Answer:
(x,y)--> (2,1), (4, -5), (7, -14), (9, -20), (11, -26)
Step-by-step explanation:
y = -3x + 7
substituting x-values in y= -3x + 7
x = 2
y= -3 × 2 + 7
= -6 + 7
= 1
x=4
y= -3 × 4 + 7
= -12 + 7
= -5
x=7
y= -3 × 7 + 7
= -21 + 7
= -14
x=9
y= -3 × 9 + 7
= -27 + 7
= -20
x=11
y= -3 × 11 + 7
= -33 + 7
= -26
The table for the linear relationship, y = - 3x + 7 is shown below
What is the equation of line?The equation of a straight line is a relationship between x and y coordinates, The general equation of a straight line is y = mx + c, where m is the slope of the line and c is the y-intercept.
Given that,
A equation of a line,
y = - 3x + 7
And Values of x,
2, 4, 7, 9, 11
Now, values of y for particular values of x
When x = 2
y = - 3 × 2 + 7
= 1
When x = 4
y = - 3 × 4 + 7
= -5
When x = 7
y = - 3 × 7 + 7
= - 14
When x = 9
y = - 3 × 9 + 7
= -20
When x = 11
y = - 3 × 11 + 7
= -26
The table for values of y
x: 2 4 7 9 11
y: 1 -5 -14 -20 -26

I NEED HELP ASAP!! just question 2 and 3!!
Answers
Answer:
2. 3
3. 125
Step-by-step explanation:
2. You have four squares with a total area of 36. Divide the area by 4 to find the area of 1.
36/4=9
The Area of 1 square is 9. That means that the side of a square is 3.
3. A cube has a side of 5 inches. All the sides of a cube are the same, and the volume formula is l*w*h = V
You can input the number into the equation. 5 * 5 * 5 = V
You can also read this as 5^3.
The Volume = 125

Write the point-slope equation of the line that passes through (7,3) whose
slope is 2.
Answers
Answer:
y - 3 = 2(x - 7).
Step-by-step explanation:
The point-slope form is
y - y1 = m(x - x1) where m = slope and (x1, y1) is a point on the line.
So the answer is:
y - 3 = 2(x - 7).

Tyler and frazer weigh a total of 23kg.tyler is 7kg heavier than frazer.How much do they each weigh
Answers
Answer:
Frazer is the 8kg and Tyler is 15 kg.
Step-by-step explanation:
Total 23kg. Take away the 7kg, that Tyler weighs more, is 16.
Half the 16 to get 8.
please mark as the brainliest
Tyler and frazer weigh a total of 23kg then Frazer weighs 8 kg and Tyler weighs 15 kg.
Now assume Frazer's weight as x.
According to the problem, Tyler is 7kg heavier than Frazer.
Hence, Tyler's weight will be x + 7.
Now We know that the total weight of both of them is 23 kg.
Therefore, the equation will be:
x + (x + 7) = 23
Simplifying the equation, we get:
2x + 7 = 23
Now, subtracting 7 from both sides of the equation, we get:
2x = 16
Dividing both sides by 2,
x = 8
So, Frazer weighs 8 kg.
Now, we can calculate Tyler's weight as:
x + 7 = 8 + 7 = 15 kg
Therefore, Tyler weighs 15 kg.

John sells t-shirts. Plain shirts cost $5 and graphic shirts cost $7.
In order to match his product costs, he must make at least $1,200.
Answers
Okay so is your question like how many plain and graphic he needs to sell to get more than $1200??
For example if he sells 100 plain shirts(which will come up to $500) and 100 graphic shirts($700) the Total amount earned would be $1200, so we would need to sell at least 100 shirts of each or more to get to $1200.
Also if he sells 240 plain shirts he will get $1200
Or if he sells 172 graphic shirts he will get $1204.

Which fraction converts to a repeating decimal number?
OA. 1/12
OB. 7/8
OC. 14/25
OD. 17/20
OE. 6/10
Answers
=======================================================
Explanation:
Using a calculator shows that
1/12 = 0.0833333.... where the 3's go on forever7/8 = 0.87514/25 = 0.5617/20 = 0.856/10 = 0.6We see that nearly all of the decimal values are terminating decimals. This means the decimals don't go on forever, so the decimals stop at some point.
Only 0.083333... goes on forever, so that's why 1/12 converts to a repeating decimal number.
----------------------
A way you can determine this without a calculator is to use long division. Or you could use the idea that if the denominator has prime factors other than 2 and 5, then the decimal will repeat forever.
Note how the denominators of the fractions for choices B through E all have prime factors of either 2s only, 5s only, or a mix of 2s and 5s. This fact is why we have terminating decimals here.
In contrast, 12 has prime factorization 2*2*3. That 3 as a prime factor is why the decimal repeats forever.
The only fraction that converts to a repeating decimal number is 1/12.
What is decimal?Decimal is a fraction whose denominator is a power of ten and whose numerator is expressed by figures placed to the right of a decimal point.
Given is to find a fraction that converts to a repeating decimal number.
Repeating decimals are the decimals of the form -
2.7777...
2.34343434...
2.43434343....
Now, we have the fractions and their corresponding decimal numbers as follows -
1/12 = 0.0833333333333333 : Yes7/8 = 0.875 : No14/25 = 0.56 : No17/20 = 0.85 : No6/10 = 0.6 : NoTherefore, the only fraction that converts to a repeating decimal number is 1/12.

Let's solve your equation step-by-step.
2/3x−4 1/2=−8
Step 1: Simplify both sides of the equation.
2/3x+−9/2=−8
Step 2: Add 9/2 to both sides.
2/3x+−9/2+9/2=−8+9/2
2/3x=−7/2
