Answer:

5) -5/4    ||  6) -1/2  ||  7)  -3/4  ||  8) -5/3

Explanation:

Using the formula:

y = mx + b..............................where m is the slope and b is the y intercept.

5) y = -5/4 x + 3

comparing the equation, we know -5/4 is the slope.

6) y = -1/2 x + 2

comparing the equation, we know -1/2 is the slope.

7) y = -3/4 x

comparing the equation, we know -3/4 is the slope.

8) y = -5/3 x + 5

comparing the equation, we know -5/3 is the slope.

Answer:

x=18 is the correct answer

Answer:

y = -1.2x + 30

x = 22

x = 15

Step-by-step explanation:

Part A

Initially, Devin has $30.  Then every time he rides the bus, $1.20 is taken away:  y = 30 - 1.2x

Therefore, in slope-intercept form:  y = -1.2x + 30

If he has $3.60 on his card, then y = 3.60, so substitute this into the above equation and solve for x:

                                                  3.60 = -1.2x + 30

subtract 30 from both sides:  -26.4 = -1.2x

divide both sides by -1.2:             22 = x

Therefore Devin has ridden the bus 22 times if he has $3.60 on his card.

Part B

Rebecca:  y = -1.4x + 33

To determine how many rides on the bus Devin and Rebecca would need to take to have the same amount of value of their bus card, simply equate the equations and solve for x:

                                          Rebecca = Devin

                                                       y = y

                                         -1.4x + 33 = 30 - 1.2x

subtract 33 from both sides:   -1.4x = -3 - 1.2x

Add 1.2x to both sides:           -0.2x = -3

Divide both sides by -0.2:             x = 15

Therefore, Devin and Rebecca would both have to take 15 rides on the bus to have the same amount of value of their bus card.

30 + 18x = 6(5+3x)

Step-by-step explanation:

for this all you have to do is distribute the 6 by doing 6 x  5 = 30 and  

6 x 3 = 13 and then you just have to add them together to get

30 + 18x = 30 +18x

Answer:

300+0.75x=y

Step-by-step explanation:

x(the number of large coffes ordered)

y(the total donation)

Answer:

y=0.75x+300

Step-by-step explanation:

So for this problem, I'm going to put it in slope-intercept form (only because it makes the most sense to me, plus if you need to graph it, this will be helpful)

So Jan is donating $300 first. So whatever you need to do, you need to add 300 afterwards to account for that donation. But then, Jan is going to donate $0.75 for every large coffee ordered. This is means it is a dependent variable. The amount is dependent on how many large coffees ordered.

Say, for example, there were 15 large coffees ordered. You should multiply 0.75*15, which will give you a product of 11.25. So for all the coffees ordered, Jan will donate a total of $11.25 (which isn't a lot, but that's okay). But that isn't ALL the money that Jan donated because, as stated before, Jan is going to donate $300 regardless of how many coffees ordered. So the total amount of money donated is $311.25

Hope this helps!

Answer:

  45°

Step-by-step explanation:

The acute angles of a right triangle are complementary. The base angles of an isosceles triangle are congruent. If x is the measure of the base angles, this requires ...

  x = 90-x . . . . . the base angle is congruent to the other base angle

  2x = 90 . . . . . add x

  x = 90/2 = 45 . . . . divide by 2

The measure of a base angle of an isosceles right triangle is 45°.
