Answer:
y - 8 = -2(x - 9)
Step-by-step explanation:
Given the slope, m = -2, and the point, (9, 8):
Let (x₁, y₁) = (9, 8)
slope (m ) = -2
We can substitute these values into the following point-slope form:
y - y₁ = m(x - x₁)
y - 8 = -2(x - 9) ⇒ This is the point-slope form.
-3 + c/3 =12
A.-45
B. 45
C. 27
D. -27
Answer:
B. 45
Step-by-step explanation:
-3 + c/3 = 12
c/3 = 12+3
c/3 = 15
c = 15×3
c = 45
Answer:
45
Step-by-step explanation:
-3 + c/3 = 12
c/3 = 12 + 3
c/3 = 15
c : 3 = 15
c = 15 . 3
c = 45

Step-by-step explanation:
percent change of 10 and 24
Answer:
140%
Step-by-step explanation:
(24-10) / 10 = 14/10 = 140%
Answer:
140%
Step-by-step explanation:
A change from 10 to 24 represents a positive change (increase) to 140%.
Percent change = New-Old/Old x 100%
Percent change = 24-10/10 x 100% =
14/10 x 100 = 140% (increase)
Where 10 is the old value and 24 is the new value. In this case, we have a positive change (increase) of 140 percent because the new value is greater than the old value.

Answer:
1. 42 people can be seated
2. 16 tables should be used.
Step-by-step explanation:
Part 1:
Since we are given the function, p(n) = 4n + 2, we need to plug in 10 to "n." This is because "n" represents the number of tables as stated on the top of the pciture. And "p(n)" represents the number of people that can be seated.
p(n) = 4(10) + 2
p(n) = 40 + 2
p(n) = 42
Part 2:
For this question, since we are given 65 as the total number of people that can be seated, we would plug in 65 in "p(n)", to result in the following equation.
p(65) = 4n + 2
Then solve the equation and use the property of inverse operation.
65 = 4n + 2
65 - 2 = 4n + 2 - 2
63 = 4n
63/4 = 4n/4
15.75 = n
Although we're given 15.75 as the number of tables that should be used, we can't really have a 0.75 of a table, so we would round 0.75 to 1.
15 + 1 = 16
16 tables are required.

Step-by-step explanation:
-5g -6
Let g= -2
-5 (-2) -6
Multiply
10 -6
4
Answer:
A. 4
Step-by-step explanation:
So, we have an equation with a variable (g), and they've given us the value of g to be -2. All we have to do at this stage is plug in the value of g into the equation.
-5g-6 (g=-2)
-5(-2)-6
10-6=4
Doing the math by plugging in -2, you would get your answer to be 4. Let me know if you see any errors, and if you have any further questions at all.
4q^2 -(qr + 25); if q = 6 and r= 19
Answer:
5
Step-by-step explanation:
q = 6
r = 19
4q^2
= 4 x q^2
= 4 x 6^2
= 4 x 6 x 6
= 144
qr
= q x r
= 6 x 19
= 114
qr + 25
= 114 + 25
= 139
4q^2 - ( qr + 25 )
= 144 - 139
= 5
1. Write a polynomial function of least degree with rational coefficients so that P(x)=0 has the given roots.
x = -4, x= 8
2. A polynomial function p(x) with rational coefficients has the given roots. Find two additional roots of p(x)=0.
18-square root of 7 and 4i
3. Find all the zeros for the following function.
Y=x^3-5x^2+9x-45
1. If a polynomial function with rational coefficients has -4 and 8 as roots, it means we can factor this polynomial this way :
(x - (-4))(x-8) = (x+4)(x-8) = x² - 8x + 4x - 32 = x² - 4x - 32
1x² - 4x - 32 is a polynomial function of least degree with rational coefficients that satisifies the given conditions. The leading coefficient here is 1, we call this a monic polynomial.
2. There may be something missing in the question here
3. We can use the factoring techniques to find the roots :
x^3 - 5x² + 9x - 45 let us group x^3 with -5x² and 9x with -45 :
(x^3 - 5x²) + (9x - 45) = x²(x - 5) + 9(x - 5)
We can notice now that there is a common factor : (x-5) this allows us to factor again by (x-5) :
Y = (x-5)(x²+9)
This is the maximum we can do on R, but on C the set of complex we can still factor again.
x² + 9 has a negative discriminant : Δ = b² - 4ac where b = 0 , a = 1, c = 9
Δ < 0, Δ = - 36
Applying the formulas for the roots x1 and x2 we get x1 = -3i, and x2 = + 3i
Y = (x-5)(x-3i)(x+3i)
So the solution is S = {5, 3i, -3i} the three roots of the function.

Tell whether the lines through the given points are parallel, perpendicular, or neither.
Line 1: (6, 5), (4,2)
Line 2: (-8, -1), (-2, 8)
Answer: Line 1: (2, 3) , (4, 12)
m = (12 - 3)/(4 - 2) = 9/2 This is the slope of the line
y = (9/2)x + b
3 = (9/2)(2) + b
3 = 9 + b
b = -6
y = (9/2)x - 6
Line 2: (5, 10) , (14,8)
m = (8 - 10)/(14 - 5) = -2/9
this slope is the opposite sign, and inverse of the first equation's slope. Therefore, the line is perpendicular.
y = mx + b
8 = (-2/9)(14) + b
8 = -28/9 + b
11.11 = b
y = (-2/9)x + 11.11
Step-by-step explanation: Hope this helps :)

Select the correct answer Which equation represents a line that is perpendicular to line MN?
Answer:
D. y = 4x - 6
Step-by-step explanation:
The equation that is perpendicular to the line MN should have a slope that when multiplied by the slope of line MN will result to negative one. Therefore,
Therefore,
m₁ × m₂ = -1
Using the 2 coordinates of MN let's find the slope,
(-7, 6)(5, 3)
Therefore,
m₁ = 3 - 6 / 5 - (-7) = -3 / 12 = - 1 / 4
The equation that represent a line perpendicular to the line MN is
y = 4x - 6 because the slope slope(m₂) is 4.
From our formula,
4 × - 1 / 4 = - 1
So, option D meets the requirement.

D. y = 4x - 6

8x+y=9, 33y+6x=190, what is the value of x and y?
Answer:
x = 0.414729
y = 5.6822
Step-by-step explanation:
We can solve this by either of two mwethods: Solve the equations directly, or graph them to find the point they intersect (the only solution that satisfies both equations).
SOLVE
33y+6x=190
8x+y=9
y = 9-8x
Substitute this value of y in the first equation:
33y+6x=190
33(9-8x)+6x=190
297-264x+6x=190
-264x+6x=190-297
-258x = -107
x = (107/258)
x = 0.414729 Use this value of x to solve for y (in either equation)
8x+y=9
8(0.414729)+y=9
3.317829 + y = 9
y = 5.6822

write 5 square root values that are between 9 and 10 explain your strategy
Answer:
sqrt(x) where x is between 81 and 100; example sqrt(88). See explanation for more examples.
Step-by-step explanation:
9=sqrt(81) and 10=sqrt(100)...
So the square root(x) is between 9 and 10 if x is between 81 and 100.
Here are examples:
sqrt(82)
sqrt(83)
sqrt(85.6)
sqrt(92)
sqrt(94)
sqrt(97)
sqrt(99)
sqrt(99.6)
So again the answer is just anything in form sqrt(x) where x is between 81 and 100. The reasoning is because sqrt(81)=9 and sqrt(100)=10 which puts the values we stated between those values.

Donald Brooks bought a desk for $125.
After spending $75 on repairs, he sold the
desk for $350. What was his percent of
profit based on the cost?
Answer:
75%
Step-by-step explanation:
The total cost was $125 + $75 = $200
The selling price was $350.
The profit was $350 - $200 = $150
The percent profit was 150/200 * 100% = 75%
