What is the image of the point (-7, -3) after a rotation of 90° counterclockwise
about the origin?
The new point after rotation of point (-7, -3) counterclockwise by 90 degrees will be ( 3, -7).
What are coordinates?
A pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane. typically expressed by the x-value and y-value pairs (x,y).
Coordinates are always written in the form of small brackets the first term will be x and the second term will be y.
For example (5,3) here 5 will be for the x and 3 will be for the y.
Another example is (9,0) here 9 is for x and 0 is for y.
Given,
Point A = (-7, -3)
Let's say after rotation this point moves to a new coordinate (x, y) which is point B
Let's say the origin is O
Slope of line segment AO = (-3-0)/(-7-0) = 3/7
Slope of line segment BO = (y - 0)/(x - 0) = y/x
Now,
Since both lines are perpendicular to each other so
Slope AO × Slope BO = -1
3/7 × y/x = -1 ⇒ 3y = -7x
Now if we observe the result then it will be clear that if we put x = 3 than y = -7 will be the new coordinate.
Hence, The new point after rotation of point (-7, -3) counterclockwise by 90 degrees will be ( 3, -7).

Gabriel invested $77,000 in an account paying an interest rate of 3 1/2% compounded monthly. Isabella invested $77,000 in an account paying an interest rate of 4 1/8% compounded quarterly. After 6 years, how much more money would Isabella have in her account than Gabriel, to the nearest dollar?
WE know, compound interest is given by :
[tex]A = P(1 + \frac{r}{n})^{nt}[/tex]
Here, P is principle amount.
r is annual interest rate.
n, number of times that interest is compounded per unit t .
t, time the money is invested or borrowed for.
To Find :
How much more money would Isabella have in her account than Gabriel, to the nearest dollar.
Solution :
[tex]D = P(1 + \frac{r_1}{n})^{nt}- P(1 + \frac{r_2}{n})^{nt}\\\\D = 77000\times ( 1 + \dfrac{33}{8\times 12})^{12\times 6}-77000\times ( 1 + \dfrac{7}{2\times 12})^{12\times 6}\\\\D = \$(1.257\times 10^{14})[/tex]
Hence, this is the required solution.

4(2x - 1) = 3x + 6 Solve for x. Show steps with sentences supporting each step.
Answer:
x = 2
Step-by-step explanation:
4(2x - 1) = 3x + 6
Simplify
8x - 4 = 3x + 6
Subtract 3x from both sides
8x - 3x - 4 = 3x - 3x + 6
5x - 4 = 6
Add 4 to both sides
5x - 4 + 4 = 6 + 4
5x = 10
Divide both sides by 5
5x/5 = 10/5
x = 2
Step-by-step explanation:
4(2x - 1) = 3x + 6
8x-4=3x+6
8x-3x=6+4
5x=10
x=10/5=2

A race car travels 276 feet each second. How many yards does the race car travel in 5 seconds if it maintains that speed?
Answer:
460 yards
Step-by-step explanation:
3 feet are in a yard so 276 feet / 1 second * 1 yard / 3 feet=92 yards per second
92 * 5 = 460 yards
Unit rate is the quantity of an amount of something at a rate of one of another quantity.
If the car travels at a speed of 276 feet per second, the number of yards the race car travels in 5 seconds is 460 yards.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
Example:
A man can travel 3 miles in 60 minutes.
The man can travel 1 mile in 20 minutes.
We have,
A car travels 276 feet each second.
This can be written as:
276 feet = 1 second
Multiply both sides by 5 we get,
5 x 276 feet = 5 x 1 second
1380 feet = 5 second ____(1)
1 yard = 3 feet
Multiply both sides by 460.
460 x 1 yard = 460 x 3 feet
460 yard = 1380 feet ____(1)
From (1) and (2) we get,
460 yard = 5 seconds
Thus,
If the car travels at a speed of 276 feet per second, the number of yards the race car travels in 5 seconds is 460 yards.

Larry says 5 × 900 is less than 5 × 9,000. Doni says 5 × 900 is greater than 5 × 9,000. Which statements about the two products are correct? Choose all that apply.
Answer:
Larry's statement is correct
Step-by-step explanation:
Larry says 5 × 900 is less than 5 × 9,000.
Doni says 5 × 900 is greater than 5 × 9,000.
5 × 900 = 4500
5 × 9000 = 45,000
45,000 is greater than 4500 because the place value of 45,000 is tens thousands and 4500 is Thousands.
Hence, Larry's statement is correct.(Larry says 5 × 900 is less than 5 × 9,000.)

Square root of 32 units
8 units
Answer:
sq rt of 32 units
Step-by-step explanation:
use the pythagorean theorem:
4^2 + 4^2 = c^2
16 + 16 = c^2
32 = c^2
sq rt of 32 = c
The length of the hypotenuse of a right triangle is 4√2.
What is Pythagoras theorem?The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
Given:
P= 4 units, B= 4 units
Now, using Pythagoras theorem
H² = P² + B²
H² = 4² + 4²
H²= 16+ 16
H² =32
H= √32
H= 4√2
Hence, the Hypotenuse is 4√2.

Given :
The store sells gasoline for .25 per gallon below it's regular cost per gallon.
Suppose the store sells 5,750 gallons that day.
To Find :
the stores profit or loss in comparison to the amount the store would had made without the special offer.
Solution :
Since, store is selling gasoline for lower amount than regular so they will be in loss.
Loss =$ 0.25 × 5750
Loss = $1437.5
Therefore, loss of store in comparison to the amount the store would had made without the special offer is $1437.5 .
Hence, this is the required solution.

In this hanger, the weight of the triangle is x and the weight of the square is y. 1. Write an equation using x and y to represent the hanger. x + y = x + y 2. If x is 6, what is y?
Answer:
a. Equation is 3x - 2y = 0
b. x = 6 and y = 9
Step-by-step explanation:
a.
Given that
The Weight of the square is y
And, the weight of the triangle is x
Now the equation according to the attached diagram is
x + 3y = 4x + y
4x - x + 3y - y = 0
3x - 2y = 0
b.
Now if x = 6
So, y would be
3x - 2y = 0
3x = 2y
3(6) = 2y
18 = 2y
y = 9
We simply applied the above equation so that the correct value could come
