Answer:
y = 6/5x - 2 (or y = 1.2x - 2)
Step-by-step explanation:
To find the slope-intercept form ( = mx + b) you need to rearrange the equation of the line:
Step 1 - Add 18x to both sides
15y = 18x - 30
Step 2 - Divide both sides by 15.
y = 6/5x - 2
1/2 ( or any equivalent fractions ) or 50% !
Answer:
∠ WXY = 20°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ XYZ is an exterior angle of the triangle, thus
10x - 5 = 3x + 17 + 3x + 2
10x - 5 = 6x + 19 ( subtract 6x from both sides )
4x - 5 = 19 ( add 5 to both sides )
4x = 24 ( divide both sides by 4 )
x = 6
Thus
∠ WXY = 3x + 2 = 3(6) + 2 = 18 + 2 = 20°
Answer:
14h+15
Step-by-step explanation:
(7h + 7) + (7h + 8)
First simplify
Eliminate redundant parentheses
(7h+7)
7h+7+7h+8
Add the numbers
7h+(7)+7h+(8) . 7+8=15
7h+15+7h
Combine like terms
(7h)+15+(7h) (7h)+(7h)=14h
14h+15
The answer would be 14h+15
Answer:
x=90
y=148
Step-by-step explanation:
Since we know a line is 180 degrees, and we know that angle Q is 90, x must be a 90-degree angle as well.
With our given information we can add up the two given angles in the triangle which are 90 and 58
90+58=148
To find what R is, we must subtract 148 from 180 because all the angles in a triangle sum up to 180.
180-148=32
Now that we know that R is 32, because we know that a line is 180 degrees, we can subtract 32 from 180 to get our final answer for y as 148.
180-32=148
