Step-by-step explanation:

which is the graph of y=3/4x -3

Answers

Answer:

A

Step-by-step explanation:

the formula y = mx + b is used here

lets look at the formula we were given

y = 3/4x -3

the first number we see, 3/4x is the slope of the line, where 1 = a 45 degree angle towards the NORTH EAST corner from 0, in this case it is less then 1 so it is less steep then 45 degrees, how i remember is that i can plot a point using the numbers the the fraction in reverse and connect a line from 0,0 to that line

4,3 is a point that a line with this slope would cross, but not this line, because it does NOT start at 0,0 , instead it crosses the y-axis lower because we took some of b away, in this case -3, so the line moves down 3, not changing the slope

i hope this makes sence and you are able to use it in multiple problems like this, comment this if you have any questions

take care m8

Lori has $450 in her bank account. She withdraws $20 a month for her gym membership. Construct a linear equation to model Lori’s bank balance for any given month.

Answers

Answer:

y=-20x+450

Step-by-step explanation:

Since Lori has 450$ initially, this can be modeled as our y-intercept of our function, or the b in y=mx+b. Since she's withdrawing 20$ a month to pay for the membership, she's losing 20$, which is why the 20 is negative in the equation. Let x be any amount of months, and y will be the balance of Lori's account at that month x.

Equation: y=20x+450

So first off the inequality sign has to be facing the 5 because that is the max amount of money he can spend on breakfast so we can immediately eliminate answer choices G and J

The reason the answer is not F is because your not adding b to 1.25

B is equal to the number of breakfasts Anthony can buy

Each breakfast cost $1.25 so it would be

5 is greater than or equal to 1.25b

Answer:

Step-by-step explanation:

b/c the breakfasts are $1.25  you would multiply how many he buys , by that cost,   soo

5 ≥ 1.25 * b

so he can buy 4 breakfasts  1.25 * 4 = 5

this works out fine for the math.  but, for one day .. no breakfast :(

Miya has some weekly chores to do at home. In one month, she washed 11 equal-sized loads of towels. She washed a total of 154 towels with t towels in each load.


Write a multiplication equation that can be used to find how many towels were in each load. Solve the equation you wrote. Explain how you solved your equation.

Answers

Answer:

14 towels per load

Step-by-step explanation:

Miya washed 11 equal sized loads of towels. She washed a total of 154 towels.

It is given that the variable, t, amount of towels are in each load.

Set the equation:

Amount of load x amount of towels per load = amount of towels in all

11 * t = 154

Isolate the variable, t. Note the equal sign, what you do to one side, you do to the other. Divide 11 from both sides:

(11t)/11 = (154)/11

t = 154/11

t = 14

14 towels per load is your answer.

~

Answer:

11x=154----> 14 towels for each of the 11 loads

Step-by-step explanation:

11x= 154

11x/11=154/11 Simplify the 154 with 11 on each side.

-Eliminate the number 11 and you should be left with x= 154/11.

-Divide

154÷11= 14
