Answer:

y = 2x - 3

Step-by-step explanation:

Since the equation for the line y = 2x + 5 is already in slope-intercept form (y = mx + b), the slope (m) is 2. A parallel line will have the same slope. Now use point-slope formula to find an equation for the parallel line including point (3,3). Point-slope formula is:

(y – y₁) = m(x – x₁), where m is the slope (2) and (x₁, y₁) is the point the line passes through (3,3).

Therefore:

(y – 3) = 2 (x – 3)

y – 3 = 2x – 6

y – 3 + 3 = 2x – 6 + 3

y = 2x - 3

the difference of two numbers is 20 the larger of the two number is 2 more than twice the smaller. what are the two numbers?

faltersainse [42]

Answer:

x = 38

x = 18

Step-by-step explanation:

Let one number = x

Let the second number = y

x - y = 20

x must be the larger of the two numbers

x = 2y + 2 Put this equation into the equation above

2y + 2 - y = 20 Combine

y + 2 = 20 Subtract 2 from both sides

y = 20 - 2

y = 18

x - 18 = 20 Add 18 to both sides

x = 38

Four times the number of coins in my pocket plus five more is twenty-nine. Write an equation for the number of coins in my pocke

Lynna [10]

There are six coins already in pocket, but let’s say we don’t know it.

We would figure it out by reversing the problem. Let’s start with twenty-nine. We would subtract 5, because we are reversing. Now we have 24. Now, let’s divide by four. We would get 6.

A simpler answer would be 29 - 5 [divided by] 4 = [answer]

Answer: a. the slope is -2/5 and the y-intercept is -1/3

Step-by-step explanation:

Find the slope by finding the difference in x-values divided by the difference in y-values

(1/4 ,-13/30) and (-3/4, -1/30) are useful values

-13/30 --1/30 = -12/30 = -2/5 is the rise

-1/4 - -3/4 = 1 is the run (-2/5)/1 Division by 1 leaves the original numerator)

the slope is -2/5

To find the y intrcept, substitute the y and x values from any given coordinate into the slope intercept form and solve for b

y= mx + b

-3/5 = (-2/5)(2/3) + b

-9/15 + 4/15 = b

-5/15 = b

-1/3 = b This is the y-intercept
