The price of a public metro ride rose from $2 to $2.50. If you graphed thefunction f(x) = the cost of x metro rides, how would the graph changeafter the fare rose?
when would you solve by elimination?
Answer:
when its a linear equation
Step-by-step explanation:
Answer:
In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.
(2x-7)(5x+75)=0
Solve this using factoring, what are the two x’s?
Note : a × b = 0 ==》 a = 0 Or b = 0
_________________________________
( 2x - 7 )( 5x + 75 ) = 0
2x - 7 = 0 ===》 2x = 7 ===》 x = 7 / 2
===》 x = 3.5
Or
5x + 75 = 0 ==》 5x = - 75 ==》 x = - 75 / 5
==》x = - 15
Step-by-step explanation:
(2x-7)(5x+75)=0
2x(5x+75) -7 (5x+75)=0
10x^2 + 150x - 35x - 525 =0
10x^2 + 115x - 525 =0
5(2x^2 + 23x - 105 ) =0
2x^2 +30x-7x - 105 =0
2x ( x + 15 ) -7 ( x + 15) = 0
(2x-7) (x + 15) =0
so, 2x-7=0 and x+15 =0
x = 7/2 and x = -15

x+10=2x-4 what does x=
Answer:
x = 14
Step-by-step explanation:
x + 10 = 2x - 4
x + 10 - 10 = 2x - 4 - 10
x = 2x - 14
x - 2x = 2x - 2x - 14
- x = - 14
- x ÷ - 1 = - 14 ÷ - 1

You have total coins for a total of $. . You only have quarters and dimes. Let represent the number of quarters and represent the number of dimes.
Answer:
[tex]Quarters = 41[/tex]
[tex]Dimes = 18[/tex]
Step-by-step explanation:
Given
[tex]Coins = 59[/tex]
[tex]Worth = \$12.05[/tex]
[tex]d = dimes[/tex]
[tex]q = quarters[/tex]
Required
The number of each coin
The total coins can be represented as:
[tex]d + q = 59[/tex]
[tex]1\ quarter = \$0.25 \\ 1\ dime = \$0.10[/tex]
So, the worth of the coin is:
[tex]0.25q + 0.10d = 12.05[/tex]
The equations to solve are:
[tex]0.25q + 0.10d = 12.05[/tex]
[tex]d + q = 59[/tex]
Make d the subject in: [tex]d + q = 59[/tex]
[tex]d =59 - q[/tex]
Substitute [tex]d =59 - q[/tex] in [tex]0.25q + 0.10d = 12.05[/tex]
[tex]0.25q + 0.10(59 - q) = 12.05[/tex]
[tex]0.25q + 5.9 - 0.10q = 12.05[/tex]
Collect like terms
[tex]0.25q - 0.10q = 12.05 - 5.9[/tex]
[tex]0.15q = 6.15[/tex]
Solve for q
[tex]q=\frac{6.15}{0.15}[/tex]
[tex]q=41[/tex]
Substitute [tex]q=41[/tex] in [tex]d =59 - q[/tex]
[tex]d = 59 - 41[/tex]
[tex]d = 18[/tex]
So:
[tex]Quarters = 41[/tex]
[tex]Dimes = 18[/tex]

Answer:
4W = 25
Step-by-step explanation:
The hanger is balanced, so each side must have the same quantity.
There are 4W on one side and 25 on the other. That means that 4W and 25 must equal each other in order to keep the hanger balanced.
Answer:
We can see on one side there is 4 w's and on the other side is a 25, because the hanger is balanced these must be equal:
We can form the equation:
4w = 25
w = 6.25

Answer: x = 13.4
Step-by-step explanation:
1. Subtract 90 degrees and 33 degrees to get angle X, which is 57 degrees.
2. Using Laws of Sine, plug in the known elements of the triangle:
(16) / (sin(90)) = (x) / (sin(57))
3. Cross multiply, this will leave 16sin(57) = xsin(90)
4. Divide sin(90) to the other side, leaving x = (16sin(57)) / (sin(90))
5. Plug this into a calculator and your final answer should be 13.4

Answer:
____1260 ____Since we have to predict, we can use ratios to help us solve this.
12 said yes out of 72 randomly chosen, SO,
if 210 would say yes (goes to play), how many is total??
12 is to 72 AS 210 is to HOW MUCH (let it be x)??
We can setup ratio, cross multiply, and solve for x:
= 12/72= 210/x
= 12x = 210*72
=12x = 15,120
=x = 15,120/12
=x =1260What is the answer to my question.

Use one of the triangles to approximate PQ in the triangle below.
Choose 1 answer:
(Choice A)
4.5 units
(Choice B)
5.4 units
(Choice C)
9.1 units
(Choice D)
10.9 units
Answer:
The answer is B 5.4 units
Step-by-step explanation:
The approximate value of PQ in the right angle triangle is 5.4 units.
Right angle triangleA right angle triangle has one of its angles as 90 degrees. Therefore, the sides can be found by trigonometric ratios.
Hence,
sin 50 = opposite / hypotenuse
sin 50 = PQ / 7
cross multiply
PQ = 7 sin 50°
PQ = 7 × 0.76604444311
PQ = 5.36231110183
PQ = 5.4 units

He price of a computer component at the QRCC bookstore is decreasing at a rate of 2.25% per year. Decide whether this decrease is linear or exponential.
Answer:
The decrease is exponential.
Step-by-step explanation:
An exponential decrease is something like:
f(x) = A*(r)^x with 0 < r < 1
A linear decrease is something like:
g(x) = -a*x + b with a > 0
First ai general formula.
If you have a quantity Q, decreased by an X%, the new quantity will be:
New Quantity = Q - Q*(X%/100%)
Now let's look at the question:
Suppose that the original price of the computer component is K
And the price as a function of the year is P(y)
Then we know that, in the year zero, the price is K.
P(0) = K
One year after, the price decreases by 2.25%
Then:
P(1) = K - K*(2.25%/100%) = K*(1 - 0.0225)
After another year, we will have another decrease of 2.25%
Then:
P(2) = K*(1 - 0.0225) - K*(1 - 0.0225)*(2.25%/100%)
P(2) = K*(1 - 0.0225)*(1 - 0.0225) = K*(1 - 0.0225)^2
We already can see the pattern, we can expect that in the year y, the price of the component will be:
P(y) = K*(1 - 0.0225)^y
This clearly is an exponential decrease.

From the matrix addition, we can write as,
-2x + 3 = x
Now,
Combining the like terms.
-2x - x + 3 = 0
-3x = -3
Dividing 3 into both sides.
-x = -1
x = 1
Thus,
The value of x in the matrix is 1.
