Answer:
6m + 3n.
Step-by-step explanation:
The area of a trapezoid = h/2 (a + b), where h = altitude and a and b are the lengths of the opposite parallel sides.
So here:
h = 6, a = m and b = m+n.
So area = 6/2(m + m + n)
= 6/2(2m + n)
= 3(2m + n)
= 6m + 3n.
Hey there!
First, we'll solve for x = 0.
The first step is to replace x with 0 anytime it appears in the equation.
f(0) = 7(0) + 2
Multiply 7 by 0 next because multiplication comes before addition in PEMDAS.
f(0) = 0 + 2
Then, add 2 to 0 since it is the last step.
f(0) = 2 The value of f(x) when x = 0 is 2.
Now we can solve for x = 1.
The first step is to replace x with 1 anytime it appears in the equation.
f(1) = 7(1) + 2
Multiply 7 by 1 next because multiplication comes before addition in PEMDAS.
f(1) = 7 + 2
Then, add 2 to 7 because it is the last step.
f(1) = 9 The value of f(x) when x = 1 is 9.
Hope this helps!
First find the slope/rate of change of the table. Find the difference between the intervals of the x and y values of the table. Each time the x value decreases by 2 the y value decreases by 4. To find the rate of change divide the -4 by -2 to get 2 as the slope.
Set up an equation using values from the table to figure out the y intercept or b value.
-6=-4(2)+b
-6=-8+b. Add 8 from both sides
both sides to get b
2=b
The y intercept is (0,2)
The equation of the line is Y=2x+2
Plug in 0 for y into the lines equation to get the x intercept
0=2x+2
-2=2x. Divide by 2 to isolate x
-1=x
The x intercept is (-1,0)
Answer:
The inequality shown is 5.
Step-by-step explanation:
It's just asking for the inequality so you can basically just add the distance like 4 + 5 = 9.
Answer:
No
Step-by-step explanation:
1. 5 cups of cornmeal=2 cups of water. Using 115 cups of cormeal would mean you need 287.5 cups of water, not 3.
3 is too little
2: If you use 5 cups of water for every 3 cups of cornmeal, for 3 cups of cornmeal you'd need like 6.5 cups of water, not that high of a number.
