y=2x+1
(2x) is the slope because the slope is going up the slope will be positive and the (1) is the y intercept which means where the slope crosses the vertical line
Answer:
B=-9
Step-by-step explanation:
Technically, I didn't solve it. I used an algebra calculator online called m a t h w a y. It helps a lot but if you really need to know how to solve it on pencil and paper I cannot help you.
I had to space out the website so it let me submit this answer btw
The value of
a boat after t years is represented by the function f(t)=11,200(0.93)t
The function has the
parts of the initial value of the boat
The percent of increase or decrease of the with time
And how in how many times
The 11,200 represents the intial value of the boat
Answer:
2 students failed the test.
Step-by-step explanation:
There are 40 students and 95% passed. 95% is also equal to 0.95. Since we are looking for the students who failed, subtract 1.00 - 0.95. You get 0.05. The percentage of students who failed is 5%. Multiply 0.05 times 40 to get 2. This is the amount of students who failed.
Answer:
(x, y) = (3, 5)
Step-by-step explanation:
Solving by elimination here again, there are 2 good options available. Either multiply the whole bottom equation by -1 to cancel the x, or by 2 to cancel the y. I'll do the latter:
Add from top to bottom:
Now, with the value of x, solve for y in either of the equations. I'll choose the second one here:
(x, y) = (3, 5)
