Answer:
27
Step-by-step explanation:
Solve for y:
5 y = 135
Divide both sides of 5 y = 135 by 5:
(5 y)/5 = 135/5
5/5 = 1:
y = 135/5
The gcd of 135 and 5 is 5, so 135/5 = (5×27)/(5×1) = 5/5×27 = 27:
Answer: y = 27
Answer:
y = 27
Step-by-step explanation:
Divide both sides of the equation by 5.
[tex]\frac{5y}{5}[/tex] = [tex]\frac{135}{5}[/tex]
[tex]y = 27[/tex]
To check if this is true, substitute 27 back into the original equation.
[tex]5y=135[/tex]
[tex]5(27)=135[/tex]
[tex]135=135[/tex]
The inverse of y = 2x + 2 is
Answer:
The inverse of given function is [tex]y=\frac{1}{2}x-1[/tex].
Step-by-step explanation:
The given function is
[tex]y=2x+2[/tex]
The step and shown below to find the inverse of the function.
Step 1: Interchange x and y.
[tex]x=2y+2[/tex]
Step 2: Isolate variable y.
[tex]x-2=2y[/tex]

[tex]\frac{1}{2}(x)+\frac{1}{2}(-2)=y[/tex]
[tex]\frac{1}{2}(x)-1=y[/tex]
Therefore the inverse of given function is [tex]y=\frac{1}{2}x-1[/tex].
Answer:
The inverse of y = 2x+2 is 1/2x-1.
Step-by-step explanation:
Given equation is
y = 2x+2
let y = f(x) = 2x+2
We have to find the inverse of given function.
Adding -2 to both sides of given equation,we get
y-2 = 2x+2-2
y-2 = 2x
dividing by 2 to both sides of above equation , we have
(y-2) / 2 = 2x / 2
y/2 - 1 = x
Swapping equation, we have
x = y/2-1
put x = f⁻¹(y) in above equation ,we have
f⁻¹(y) = y/2 -1
Replace y with x , we have
f⁻¹(x) = x/2-1
Hence , the inverse of given function is 1/2x-1.
When you own a pet, there are one-time costs, such as a leash, and continuing costs, such as food. Suppose the one-time costs for owning a small dog are $180, and the continuing costs are $400 per year Which function models the average annual cost of owning a small dog for x years?
Answer:
Average cost per year = 400 + 180/x
Step-by-step explanation:
Using the formula y=mx+b
We know that b is the y intercept or initial value. That would be the start up costs
m is the slope on costs each time x increases, that would be 400 per year
Costs = 400x + 180
To find the average cost per year, we need to divide by x
Average cost per year = (400x + 180)/x
= 400 + 180/x
Answer:
answer to this question is f(x) = (180 + 400x)/x

Gina looks at the architectural plan of a four-walled room in which the walls meet each other at right angles. The length of one wall in the plan is 17 inches. The length of the diagonal of the floor of the room in the plan is approximately 18.79 inches. Is the room in the shape of a square? Explain how you determined your answer. Show all your work.
Final answer:
The room is not a square, as shown by applying the Pythagorean theorem, because the calculated diagonal of a square with 17-inch sides would be approximately 24.04 inches, not 18.79 inches.
Explanation:
To determine if the room is in the shape of a square, we can use the Pythagorean theorem, which relates the lengths of the sides of a right-angled triangle. For a square, the lengths of all four sides are equal. Therefore, if we assume that the length and the width of the room are both equal to the given wall length of 17 inches, the diagonal (d) of the square can be calculated using the Pythagorean theorem:
c2 = a2 + b2
where c is the length of the diagonal, and a and b are the lengths of the sides of the square.
So, it would be:
c2 = 172 + 172
= 289 + 289
= 578
Now we find the square root of 578 to find the length of the diagonal (c):
c ≈ √578 ≈ 24.04 inches
Since the given diagonal length is approximately 18.79 inches, and our calculated value for the diagonal of a square with sides 17 inches is approximately 24.04 inches, the room is not a square. The diagonal is too short for the room to be a square given the 17-inch wall.

The temperature today is 7 degrees celsius. Yesterday it was 13 degrees celsius cooler. What was the temperature yesterday?
Answer:
The temperature yesterday was -6 because 7-13 is -6.
Step-by-step explanation:
Answer:
The yesterday’s temperature is 6°C below the zero degree Celsius or (-6) degree Celsius.
Step-by-step explanation:
The temperature today is 7 degrees Celsius. Yesterday was 13 degrees Celsius cooler. That the temperature is colder means that the temperature was lower than today's temperature. This means that to obtain the temperature on the previous day, 13°C must be subtracted from today's temperature.
yesterday’s temperature=today’s temperature-13°C
It is now possible to replace today's temperature with 7 ° C
yesterday’s temperature=7°C-13°C
Remember that to subtract two integers of a different sign (one positive and the other negative), as in this case, you must subtract their absolute values (that is, subtract 13-7 = 6), and the answer will have the same sign as the number with the highest absolute value (absolute value or module of any real number is the same number but with a positive sign). As in absolute value 13 is greater than 7, the answer to the subtraction will be negative
yesterday’s temperature=7°C-13°C
So, finally, the yesterday’s temperature is 6°C below the zero degree Celsius or (-6) degree Celsius.

Plz answer
Final answer:
The multiplication of (3.4x10²) and (2x10³) results in 6.8x10⁵ after multiplying the coefficients and adding the exponents. Therefore, the correct answer is option (B).
Explanation:
Considering, the question it has asked to solve the following arithmetic operation in scientific notation: (3.4x10²)x(2x10³).
To solve this the following steps can be used :
we multiply the coefficients (3.4 and 2) and then add the exponents (2 and 3).
Multiplication of coefficients: 3.4 * 2 = 6.8
Addition of exponents: 2 + 3 = 5
Combining both parts: 6.8 x 10^5
The correct answer in scientific notation is therefore 6.8x10⁵, which corresponds with option B.

Step-by-step explanation:
A computer is normally $550 but is discounted to $385 which precent of the original price does mark pay
Answer:
70%
Step-by-step explanation:
We assume, that the number 550 is 100% - because it's the output value of the task.
We assume, that x is the value we are looking for.
If 100% equals 550, so we can write it down as 100%=550.
We know, that x% equals 385 of the output value, so we can write it down as x%=385.
Now we have two simple equations:
1) 100%=550
2) x%=385
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=550/385
Now we just have to solve the simple equation, and we will get the solution we are looking for.
Solution for 385 is what percent of 550
100%/x%=550/385
(100/x)*x=(550/385)*x - we multiply both sides of the equation by x
100=1.4285714285714*x - we divide both sides of the equation by (1.4285714285714) to get x
100/1.4285714285714=x
70=x
x=70

A function f(x) is graphed.
What is the slope of the function? M= 1,2,3,4
What is the y-intercept of the function? B= -2,-1,1,2
Which equation represents the graph of the function y=-x+2 , y=x+2 , y=2x+1 , y=-2x+1
Answer:
Point-Slope form: The equation of line is given by:
[tex]y-y_1=m(x-x_1)[/tex] ......[1]
where m is the slope and [tex](x_1,y_1)[/tex] is the point on the line.
From the given graph:
Consider two points i.e,
[tex](0, 1)[/tex] and (-0.5, 0)
Calculate slope:
Formula for slope is given by;
[tex]\text{Slope}(m) = \frac{y_2-y_1}{x_2-x_1}[/tex]
Substitute the given values we have;
[tex]m = \frac{0-1}{-0.5-0} = \frac{-1}{-0.5} = \frac{10}{5} =2[/tex]
Now, substitute the value of m = 2 and (0, 1) in equation [1] we have;
[tex]y-1 = 2(x-0)[/tex]
y-1 = 2x
Add 1 to both sides we get;
y = 2x+1
On comparing equation y = 2x+1 with the slope intercept form of a line (i.e, y = mx+b) then we have;
slope(m) = 2
y-intercept(b) = 1
therefore, the slope of the function:
m = 2
y-intercept(b) = 1
and the equation represents the graph: y = 2x+1
Answer:
2

Compute the amount of interest earned in the following simple interest problem. A deposit of 1,295 at 7% for 180 days=____. (note: use 365 days in a year
The interest earned is approximately $50.06.
To calculate the amount of interest earned in a simple interest problem, we can use the formula:
[tex]\[ \text{Interest} = \text{Principal} \times \text{Rate} \times \frac{\text{Time}}{\text{Total days in a year}} \][/tex]
Given:
- Principal (P) = $1,295
- Rate (R) = 7% or 0.07
- Time (T) = 180 days
- Total days in a year = 365 days
Plugging these values into the formula:
[tex]\[ \text{Interest} = 1295 \times 0.07 \times \frac{180}{365} \]\[ \text{Interest} = 1295 \times 0.07 \times \frac{180}{365} \]\[ \text{Interest} \approx 1295 \times 0.07 \times 0.493150685 \]\[ \text{Interest} \approx 50.05958904 \][/tex]

-2⁄3 a − 6 = 12
a =
Answer:
a = -27
Step-by-step explanation:
-2⁄3 a − 6 = 12
add 6 to both sides:-
-2/3 a -6 + 6 = 12 + 6
-2/3 a = 18
Now multiply each side by -3/2:-
a = 18 * -3/2 = -54/2
= -27
To solve the equation -2⁄3 a - 6 = 12 for 'a', add 6 to both sides of the equation and then multiply both sides of the equation by -3/2 to isolate the variable 'a'. The value of 'a' that satisfies the equation is a = -27.
Explanation:To solve the equation -2⁄3 a - 6 = 12 for 'a', we can start by isolating the variable on one side of the equation. First, let's add 6 to both sides of the equation:
-2⁄3 a - 6 + 6 = 12 + 6
-2⁄3 a = 18
Next, we can multiply both sides of the equation by -3/2 to get:
(-3/2)(-2/3 a) = (-3/2)(18)
a = -27
The value of 'a' that satisfies the equation -2⁄3 a - 6 = 12 is a = -27.
