Answer:
Step-by-step explanation:
I see that you want to find the equation of a linear function that forms a right triangle with the x-axis, y-axis, and has an area of 50 square units. To clarify, let's work through this step by step.
A right triangle can be formed with the x-axis and y-axis as two sides, and the third side represented by the graph of a linear function. The area of this right triangle can be found using the formula for the area of a triangle:
Area = (1/2) * base * height
In this case, one of the legs (base) of the right triangle is along the x-axis, and its length is determined by the x-coordinate at which the linear function crosses the x-axis. The other leg (height) is along the y-axis, and its length is determined by the y-coordinate at which the linear function crosses the y-axis.
Let's assume that the linear function is of the form:
f(x) = mx + b
where "m" is the slope and "b" is the y-intercept.
The x-coordinate where the linear function crosses the x-axis is given by:
x-coordinate = -b/m
The y-coordinate where the linear function crosses the y-axis is "b."
Now, let's calculate the area of the right triangle:
Area = (1/2) * (length of base) * (length of height)
Area = (1/2) * (-b/m) * b
Given that the area is 50 square units, we can set up the equation:
(1/2) * (-b/m) * b = 50
Now, you can solve this equation for "m" and "b" to find the equation of the linear function that satisfies the given conditions.
B. How high you can jump.
C. The time school starts.
D. The temperature outside is 31 degrees.
Answer:
For four days it would be $19.8. For seven days it would be $24.9
Step-by-step explanation:
4 days:
$4.70 x 4 + 1= 19.8
7 days:
$4.70 x 7 = $24.9
I took away 1 from the 4 day equation because the question said you get a dollar off if you return the dvd before 5 days.
Hope this helps!

Answer:
Length = 14
Width = 7
Step-by-step explanation:
Length of a rectangle is twice its width.
let, the width be x, so the length becomes 2x
now the perimeter is 42, and we know the formula to find the perimeter is 2(length+width)
so, 2(2x+x)=42
or, 2×3x=42
or, 6x=42
or, x=7
so the width is 7 and the length is, 2×7 = 14
