Let
<span>A (4,8) and B (3,5)

</span>step 1
find the slope m
m=(y2-y1)/(x2-x1)---------> m=(5-8)/(3-4)----> m=-3/-1----> m=3

step 2
with m=3 and point B (3,5) find the equation of the line
y-y1=m*(x-x1)-----> y-5=3*(x-3)----> y-5=3x-9----> 3x-y=4

the answer is
<span>the equation in the form Ax+By=C is
</span> 3x-y=4

see the attached figure

Which is an equation in slope intercept form of the line that passes through (1, 3) and (2, 4)?​
Murrr4er [49]

Answer:

y = x + 2

Step-by-step explanation:

The slope-intercept equation is:

y = mx + b

First, you should use the point-slope formula to find the slope. Plug in the "x" and "y" values given from the points:

Point 1: (1,3)        Point 2: (2,4)

y₁ - y₂ = m(x₁ - x₂)               <--- Point-slope formula

(3 - 4) = m(1 - 2)                  <--- Plug in "x" and "y" values from points

-1 = -m                                <--- Simplify inside parentheses

1 = m                                  <--- Divide both sides by -1

Finally, use one of the points to solve for the y-intercept (b):

Point 1: (1,3)           m = 1

y = mx + b                       <--- Slope-intercept formula

3 = 1(1) + b                       <--- Plug in values from point and slope (m)

3 = 1 + b                          <--- Multiply slope and "x" value

2 = b                               <--- Subtract 1 from both sides

Since the slope = 1, it does not need to be included in the final formula. The final answer is:

y = x + 2

Write an algebraic expression to describe the combined number of posts for Jenny and Antonio after any given number of days
Charra [1.4K]
Suppose Jenny publishes X post per day, and Antonio publishes Y post per day.
So, the combined number of posts will be X+Y multiplied by the number of days.

For example, if the numbers of days is Z, Jenny and Antonio published Z(X+Y) posts.

<u>Given that</u> :

Diameter (d) = 18 cm

Pi (π) = 3.14

Radius (r) = d/2 = 18/2 = 9 cm

We know that volume of sphere is

Volume of Sphere = 4/3πr³

Volume = 4/3 × 3.14 × (9)³

Volume = 4/3 × 3.14 × 729

Volume = 4 × 3.14 × 243

Volume = 12.56 × 243

Volume = 3052.08

<u>Hence, the volume is 3052.08 cm³</u>

The linear combination method is applied to a system of equations as shown.
tensa zangetsu [6.8K]

Answer:

(9,3)

Step-by-step explanation:

4(.25x + .5y = 3.75) → x + 2y = 15

(4x – 8y = 12) → x – 2y = 3

2x = 18

Divide both sides by 2

x = 9

Substitute x = 9 into  x + 2y = 15

9 + 2y = 15

Subtract 9 from both sides

2y = 6

Divide both sides by 2

y = 3

Solution

(9, 3)

What is 11/12 divided 2 5/8
lisov135 [29]

Answer:

2 2/21

Step-by-step explanation:

11/2 ÷ 2 5/8

= 11/2 ÷ 21/8

= 11/2 × 8/21

= 88/42

= 44/21

= 2 2/21

Hence 11/2÷2 5/8 is 2 2/21
