Write an equation in point-slope form of the line through point J(4, 2) with slope 3.

1 answer:

7 0

Point slope form is:

y − y $_{1}$ = m(x − x $_{1}$ )

Where x $_{1}$ and y $_{1}$ are two known coordinates and m is the slope.

Substitute (4,2) as x and y and 3 as m to find the point-slope form.

y − 2 = 3(x − 4)

Taking it to the next step would be to turn this into slope-intercept form, y=mx+b

y − 2 = 3(x − 4)
y − 2 = 3x − 12
y = 3x − 10

63 12/60 simplified

Andreas93 [3]

Your question is not clear, if you are asking: what is $63 \frac{12}{60}$ simplified? Then the answer is $63 \frac{1}{5}$ or $63.2$ .

If 63 is just the question number and you are asking, what is $\frac{12}{60}$ simplified. Then the answer is $\frac{1}{5}$ or $0.2$

You get this answer by finding the highest number that both the numerator and denominator are divisible by, and diving both numbers by that:

$\frac{12}{60} \div \frac{12}{12} = \frac{12 \div 12}{ 60 \div 12} = \frac{1}{5} = 0.2$

Number 2 is the problem i need help with

Reptile [31]

Answer:

2a) $180

2b) $1440

Step-by-step explanation:

2a) Basically Samuel works for 6 hours a day and earns 7.50 per hour, so you have to do 7.50 x 6 to see how much he earns per day (which in this case is $45). You then have to multiply $45 to 4 since he earns $45 per day and works 4 days per week (which is $180).

2b) After finding out how much he earns per week ($180 from the previous question), you then have to multiply $180 by 8 as $180 is the amount he earns per week and since he works for 8 weeks you have to multiply $180 by 8 (the answer is then $1440).

sorry if I'm not making sense, i tried :) good luck!
