So we start by replacing x with 1 so 15=3(2•1+4)-3
we start with the inside of the para thesis so multiply 2•1 which gives us 2 and we add 4 which gives us 6
now we have 15=3(6)-3
we multiply the 3 and 6 and we get 18
Now we have 15=18-3 so we subtract 18-3 and we get 15
15=15 is the product

Groceries cost $75. The tax is 5%. Will you have enough money to pay for the groceries if you have $80. Please explain.
Nastasia [14]

Answer:

Yes, we have enough money to pay for the groceries.

Step-by-step explanation:

We are given that Groceries cost $75. The tax rate is 5%.

We have to check that will the amount of $80 enough to pay for the groceries or not.

<em>For this we will firstly calculate the total cost of groceries after applying tax rate of 5% on groceries. </em>

Cost of groceries after applying tax rate is given by;

Since we know that by applying a tax on any item it's cost gets increased.

So, <u>Cost of groceries after tax</u> = Cost of groceries before tax + Amount of tax      

Amount of tax = Tax rate \times Cost of groceries

                        = 5% \times $75

                        = \frac{5}{100} \times 75 = $3.75

So, Cost of groceries after tax = $75 + $3.75 = $78.75

Since we have an amount of $80 with us which means that we are able to buy the groceries after giving tax on it as $78.75 < $80.

Therefore, yes we have enough money to pay for the groceries.

Write an equation in slope intercept and form of the line through point(6,-1)with slope m=4
aniked [119]

To solve this problem, we must first remember that slope-intercept form is y=mx + b, where the variable m represents the slope of the line and the variable b represents the y-intercept of the equation.

To begin, we can take this form and substitute in the slope for the variable m.

y = mx + b

y = 4x + b

Next, because we weren't given the y-intercept, we can find it by substituting the value of 6 for x and the value of -1 for y (these values came from the ordered pair that we were given in this problem).

-1 = 4(6) + b

After that, we can begin to simplify and solve for the variable b by computing the multiplication on the right side of the equation.

-1 = 24 + b

Next, we should subtract 24 from the right side of the equation in order to get the variable b alone.

-25 = b

Now, if we substitute in this value for the variable b in our equation with the slope, we get:

y = 4x - 25

Therefore, your answer is y = 4x - 25.

Hope this helps!
