I WILL MARK AS BRAINLIEST! Write and equation that represents the points on the table

Answers

Answer 1

Step-by-step explanation:

y = ax +b

2 = 0a+ b => b = 2

4 = -2a + b

4 = -2a +2

2a = 2-4

2a = -2

a = -1

so, y = -x + 2

Answer 2

Answer
y=-x+2
Hope it’s not wrong imma in need of more points so sorry bout that T-T

I WILL MARK AS BRAINLIEST! Write an Equation that represents the points in the table

Answers

Answer:

y = 3x + 5

Step-by-step explanation:

Based on the table, as x increases by 1, y increases by 3. Moreover, when x = 0, y = 5. Therefore, the slope is 3 and the y-intercept is (0, 5).

Substitute the information for the variables in the slope-intercept form equation.

y = mx + b

m = slopeb = y-intercept value

Answer:

y=3x +5

Answer:

485 × [tex]10^{-10}[/tex]

Step-by-step explanation:

first we need to convert the number to fraction

0.0000000485

[tex]\frac{0.0000000485}{10000000000}[/tex]

it will be

[tex]\frac{485}{10000000000}[/tex]

or can be written as

[tex]\frac{485}{10^{10} }[/tex]

now we need to convert it to scientific notation

To find the average of a student’s test scores, add the scores and divide by the number of tests. Suppose Ryan scored 85, 92, 88, and 98 on four tests. Write a numerical expression to describe Ryan’s average test score.

Answers

x= (85+92+88+98)/4
The slash means to divide. So you’re making a fraction with all the scores on top and the number of scores on the bottom.

Answer:

(85+92+88+98)/4

Step-by-step explanation:

No equal sign because it is a numerical expression.

1 + (-5/8) = 3/8

Explanation: If the coffee wasn’t drank it would’ve been at fraction 1 (or 100%)

Since he drank 5/8 of it. The coffee left is now 1-(5/8)

But since the question has asked to give the equation in addition format. Put a plus sign in between the two.

Therefore,
1 + (-5/8)

Solve it,
= 1-(5/8)
= (8-5)/8
= 3/8

Hence the equation is:

1 + (-5/8) = 3/8.

Answer: Therefore,

1 + (-5/8)

Solve it,

= 1-(5/8)

= (8-5)/8

= 3/8

Answer:

h = S/(2 π r) - r

Step-by-step explanation:

Solve for h:

S = 2 π r (r + h)

S = 2 π r (r + h) is equivalent to 2 π r (r + h) = S:

2 π r (r + h) = S

Divide both sides by 2 π r:

r + h = S/(2 π r)

Subtract r from both sides:

Answer: h = S/(2 π r) - r

Answer:

h=s/(2 π r) -r

Step-by-step explanation:

since it is being divided by 14, the denominator of the fraction is 14. the remainder is 10, so the answer should be in the form of x 10/14, which the 1st answer is
