3 1/4 + 2 1/6

Step-by-step explanation:

So, let's use x2 - 3x - 28 as an example.

It's factors are (x - 7)(x + 4).

The roots are the x-values that make our expression equal 0. In order for x2 - 3x - 28 to equal 0, either of our factors need to equal 0, since 0 times anything is 0.

x2 - 3x - 28 = 0

(x - 7)(x + 4) = 0

x - 7 = 0

x = 7

(7 - 7)(7 + 4) = 0(11) = 0

x + 4 = 0

x = -4

(-4 - 7)(-4 + 4) = -11(0) = 0

That gives us two points on our graph, (7,0) and (-4,0). Where are those? On the x-axis! Thus, there are our x-intercepts.

By the way, for the future, along the x-axis, y = 0, so if you are asked for the x-intercepts (or roots), set y = 0 and solve for x.

Along the y-axis, x = 0, so if you are asked for the y-intercepts, set x = 0 and solve for y.

y = 02 - 3(0) - 28

y = -28

So, the y-intercept(s) of our same equation is y = -28, or (0,-28).

Boom.

Answer:

The x-intercepts are happen are when y = 0. If you tried to substitute y = 0 into a quadratic in the standard form you can not use traditional methods for solving for x.

Y=0 when looking for an x-intercept. Doing the factored form you are finding the x-intercepts. You always want the equation to equal 0 then factor out the equation till you get the numbers for the x-intercept.

Answer:

If the sales tax rate is 4%, the total amount of money that Rebecca will pay is equal to 190(1.04), or 197.60 dollars. This means, that the tax that Rebecca needs to pay is just 7.60 dollars.

Answer:

Consider a triangle ABC. Let the angle bisector of angle A intersect side BC at a point D between B and C. The angle bisector theorem states that the ratio of the length of the line segment BD to the length of segment CD is equal to the ratio of the length of side AB to the length of side .

Answer:

The slope will be the same for a straight line no matter which two points you pick as you know. All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.

Step-by-step explanation:

7 5/8 divided by 3/5 = 12.7083333333

Then you round down

Answer:

13 or 12.7

Step-by-step explanation:

You can fit 12.7083333334 of the fraction 3/5 inside of 7 5/8

It can be one of those because 12.7 is closer to 13 than to 12

Answer:

[tex]-\frac{6}{7}[/tex]

Step-by-step explanation:

[tex]-\frac{9}{14} + -\frac{3}{14}[/tex]

You can change the + - into a -,

you are basically figuring out: -9 - 3

which is -12!

Put that number as the numerator and 14 as a denominator

You get - 12 / 14, but you can still simplify it!

divide both of the numbers by 2...

So you end up getting: [tex]-\frac{6}{7}[/tex]

I think 15 cubic meters might be wrong tho

Step-by-step explanation:

Answer:

x = 3.25; y = 5.5; angle measures are (cw from bottom left): 96, 84, 96

Step-by-step explanation:

The two angles above the horizontal line form a linear pair, so they are supplementary. Their measures add to 180 deg. That let's you find the value of x.

28x - 7 + 24x + 18 = 180

52x + 11 = 180

52x = 169

x = 169/52

x = 3.25

Now use the lower left angle and the upper right angle. They are vertical angles, so they are congruent. That allows you to solve for y.

12y + 30 = 24x + 18

We know that x = 3.25.

12y + 30 = 24(3.25) + 18

12y + 30 = 78 + 18

12y = 66

y = 66/12

y = 5.5

I don't know what the problem is asking for since you don't show.

x = 3.25; y = 5.5; angle measures are (cw from bottom left): 96, 84, 96

Answer:

Step-by-step explanation:

The two top angles are supplementary.

Supplementary angles sum to 180 deg.

-------------------

Vertical angles have same measure.
