + 21
y = -2x + 7
Then, we should plug it into one of the equations:
3x - 7y = 2
3x - 7(-2x + 7) = 2
3x + 14x - 49 = 2
17x = 51
x = 3
Now, we solve for y by plugging the value of x into the equation:
3x - 7y = 2
3(3) - 7y = 2
9 - 7y = 2
-7y = -7
7y = 7
y = 1
There's your answers.
Hope this helps!
Answer:
L' = (-36, 0)
Step-by-step explanation:
If the point (x, y) is dilated by a scale factor of k about the center (0, 0), then its image is the point (kx, ky)
∵ A dilation has a center (0, 0)
∵ The point L is (-4, 0)
∴ x = -4 and y = 0
∵ The scale factor of dilation is 9
∴ k = 9
→ By using the rule above
∵ kx = 9(-4) = -36
∵ ky = 9(0) = 0
∵ The image of the point L is (kx, ky)
∴ L' = (kx, ky)
∴ L' = (-36, 0)
Answer:
It's 317 miles.
Step-by-step explanation:
You just take the amount of miles it is from her grandparents house and the amount of miles to her cousins house and then you subtract them.
452-135=317 miles apart.
