Consider the function, y= 2x – 1
use the above function to complete the following table.
Answer (numbers needed in boxes, going from top to bottom):
1
-1
-3
3
Step-by-step explanation:
f(x) is another way of saying y. So, the table is asking, "when substituting these x values for the x's in the function, what does y equal?" So, to answer the question, substitute each x value into the equation and solve.
1) Start with the x value of 1. Substitute 1 for x in y = 2x - 1 and solve:
[tex]y = 2(1)-1\\y = 2 - 1\\y = 1\\[/tex]
So, when x equals 1, y equals 1. Therefore, the first box on the top must be filled out with the number 1.
2) Do the same with the rest of the x values. Here are the steps to solve each one, going in order from the top towards the bottom:
x = 0
[tex]y = 2(0) - 1\\y = 0 - 1\\y = -1[/tex]
x = -1
[tex]y = 2(-1) - 1\\y = -2 -1 \\y = -3\\[/tex]
x = 2
[tex]y = 2(2)-1\\y = 4-1\\y = 3\\[/tex]
Sue bought 2 pairs of jeans and a belt that cost $6.95. The tax on the items was $5.85. Sue paid the cashier $70.00. How much money did Sue receive in change? Write you answer in a complete sentence.
Answer: Sue's change will be $57.20
Step-by-step explanation:
Sue bought 2 pairs of jeans and a belt for $6.95.
Sue also paid a tax of $5.85 for the items.
Sue gave the cashier $70, her change will therefore be:
= 70 - 6.95 - 5.85
= $57.20

Step-by-step explanation:
Since, lines are intersecting at point (2, 4).
Therefore, (2, 4) is the solution.
Given that p varies jointly as q and r, and p = 7. when q = 2
and r= 1.5, find the following:
a. an equation relating p, q, and r
b. p when q = 4 and r= 6
c. p when p=1 and r=3
d. r when p= 5 and q = 8
Answer:
P = k*q*r
Step-by-step explanation:
P = kqr
7 = k*2*1.5
7 = 3k
k = 7/3
b. P = kqr
= 7/3*4*6
= (7*4*6)/3
= 168/3
= 56
P = 56
c. P = kqr
1 = 7/3*q*3
1 = (7*q*3)/3
1 = 21q/3
Cross product
1*3 = 21q
3 = 21q
q = 3/21
= 1/7
q = 1/7
d. P = kqr
5 = 7/3*8*r
5 = (7*8*r)/3
5*3 = 56r
15 = 56r
r = 15/56

Kira had some money sitting in a savings account that earns 2.75% simple interest each year. She left it there for 8 years and earned $495 in interest. How much money did she have in the account to begin with.
Answer:
$2250
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 2.75%/100 = 0.0275 per year,
then, solving our equation
I = 2250 × 0.0275 × 8 = 495
I = $ 495.00
The simple interest accumulated
on a principal of $ 2,250.00
at a rate of 2.75% per year
for 8 years is $ 495.00.

The length of the base of an isosceles triangle is x. The length of a leg is 5x - 3. The perimeter of the triangle is 104.
Answer:
x = 10
Step-by-Step Explanation:
Since this triangle is an isosceles, that means two sides are the same and so being that two sides are the same, we can use this equation (5x - 3) • 2.
At first I tried 5, but soon after realized that it wouldn't be enough to make 104, so I doubled the number to 10.
x = 10
((5 • 10) - 3) • 2
(50 -3) • 2
47 • 2 = 94 ( sum of the two equal sides)
94 + 10 = 104

5. Mississippi and Georgia have a total of 21 electoral votes. Mississippi has 6 electoral votes. Use mental math or the guess, check, and revise strategy to solve the equation 6 + g = 21 to find g, the number of electoral votes Georgia has.
Answer: g = 15 . Georgia has 15 electoral votes.
Step-by-step explanation:
Mental math: How many do I need to make up the difference?
counting by 5s: 5, 10 15, 20.
6 is one more than 5.
From 5, three more 5's gets us close to 20. It works.
6 + 15 = 21

Answer: 15.199
Step-by-step explanation:
Using the Pythagorean theorem, we know that a²+b²=c²
In this case, we know that c is 16, and that b is 5.
We can rearrange the equation so that it becomes a²=c²-b²
a²=16²-5²
a²=256-25
a²=231
√a²=√231

I'm not smart and I stink at math so can someone plz help me 12/x = 8
1. We need to get rid of all the denominator in this equation.
This can be done by multiplying left and right sides by the LCD.In the problem: 12/x = 8, the LCD is X.12/x = 8 is now 12 = x * 8
1a. 8 * x = 8x
Now, your answer is 3/2, but It's improper. Let's convert it into a mixed number.
Subtract 3 by 2.
