Function f is defined by the equation f(x) = x2 1. What is f(2) ?
Answer:
42
Step-by-step explanation:
So you basically replace the x with 2. So f(x) = x21, then it would change to f(2) = 2(21). Then you would just multiply 21 by 2 and you would get 42.
Hope this helps!
Answer:
f=x21=x2f(2)=4

Step-by-step explanation:
Braxton has money in a savings account. The equation B = 800(1+0.03)'.
can be used
to calculate the amount of money in dollars, B, Braxton has in his account after t years since
opening the account.
Pam also has money in a savings account. The equation P = 800(1 + 0,04) can be
used to calculate the amount of money in dollars, P, Pam has in her account after t years
since opening the account.
Choose from the drop down menus to correctly complete each sentence.
Braxton's initial investment Choose...
Pam's initial investment.
The interest on Braxton's account Choose...
the interest on Pam's account.
Answer:
a) Braxton's initial investment is equals to (=) Pam's initial investment.
b)The interest on Braxton's account is less than (< ) the interest on Pam's
account.
Step-by-step explanation:
Given - Braxton has money in a savings account. The equation
B = [tex]800(1 + 0.03)^{t}[/tex] can be used to calculate the amount of money
in dollars, B, Braxton has in his account after t years since opening
the account. Pam also has money in a savings account. The
equation, P= [tex]800(1 + 0.04)^{t}[/tex] can be used to calculate the amount of
money in dollars, P, Pam has in her account after t years since
opening the account.
To find - a) Braxton's initial investment ..........Pam's initial investment.
b) The interest on Braxton's account .....the interest on Pam's
account.
Proof -
As given, Broxton equation is -
Pam equation is -
Now,
a.)
For initial investment , Put t = 0
⇒B = [tex]800(1 + 0.03)^{0} = 800(1) = 800[/tex]
P = [tex]800(1 + 0.04)^{0} = 800(1) = 800[/tex]
We can see that for t = 0
Initial investment of Braxton = Initial investment of Pam
⇒Braxton's Initial investment = Pam's initial investment.
b.)
For the interest,
As we have not given any time period for which the interest has to be find.
So , let the time period , t = 5 years
Therefore,
B = [tex]800(1 + 0.03)^{5} = 800(1.03)^{5} = 800(1.159) = 927.42[/tex]
P = [tex]800(1 + 0.04)^{5} = 800(1.04)^{5} = 800(1.217) = 973.32[/tex]
Now,
Interest on Braxton's account = 927.42 - 800 = 127.42 ≈ 127
Interest on Pam's account = 973.32 - 800 = 173.32 ≈ 173
∴ we get
The interest on Braxton's account is less than the interest on Pam's account.

Find the measure of angle TUY
Answer:
120
Step-by-step explanation
Exterior angle theorem:
d = a + b
d = 70 + 50
d = 120
Answer: TUY: 120°
Step-by-step explanation:
Hello,
1. Recall that the sum of a triangle’s angles is 180°, regardless of the type of triangle.
2. Find TUS, that is, the angle for U.
U = 180°-(50°+70°)=60°
For TUY:
Knowing that U=60° and that the line above U is 180°:
180°-60°=120°
Write an equation to represent 'twice a number (x) is fifty"
Answer:
2x=50
Step-by-step explanation:
Hi there,
Your question is "twice a number (x) is fifty"
Recall how a number is represented by x.
Twice a number would be represented as 2x.
Therefore, to represent that twice a number is equal to 50, that would result in the expression: [tex]2x=50[/tex]
If you're looking to solve this equation, it's often best to think about the "reverse" of the current equation.
Notice how 2 is multiplying the x.
To isolate x, divide that side by 2.
However, recall that whatever is done to one side of an equation must also be done to the other side of the equation. Therefore, you will need to divide both sides by 2.
[tex]2x=50[/tex]
[tex]\frac{2x}{2} = \frac{50}{2}[/tex]
[tex]x=25[/tex]
Equation: [tex]2x=50[/tex]
Solving for x: 25
Hope that helps!

-3x + y= – 8
3x + 2y = – 13
X =?
y =?
Answer:
x=1/3
y=-7
Step-by-step explanation:
using the elimination method, you can add both equations vertically, to eliminate the x
-3x+y=-8
3x+2y=-13
3y=-21
y=-7
we then fix the value of y into the first equation
-3x+y=-8
-3x-7=-8
-3x=-8+7
-3x=-1
x=1/3

5. The table below represents a quadratic function: draw a graph plot points
What would be the axis of symmetry for the equation?
What is the vertex?
What are the roots?
What is the y-intercept?
Answer:
The extreme point ( maximum or minimum ) of a parabola is called the vertex, and the axis of symmetry is a vertical line that passes through the vertex. The x-intercepts are the points at which the parabola crosses the x-axis. If they exist, the x-intercepts represent the zeros, or roots, of the quadratic function.
Step-by-step explanation:
The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.
Find the value of the expression 12y - 2xy, when x = 5 and y = 10.
Answer:
12y-2xy
x=5, y=10
(12x10) -(2x5x10)
=120-100
=20
Step-by-step explanation:
1.first collect the information you have been given in the question to make answering of the question easy.
2.then substitute the x value (in this case 5) and the y value (10) into the expression 12y - 2xy on there respectful positions.
3.having done so, you can then multiply and thereafter subtract as the question requires you to do.
Note: only substitute the y and x values where y and x appear in the question.
Always start with multiplying, after substituting,before subtracting or adding.

3. 4.5x + 10 (I think, not quite sure)
4. 0.25 - 5x (I think, also not quite sure)
5. -8x - 5y + 5.5
Step-by-step explanation:
2. Distribute the -2 to all terms except -1.
-2(4x + 2.5) - 1
-8x - 5 -1
-8x - 6
5. Combine 6x and -14x (6 - 14 = -8).
6x - 5y - 14x + 5.5
-8x - 5y + 5.5
