Using the multiplication and the subtraction property, we can prove that the value of y in the equation given is: 7. (see proof below).
How to Solve an Equation?Given the equation, y + 2/3 = 3, to prove that y = 7, we have to solve the given equation in other to find the value of y which must be equal to 7.
(y + 2)/3 = 3 [given]
3 × (y + 2)/3 = 3 × 3 [multiplication property of equality]
y + 2 = 9
y + 2 - 2 = 9 - 2 [subtraction property of equality]
y = 7
Thus, using the multiplication and the subtraction property, we can prove that the value of y in the equation given is: 7.

Mardi received an inheritance of $60,000. she investrf part at 11% and deposited the remainder in tax-free bonds at 12%. her total annual income from the investments was $6800. find the ammount invested at 11%.
When Mardi received an inheritance of $60000, she invested part at 11% and deposited the remainder in tax-free bonds at 12%, so she gets $6800as annual income then the amount invested at 11% is $20000
Given,
The total amount Mardi received = $60000
She invested part at 11% and deposited the remainder in tax-free bonds at 12%.
Annual income from the investment = $6800
Consider the part of money invested at 11% as x
Then the equation will become
(60000-x)0.11+0.12x =6800
6600-0.11x+0.12x =6800
0.01x+6600=6800
0.01x=200
x= $20000
Hence, when Mardi received an inheritance of $60000, she invested part at 11% and deposited the remainder in tax-free bonds at 12%, so she gets $6800 as annual income then the amount invested at 11% is $20000

A triangle with vertices at (-6, 5), (-5, 1), and (-8, 2) is reflected over the y-axis What are the coordinates of the vertices of the reflected image? Enter the correct answers in the boxes. Show Hints Preimage coordinates Image coordinates (-6,5) (-5,1) (-8,2) 03
Answers:
(6, 5)
(5, 1)
(8, 2)
==================================================
Explanation:
The rule we use is [tex](\text{x}, \text{y}) \to (-\text{x}, \text{y})[/tex] when reflecting over the vertical y axis.
The x coordinate flips from positive to negative, or vice versa. The y coordinate stays the same. So a point like (-6, 5) reflects over to (6, 5). The x coordinate -6 flipped to +6 or simply 6. The y coordinate stayed at 5.
Use this idea to reflect the other points.
find the volume of the parallelepiped with adjacent edges pq, pr, and ps. p(−2, 1, 0), q(4, 4, 4), r(1, 4, −1), s(3, 6, 1)
The volume of the parallelepiped with adjacent edges PQ, PR, and PS is 24 cubic units.
What is parallelepiped?Six parallelograms come together to form a three-dimensional shape called a parallelepiped (the term rhomboid is also sometimes used with this meaning). It is comparable to a parallelogram in the same way that a cube is comparable to a square. In Euclidean geometry, the four concepts—parallelepiped and cube in three dimensions, parallelogram, and square in two dimensions—are specified; however, only parallelograms and parallelepipeds exist in the setting of a more generic affine geometry, where angles are not discriminated.
There are three similar descriptions of a parallelepiped:
A polyhedron called a hexahedron, which has six parallelogram-shaped facesThree pairs of parallel faces on a hexahedron, andA prism with a parallelogram as its base.We have been that p(−2, 1, 0), q(4, 4, 4), r(1, 4, −1), and s(3, 6, 1) are the adjacent edges of parallelepiped
PQ = Q-P = <6,3,4>
PR = R-P = <3,3.-1>
PS= S-P = <5,5,1>
[ PQ PR PS] = [tex]\begin{vmatrix}6& 3 & 4 \\ 3& 3 &-1 \\ 5 & 5 & 1 \\ \end{vmatrix}\\ \notag&& \\[/tex]

The table shows the proportional relationship between a hedgehog's
weight loss and the number of days of hibernation. How much weight does
the hedgehog lose during 120 days of hibernation?
Explain how you know that the relationship between the hedgehog's weight
loss and the number of days of hibernation is proportional.
The hedgehog’s total change in weight over 120 days is ____ ounces.
Answer:
-3.6
Step-by-step explanation:
proportional means the amount on the right is amount on the left multiplied by some coefficient - proportion. The proportion is calculated by dividing one side by another. Since you need to calculate weight based on days, you need the proportion of weight/days, so divide -0.27/9 or -0.78/26, in all cases you'll receive -0.03. This means for each day in hibernation hedgehog loses 0.03 pounds. 120 days will be 120*-0.03 which gives you -3.6

The length and the weight of the 12 pipe is found as 42 meters and 74.23 kg
What is referred as the unitary method?"It is a method in which we obtain the value of a single unit by subtracting the results of multiple units and thus the value of multiple units by subtracting the value of a single unit."We must first divide to discover the value of one thing, and then multiply to determine the significance of more or fewer things.As, per the given question;
For, the seven pipes, the length is 24.5m.
7 pipes ---------> 24.5 m.
For the one pipe, use unitary method for solving;
Divide the equation by 7.
1 pipe -------->24.5/7 m.
For 12 pipes, multiply with 12 on both sides.
12 pipes --------> 24.5×12/7 m.
12 pipes ---------> 42 m.
Thus, the length of the 12 pipes is 42 meters.
Now, calculate the weight.
For, the seven pipes, the weight is 43.3 kg.
7 pipes ---------> 43.3 kg.
For the one pipe, use unitary method for solving;
Divide the equation by 7.
1 pipe -------->43.3 kg./7
For 12 pipes, multiply with 12 on both sides.
12 pipes --------> 43.3 kg×12/7

Determine the solutions of the equation:
x = −11 and x = 5
x = −81 and x = 45
x = −99 and x = 45
x = −99 and x = 99
The solutions of the absolute value equation are x = −99 and x = 45.
How to determine the solutions of the absolute value equation?Here we have the absolute value equation:
| (1/3)*x + 9| - 3 = 21
First, we can add 3 in both sides so we get:
| (1/3)*x + 9| = 21 + 3 = 24
This can be decomposed into two equations, we will get:
(1/3)*x + 9 = 24
(1/3)*x + 9 = -24
Solving these two we can get the two solutions.
The first one gives.
(1/3)*x = 24 - 9 = 15
x = 3*15 = 45
The second one gives:
(1/3)*x = -24 - 9 = -33
x = 3*-33 = -99
The solutions are x = −99 and x = 45.

Find the point-slope equation for

the first point in your equation.
y - [?] = [](x-[])
The point slope equation for the line that passes through the points (-2, -20) and (9, 79) is 9 x - y - 2 = 0.
We are given the points as:
(- 2 , - 20) and ( 9 , 79)
We will first find the slope:
Slope = m = y₂ - y₁ / x₂ - x₁
m = 79 + 20 / 9 + 2
m = 99 / 11
m = 9
Now, we have to find the point-slope equation for the line that passes through the points (- 2, - 20) and (9, 79).
The point slope equation is:
y - [y₁] = [m](x-[x₁])
Substituting the values, we get that:
y + 20 = 9 ( x + 2 )
y + 20 = 9 x + 18
9 x - y + 18 - 20 = 0
9 x - y - 2 = 0
Therefore, the point slope equation for the line that passes through the points (-2, -20) and (9, 79) is 9 x - y - 2 = 0.
