Find the slope from the following table:
x y
-7 2
-6 4
-5 6
-4 8
-3 10
-1/2
-2
1/2
2
Answer : 2
Step-by-step explanation:
Slope is a ratio, Slope = rise/run. This can also be described as "the change in Y" / "The change in X"
So, using the table, find the rate of change in the y-values and the x-values.
y = mx + b
slope : m
x=-7, y=2 : -7m + b = 2 (1)
x=-6, y=4 : -6m + b = 4 (2)
(2)-(1) => m= 2

Answer:
x = 12
perimeter = 124
Step-by-step explanation:
The midline RS is half the length of MN, so we have ...
2×RS = MN
2(x +3) = 5x -30
2x +6 = 5x -30
36 = 3x . . . . . . . . . add 30-2x
12 = x . . . . . . . . . . divide by 3
__
The length RS is then ...
RS = x +3 = 15
and the perimeter of QRS is ...
P(QRS) = QR +RS +SQ = 25 +15 +22 = 62
The perimeter of QRS is half the perimeter of MNP, so ...
P(MNP) = 2×P(QRS) = 2×62 = 124
The perimeter of ΔMNP = 124.

What is Triangle?A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.
here, we have,
A median divides the area of a triangle into two equal parts. The first median, CM, divides triangle ABC into two equal areas, AMC and BMC. The second median, BD, divides triangle BMC into two equal areas, BMD and CDB.
We're given that ABMD = 3 cm², so ACDB is also 3 cm². The sum of those two areas is ABMC, which is also AAMC, 6 cm².
Median AD also divides ΔAMC in half, so AADC = 3 cm² and AADM = 3 cm². AABD is the sum of ABMD (3 cm²) and AADM (3 cm²) so is 6 cm².
AABC is the sum of the smaller areas, so is 12 cm².

15. Over the summer, Paulo opens a dog-washing
business and begins with $32. The table shows how
much he earns and spends each week. He works for
8 weeks washing dogs. When he starts back at school,
he budgets $60 to spend each week. How many
weeks pass before he needs to wash more dogs?
Using the information given in the table, the number of weeks that would pass before more dogs would have to be washed is 16 weeks.
Given the Parameters :
Initial start up = $32 Number of weeks worked = 8Recall :
Profit = Revenue - ExpensesProfit made per week = $124 - $8 = $116
Total amount of profit made :
Profit made per week × Number of weeks. Total profit made = $116 × 8 = $928
Total amount owned = Total profit made + Initial start upTotal amount owned = $928 + $32 = $960
Number of weeks before total amount owned is expended can be calculated thus :
Total amount owned ÷ spending per weekNumber of weeks = ($960 ÷ $60) = 16
Hence, 16 weeks will pass before more dogs would have to be washed.

Step-by-step explanation:
Use foil method
(10 - 3i) (2 -5i) = 10*2 + 10*(-5i) + (-3i)*2 + (-3i)*(-5i)
= 20 - 50i -6i + 15i²

Equation at the end of step 1
(3a + 2) • ((22a2 - 2a) + 9)
STEP
2
:
Trying to factor by splitting the middle term
2.1 Factoring 4a2-2a+9
The first term is, 4a2 its coefficient is 4 .
The middle term is, -2a its coefficient is -2 .
The last term, "the constant", is +9
Step-1 : Multiply the coefficient of the first term by the constant 4 • 9 = 36
Step-2 : Find two factors of 36 whose sum equals the coefficient of the middle term, which is -2 .
-36 + -1 = -37
-18 + -2 = -20
-12 + -3 = -15
-9 + -4 = -13
-6 + -6 = -12
-4 + -9 = -13
For tidiness, printing of 12 lines which failed to find two such factors, was suppressed
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
(3a + 2) • (4a2 - 2a + 9)

Calculate the unit rate for Machine A and Machine B. Determine which is the greater rate.
I need help on this, asap‼️
Answer:
A: 2 1/2 ft^2/h
B: 3 1/3 ft^2/h
B has the greater rate
Step-by-step explanation:
The rate in square feet per hour is found by dividing square feet by hours.
Machine A:
(5/8 ft^2) ÷ (1/4 h) = (5/8)×(4/1) ft^2/h = 5/2 ft^2/h = 2 1/2 ft²/h
Machine B:
(2/3 ft^2) ÷ (1/5 h) = (2/3)×(5/1) ft^2/h = 10/3 ft²/h = 3 1/3 ft²/h
Machine B has the greater rate.

Question 5 options:

y=35x+135

Answer:
the answer to the first question is B.
Step-by-step explanation:
Find the equation of a line that has the same slope as y = 5 - 9x and the same y-intercept as y=-8x - 10.
Answer:
y=-9x-10
Step-by-step explanation:
First, start by putting the first equation into slope intercept form:
y=-9x+5
We know that in the standard slope intercept formula (y=mx+b), m is the slope and b is the y intercept. Thus, line with the same slope as the one above would have a slope of -9.
To have the same y intercept as y=-8x-10, the y intercept would have to be -10.
Therefore, the formula would be y=-9x-10
Answer:
y = - 6/5x + 8/9
Step-by-step explanation:
For this case we have that by definition, the equation of the line of the slope-intersection form is given by:
Where:
m: It is the slope of the line
b: It is the cut point with the y axis
We have the following equations:
Equation 1:
By definition, if two lines are perpendicular then the product of their slopes is -1:
Equation 2:

Answer:
y = -2/3x + 2
have a good day :3
Step-by-step explanation:
we need to bring it into the form
y = ax + b
so,
2x + 3y = 6
3y = -2x + 6
y = (-2/3)x + 2
the slope is the factor of x (-2/3). the y-intercept is 2 (meaning y = 2 for x = 0).

Step-by-step explanation:
1/2 | 5x-15| = 10
Multiply each side by 2
1/2 *2 | 5x-15| = 10*2
| 5x-15| = 20
Absolute value equations have two solutions, one positive and one negative
5x-15 = 20 5x-15 = -20
Add 15 to all sides
5x-15+15 = 20+15 5x-15 +15 = -20+15
