on Saturday Leo and his brother drove into town to visit their mom Leo is trying to remember how much he spent on gas and tolls

tolls were a dollar $1.75 each and he also spent $28 at the gas station to fill up what are the terms and their factors and coefficients of the algebraic expression that represents the total cost of gas and tolls

Let t be the number of tolls they crossed.

Amount they spent at each toll = $1.75.

Amount they spent at gas station = $28.

Let C be the total amount they spent on gas and tolls.

If they crossed 1 toll, then

C = 28 + 1.75(1).

If they crossed 3 tolls, then,

C = 28 + 1.75(3)

If they crossed t tolls, then,

C = 28 + 1.75t

Here, the terms are 28 and 1.75t and the factors are 1.75 and t.

What is the equation of a line that has a slope of -2/3 and a x-intercept of -3?
garri49 [273]

For this case we have that, by definition, the equation of a line in the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cutting point with the y axis

We have, according to the statement data that:

m = - \frac {2} {3}

So, the equation is of the form:

y = - \frac {2} {3} x + b

We also have that the line intersects the "x" axis at -3, that is, the line passes through the point (x, y): (- 3,0)

We substitute to find "b":

0 = -\frac {2} {3} (- 3) + b\\0 = -2 + b\\b = 2

Finally, the equation is of the form:

y = - \frac {2} {3} x + 2

Answer:

y = - \frac {2} {3} x + 2

I. Need help !!!!!!
mestny [16]
Hey there!

To find the discriminant of an equation, you first need to identify the A, B, and C of your equation. You can do this by comparing your equation to the standard form. 

Standard Form: ax² + bx + c
Equation: 3x² – 10x + 2

If you add 2 to both sides, you can get everything on one side and you can assure that all of your numbers are accurate. 

A will be equal to 3, B will be –10, and C will be 2. 

Now, you need to plug in those numbers into the discriminant equation:

b² – 4ac

If your discriminant is 0, there is one rational solution. If it's a positive perfect square, there are 2 rational solutions. If it's a positive non–perfect square, there will be 2 irrational solutions, and if it's a negative number, there will be 2 complex solutions. 

Hope this helped you out! :-)

6. If the set A = {-2, 1, 3), then the set A is a subset of the set of?​
NeX [460]

Answer:

Step-by-step explanation:

We could invent set B:  {-2, 1, 3, 5, 6, 10} and then correctly state tht set A is a subset of B, because {-2, 1, 3} is also found in A.

Solve for x and then find the measure of B
s344n2d4d5 [400]

Answer:

x = 9      Angle B = 40 degrees

Step-by-step explanation:

Angles A and B are congruent, so the equation are the same

5x - 5 = 3x + 13

-3x       - 3x              Subtract 3x from both sides

2x - 5 = 13

    + 5   +5                Add 5 to both sides

2x = 18                      Divide both sides by 2

x = 9

Plug this into the equation for angle B

B = 3(9) + 13      Multiply

B = 27 + 13        Add

B = 40
