Answer:
12
Step-by-step explanation:
plug in -7 where x is
5 - (-7) = 12
Applying the segment addition postulate:
x = 2.75
AB = 6x = 6(2.75) = 16.5 units
BC = 8x + 1/4 = 8(2.75) + 1/4 = 22.25 units.
<h3>What is the Segment Addition Postulate?</h3>
Based on the segment addition postulate, since B lies between points A and C on a line segment, then:
AB + BC = AC
AC = 38 3/4
AB = 6x
BC = 8x + 1/4
Substitute
6x + 8x + 1/4 = 38 3/4 [segment addition postulate]
14x + 1/4 = 155/4
14x = 155/4 - 1/4
14x = (155 - 1)/4
14x = 154/4
14x × 4 = 154
56x = 154
x = 154/56
x = 2.75
AB = 6x = 6(2.75) = 16.5 units
BC = 8x + 1/4 = 8(2.75) + 1/4 = 22.25 units.

Answer:
y = -4x + 5
Step-by-step explanation:
This linear function can be represented through the slope-intercept form, or y=mx+b. You already know your m value, 4, which is your slope. From there you can plug in your coordinate into the y and x values to find your y-intercept, or b.
y = mx + b
-3 = -4(2) + b
b = 5
Then you put it all together to form the equation f(x) = -4x + 5
To answer this you’d have to use an 2 step equation 145x= 1000
When u get the answer for x multiply the answer by the erasers original area to find the area of the eraser it would be lengthtimes width times height
90°, since the two line segments are perpendicular to each other.
