Answer:

y=-2x+7

Step-by-step explanation:

Hi there!

The form of slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept

We are given the slope (-2) and a point (3,1)

We can immediately substitute -2 as the slope in the equation

y=-2x+b

Now we need to find b

Because the line will pass through the point (3,1), we can use it to solve for b

Substitute 3 as x and 1 as y

1=-2(3)+b

multiply

1=-6+b

add 6 to both sides to isolate b

7=b

Substitute 7 as b into the equation

The line is y=-2x+7

Hope this helps!

Answer:

The Answer is that there is less than 50 Liters of sauce in the 2 cans.

Step-by-step explanation:

Given: 2 Gallons of sauce

How many Liters in 2 gallons?

There are 3.7854 liters per gallon. Multiply to get the total liters in 2 gallons:

2 * 3.7854 = 7.5708 Liters.

7.5708 is less than 50 Liters. Therefore, there is less than 50 Liters in the 2 gallons of sauce.

Hope this helps!! Have an Awesome day!!! :-)

What is slope and how do you find it??

lions [1.4K]

the formula for slope is

$\frac{(y2-y1)}{(x2-x1)}$

so just replace y and x for the proper values

What is 25% of 24? What is 15% of 60? 9 is what percent of 72

JulsSmile [24]

Answer:

6.48

Step-by-step explanation:

this is the easiest way to solve for percentage:

$\frac{part}{whole} =\frac{part}{whole}$ Where all the percents (except 100) would go in part

and the whole number would go in whole

$\frac{25}{100} =\frac{?}{24}$ Then multiply 24 × 25 ÷ 100 = 6

$\frac{15}{100} =\frac{?}{60}$ Multiply 60 by 25 then divided by 100 = 9

Then for the last one 9 is what percent of 72

all we have to do is multiply 9 and then convert 72 into a decimal (0.72)

Then 9 × 0.72 = 6.48

A band expects to put 16 songs on their next CD. The band writes and records 50% more songs than they expect to put on the CD.

lara [203]

Answer:

12

Step-by-step explanation:

Add 50% of 16 to 16, 50% of 16 is 0.5 * 16 = 8, 16 + 8 = 24

Multiply 24 by 50%, or 0.5 to get 12
