Step 1: Define Systems
y = -3x + 10
y = -2x + 6
Step 2: Solve for x
Substitution
Substitute in y: -3x + 10 = -2x + 6Add 3x on both sides: 10 = x + 6Isolate x: 4 = xRewrite: x = 4Step 3: Solve for y
Define equation: y = -2x + 6Substitute in x: y = -2(4) + 6Multiply: y = -8 + 6Add: y = -2An airplane cuts through the morning sky.

Complete the steps below to answer the question.
i know I already posted this but the answer was no help and I doubt other people would reply to the first one
part A: Write the change in elevation and the change in temperature as rational numbers.
part B: Write a numerical expression to represent the rate of temperature change in degrees Fahrenheit per foot.
part C: What is the rate of temperature change in degrees Fahrenheit per foot?
part D: Now, consider the reverse situation: as the airplane descends, or drops, 1,000 feet in the air, the temperature rises 20 degrees Fahrenheit. Write a numerical expression representing the rate of temperature change in degrees Fahrenheit per foot.
part E: What is the rate of temperature change in degrees Fahrenheit per foot?
part F: How is the rate you found in part E related to the rate you found in part C? What does this mean?

Step-by-step explanation:
Solve -16x = -80. A. -64, B. -5, C. -96, D. 5
-16x= -80
x has to be a positive number in order to be multiplied by a negative number and still get a negative answer. Therefore D is the only correct option.
Answer:
B. -5
Step-by-step explanation:
-16x = -80
Divide both sides by -16, so that the x stands alone
(-16x) / (-16) = (-80) / (-16)
The two -16's cancel each other out on the left side
x = 80 / -16
So now all we have is 80 divided by -16, which we can simplify to
x = -5

What is the surface area of this right rectangular prism glass slab with dimensions of 20 inches by 3 inches by 12 inches?
Answer:
the answer would be 240 since you are only looking for surface area, which means you wouldn’t include the width
dont sue me
Step-by-step explanation:
The surface area of the right rectangular prism glass slab is 672 square inches.
What is a prism?A prism is a three-dimensional object.
There are triangular prism and rectangular prism.
We have,
The surface area of a right rectangular prism can be calculated by adding up the areas of all six faces.
For a prism with dimensions of 20 inches by 3 inches by 12 inches, we can calculate the surface area as follows:
-The front and back faces have the same dimensions, so we can calculate the area of one and then double it:
Front and back area
= length x width
= 20 x 3 = 60 square inches
Now,
Total area for front and back.
= 2 x 60
= 120 square inches
The top and bottom faces also have the same dimensions, so we can calculate the area of one and then double it:
Top and bottom area.
= length x height
= 20 x 12
= 240 square inches
Total area for top and bottom.
= 2 x 240
= 480 square inches
The left and right faces also have the same dimensions, so we can calculate the area of one and then double it:
Left and right area.
= width x height
= 3 x 12
= 36 square inches
Total area for left and right = 2 x 36 = 72 square inches
The total surface area of the prism is the sum of the areas of all six faces:
Total surface area.
= 120 + 480 + 72
= 672 square inches
Thus,
The surface area of the right rectangular prism glass slab is 672 square inches.
