Answer:
336
Step-by-step explanation:
Which of the following could be the graph of the line y = 3x - 2?
You didn't give a graph but I will visualize what it looks like for you.
The line is going through (0,-2) because that is the y-intercept.
The line has a slope of 3.
So, the line goes through:
(1,1)
(2,4)
(3,7)
(4,10)
(5,13)
Since there is no picture provided, I can't give you the answer, but I can help you solve it.
To solve this you have to first look at the b part of the formula y=mx+b, so -2.
Then, you can find -2 on the y-axis (the vertical axis)
and then you could move upwards 3 spaces, then right 1 space.
You would do this as the slope is 3/1 (the mx part of the equation).
Finally, you continue to move up 3, and right 1 until there are enough points on the graph to make a line, and that will help you see what graph is correct.
It should look something like this:
Return to the original problem. PEMDAS says to multiply before adding. But could you have performed a different operation and still have gotten a correct answer? Which one? Explain.
(4x2 + 8x + 15) + (x2 − x − 27) − (x + 5)(x − 7)
Answer:
no
Step-by-step explanation:
Because PEMDAS is something you MUST follow no matter WHAT!!!!!!!!

The graph shows the total cost of a zoo membership for family. which equation can be used to find the total cost y for any number of family members X?
A. y= 10x
B. y= 25x
C. y= 10x +25
D. y= 25x +10
Answer:
the answer is c
Step-by-step explanation:
cause math
Answer:
Answer is C. y = 10x + 25
Step-by-step explanation:
This equation is in the form y = mx + b
we all know b is the y-intercept (where the line passes y axis)
When we look at the graph, we see that the line passes through y-axis at 25 which means our b is 25.
If we plug 25 in place of b in y = mx + b, C is the only option that makes sense

James wants to compete in the international speed texting competition next year where participants compete on text speed and accuracy. James's current text speed is 2 characters per second. James has found that his texting speed is increasing at a rate of ½ a character per second for each month that he practices.
Complete question :
James wants to compete in the international speed texting competition next year where participants compete on text speed and accuracy. James’s current text speed is 2 characters per second. James has found that his texting speed increases at a rate of 1⁄2 a character per second for each month that he practices.
1. a. What is James’s new texting speed if he practices for only 1 month? __________
b. What is James’s new texting speed if he practices for 2 months? ____________
c. What is his new texting speed if he practices for 3 months? _____________
d. Write an algebraic equation that gives James’s texting speed s for m months of
practice.
Answer:
2 1/2 ; 3, 3 1/2 ; s = 2 + 1/2m
Step-by-step explanation:
Given that :
Speed = 2 characters per second
Rate of change = 1/2 character per second increase per month
New texting speed after 1 month :
Initial speed + (change per month * number of months)
2 + 1/2 * 1
= 2 1/2 or 2.5
After 2 months :
Initial speed + (change per month * number of months)
2 + (1/2 * 2)
2 + 1
= 3 characters per second :
After 3 months :
Initial speed + (change per month * number of months)
2 + 1/2 * 3
= 2 + 1.5
= 3.5
For the algebraic equation :
New texting speed, s
Number of months, m
Initial speed + (change per month * number of months)
s = 2 + 1/2 * m
s = 2 + 1/2m
y=4x-16. Please Show work
Answer: x=4
Step-by-step explanation:
Step 1. turn you y into a 0
0=4x-16
Step 2. get x alone
a.
0 = 4x -16
+16 +16
*what you do to one side of the equal sign you must to the other.
b.
0 + 16 = 4x
(divide by 4) 16 = 4x (divide by 4)
*divide by 4 to get rid of the 4 next to the x, remeber to do both sides of the equal sign
4 = x
The number of people y (in millions) who have a driver's license can be estimated by the linear equation y=2.3x+190, where x is the number of years after 2000.
y=2.3x+190
y= 95.
hope it's help

Step-by-step explanation:
1) a. y = -5x +50
b. y = 5
2) a. y = 2.5x +5
b. x = 10
3) a. y = -10x + 50
b. y = 10
help! is this correct?
Answer:
D) 13
Step-by-step explanation:
I'm going to assume 120 is a vertical angle so:
x + 47 + 120 = 180
x + 167 = 180
x = 180 - 167
x = 13
Guys Please solve this.
Answer:
y=-⅔+5
Step-by-step explanation:
using the slope formula we can figure out the slope is -4/6
using point slope formula (y-y1=m(x-x1))
y-7=-4/6(x--3)
y-7=-4/6x-2
y=-4/6x+5
Answer:
y=-3x-24
Step-by-step explanation:
(-3,7) (3,-11)
-11-7 = -18
3-(-3)= 6
-18/6= -3
y=-3x+?
b= y-3x
b= -3-3*(7)
b= -3 - 21
b= -24
Round 94584 to the nearest hundreds
Answer:
94600
Step-by-step explanation:
A hundred has 2 zeroes. To round a number to the nearest hundreds, just look at the last 2 digits (84). If it is 5 or bigger, add 1 digit (as I did in this exercise) and so it becomes 94600.

Jorge is building a circular stage for an upcoming concert. The stage needs to have an area of at
least 200 square meters to fit the performers. What is the smallest radius that the stage could have? Explain your reasoning,
Answer:
The smallest radius that the stage could have is 7.97 m.
Step-by-step explanation:
The stage needs to have an area of at least 200 square meters to fit the performers.
For a circle, the area is given by :
[tex]A=\pi r^2[/tex]
such that,
[tex]\pi r^2=200\\\\r=\sqrt{\dfrac{200}{\pi}} \\\\r=7.97\ m[/tex]
So, the smallest radius that the stage could have is 7.97 m.
