Answer:
0.2
Step-by-step explanation:
The formula is right there, Mr. President.
All you need to do is write the numbers you know into the correct
places in the formula, and then find the value of the fraction.
The formula: Density = (mass) / (volume)
You know:
mass = 67.5 grams
volume = 5 ml
Write them in the correct places in the formula:
Density = (67.5 grams) / (5 ml)
= (67.5 / 5) (grams / ml)
= 13.5 grams/ml
Answer: y = 2x + 20
Step-by-step explanation: slope, y2 - y1/x2 - x1
replace it with these numbers 120 - 60/50 - 20=60/30
than,simplified it we get 2/1. so, now we have the slope of our equation
y = 2x + b. but we still have b (or where the y intersects.) now are slope we have to change it to 1/2 because we are going backwards. So multiply 60 by .5, Thus will give us 30
Now we have y = 2x + 30, But that's not one of your answer,
So y = 2x + 20 cant be -20 because this is a positive y intersect and We know it is a slope of 2.
Therefore the answer is : y = 2x + 20
ALSO I got it correct on the test!!
The graph is turned upside down. A negative parabola points down rather than up.
Answer:
It allows to to know y-intercept formula which is used to graph a line.
Step-by-step explanation:
Y-intercept formula:
y=mx+b
M: slope (keep in fraction if it is fraction, to help you graph)
B: y-interecept
