Step-by-step explanation:
Answer:
y + 4 = 2(x+1)
Step-by-step explanation:
Begin by calculating the slope m using the slope formula. Then substitute m and (-1,-4) into the point slope form. The point slope form of the line is .
Slope Formula:
Substitute m = 2 and (-1,-4).
Answer:
2x + 5
Step-by-step explanation:
Let x represent the number
Twice the number will be represented by 2x, since that multiplies the number by 2
Then, add 5 to this:
2x + 5
So, 2x + 5 is the expression that will represent this situation
Answer:
0.00212
Step-by-step explanation:
The ratio of the areas is the ratio of the squares of the sides ( which is 10:15 or 2:3) so the answer is
2^2 : 3^2 = 4:9.
The ratio of the perimeters = ratio of corresponding side = 2:3.
