It’s the first one - 3x^2 - 3x+8 - 9/x+1
Answer:
1 Hour
250 + 150h = 500
Step-by-step explanation:
So, the fee for the meeting is 250. The hourly fee is 150. Let h equal the number of hours.
250 + 150h
If pablo has 500, then we cannot exceed that amount. So, our equation becomes
250 + 150h = 500
Subtract 250 from both sides
150h = 250
And divide by 50 on both sides. You get x = about 1.67. Since this is a question about time and money, you would round down to 1.
Answer:
175
Step-by-step explanation:
I would assume you are asking what 2 + 2 + 9 * 19, and that the image is merely advertisement and irrelevant info for the question.
Anyway, we are solving 2 + 2 + 9 * 19.
<u>PEMDAS: Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction:</u>
That is the order of operations. We can apply that in your equation.
Since multiplication comes before addition/subtraction, we are solving 9 * 19 first. That gives 171.
Now for addition:
2 + 2 + 171 = 4 + 171.
4 + 171 = 175.
Thus, our final answer is 175.
Answer:
a. False. A constant is a number on it's own, and 5 would be the coefficient of x. 8 would be the constant.
b. False. -6.5 would be the constant, since it's on its own. But actually, x would be carrying on a coefficient of 1. Letters are variables, not constants.
c. True.
Find the slope for the two lines and state that they are equal (condition for parallel lines)
Slope of line AB
[y2 - y1] / [x2 - x1]
Slope of line CD
[y4 - y3] / [x4 - x3]
Condition
[y2 - y1] / [x2 - x1] = [y4 - y3] / [x4 - x3]
