Answer:
y = 0
Step-by-step explanation:
Y = 40 + 4m
m = minutes
y = total papers graded
Answer: y = -4x/5 + 13
Step-by-step explanation:
The equation of a straight line can be represented in the slope intercept form as
y = mx + c
Where
c represents the y intercept
m represents the slope of the line.
The equation of the given line is
y = 5x/4 - 2
Comparing with the slope intercept form, slope = 5/4
If two lines are perpendicular, it means that the slope of one line is the negative reciprocal of the slope of the other line.
Therefore, the slope of the line passing through (10, 5) is - 4/5
To determine the y intercept, we would substitute m = - 4/5, x = 10 and y = 5 into y = mx + c. It becomes
5 = - 4/5 × 10 + c
5 = - 8 + c
c = 5 + 8 = 13
The equation becomes
y = -4x/5 + 13
Answer:
<h3>A). AC is congruent to XZ </h3>
<em><u>Given </u></em><em><u>-</u></em><em><u> </u></em> angle X = angle A
angle Z = angle C
<em><u>To </u></em><em><u>find </u></em><em><u>-</u></em><em><u> </u></em>criteria of congruence
<em><u>Solution </u></em><em><u>-</u></em><em><u> </u></em>
In triangle BAC and triangle YXZ
angle X = angle A
angle Z = angle C
we need one pair of side to be comgruent to show the following traingles congruent
if AC is congruent to XZ
then by angle side angle criteria of triangle both the triangles are congruent..
