Hello from MrBillDoesMath!
Answer:
a) See Discussion below
b) Don't know what "m" refers to
Discussion:
Part a)
A triangle contains 180 degrees.
A + B + C = 180 (*)
where A is the angle inside the triangle.
From the diagram
B +C = 62 + 78 = 140
Substituting this in (*) gives
A + (140) = 180 => subtract 140 from both sides
A = 180 - 140 = 40
Now a line has 180 degrees so x + A = 180. But A = 40 (shown above) so x+ 40 = 180, or x = 140. That is, x = 140 - the sum of the measures of the two nonadjacent interior angles
Part b)
I can't answer this part is it is unclear what "m" refers to. Sorry.
Thank you,
MrB
The last one, the format for equations like these would be y=mx+b where m is the slope and b is the y-intercept, and x and y are variables.
Answer:
y = 8
General Formulas and Concepts:
<u>Algebra I</u>
Coordinates (x, y)
Slope-Intercept Form: y = mx + b
- m - slope
- b - y-intercept
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
[Line] x = -3
Point (1, 8)
<u>Step 2: Find Perpendicular Line</u>
<em>A vertical line's slope is undefined. </em>
The negative reciprocal of an undefined slope is 0.
- Define perpendicular slope: <em>m</em> = 0
- Substitute in <em>m</em> [Slope-Intercept Form]: y = 0x + b
- Simplify: y = b
Given point (1, 8), our <em>y</em>-value is equal to 8.
∴ the perpendicular line is y = 8.
Answer:
with what 0-0 are youy okay?
Step-by-step explanation:
First try to isolate the variable, in this case "y". the first step to this is add 5/6 to both sides to get 5y/42=5/6. next multiply each side by 42 to get 5y=35. next divide by 5 to get y=7. so y=7 is the answer.
