Slope-intercept form: y = mx + b

m = slope

b = y-intercept

We need to find the y-intercept.

2 = 3(4) + b

2 = 12 + b

2 - 12 = 12 + b - 12

-10 = b

Now, fill in the equation.

y = 3x - 10

Hope This Helped! Good Luck!

Flora is making salsa for a party. Every 1 cup of chopped tomatoes makes 2 3/4 cups of salsa. She uses 1 2/3 cups of tomatoes. H
pogonyaev

Answer:

4\frac{7}{12} cups of Salsa.

Step-by-step explanation:

Flora is making Salsa for a party.

Every 1 cup of chopped tomatoes makes 2\frac{3}{4} = \frac{11}{4} cups of Salsa

She uses 1\frac{2}{3} = \frac{5}{3} cups of tomatoes

1\frac{2}{3} cups of tomatoes makes:

\frac{5}{3} ×  \frac{11}{4} ÷ 1 = \frac{55}{12} = 4\frac{7}{12} cups of Salsa.

Which of the following quadratic regression equations best fits the data shown below?
bazaltina [42]

Answer:

Step-by-step explanation:

In order to do this, you have to know how to use your calculator's regression equation function.  

First enter in the data. Hit "stat" then 1:Edit and enter all the x values into L1. After each value, hit enter. When you're done with the x list, arrow over to L2 and enter in all the y-values. If there are already values there you need to clear, arrow up to highlight L1, hit "clear", then "enter" and the values will disappear. Do that for both lists if you need to.

After the data is listed in L1 and L2, hit "stat" again and arrow over to "Calc". Hit 5:QuadReg. If you have a TI 83, your equation will be there for you. If you have a TI 84, you'll need to arrow down to "calculate" to get the equation. Regardless, the equation is

y=3.48x^2+1.22x+3.44, the last choice in your options.

Complete the identity
spin [16.1K]

Answer: cos(\pi-x)=-cos(x)

Step-by-step explanation:

We need to apply the following identity:

cos(A - B) = cos A*cos B + sinA*sin B

Then, applying this, you know that for cos(\pi-x):

cos(\pi-x)=cos(\pi)*cos(x)+sin(\pi)*sin(x)

We need to remember that:

cos(\pi)=-1 and sin(\pi)=0

Therefore, we need to substitute these values into cos(\pi-x)=cos(\pi)*cos(x)+sin(\pi)*sin(x).

Then, you get:

cos(\pi-x)=(-1)*cos(x)+0*sin(x)

cos(\pi-x)=-1cos(x)+0

cos(\pi-x)=-cos(x)
