Answer:

The expression for the other number is (n-1)

Step-by-step explanation:

we know that

The difference between two consecutive number is equal to 1

Let

x ----> the smaller of two consecutive number

n ----> the larger of two consecutive numbers

we have that

n-x=1

Solve for x

x=n-1

therefore

The expression for the other number is (n-1)

Solve each system of equations using matrices.<br> -2x = -6y + 8<br> 2y = x + 1
Elden [556K]

Answer:    1.) x - 2y = 4 , add 2y to both sides. ---> answer is, X = 2y + 4

2.) 2x - 6y = 8, Add 6y to both sides, then divide both sides by 2. --> answer is, X = 3y + 4

The graph of a proportional relationship contains the point (-30, 18)
Elena L [17]

Answer:

k=-\frac{3}{5}

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form k=\frac{y}{x} or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

we have the point (-30,18)

so

x=-30, y=18

Find the value of k

k=\frac{y}{x}

substitute

k=\frac{18}{-30}

Simplify

Divide by 6 both numerator and denominator

k=-\frac{3}{5}

According to the scores on the last math test, 80%, or 20, of the students in the class received an A. Find the number of studen
Sladkaya [172]
80% is the same as 4/5, so 4/5 of the class= 20. That means that if there was a picture, 4 parts would be shaded, and 1 would not. 1/4 of 20 is 5, so 1 part= 5 people. 5 x 5 = 25. 25 is the answer. :)

Eliminate the parameter.<br><br><br>x = 5t, y = t + 8 (2 points)
maxonik [38]

Answer: y = \frac{1}{5}x + 8

Step-by-step explanation:

       This is asking us to remove the parameter. In other words, we want an equation with only the relation between x and y, so we need to remove the t. There are a few ways to do this, but I am going to set one equation equal to t and then plug it into the next one.

     Given:

x = 5t

    Divide both sides of the equation by 5:

t = \frac{1}{5}x

     -

    Given:

y = t + 8

    Plug in:

y = (\frac{1}{5}x) + 8

    Answer:

y = \frac{1}{5}x + 8
