Answer:

y-30 = 3(x-1)

Step-by-step explanation:

Point-slope form of an equation is

y-y1 = m(x-x1) where (x1,y1 ) is a point and m is the slope

We know on day 1 they exercised 30 minutes (1,30) where x is the number of days and y is the minutes. The rate increased 3 minutes each day so m = 3

y-30 = 3(x-1)

A clothing
store offers a rewards program in which customers earn points by making purchases at the
store. Every item bought is worth 8 points, and customers earn 20 points when they sign up. Write an
equation for the function that gives the number of points based on the number of items bought. How
many points will a customer have after making 16 purchases?

Answers

Answer:

Equation for the function: y=8x+20

Step-by-step explanation:

8 represents points per item/rate of change

20 represents the y intercept or what the person gains in the beginning that doesn't change.

8(16)+20

128+20

=148

After making 16 purchases the person will have 148 points.

Answer:

247 horses

Explanation:

Key Info: 225 horses this year and this is 22 horses fewer than last year

We know that fewer means it is subtraction, but since we don't know how many horses were there last year we do the opposite which is addition.

In this case the inverse or opposite equation is 225 + 22 = h.

After adding this up you should get 247 horses were there last year.

There are 247 horse counts last year.

What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

A rancher counted 225 horses on the range, which is 22 fewer than last

year.

let h be number of horses counted last year.

Then, the number of horses count

h - 22 = 225

add 22 on both side

h -22 + 22= 225 + 22

h = 247

Hence, there are 247 horse counts last year.

Suppose that 13 inches of wire costs 39 cents. At the same rate, how many inches of wire can be bought for 21 cents?

Answers

Answer:

63 cents

Step-by-step explanation:

Suppose that 13 inches of wire costs 39 cents. At the same rate, how many inches of wire can be bought for 21 cents?

0.39/13 = 0.03in

o.03 X 21 = 0.63

so 63 cents check

63/21 should equal 39/13

63/21 = 39/13

63 X 13 = 39 X21

21 X 3 X 13 = 3 X 13 X 21

yes

21 X 3 X 13 = 21 X 3 X 13
