Answer:r+(2r+7)
Step-by-step explanation:
the number of gallons of bottled water N consumed by a person in one year is approximated by N=0.733t + 8.398, where t is the number of years since 1971. Predict the number of gallons consumed by a person in 1985.
Step-by-step explanation:
N = 0.733t + 8.398
N = 0.733(1971) + 8.398
N = 1,453.141
Step-by-step explanation:
Solution,
According to question,
N=0.733t + 8.398
When t= 1971, then
N=0.733×(1971) + 8.398
N=1453.141

Answer:
42x - 21 - 9x^2
Step-by-step explanation:
basically do the area of the whole rectangle then di the area of one of the empty spaces. then subtract the value of the empty space three times because there are three empty spaces.
Step-by-step explanation:
Let
[tex]A_1[/tex] = area of the small rectangle
[tex]\:\:\:\:\:= x(3x + 1) = 3x^2 + x[/tex]
[tex]A2[/tex] = area of the large rectangle
[tex]\:\:\:\:\:= (4x + 3)(10x - 7)[/tex]
[tex]\:\:\:\:\:= 40x^2 - 28x + 30x - 21[/tex]
[tex]\:\:\:\:\:= 40x^2 + 2x - 21[/tex]
Since there are 3 small rectangles, the area A of the shaded area is
[tex]A = A_2 - 3A_1[/tex]
[tex]\:\:\:\:= (40x^2 + 2x - 21) - 3(3x^2 + x)[/tex]
[tex]\:\:\:\:= 40x^2 + 2x - 21 - 9x^2 - 3x[/tex]
[tex]\:\:\:\:= 31x^2 - x - 21[/tex]

Write an equation in slope-intercept form for the line described. x-intercept (-8,0), y-intercept (0,5) The equation of the line is y nothing.
Answer:
y= 5/8 x +5
8y=5x +40
Step-by-step explanation:
x-intercept is (-8,0)
y-intercept is (0,5)
the slop of line: m= Δy/Δx = (0-5) / (-8-0) = 5/8
y=mx+b
y= 5/8 x +5
8y=5x +40

1. if f(x)=3x-1, find f(-5)
2. if h(x)=2x+3 and g(x)=3-4x, find 3h(1)-g(2)
Answer:
1 f(-5) = 3(-5)-1= – 15 – 1 = – 16
2. h(1) = 2(1)+3=2+3=5
g(2)= 3- 4(2)=3 – 8 = – 5
3h(1) ‐ g(2) = 3 (5) – (-5) = 15 +5= 20
I hope I helped you^_^
Answer:
number 1 =
Let y=f(x)=3x−5
Clearly f(x) is one-one onto function so it is invertible.
y=3x−5 ⇒x = y+5/3
∴f −1 (x)= y+5/3
number 2=
(g-h)= 4x+3-x3-2x3
(g-h)=4(-1)+3-(-1)2-2(-x)2
(g-h)=-4+3-(-1)-2(1)
(g-h)=-4+3+1 -2
(g-h) = 2

Create a 2-step equation
that has p = 0.5 as its
solution.
pls help! :)
Two step equations are equations which take 2 steps to solve. Let's create our equation now.
2p + 2 = 3
If you'd like, you can solve it to ensure it's correct.
2p + 2 = 3
Subtract 2 from both sides.
2p = 1
Divide both sides by 2
p = 0.5
