Answer: y = 1/2x -8
Step-by-step explanation:
The equation will be in slope intercept form which uses the formula y= mx +b where m is the slope and b is the y-intercept and those are the only numbers need to write the equation.
The points are (2,-7) (8,-4) to find the slope using these points,find the change in their y values and divide it by the change in the x values.
-7- (-4) = -3
2 - 8 = - 6
-3/-6 = 1/2
So in this case the slope is 1/2, now input it into the equation and use one of the points coordinates to solve for b the y intercept.
-7 = 1/2(2) + b
-7 = 1 + b
-1 -1
b = -8
The y intercept is -8 so we will have the equation y = 1/2x -8
The two numbers are 50 and that should be easy take it as 4 quarters 25+25+25+25 =100 and 100/2 is 50
B) Wires running across the floor
wires are purposly wraped in material that does not conduct electricity, to keep people safe, you may trip over them, but it will not cause electrical accidents
hope that helped!
The <em><u>correct answer</u></em> is:
A.Angle Addition Postulate; Subtraction Property of Equality
Explanation:
The angle addition postulate states that if you place two angles side by side, then the measure of the resulting angle will be equal to the sum of the two original angle measures. This gives us m∠PQR+m∠SQR = m∠PQS.
The next missing justification is for the step that takes 2x+18=100 to 2x=82. In order to get here, we subtract 18 from each side; the property that allows this is the subtraction property of equality.
