Step 1: Find the slope
Slope formula = (y2 - y1) / (x2 - x1)
---You can choose any two points when finding the slope!
Point 1 = (-2,-10)
Point 2 = (-1,-3)
Slope = (-3 - - 10) / (-1 - - 2)
Slope = 7 / 1
Slope = 7
Step 2: Find the y-intercept
Now that we have the slope, we'll plug that and one point into slope-intercept form. Then, we'll solve for b.
Slope-Intercept Form: y = mx + b
---m is the slope, b is the y-intercept
Point = (-1, -3)
Slope = 7
-3 = 7(-1) + b
-3 = -7 + b
b = 4
Step 3: Put it all together
Now that we know the slope and y-intercept, all that's left to do is plug them into slope-intercept form.
Slope-Intercept Form: y = mx + b
Slope = 7
Y-Intercept = 4
Line: y = 7x + 4
Correct Answer: A

find the area of the quadrilateral.
Answers
Step-by-step explanation:
the area of a triangle is baseline × height / 2.
we have 2 major triangles that define this quadrilateral :
A-D-B and C-D-B.
both triangles have the same baseline : M_D + M_B = 14 cm
what we need to do is get the 2 heights M_C and N_A.
N_A we know already : 8 cm
so,
area A-D-B = 14×8/2 = 14×4 = 56 cm²
M_C we get via Pythagoras of the right-angled triangle D-M-C :
D_C² = M_C² + M_D²
10² = M_C² + 6²
100 = M_C² + 36
64 = M_C²
M_C = 8 cm
so,
area C-D-B = 14×8/2 = 56 cm²
so, the total area of the quadrilateral is
56 + 56 = 112 cm²

We use the sum and difference identities.
Remeber the sum difference identity is
[tex] \sin(x + y) = \sin(x) \cos(y) + \cos( x ) \sin(y) [/tex]
and
[tex] \sin(x - y) = \sin(x) \cos(y) - \sin(x) \cos(y) [/tex]

An analysis of past maintenance costs indicates that maintenance cost is an average of $0.20 per machine-hour at an activity level of 10,000 machine-hours and $0.25 per machine-hour at an activity level of 8,000 machine-hours. If this activity is within the relevant range, what is the total expected maintenance cost if the activity level is 8,700 machine-hours?
Answers
Answer: $2000
Step-by-step explanation:
Variable cost = Change in cost ÷ Activity change
($2000 - $2000) ÷ (10000 - 8000) = $0
Fixed cost element = Final cost - Variable cost
$2000 - ($0.00 ×10000) = $2000
Therefore, the cost formula for total maintenance is $2000 plus $0 per hour
y = $2,000 + $0x
At a level of 8,700 machine-hours, the total cost is:
y = $2000 + ($0.00 ×8700) = $2000
