A=259.8 cm^2 is the correct answer
Answer:
2.9g/ml
Step-by-step explanation:
mass of the rock:130g
volume of the rock:45ml
d=m/v
d=130g/45ml
d=2.9g/ml
Answer:
The answer is y = 4x - 1
Step-by-step explanation:
First find two points on the line.
I will be using (-1, -5) & (1, 3).
Using the formula for slope, substitute in the values and solve:
y2-y1/x2-x1(This is the formula)
3--5/1--1(When using this formula, if y1 or x1 are negative, make them positive.)
3+5/1+1 or 8/2; which simplifies into 4/1.
So, the slope is 4/1.
Now we use point-slope form:
y - y1 = m(x-x1)
1. Substitute in the values.
y--5 = 4/1(x--1)
2. Simplify and distribute.
y + 5 = 4/1x + 4
3. Subtract 5 from both sides.
y = 4/1x - 1
4. Simplify.
y = 4x - 1

Step-by-step explanation:
Answer:
x^2 + 16x + 60 = 0
Step-by-step explanation:
Add 16x to both sides of the given equation. We get x^2 + 16x + 60 = 0.
