So for each of the graphs, you basically just have to fill out slope form, which is y=my+b. And to make this equation, you need to find each variable.

First, find the slope. To calculate slope, count the rise (how many units up or down) the line goes from any point to the next immediate point, then the run (how many units left or right.) This should leave you with a fraction, rise/run. For example, on number 3, from labeled points (-5, -4) to (5,2) (double check cause it’s hard to see on my phone, but i think those are the points on 1??) it rises 6 units (-4 to 2) and runs 10 units (-5 to 5). This gives you your rise/run fraction, which is 6/10, simplified to 3/5.

So the slope fills out the m part of the equation. For 3, we found that slope is 3/5, and that fits into the m variable of the slope equation.

This makes it y=3/5x+b.

The last (and considerably less confusing) step is to find b. b is the y-intercept, which is just the point in the graph where the line crosses the y-axis and x=0. On 3, this would be (0,-1) or just -1.

So fill -1 into the b slot of the equation, and you get y=3/5x-1. And thats it!!

Let me know if you still need help on any of the other problems, but I hoped this helped to clear it up!! :)

What is 7 over 12 / 5 over 9?<br><br><br> Answer truthfully, please!
attashe74 [19]

In math, "over" and "/" and "÷" mean the same thing. The expression you have written is

... 7/12/5/9 = 7/540

It seems possible you may want the ratio of two fractions to be simplified. Perhaps you intend ...

... (7/12)/(5/9) = (7/12)×(9/5) = (7×9)/(12×5) = 63/60

... = 21/20 = 1 1/20

Dividing by anything is the same as multiplying by its reciprocal. This is a convenient fact when dividing by a fraction.

1. Find p(-3) if p(x) = 4x3 - 5x2 + 7x - 10
SVETLANKA909090 [29]

Answer:

1) -184

2) 13(m^{4}) ^{2}-3(m^{4})+4

Step-by-step explanation:

For problem number 1, Let's start by substituting all the x's for -3

So the equation will look like

p(-3)=4(-3)^{3}-5(-3)^{2}+7(-3)-10

Now, lets simplify by solving the exponents

First we'll do -3^{3} which equals -27

Now we'll do -3^{2} which equals 9

So now our equation looks like

p(-3)=4(-27)-5(9)+7(-3)-10

Now, we are going to multiply all these numbers

First 4(-27) which equals -108

Now -5(9) which equals -45

And finally 7(-3) which equals -21

Now our equation looks like

p(-3)= -108-45-21-10

Now we can solve

-108-45-21-10=-184

Which statement is true about the reflectional symmetry of a regular heptagon? Check all that apply
Slav-nsk [51]

Answa line of symmetry will connect a vertex and a midpoint of an opposite side

it has 7-fold symmetry.  


Step-by-step explanation:

A line of symmetry is a line that we can use to "fold" a figure in half. In order to do this, we will "fold" the figure from a vertex to the middle of the side opposite the vertex. Since there are 7 vertices, there will be 7 lines of reflection. i looked it up so i hope this helps you can thank
