Step-by-step explanation:
Pierre had $42 before he paid his club dues. Evaluate the expression 42 − d for d = 25 to find how much money Pierre had left after he spent $25 on dues
Answer:Pierre has $17 left
Step-by-step explanation:
Amount of money before dues = $42
according to the expression 42-d, d represents dues= $25
Amount left = Amount of money before dues - Amount of dues
= $42- $25
=$17
Pierre has $17 left after he spent $25 on dues.

40 = 2f + 12
f
f
40
12
Answer:
i don't know what the hangers are for but the calculation is given below
Step-by-step explanation:
40 = 2f + 12
40 - 12 = 2f
28 = 2f
28/2 = f
14 = f
therefore f = 14

Raj plotted point L in the coordinate plane below. On a coordinate plane, point L is 1.5 units to the left and 4 units up. He says that the plotted point is (4, negative 1.5). What is Raj's error? The x-coordinate should be -4. The y-coordinate should be 1.5. The x- and y-coordinates are switched. Both coordinates should be positive.
Answer:
The x- and y-coordinates are switched.
Step-by-step explanation:
Given that:
Point L plotted by Raj is in a coordinate plane.
Point L is 1.5 units to the left and is 4 units up.
As per Raj, the point is (4, -1.5).
Kindly refer to the general coordinate plane diagram in the answer area.
The origin is at (0,0) which is our reference point for plotting any point.
When we move left on the coordinate plane from origin, the [tex]x[/tex] coordinate will decrease i.e. will become negative.
When we move right on the coordinate plane from origin, the [tex]x[/tex] coordinate will increase i.e. will become positive.
When we move down on the coordinate plane from origin, the [tex]y[/tex] coordinate will decrease i.e. will become negative.
When we move up on the coordinate plane from origin, the [tex]y[/tex] coordinate will increase i.e. will become positive.
Now, as per question statement, 1.5 units to the left.
i.e. [tex]x[/tex] = -1.5
4 units up.
i.e. [tex]y[/tex] = 4
Therefore, the point will be (-1.5, 4).
So, the answer is:
The x- and y-coordinates are switched.
Answer:
-x -y changed

Answer:
(y − 9) (y − 2)
Step-by-step explanation:
Factor y^2 − 11y + 18 using the AC method.
(y − 9) (y − 2)
The “AC” method or factoring by grouping is a technique used to factor trinomials. A trinomial is a mathematical expression that consists of three terms.
4/-2 flipped over the x axis
Answer:
I suppose that here we have:
"(4, - 2) flipped over the x-axis"
Regardless of that, i will answer this in a kind of general way.
When we have a point (x, y) and we do a reflection over the x-axis (or the line y = 0, is the same) the reflected point will be (x, - y)
If we instead had a reflection over the y-axis (or the line x = 0) the reflected point will be (-x, y)
Then if we have the point (4, -2) and we have a reflection over the x-axis, the sign of the y-component needs to change.
Then the reflected point will be (4, -(-2)) = (4, 2)

Answer:
The Y intercept is (0,7)
Step-by-step explanation:
If it is a y intercept, there will be a number in the y coordinate. For example, (x,y) if the point said (7,0) that would be the x intercept. Because it it (0,7) and in the y place that makes it a y intercept. I hope this helped :)
The perimeter of a parallelogram is 88 cm and one of its adjacent sides is longer
than the other by 10 cm. Find the length of each of its sides.
Answer:
sides are 17 cm and 27 cm
Step-by-step explanation:
let the side be x then the adjacent side is x + 10
The perimeter is then
x + x + x + 10 + x + 10 = 88, that is
4x + 20 = 88 ( subtract 20 from both sides )
4x = 68 ( divide both sides by 4 )
x = 17
and x + 10 = 17 + 10 = 27
The sides of the parallelogram are 17 cm and 27 cm
2. Solve the equation for x.
14 - x = 5x - 4
Answer:
x=3
Step-by-step explanation:
14-x=5x-4
Add the x from the left side to the right
14=6x-4
and the 4 to the left side
16=6x
6x=18
x=3
Answer:
x = 3
Step-by-step explanation:
If we substitute x for 3 it will give u the following expression:
14 - 3 = 5 x 3 - 4
If we solve both these expressions they will both give us: 11
This will prove the equation correct

log(4m-10)=1
Answer:
m=5
Step-by-step explanation:
1. Convert the logarithm into exponential form using the fact that [tex]log_{a}[/tex](x)=b is equal to x=[tex]a^{b}[/tex] so ... 4m-10=[tex]10^{1}[/tex]
2. Any expression raised to the power of 1 equals itself so ... 4m-10=10
3. Move the constant to the right-hand side and change its sign so ... 4m=10+10
4. Add the numbers so ... 4m=20
5. Divide both sides of the equation by 4 so ... m=5, m>[tex]\frac{5}{2}[/tex]
6. Check if the solution is in the defined range so ... m=5

Mortgage loan of $84,000.
Interest rate is 6 percent.
Monthly payment is $504.
How much of the first monthly payment is for interest?
Answer: $420
Step-by-step explanation:
The monthly payment has both an interest component and a principal repayment component.
The interest component is based on the total loan amount(principal) still due at the time and the principal repayment component will be the rest of the payment.
First convert the interest rate to a monthly interest rate as the payments are done monthly:
= 6%/12
= 0.5%
Interest = Principal remaining * interest rate
= 84,000 * 0.5%
= $420
Answer:
420

Answer:
x = 1z = 11Step-by-step explanation:
If we assume that the segment marked (2x+1) is a midsegment, then it is half the length of the parallel base:
2(2x+1) = 8x-2
4x +2 = 8x -2 . . . . eliminate parentheses
4 = 4x . . . . . . . . . . add 2-4x to both sides
1 = x . . . . . . . divide by 4
__
The above assumption makes the two segments marked with z-expressions be the same length:
3z = z +22
2z = 22 . . . . . . subtract z
z = 11 . . . . . . . . . divide by 2
The values of X and Z are 1 and 11, respectively.
