Answer:
$189 - $315 - $7x
Step-by-step explanation:
Given the following :
Amount in Mae's account = $189
Each month balance is below $750;
Amount charged = $7
She withdrew $315 from her account and makes no deposit or withdrawal for the next x months
Her balance :
Initial amount = $189
Withdrawal made = $315
Amount charged when balance falls below $750 = fee * number of months = 7 * x = 7x
Hence, her balance after x months will be :
$189 - $315 - $7x
The balance of Mae expressed algebraically will be 189 - 315 - 7x.
The following can be deduced from the question:
Amount in Mae's account = $189Each month balance is below $750Amount charged = $7Therefore, the amount that is left in her account balance will be:
= 189 - 315 - (7 × x)
= 189 - 315 - 7x

Given a circle with endpoints of a diameter at –10 – 1i and 6 + 11i, answer the questions below. 1. The center of the circle is at ---+ --- i.
The center of the circle is at -2 + 5i.
What are Complex Number?Complex Numbers. Complex numbers are those that are expressed as a+ib, where a and b are actual numbers and I is a fictitious number called a "iota."
Complex numbers are numbers that consist of two parts — a real number and an imaginary number.
Given:
Diameter = –10 – 1 i = (- 10, - 1)
6 + 11 i = (6, 11)
Given that we are aware that these are the diameter's endpoints, it follows that the circle's center is the place that lies midway between the endpoints.
Then,
x = (-10 + 6) / 2
= - 4 / 2
= -2
y = (- 1 + 11) / 2
= 10 / 2
= 5
Hence, the center is located at (- 2, 5).

−8y−13=14y+11 what is the answer?
Answer:
y = -12/11
Step-by-step explanation:
-8y - 13 = 14y + 11
-8y - 14y = 11 + 13
-22y = 24
y = 24/-22
y = -12/11
Check:
-8*-12/11 - 13 = 14*-12/11 + 11
96/11 - 13 = -168/11 + 11
96/11 - 143/11 = -168/11 + 121/11 = -47/11
Which equation does the graph below represent?
y = 1 x
y = 4x
y = _ 1x
y = -4x
Answer:
Y=-4x
Step-by-step explanation:
Whenever you solve for slope, and the slope is 1, never write 1 in the equation. Write either -x or x. Let's take two coordinates, one which is (0, 0), which is the origin, and (1, -4). To find the slope, we insert the first coordinate and second coordinate values into the equation (Y2-Y1)/(X2-X1). We can insert these coordinates to get (-4 - 0)/(1 - 0), which simplifies to (-4)/1, which further simplifies to -4. Since the Y-intercept is zero, there is no value of B in the equation, which leaves the equation as Y=-4x
Jerry bought a coat on sale for 30% off. The sale price for the coat was $63, what is the regular price for the coat?
Answer:
The original regular price for the coat is $90
Step-by-step explanation:
The given information in the question are;
The percentage that was off (removed) from the sale price = 30%
The sale price at which Jerry bought the coat = $63
Whereby the regular price = P, we have;
P - 30% of P = $63
P - 0.3×P = $63
P×(1 - 0.3) = $63
0.7·P = $63
P = $63/0.7 = $90
Therefore, the regular (original) price for the coat = $90
The coat regular price at which the coat is displayed is at $90.
what is the absolute value of 2.3
The absolute value of any positive number is that number itself.
If you take the absolute value of a negative number, then just erase the negative sign and you have your answer.
The absolute value is never negative. It represents distance from that value to 0 on the number line.
So saying |2.3| = 2.3 means the number 2.3 is exactly 2.3 units away from 0 on the number line.
Another example would be |-7| = 7 showing that from 0 to -7 is 7 spaces.
The required absolute number of 2.3 is also 2.3.
GIven that,
An absolute number of the value 2.3 is to be determined.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
The absolute number is defined as the outcome of the modulus function is called the absolute number or all natural numbers are examples of absolute numbers.
Here,
For the absolute value,
f(x) = |x|
f(2.3) = |2.3|
(since |x| = x or | -x | = x )
f( 2.3 ) = 2.3
Thus, the required absolute number of the value 2.3 is 2.3 itself.

step 2. reduce is 7.07
step 3. round 7.07 so you only have one digit after the decimal point to get the answer., 7.1
Answer:
7
Step-by-step explanation:
Consider perfect squares either side of 50, that is
49 < 50 < 64, thus
[tex]\sqrt{49}[/tex] < [tex]\sqrt{50}[/tex] < [tex]\sqrt{64}[/tex] , that is
7 < [tex]\sqrt{50}[/tex] < 8
Since 50 is nearer to 49 than it is to 64, then

A rectangle has an area of 4x2 +19x + 12 and a length of (x + 4). What is the width?
The width of the rectangle with an area x² = 19x + 12 is (4x + 3).
What are the area and perimeter of a rectangle?The area of a rectangle is the product of its length and width.
The perimeter of a rectangle is the sum of the lengths of all the sides.
We know the area of a rectangle is (length×widh).
Given, A rectangle has an area of 4x² + 19x + 12 and a length of (x + 4).
∴ width of the rectangle is = (4x² + 19x + 12)/(x + 4).
Or, we know that the product of two linear equations is a quadratic so,
4x² + 19x + 12.
4x² + 16x + 3x + 12.
4x(x + 4) + 3(x + 4).
(x + 4)(4x + 3).
So, the width of the rectangle is (4x + 3).

this group of objects?
Given :
Two hockey of same mass.
One is travelling at a speed of 2 m/s.
Other is in rest or 0 m/s.
To Find :
The momentum of this group of objects.
Solution :
Since , no external force is applied , so momentum will remains same :
Momentum of group of objects ,
[tex]M = mv_1^2+mv_2^2\\\\M = 0.25\times 2^2+0.25\times 0\\\\M=1 \ kg \ m/s[/tex]
Therefore , momentum of the system is 1 kg m/s.
Hence , this is the required solution.

A store employee creates a display of sleds priced at $40 apiece. The store paid $32 for each sled. What is the mark-up percentage
Answer:
Mark-up percentage is 25%.
Step-by-step explanation:
From the question, the store bought each sled at $32 which is the cost price. The sled was display for sale at $40 apiece.
Mark-up percentage = [tex]\frac{selling price - cost price}{cost price}[/tex] x 100%
But,
selling price - cost price = $40 - $32
= $8
So that,
Mark-up percentage = [tex]\frac{8}{32}[/tex] x 100%
= 0.25 x 100%
= 25%
Therefore, the mark-up percentage is 25%.
