<span>Let’s assume the number of problems as P Student did his homework = (3/5) P + 8 Father did the homework = (1/5) P + 7 So the sum of the both equations is equal to P => (3/5) P + 8 + (1/5) P + 7 = P => (4/5) P + 15 = P => 4P + 75 = 5P => P = 75 Problems they solve together are 75 problems.</span>

Last season he scored 179 touchdowns. This season he scored 253 touchdowns.
nydimaria [60]
Given,
Previous Season touchdowns scores = 179
Current Season touchdowns scores = 253
Here,
Increased touchdowns scores = 253 - 179 = 74
Now,
Percent increment = (increased/previous)*100 = (74/179)*100 = 41.34%
Hence, the required answer is 41% ( nearest round off percent)

What is an equation of a line in point slope form that passes through the points (7,-8) and (-4,6)?
maw [93]

y=kx+b

for (7,-8): -8=7k+b. (function 1)

for (-4,6): 6=-4k+b (function 2)

Use function 2 - function 1

we get: 14=-11k

k=-14/11------>slope is -14/11

Now we know that first two options are wrong since they have the wrong slope for the function.

Plus -14/11 back to function 1/ or 2. Both are correct and can give you the answer. In this case I would plug it back to function 2.

6=14*4/11+b

b=66/11-56/11

b=10/11

We get y=-14/11x+10/11

subtract both side by 6.

y-6=-14/11x+10/11-66/11

y-6=-14/11x-56/11

y-6=-14/11(x+4)

So C is correct
