Slope intercept form is y = ax + b, where a is equal to the slope value, and b is equal to the y-intercept.

You have both the slope and y-intercept, which means that all you need to do is plug in the numbers to the equation in order to get your answer!

Let's plug in -7 for a, which gives you y = -7x + b.

Next, we'll plug in the y-intercept, which gives you y = -7x + 9.

Hope this helps!! :)

A restaurant owner made a list of the number of meals ordered last night. She found that 42 people ordered chicken Parmesan, 39

Answer:

29/110

Step-by-step explanation:

There are a total of 110 orders at the restaurant, so that will serve as the denominator. There are 29 meatballs, so that will be the numerator. Combine the two and you get 29/110. Experimental probability is what happens in the experiment like this question. Theoretical probability is "real math" as in 1/3.

In fact, this problem belongs to the chemistry section. Recall that many other sciences require mathematical calculations. The problem will belong to Mathematics only if no knowledge of other sciences are required to solve the problem.

Solubility for the given substances is measured in grams per 100 g of water at a particular temperature (20 deg.C).
This means that the mass (assumed to be the solute) will not change the solubility, just the minimum quantity of solvent (water) will.
Thus the solubility of sodium chloride will remain L=36 g/100g H2O for any quantity of solute. Similarly, the solubility of lead nitrate will remain as K=54 g/100 g H2O.

The reason that they remain constant is because the quantity of solvent (water) is fixed at 100 g. Varying amount of solute will affect the quantity of solvent required, but not the solubility.
I'll leave it to you to calculate the difference between K & L.

False.
y= 3(1)+1= 4
y= 3(2)+1=7 not 5
y= 3(3)+1=10 not 6

Written as a simplified polynomial in standard form, what is the result when (x-8)^2

neonofarm [45]

Answer:

26x-67-x²

Step-by-step explanation:

We are given

$(10x - 3) - (x - 8) {}^{2}$

Expanding (x-8)²=x²-16x+64

10x-3-(x²-16x+64)

10x-3-x²+16x-64

26x-67-x²
