y = 6x + 11
2х - Зу = 7
9514 1404 393
Answer:
(x, y) = (-2.5, -4)
Step-by-step explanation:
Since you are given an expression for y, it is convenient to substitute that into the second equation.
2x -3(6x +11) = 7
2x -18x -33 = 7
-16x = 40 . . . . . . add 33
x = -40/16 = -2.5
Using the equation for y, we find ...
y = 6(-2.5) +11 = -15 +11 = -4
The solution is (x, y) = (-2.5, -4).
8) Find x and y.

Hat is \text{P(heads})P(heads)start text, P, left parenthesis, h, e, a, d, s, end text, right parenthesis? If necessary, round your answer to 222 decimal places.
Question:
You flip a fair coin ; What is P(heads)? If necessary, round your answer to 2 decimal places
Answer:
[tex]P(Head) =0.50[/tex]
Step-by-step explanation:
Given:
A fair coin
Required
Determine [tex]P(Head)[/tex]
A coin has two faces (Head (1) and Tail (1) )
i.e. 1 head and 1 tail
Both of which have equal probability, which is calculated as follows:
[tex]P(Head) = P(Tail) = \frac{1}{1 + 1}[/tex]
[tex]P(Head) = P(Tail) = \frac{1}{2}[/tex]
[tex]P(Head) = P(Tail) = 0.5[/tex]
Hence:
[tex]P(Head) =0.50[/tex]
Answer: Its 0.50

Answer:
a.
Step-by-step explanation:
(2, 10) and (4, 10) have the same y value so it's not a function etc. etc.
Answer:
D. The relation represents y as a function of x, because each value of x is associated with a single value of y
Step-by-step explanation:
As long as no one x-value has two solutions, it can be considered a function. The x-values are {0, 2, 4, 6, 8}. Since there isn't any repetition, this can be considered as a function. The fact that 10 is repeated in the y-values doesn't affect that it is a function.

Trudy bought a $20 prepaid long distance phone card. for every minute that she talks, $0.25 is deducted from her card. The function f(m)=20-0.25m represents the amount of money f(m) she has left after talking m minutes.FInd the zero and explain what it means in the context of the situation.
Answer:
Step-by-step explanation:
Given the function f(m)=20-0.25m to represent the amount of money f(m) she has left after talking m minutes, the zero of the equation can be gotten by setting f(m) to 0
f(m)=20-0.25m
0 =20-0.25m
-20 = -0.25m
m = -20/-0.25
m = 80
Hence Trudy will have talked for 80minutes if she has no money left

[tex] - \frac{1}{2} {n}^{2} + 18 = 0 \\ [/tex]
Subtract sides 18
[tex] - \frac{1}{2} {n}^{2} + 18 - 18 = - 18 \\ [/tex]
[tex] - \frac{1}{2} {n}^{2} = - 18 \\ [/tex]
Negatives simplifies
[tex] \frac{1}{2} {n}^{2} = 18 \\ [/tex]
Multiply sides by 2
[tex]2 \times \frac{1}{2} {n}^{2} = 2 \times 18 \\ [/tex]
[tex] {n}^{2} = 36[/tex]
Take √ of the sides

Simba he's looking for a financial institution to give him a loan for a new house. Which of these institutions would be LEAST likely to provide the service.
Hi, you've asked an incomplete question that lacks the options. However, I answered from a general perspective.
Explanation:
Remember, the term financial institution (FI) often refers to any institution that deals with monetary transactions like loans, investments, currency exchange, or deposits.
For example, most specialized financial institutions not under the housing sector may refuse to provide such loans to Simba; such as An Agricultural financial institution, An Industrial financial institution, etc.

Answer:
$68.00
Step-by-step explanation:
Let s represent the opening price. Then the closing price is ...
s - 3.25% × s = $65.79
s(1 -0.0325) = $65.79 . . . . collect terms
0.9675s = $65.79 . . . . . . . simplify
s = $65.79/0.9675 . . . . . . .divide by the coefficient of s
s = $68.00 . . . . . the opening stock price

krytine has a weekend job advertising an upcoming play. she has two options for being paid. Option A is an hourly wage of $7.50 Option B is 5% commission on all money made at the play. she plans to work 7 hours each day on Saturday and Sunday. krystine estimates the play will make about $2,000 this weekend. Which option gives more earnings this weekend?
The Answer is: The hourly rate option of $112 is higher than the commission rate of $105.
Step-by-step explanation:
She will work 16 hours at $7.00 per hour:
16 * 7 = $112
Or she could take the 5% commission on $2,100:
2100 * .05 = $105.
The hourly rate is higher than the anticipated commission amount.
why did my dog have diarrhea when it ate a strawberry?
Answer: I don’t know, because strawberries are seen as good for dogs and it provides them with extra vitamin c. Maybe he/she just didn’t like it or it didn’t sit well in the stomach.
Answer: Sometimes a dog may be allergic to a certain food. Vomiting, diarrhea and skin problems may be symptoms of an allergic reaction. Consult your veterinarian if any of those occur. Introduce only one type of fruit at a time to your dog. Hope this helps... Stay safe and have a great weekend...

c. f (5) = 13 and f (-3) = -3
d. f (5) = 5 and f (-3) = -3
Answer:
C. f(5) = 13 and f(-3) = -3

Step 1: Define
f(x) = 2x + 3
x = 5
x = -3
Step 2: Evaluate
x = 5
Substitute: f(5) = 2(5) + 3Multiply: f(5) = 10 + 3Add: f(5) = 13x = -3
Substitute: f(-3) = 2(-3) + 3Multiply: f(-3) = -6 + 3Add: f(-3) = -3We evaluate Separately.
Let x = 5
f(5) = 2(5) + 3
f(5) = 10 + 3
f(5) = 13
Now let x = -3.
f(-3) = 2(-3) + 3
f(-3) = -6 + 3
f(-3) = -3

Evelyn drove 248 miles in 8 hours, If she continued at the same rate, how far would she travel in 6 hours?
Answer:
Continuing at the same rate, Evelyn would travel 186 miles.
Step-by-step explanation:
8/248 6/x. then cross multiply 8*x 248*6 = 8x = 1488 x = 186
Answer:
Evelyn will have driven 186 miles
Step-by-step explanation:
Step 1: 248 miles in 8 hours: Divide 248 by 8 in order to find how much miles she travels per hour. (248/8+31)
You should get 31 miles per 1hr.
Step 2: Multiply 31miles/hr by 6hrs in order to find the distance she travels. (31*6=186)
You should get 186 miles.

On a coordinate plane, two parabolas open up. The solid-line parabola, labeled f of x, goes through (negative 2, 4), has a vertex at (0, 0), and goes through (2, 4). The dashed-line parabola, labeled g of x, goes through (3, 6), has a vertex at (5, 2), and goes through (7, 6).
What is the equation of the translated function, g(x), if
f(x) = x2?
A: g(x) = (x + 5)2 + 2
B: g(x) = (x + 2)2 + 5
C: g(x) = (x – 2)2 + 5
D: g(x) = (x – 5)2 + 2
Answer:
D
Step-by-step explanation:
Option 4.
The vertex form of a parabola is
where, a is a constant (h,k) is the vertex.
The given function is
The vertex of the function is (0,0) and it goes through (-2, 4) and (2, 4).
It is given that the vertex of function g(x) is at (5,2).
Substitute h=5 and k=2 in the equation.
g(x) is passed through (3, 6).
Divide both sides by 4.
Substitute a=1 in equation (2).
The function g(x) is g(x) =(x-2)2+5) .
Therefore, the correct option is 4.
