OK so it's quite easy In a graph it would be the point that touches the y axis. The point that intersects the y axis.

In an equation it would just be the never without the variable

for example

y = 5x+10

The 10 is the y intercept because it doesn't have any other variable next to it

When you want the x intercepts (x,0):. Set y=0 then solve for x

The total number of calories for 18 cups of milk is 1620 calories.
If two cups of milk is 180 calories then divide 180/2 to find the unit rate.
Then multiply 90 by the number of cups (18) and then you get the total number of calories for that many drinks.

6n+n+14=0 i need the math

Fofino [41]

Let's solve your equation step-by-step.6n+n+14=0

Step 1: Simplify both sides of the equation.6n+n+14=0Simplify: (Show steps)7n+14=0

Step 2: Subtract 14 from both sides.7n+14−14=0−147n=−14

Step 3: Divide both sides by 7.7n7=−147n=−2

Answer:n=−2

Find the radius of a circle having area 616cm square.

OLEGan [10]

Answer:

$\boxed{\sf Radius \ of \ circle = 14 \ cm}$

Given:

Area of circle = 616 cm²

To Find:

Radius of circle

Step-by-step explanation:

$\sf \implies Area \ of \ circle = \pi r^{2} \\ \\ \sf \implies 616 = \frac{22}{7} \times {r}^{2} \\ \\ \sf \implies 616 \times \frac{7}{22} = {r}^{2} \\ \\ \sf \implies 28 \times \cancel{22} \times \frac{7} { \cancel{22}} = {r}^{2} \\ \\ \sf \implies 28 \times 7 = {r}^{2} \\ \\ \sf \implies 196 = {r}^{2} \\ \\ \sf \implies {r}^{2} = 196 \\ \\ \sf \implies r = \sqrt{196} \\ \\ \sf \implies r = \sqrt{ {14}^{2} } \\ \\ \sf \implies r = 14 \: cm$
