Write the equation of a line in slope intercept form given;<br> (6,-3), (0, 5)
olganol [36]

Answer:

y=(-4/3)x+5

Step-by-step explanation:

so you want to start by using y=mx+b

step one: find the slope (remember m is the slope in this)

m= \frac{y2-y1}{x2-x1}

m= \frac{5+3}{0-6}

m= \frac{8}{-6}

m= - \frac{4}{3\\}

step two: insert the value we found for m into the equation and take one of the given points and insert the x and y into the equation (im using (0,5)) and solve for b.

y=mx+b

5= -4/3(0)+b

5=b

step three: rewrite y=mx+b with the values we found for m and for b

y=(-4/3)x+5

primo car rental agency charges $33 per day plus $0.20 per mile. ultimo car rental agency charges $17 per day plus $0.85 per mil
belka [17]

Let's assume m represent the mileage of the car.

Given that, Primo car rental agency charges $33 per day plus $0.20 per mile.

So, the total charge for this agency = 33 + 0.20m.

Similarly total charge of the ultimo car = 17 + 0.85m.

Now we need to find the daily mileage for which the ultimo charge is four times the primo charge . So, we can set up an equation as following:

17 + 0.85m = 4 *( 33 + 0.20m )

17 + 0.85m = 132 + 0.80m By distribution property.

17 + 0.85m -0.80m = 132 + 0.80m -0.80m Subtract 0.80m from each sides.

17 + 0.05m = 132

17 + 0.05m - 17 = 132 - 17 Subtract 17 from each sides.

0.05m = 115

\frac{0.05m}{0.05} =\frac{115}{0.05} Divide each by 0.05.

So, m = 2300

Hence, the daily mileage is 2300 miles.

Hope this helps you!

110 freshmen participated in sports or clubs or both. 55 are involved in sports and 68 are involved in clubs. How many students
Varvara68 [4.7K]

Answer: 42

Step-by-step explanation:

Let A represents the number of freshmen participated in sports and B represents the number of  freshmen participated in clubs.

Then , we have given that

n(A)=55\\\\n(B)=68\\\\n(A\cup B)=110

Using formula

n(A\cup B)=n(A)+n(B)-n(A\cap B)

We have,

110=55+68-n(A\cap B)\\\\\Rightarrow\ n(A\cap B)=123-110=13

Now, the number of students are involved in just sports is given by :-

n(A)-n(A\cap B)=55-13=42

Hence, 42 students are involved in just sports.
