f(t) = 2t - 3 f(7) =
Answer:
f(7) = 11
Step-by-step explanation:
t = 7, so we can just plug in the value 7 for (t) in the given equation.
f(t) = 2t - 3
f(7) = (2 × 7) - 3
f(7) = 14 - 3
f(7) = 11
If a rectangle has the sides 5x-3 and 6x-4 what is the area and perimeter
Step-by-step explanation:
[tex]A = lw[/tex]
[tex]A=(5x-3)(6x-4)[/tex]
[tex]A=30x^2-20x-18x+12[/tex]
[tex]A=30^2-28x+12[/tex]
[tex]P=2(l + w)[/tex]
[tex]P = 2(5x - 3 + 6x - 4)\\P=2(x-7)\\P=2x-14[/tex]
Answer:
[tex]Perimeter = 22x - 14[/tex]
[tex]Area = 30 {x}^{2} - 38x + 12[/tex]
Step-by-step explanation:
Length of rectangle (l) = 5x - 3
Weidth of rectangle (w) = 6x - 4
Perimeter of the rectangle = [tex]2(l + w)[/tex]
[tex] = > 2(5x - 3 + 6x - 4)[/tex]
[tex] = > 2(11x - 7)[/tex]
[tex] = > 22x - 14[/tex]
Area of the rectangle = [tex]l \times w[/tex]
[tex] = > (5x - 3)(6x - 4)[/tex]
[tex] = > 5x(6x - 4) - 3(6x -4)[/tex]
[tex] = > 30 {x}^{2} - 20x - 18x + 12[/tex]
[tex] = > 30 {x}^{2} - 38x + 12[/tex]

If an article was bought for £400 and was sold for £336 what is the loss persentages
Answer:
Hey mate!
Here is your answer > >
C.P of an article=Rs.400
S.P.of an article=Rs.336
C.P.> S.P., there is a loss
Loss=C.P.-S.P.
=> Loss=400-336
=Rs.64
Loss%=Loss/C.P.×100
=64/400×100
=16%
Hope it helps!
Thankyou ☆ ☆

Earl runs 50 meters in 20 seconds. How many meters does Earl run per second?
Answer:
2.5 meters
Step-by-step explanation:
Answer:
Earl can run 2.5 meters in one second.
Step-by-step explanation:
We know that Earl can run 50 meters in 20 seconds. That means he can run 150 meters in one minute and 9,000 meters (or 9 kilometers) in one hour. 50 meters / 20 seconds = ? meters / 1 second
50 meters / 20 seconds = x / 1 second
(50 x 1) = (20) (x)
50 = 20x divide both sides by 20 to get the "x" alone
50 / 20 = x
2.5 = x

Which functions are even? Check all of the boxes that apply.
f(x) = x2 – 3x + 2
7x) = -2)
f(x) = |x|
Answer:
C) f(x) = |x|
Step-by-step explanation:
Determine if Odd, Even, or Neither
f (x) = |x|
Find f (−x) by substituting −x for all occurrence of x in f (x). f(−x) = |−x|
Make −x positive.
f(−x) = |x|
A function is even if f(−x) = f(x).
Check if f(−x) = f(x).
|x| = |x|
Since |x| = |x|, the function is even.

The circulation of a newsletter decreased from 3,200 to 2,400. What was the percent of the decrease in circulation?
Answer:
75%
Step-by-step explanation:
Find the median: In a particular year, approximately 1.7 million people took the mathematics section of a college achievement test. Of these, 44% scored less than 490, 45% scored less than 500, 48% scored less than 510, 51% scored less than 520, and 57% scored less than 530. In what interval is the median score? The median score is in the interval â–¼(Choose one).
Answer:
the median score would be between 510 and 520
Step-by-step explanation:
The computation of the median score is shown below
In the case of the continuous probability distribution, the median value is the mid value in which the number is equal to fall to above or below it
Here
P(X = median) = 0.5 = 50%
So the median score would be between 510 and 520
Hence, the same is to be considered

8x-1
C
Answer:
x=8
Step-by-step explanation:
Triangle DCE is similar to EGF
CE/EF=DE/EG
Substitute
(8x-1)/21=(6x+3)/17
Cross multiply
(8x−1)*(17)=(6x+3)*(21)
136x−17=126x+63
Subtract 126x from both sides
10x−17=63
Add 17 to both sides.
10x−17+17=63+17
10x=80
Divide both sides by 10.
x=8
