Answer:
m∠c = 30°
Step-by-step explanation:
Given:
m∠e = 115° and m∠b = 85°
To find:
m∠c
Angle e and angle a are the linear pairs.
By the property of linear pair of angles,
m∠a + m∠e = 180°
m∠e = 180° - m∠a
115° = 180° - m∠a
m∠a = 180 - 115
= 65°
By the property of interior angles of a triangle,
m∠a + m∠b + m∠c = 180°
65° + 85° + m∠c = 180°
m∠c = 180 - 150
m∠c = 30°
Therefore, measure of angles c is 30°.
Answer:
Your answer is Slope-intercept form.
Step-by-step explanation:
Answer: x2+10x-75= (x-5)(x+15)
Step-by-step explanation:
Ok so we factor by thinking of numbers that can add to 10 and multiple to get -75. so those 2 numbers were -5 and 15. Hope this helps xD
Answer:
see below
Step-by-step explanation:
Graph the boundary lines as though these were equations. For the first inequality, which does not include the "or equal to" case, the line is dashed.
Now, look at y in relation to the comparison symbol. For "y < ...", values of y that are in the solution set will be below (less than) those in the line, so the shading is below the line. For "y ≥ ...", values of y that are in the solution set will be above (greater than) those in the line, so the shading is above the line.

The graph of y=2x-1 has a slope of 2 and intersects the y-axis at y=-1. The graph of y=-x+3 has a slope of -1 and intersects the y-axis at y=3.
