-2x-y=7
Add 2x to both sides
-y= 2x+7
Multiply both sides by-1
Y= -2x-7
2y=x+1
2(-2x-7)= x+1
-4x -14. =x+1
Add 14 to both sides
-4x=x +15
Subtract x from both sides
-5x=15
X=-3
2y =-3+1
-2y=-2
Y=1
(-3,1)
Answer:
The cost of the dress is $240.
Step-by-step explanation:
With the information provided, you can use a rule of three to find the total cost of the dress as you know that $60 represents 1/4 of the total cost of the dress:
60 → 1/4
x ← 1
x=(60*1)/(1/4)
x=(60)/(1/4)
x=(60*4)/(1)
x=240/1
x=240
According to this, the answer is that the cost of the dress is $240.
It’s the third one because its +4 because it’s on the y axis and if you look at a point you go 1 up and 2 to the right so it’s 1/2x+4
What is the solution to 5a+6 -4a=2(a-4)
Answer:
Solve for A by simplifying both sides of the equation, then isolating the variable.
a=14
Point B is located at (-6, 5)
Multiply each coordinate by the scale factor 3 to get
-6*3 = -18
5*3 = 15
The point B' is located at (-18, 15)
