Answer:
The area of the shaded portion is 123 cm^2
Step-by-step explanation:
Here, we want to find the area of the shaded portion
To find this, we subtract the area of the smaller inner rectangle from that of the outside bigger one
Mathematically, the area of a rectangle at any point in time is length * width
For the bigger one, we have;16 * 9 = 144 cm^2
For the smaller inner one, we have ;3 * 7 = 21 cm^2
The area of the shaded portion which is the difference is;
144-21 = 123 cm^2

Step-by-step explanation:
Given
y = 2x - 3
if x = - 4 Then
y = 2 * ( -4) - 3
= -8 - 3

Hope it will help :)
The value of y when the value of x is equal to the negative number 4 is negative 11 (-11).
What is an unknown variable?Unknown variables are used to find the unknown values of the problem using the algebraic expressions.
The expression for the variable x and y are given as,
[tex]y=2x-3[/tex]
The x value for the above expression is given as,
[tex]x=-4[/tex]
The value of y for the above value of x has to be found out. Put the value of x in the given expression to find the value of variable y as,

Erin created a scale drawing for a garden that will be 10 ft by 5 ft. She plans to include a section in the garden for herbs, which will be 2 ft by 5 ft. On Erin’s scale drawing, the entire garden is 12 in. by 6 in. What are the dimensions of the herb garden on the scale drawing?
(GIVING BRAINLIEST) if you solve it
Answers
Answer:
The dimensions of the herb garden on the scale drawing are 2.4 by 6 inches
Step 1 (finding the scale factor):
12/10 (inches/feet) or 1.2 (inches/feet)
(1.2 inches in the drawing represent 1 foot in real life)
Step 2 (finding the dimensions of the herb garden on the scale drawing):
Real life dimensions are 2ft by 5ft so we multiply by the scale factor:
2ft = 2 x 1.2 = 2.4 inches
5ft = 5 x 1.2 = 6 inches
So the dimensions of the herb garden on the scale drawing are 2.4 by 6 inches.

acres of old-growth trees are there?
There are acres of old-growth trees.
Type an integer or a decimal)
Answers
Answer:
143 acres.
Step-by-step explanation:
To find how many acres of old-growth trees there are, we need to find what 0.2% of 73,000 is.
To find a percent of a number, multiply the percent by the number.
0.2% is equal to 0.002.
73,000 x 0.002 = 143
So, 143 acres of the forest is old-growth trees.

12x + 3y =8
-4x = y + 8
Answers
Answer:
8x + 2y
Step-by-step explanation:
12x + 3y = 8 you need to transfer the no. 8 to left since it's positive, it will be negative once you tranfer that and the result is this 8x + 3y -8 =0. Then do it again on the second given, -4x = y + 8.
Tranfer the y variable to left, y is positive then it will be a negative. No need to transfer the no. 8. Then the result would be -4x - y + 8=0
To this solve this, wrote it like this:
12x + 3y –8
-4x - y + 8

Brady rented a car for two days at $25 a day plus
$0.15 per mile. If his total bill came to $102.50, how
many miles did Brady drive?
Answers
Answer:
He drove 350 miles.
Step-by-step explanation:
I need points.
Brady drove 16.67 miles extra.
What is division?One type of operation in mathematics is division. We divide the expressions or numbers into the same number of components during this operation.
Given, Brady rented a car for two days at $25 a day plus $0.15 per mile.
His total bill is $102.50.
We divide the 102.50 by 25.
That means, 102.50 / 25
= 4 is quotient and 2.50 is remainder.
Now we divide 2.50 by 0.15
That means, 2.50 / 0.15
= 16.67 miles
Therefore, 16.67 miles, Brady drove.

Parallelogram PQRS is shown on the coordinate grid. Parallelogram PQRS is dilated with the origin as the center of a dilation using the rule (x, y) → (1.5x, 1.5y) to create parallelogram P'Q'R'S'.
Which statement is true?
A) Parallelogram P'Q'R'S' is larger than parallelogram PQRS, because the scale factor is greater than 1.
B) Parallelogram P'Q'R'S' is smaller than parallelogram PQRS, because the scale factor is less than 1.
C) Parallelogram P'Q'R'S' is smaller than parallelogram PQRS because the scale factor is greater than 1.
D) Parallelogram P'Q'R'S' is larger than parallelogram PQRS, because the scale factor is less than 1.
Answers
Answer:
C) Parallelogram P'Q'R'S' is smaller than parallelogram PQRS because the scale factor is greater than 1.
Step-by-step explanation:
1.5x, 1.5y is greater than 1 for the value of x.y
Explanation:
In terms of PQRS, the parallelogram will be seen as the ratio x:1 and y:1 The new figure, P’Q’R’S will have a ratio of x:1.5 y:1.5.
Because P’Q’R’S has a larger ratio of that than the original parallelogram, the resulting figure will be larger than the original shape PQRS.
(This can also be proven in terms of dilating by a scale factor of 0.5, as this will be a smaller figure than that of the original, further proving the claim.

Step-by-step explanation:
Slope is equal to the change in y over the change in x , or rise over run.
m = change in y /change in x
The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).
m = y 2 − y 1/ x 2 − x 1
Substitute in the values of x and y into the equation to find the slope.
m = 8 − ( 0 ) /3 − ( 1 )
Simplify.
Simplify the numerator.
m = 8 /3 − ( 1 )
Simplify the denominator.
Multiply − 1 by 1
m = 8 /3 − 1
Subtract 1 from 3

what is this 59 divided 535
Answers
Answer:
9.07 [Rounded]
Step-by-step explanation:
535 divided by 59 is 9.07, which I rounded.
The value of the division 535 ÷ 59 is 9 with a remainder of 4 and the decimal form can be expressed as 9.067.
To find the value of division 535 ÷ 59, we can perform a long division.
To perform the calculation, we can use long division:
59 ) 535 ( 9
- 531
______
4
Divide the first digit of the dividend (5) by the divisor (59). Since 5 is less than 59, we bring down the next digit, making it 53.
Divide 53 by 59. The result is 0, as 53 is less than 59.
Bring down the next digit, making it 535.
Divide 535 by 59. The result is 9, as 59 can go into 535 nine times.
Multiply 9 by 59, which equals 531.
Subtract 531 from 535, which gives us a remainder of 4.
Therefore, the value of the division 535 ÷ 59 is 9 with a remainder of 4.
In decimal form, the division can be expressed as 9.067, indicating that 59 goes into 535 nine times with a remainder of 4.
