Hi there!
To find the perpendicular slope you need to flip the fraction and change the sign. So 1/2=2/1 and tge original slope was positive, so the slope is -2. Now you sub in the point (-7,-4) in for x and y in the formula y=mx+b and solve for b (sub in 2 for m as well)
Y=mx+b
-4=-2*-7+b
-4=14+b
-4-14=b
B=-18
The equation is y=-2x-18
Hope this helps!
Answer: i have no idea
Step-by-step explanation:
The formula for volume of a rectangular prism is L x W x H
we can replace the letters with the information given and then solve for the missing letter:
240 cm^3 = 12 x 4 x H
multiply 12 and 4:
240 = 48 x H
now to solve for H divide both sides by 48:
h = 240/48
H = 5
the height is 5 cm
Answer:
380.832 pounds Approximately
Step-by-step explanation:
1 foot of water = 62.428 pounds (62.43)
6.1* 62.43= 380.832
1. identify the abc... ax^2+bx+c
2. write down all the factor pairs of C
3. identify which factor pairs from the previous step sums up to letter B
4.subsitute factor pairs in 2 binomials :)
