Answer:
4x + 2y = 7
Step-by-step explanation:
The standard form equation goes as follows: Ax + By = C
We know what A, B, and C is so all we need to do is fill them in.

Answer:
(x+4)(x+18)
Explanation
Let's factor x2+22x+72
x2+22x+72
The middle number is 22 and the last number is 72.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get 22
Multiply together to get 72
Can you think of the two numbers?
Try 4 and 18:
4+18 = 22
4*18 = 72
Fill in the blanks in
(x+_)(x+_)
with 4 and 18 to get...
(x+4)(x+18)
Answer:
(x+4)(x+18)
A) Tonya bought 3 games at X price, so 3X would be total amount.
B) Tony's cost was 0.50 less than X, so x-0.50, he bought 4 games, so he spent 4(x-0.50).
C) Set those to equal to solve for x:
3x = 4(x-0.50)
D) Solve:
3x = 4(x-0.50)
Distribute:
3x = 4x - 2
Subtract 4x from both sides:
-X = -2
Multiply both sides by -1:
X = 2
E) Since X is the amount Tonya paid per game, Tony paid X - 0.50, so Tony paid 2 - 0.50 = $1.50 per game.
Check:
Tonya: 3x = 3(2) = $6 total
Tony: 4(x-0.50) = 4(2.00 - 0.50) = 4(1.50) = $6 total
Answer: See explanation
Step-by-step explanation:
Point slope form: y - y₁ = m (x - x₁)
y₁ = 6
x₁ = -7
y - 6 = -1 (x - [-7])
y - 6 = -1 (x + 7)
y - 6 = -1x - 7
Add 6 to both sides
y = -1x - 1 <em>or </em>y = -x -1
Slope intercept form: y = mx + b
m = -1
b = 6
y = -1x + 6 <em>or </em>y = -x + 6
Standard form: Ax + By = C
Change slope intercept form into _x + _y = c
Slope intercept form: y = -x + 6
Standard form:
y = -x + 6
Add x to both sides
x + y = 6 <em>or </em>-x - y = -6
Hope I helped!
