Answer:
Step-by-step explanation:
- 20 - 15(2²· 5/4) = Exponent
- 20 - 15(4 · 5/4) = Parenthesis
- 20 - 15(5) = Multiplication
- 20 - 75 = Subtraction
- - 55
Answer:
2x - 3y = 18
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 2x - 3y = - 3 into this form by subtracting 2x from both sides
- 3y = - 2x - 3 ( divide all terms by - 3 )
y =
x + 1 ← in slope- intercept form
with slope m = 
Parallel lines have equal slopes, thus
y =
x + c ← is the partial equation
Given the y- intercept = 6, then
y =
x + 6 ← equation in slope- intercept form
Multiply through by 3
3y = 2x + 18 ( subtract 3y from both sides )
0 = 2x - 3y + 18 ( subtract 18 from both sides )
2x - 3y = - 18 ← equation in standard form
Answer:
110 degrees
Step-by-step explanation:
The 23x + 1 angle is supplementary (adds to 180) to 36x + 2 so that means
23x + 1 + 36x + 2 = 180
Which in turn means : x = 3
Which then means : Bold angle = 36 * 3 + 2 = 110
Plug in x and y into the equations and see which one comes out true...
