Choose the function that represents the data in the table.

Mathematics
1 answer:
Usimov [2.4K]3 years ago
3 0

<u>Given</u>:

It is given that the function represents the data in the table.

We need to determine the function.

<u>Slope</u>:

The slope can be determined using the formula,

m=\frac{y_2-y_1}{x_2-x_1}

Let us substitute the coordinates (1,6.5) and (4,8) in the above formula, we get;

m=\frac{8-6.5}{4-1}

m=\frac{1.5}{3}

m=0.5

Thus, the slope is 0.5

<u>y - intercept:</u>

The y - intercept is the value of y when x = 0.

Thus, from the table, when x = 0 the corresponding y value is 6.

Therefore, the y - intercept is b=6

<u>Equation of the function:</u>

The equation of the function can be determined using the formula,

y=mx+b

Substituting the values m=0.5 and b=6, we get;

y=0.5x+6

Thus, the equation of the function is y=0.5x+6

Hence, Option C is the correct answer.

avanturin [10]

Answer:

z = 4

y = -1

x = 2

Step-by-step explanation:

x - y = 3

Therefore => x = 3 + y

y + 2z =7

Therefore => y= 7 - 2z

We have the equation :

2x + 3y + 4z = 17

2(3 + y) + 3(7 - 2z) + 4z = 17

6 + 2y + 21 - 6z +4z = 17

2(7 -2z) - 2z + 27 = 17

14 - 4z - 2z + 27 = 17

-6z + 41 = 17

-6z = -24

z = 4

10 more than 2 times a number is equal to 2 times the number plus 50. What is the number?
PSYCHO15rus [73]

Answer:

y = 40 is the answer

Step-by-step explanation:

Let the number be y

10 more than 2 times a number = 10 + 2×y

equal to 2 times the number plus 50. = 2 × y + 50

10 + 2y = 2y + 50

combine the like terms

2y - 2y =50 - 10

0 = 40

the number supposes be 40 but the number is represented by 0

i think some thing is missing in your question

y supposes be 40 not 0 = 40

Hope this helps!
