Answer: y = 3x+2

Step-by-step explanation:

slope = (62-32)/(20-10)

point-slope form -> y - 32 = 3(x -10)

y = 3x+2

2. Find the slope, or rate of change, represented in the table below. x -1 0 1 2 3 У -8 3 14 25 36

Answer:

Step-by-step explanation:

slope is change in y over change in x. so, if x is increasing by one every time and y is increasing by 11, then the slope is 11/1, which we write as 11.

How many even 2-digit positive integers can be written using the numbers 2, 4, 5, and 8?

BartSMP [9]

Answer:

Step-by-step explanation:

To have an even integer the number's endian has to be an even number. Consider the 2-digit positive number like _ _ and place the number of possible options out of four total options in each blank space. We have 3 even options, so we can fill the endian blank like this _ 3

Since the first digit can be any number, therefor, we have 4 options for the first blank space 4 3. Just multiply the two numbers and you have the answer.

22, 24, 28, 42, 44, 48, 52, 54, 58, 82, 84, 88

Someone pls help:( I can’t

max2010maxim [7]

Answer:

x = 8 is the answer :)

Step-by-step explanation:

Slope(m) = -2/5

slope is passing through the points: (x,1) and (3,3)

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

$m = \frac{3-1}{3-x}$

$m=\frac{2}{3-x}$

$-\frac{2}{5} =\frac{2}{3-x}$

-2(3 - x) = 2 × 5

-6 + 2x = 10

2x = 10 + 6

2x = 16

x = 8

Hopefully, this answer helped :)

The following formula relates 3 equantities: force(F),mass(m),and acceleration(a)

weqwewe [10]

We know, Force = mass × acceleration

( i ) :

Given,
Force = 25 units
Mass = 10 units
Acceleration = ?

Solution,

Applying the formula of force,
➡ Force = mass × Acceleration

⏩ 25 = 10 × acceleration

⏩ 25 / 10 =acceleration

⏩ 2.5 units = acceleration

( ii ) :

Given,
Force = 25 units
Acceleration = 5 units
Mass =?

Solution :

Applying formula,
➡ Force = mass × acceleration

⏩ 25 = 5 × mass

⏩ 25 / 5 = mass

⏩ 5 units = mass
