Given the linear equation y=5x+7, fill in the table by choosing values for x, and calculating the corresponding y values. Use integer values for x.
Answers
when x = 1, y = 12 (y = 5*1+7)
when x = 2, y = 17 (y = 5*2+7)
Final answer:
To fill in the table for the equation y=5x+7, integer values for x are chosen and substituted into the equation to find the corresponding y values. The (x, y) pairs are then recorded in the table and can be plotted on a graph.
Explanation:
Filling in a Table for a Linear Equation
To fill in the table for the linear equation y=5x+7, let's choose integer values for x and calculate the corresponding y values. Here's how you do it step by step:
Pick an integer value for x (e.g., -1, 0, 1, 2, etc.).
Substitute this value of x into the equation to solve for y.
Record the (x, y) pair in the table.
For example:
If x = -1, then y = 5(-1)+7 = 2, so the point is (-1, 2).
If x = 0, then y = 5(0)+7 = 7, so the point is (0, 7).
If x = 1, then y = 5(1)+7 = 12, so the point is (1, 12).
If x = 2, then y = 5(2)+7 = 17, so the point is (2, 17).
Remember, the dependence of y on x represents the fact that y changes when x changes, according to the equation of the line. After calculating several points, you can plot these points on a graph, and they should form a straight line because they belong to a linear equation.

Now that you have the slope, we can use the equation of a line which is :
y - y1 = m(x - x1)
Substitute any coordinate.
I'll go with (1, 5)
y - 5 = 3(x - 1)
y - 5 = 3x - 3
y = 3x + 2
And that's the equation in the slope intercept form or y=mx+b.

Would you solve the equation 0.25x + 7 = 1/3x -1 using fractions or decimals? Explain. Please help I'm very confused! #40
Answers
0.25 is easy to change to a fraction. It's 1/4
However, 1/3 is not easy to change to a decimal because it would be the repeating decimal 0.333333(going on forever).
So basically it's just easier to change them both to fractions because 1/3 isn't a terminating decimal.
also, we can cancel fractions by multiplying by the least common denomenator
so, write 0.25x as 1/4x
1/4x+7=1/3x-8
times both sides by 12
3x+84=4x-96
minus 3x both sides
84=x-96
add 96 to both sides
180=x
x=180

The equation which represents the situation is:
[tex]x^2+6x-256=0[/tex]
Step-by-step explanation:Let x represent the width of the rectangle in centimeters.
The length of a rectangle is 6 cm more than its width.
This means that the length of the rectangle is: x+6 cm.
Also, we know that the area of a rectangle is the product of the length and width of the rectangle.
Here, the area of the rectangle is 256 cm².
i.e.
[tex]x(x+6)=256\\\\x^2+6x=256\\\\i.e.\\\\x^2+6x-256=0[/tex]

The cost of the ball is $0.05. This is determined through a simple algebraic calculation that takes into account that the bat costs $1.00 more than the ball and the total cost is $1.10.
The student's question is about solving a simple algebraic problem involving the cost of two items with a given difference in their prices. In the problem statement, a bat and ball cost a combined total of $1.10. The bat costs $1.00 more than the ball.
Let's denote the cost of the ball as x dollars.Consequently, the cost of the bat will be x + $1.00, since it costs one dollar more than the ball.According to the information provided, the combined cost of the ball and bat is $1.10. Therefore, we can write the following equation: x + (x + $1.00) = $1.10.Simplifying this equation: 2x + $1.00 = $1.10.Subtracting $1.00 from both sides of the equation, we get 2x = $0.10.Dividing both sides of the equation by 2, we find that x = $0.05.Therefore, the cost of the ball is $0.05.

254 mm*(1 m/1,000 mm) = 0.254 m
2. The perimeter of a rectangle is equal to
P = 2L + 2W
where
L is the length
W is the width
Since the length of a rectangle is one unit shorter than one-sixth of the width, x, the equation would be
W=x
L = 1/6x - 1
Substituting,
P = 2(1/6x - 1) + 2x
P = 1/3x - 2 + 2x
P = 7/3x - 2
3. The given data is 2 parts per second. To determine the parts per shift, we apply the dimensional analysis approach. The solution is as follows:

A survey was taken of 2000 voters before an election.1650 of the ones surveyed said they would vote for candidate A.What percent of those surveyed planned to vote for candidate A.
Answers
82.5% of the surveyed voters planned to vote for candidate A, calculated by dividing 1650 (voters for candidate A) by 2000 (total surveyed) and multiplying by 100.
It seems like there's a slight discrepancy in the given numbers. You mentioned 1650 voters for candidate A in the question, but then provided a different ratio (160/300) in the expression. Let's correct this.
To find the percentage of voters planning to vote for candidate A, we need to calculate the ratio of voters for candidate A to the total number of voters surveyed, then convert this ratio into a percentage.
Given:
- Number of voters for candidate A: 1650
- Total number of voters surveyed: 2000
We can calculate the ratio as:
[tex]\[ \frac{1650}{2000} \][/tex]
Now, let's find the percentage:
[tex]\[ \text{Percentage} = \left( \frac{\text{Number of voters for candidate A}}{\text{Total number of voters surveyed}} \right) \times 100 \][/tex]
[tex]\[ \text{Percentage} = \left( \frac{1650}{2000} \right) \times 100 \][/tex]
[tex]\[ \text{Percentage} = \left( 0.825 \right) \times 100 \][/tex]
[tex]\[ \text{Percentage} = 82.5\% \][/tex]
So, 82.5% of those surveyed planned to vote for candidate A.
Complete Question:
A survey was taken of 2000 voters before an election. 1650 of the ones surveyed said they would vote for candidate A. What percent of those surveyed planned to vote for candidate A.
First, we need to find the ratio of voters who planned to vote for candidate A to the total number of voters surveyed. This can be represented as: [tex]$\frac{160}{300}$[/tex]

Alyssa received $30,000 from an inheritance and invests part in a certificate of deposit (CD) paying 5% annual interest and the rest in Apple Inc. offering an annual return of 11%. If the annual income from her investments is $2,220, how much did Alyssa invest in each?
Answers
F = P (1+i)ⁿ, then,
A = F - P
A = P[(1+i)ⁿ - 1] = $2,220, where n=1 because annual means income per one year
Now, amount of P should be distributed such that the total would be $30,000. Thus, the equation should be
(30,000 - x)[1 +0.05 - 1] + x[1 + 0.11 - 1) = 2220
Solving for x,
x = 12,000
30,000 - x = 18,000
Hence, Alyssa placed $12,000 in the certificate of deposit, and $18,000 with Apple Inc.

Brianne is three times as old as Camila. Four years from now she will be two-times as old as Camila. How old are Brianne and Camila now?
Answers
c=camila present age
b=3c (brianne is three times as old as camila)
b+4=2(c+4) (four years from now she will be two times as old as Camila)
b + 4 = 2c + 8
b = 2c + 8 - 4
b = 2c + 4
Replace b with 3c
3c = 2c + 4
3c - 2c = 4
c = 4
Camila is four years old.
b+4=2c+8
b=2(4)+4
b=8+4
b=12
Brianne is 12 years old.
Age of Camila is: 4 years.
Age of Brianne is: 12 years.
Step-by-step explanation:Let the present age of Camila be : x
and the present age of Brianne be : 3x.
( Since, it was given that:
Brianne is three times as old as Camila )
Four years from now the age of Camila will be: x+4
and the age of Brianne will be: 3x+4
Now, it is given that:
Four years from now she will be two-times as old as Camila.
i.e.
[tex]3x+4=2(x+4)\\\\i.e.\\\\3x+4=2x+2\times 4\\\\3x+4=2x+8\\\\3x-2x=8-4\\\\x=4[/tex]
Hence, the age of Camila is: 4 years.
and the age of Brianne is: 12 years.
3.55 divided by 5=..... tenths divided By 5+......... hundredths divided by 5
Answers
3.55 divided by 5 = 35 tenths divided by 5 + 5 hundredths divided by 5
To solve 3.55 divided by 5 using place values, we can break 3.55 into tenths and hundredths:
3.55 can be written as 3.5 + 0.05.
Tenths: 3.5 = 35 tenths
Hundredths: 0.05 = 5 hundredths
Now, we can write:
3.55 divided by 5 = 35 tenths divided by 5 + 5 hundredths divided by 5
Let's verify.
3.55/ 5 = 0.71
35 tenths /5 = 7 tenths
5 hundredths /5 = 1 hundredths
Adding them: 7 tenths + 1 hundredths = 0.71
Thus, it is verified.
Hence, 3.55 divided by 5 = 35 tenths divided by 5 + 5 hundredths divided by 5
