Determine if the ordered pair (1,-3) is a solution to the system of equations below:
y = x - 4
y = 9x - 12
Answer:
Yes, it is a solution
Step-by-step explanation:
(x,y) (1,-3)
a. Plug in x:
y= 1-4
y = -3 yes this is correct as -3 is on y.
b. Plug in X.
y=9(1)-12
y=9-12
y=-3 yes this is also correct as this also is -3 for y.

8.2 meters (8.18 without rounding)
Step-by-step explanation:
27 divided by 3.3 = 8.2 meters
The Keatings have several bird feeders in their yard. They started with a 10.5-pound bag of birdseed. After 2 months, 12 ounces remained. What is the percent of change in the amount of birdseed after two months? Round your answer to the nearest tenth of a percent if necessary.
Answer:
[tex]92.9\%[/tex]
Step-by-step explanation:
Initial amount of birdseed = 10.5 pounds
Final amount of birdseed = 12 ounces
[tex]1\ \text{ounce}=\dfrac{1}{16}\ \text{pounds}[/tex]
[tex]12\ \text{ounces}=\dfrac{12}{16}=0.75\ \text{pounds}[/tex]
Percentage change in the amount of birdseed is
[tex]\dfrac{\text{Initial-Final}}{\text{Initial}}\times 100\%=\dfrac{10.5-0.75}{10.5}\times 100\%\\ =92.9\%[/tex]
The percentage of birdseed that changed is [tex]92.9\%[/tex]

Answer:
8. 4 +2q²/p² -4r/p +r²/p²
9. (x, y) = (3/4, -17/8)
Step-by-step explanation:
All of these questions are asking you to make use of the fact that ...
α + β = -q/p
αβ = r/p
__
8. (2 +α²)(2 +β²) = 4 + 2(α² +β²) +α²β²
= 4 +2((α+β)² -2αβ) +(αβ)²
Substituting the above for the sum and product, you have ...
= 4 + 2((-q/p)² -2(r/p)) +(r/p)²
= 4 +2q²/p² -4r/p +r²/p²

9. This is asking for the vertex of the parabola. The x-coordinate is ...
x=-b/(2a) = -(-3)/(2(2) = 3/4
Then the y-coordinate is ...
y = (2(3/4) -3)(3/4) -1 = (-3/2)(3/4) -1 = -9/8 -1 = -17/8
The (x, y) values of interest are (3/4, -17/8).
Please use y=mx+b form or else it won’t work

Fran and Winston have a combined income
of $80 000. One quarter of Winston's income
is the same as one-sixth of Fran's income.
How much does each person earn?
Answer:
Winston:$32,000
Fran:$48,000
1 of 4 parts is equal to 1 of 6 parts so if you add 4 parts to 6 parts you get 10. Divide the total amount by 10 and you get 8000. multiply 8000 to the amount of parts each person gets and you get that.

The volume of a right circular cone is 300 cubic inches. What is the volume, in cubic inches, of a right cylinder that
has the same base and height as the cone?
Answer:
900 cubic inches.
Step-by-step explanation:
Given the following data;
Volume of right circular cone = 300in³
We know that the volume of a right circular cone is given by the formula;
[tex] V = \frac {1}{3} \pi r^{2}h[/tex]
Where;
V is the volume of right circular cone. r is the radius of the base of the right circular cone. h is the height of the right circular cone.The volume of a right circular cylinder is given by the formula;
[tex] V = \pi r^{2}h[/tex]
Thus, multiplying the volume of the right circular cone by 3 would give us the volume of the right circular cylinder.
[tex] V = \frac {1}{3} \pi r^{2}h * 3[/tex]
Substituting into the equation, we have;
[tex] V = 300 * 3[/tex]
V = 900in³
Therefore, the volume of a right cylinder that has the same base and height as the cone is 900 cubic inches.

Answer no 16 and 17
9514 1404 393
Eexplanation:
16. Suppose the roots are α and kα. Then we can write the equation as ...
a(x -α)(x -kα) = 0
ax² -ax(α +kα) +akα² = 0
Comparing to the original equation, we can equate coefficients to get ...
b = -aα(1+k)c = akα²Solving the first for α gives ...
α = -b/(a(1+k)
Substituting into the second, we have ...
c = ak(-b/(a(1+k)))²
Multiplying by a(1+k)², we get ...
(1+k)²ac = kb²
Using k=2 gives ...
9ac = 2b² . . . . . as required
__
17. Using the previous result with k=1 (equal roots), we have ...
(1+k)²ac = kb²
4ac = b² . . . . . for k=1
______
Additional comment
We observed that the problems were similar, but had different factors relating the roots. So, we elected to solve the general case, then fill in the specific values for the two problems.

General Formulas and Concepts:
Pre-Alg
Order of Operations: BPEMDASAlgebra I
Composition of functionsStep-by-step explanation:
Step 1: Define
f(x) = 3x - 4
g(x) = -2x + 7
(f o g)(5) is f(g(5))
Step 2: Find composite function
Substitute: (f o g)(x) = 3(-2x + 7) - 4Distribute: (f o g)(x) = -6x + 21 - 4Combine like terms: (f o g)(x) = -6x + 17Step 3: Solve

Answer:
2.31 ×10 ^− 2
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
A construction company charges $15 per hour for demolition Plus a one time $50 fee for the use of trash dumpsters how much would it cost for a full eight hours a day
Answer:
$170
Step-by-step explanation:
Given that:
One time fee for the use of trash dumpsters = $50
Charges for demolition per hour = $15
Time period for which trash dumpsters are used per day = 8 hours
To find:
The cost of 8 hours of operation = ?
Solution:
Here, to find the required cost, we need to first multiply the number of hours with the per hour cost of using the trash dumpsters.
And then we need to add the fixed / one time cost of the trash dumpsters to find the required cost.
Cost for using it for 8 hours = [tex]8 \times 15 = \$120[/tex]
Total cost for using it for full 8 hours = Cost for using it for 8 hours + One time cost = $120 + $50 = $170
Therefore, the answer is: $170

What is the quadruple of 2-2
Answer:
Please check the explanation below.
Step-by-step explanation:
As we know that quadruple is basically a fourfold amount or number.
For example,
The quadruple of 6 is 24.
4 x 6 = 24
Similarly, the quadruple of 10 is 40.
4 x 10 = 40
Now, let me solve your query.
Given the expression
2 - 2
as
2-2 = 0
so
we have to determine the quadruple of 0.
i.e.
4 x 0 = 0
Therefore, 0 is the quadruple of 2-2 (or 0).
I hope, it has cleared your concept.
Calculate the value of x
Answer:
12x=180 -30
x= 150/12
x= 12.5°
Answer:
x = 12.5
Step-by-step explanation:
The 3 angles lie on a straight line and so sum to 180°, that is
x + 10 + 10x + x + 20 = 180, simplify
12x + 30 = 180 ( subtract 30 from both sides )
12x = 150 ( divide both sides by 12 )
x = 12.5

Rewrite each linear equation in standard form. Then, state the values for A, B, and C.
0.09x-0.01y=0.39 _____
A=_______,B= _______,C= _______
Answer:
A = 9/100
B = -[1/100]
C = -[39/100]
Step-by-step explanation:
Given:
0.09x - 0.01y = 0.39
Find:
A,B,C
Computation:
Linear equation;
Ax + By + C = 0
So,
0.09x - 0.01y = 0.39
9x/100 - 1y/100 = 39/100
9x/100 - 1y/100 - 39/100= 0
So,
A = 9/100
B = -[1/100]
C = -[39/100]
The concurrency of which lines create the Centroid?
A. Perpendicular Bisectors B. Medians
C. Angle Bisectors
D. Altitudes
