Answer:-5/1

Step-by-step explanation:

down 5 and over 1

to get the slope, find a spot on the graph and then go 1 to the right and read how much the graph went up or down.
on 5) you see it did neither, so m=0
when the graph goes up, m is positive, when it goes down, m is negative.
so on graph 1, you have 2 dots.
you go 2 right, and 4 down. when the dots are not 1 apart (counting going right)  then divide by the steps you went right.
4 divided by 2 is 2.
-> graph went down, slope for 1) is m = -2

graph 2) you go 2 right and 2 up, 2/2 = 1. you went up, so m is positive and m = 1 for this graph.

3) is undefined because it doesn't go anywhere when you go right, it's 100% vertical

4) m = -5 because you went 1 right and 5 down

5) you go 6 right between the dots and 4 down. m is negative because it went down, not up. so m = -(4/6)

Answer:

24.359

Step-by-step explanation:

The height is opposite of the 77 so we are using sin. The length of the ladder is the hypotenuse.

sin(77°)=height/25     Set up equation sin=height/hypotenuse

25*sin(77°)=height     Multiply both sides by 25

25*.96437=height

height=24.359

Step-by-step explanation:

Exponent law:

        [tex]\sf a^m * a^n = a^{m+n}\\\\\dfrac{a^m}{a^n}=a^{m-n}[/tex]

In exponents multiplication, when bases are same add the powers.

In exponents division, if bases are same subtract the powers.

[tex]\sf \dfrac{7^8*7^3*7^4}{7^9*7^5}=\dfrac{7^{8+3+4}}{7^{9+5}}[/tex]

                  [tex]\sf =\dfrac{7^{15}}{7^{14}}\\\\=7^{15-14}\\\\=7^1\\\\=7[/tex]

Answer:

The two points used to find the slope:

[tex]x_1,y_1[/tex]: 2,30

[tex]y_1,y_2:[/tex] 4,10

Final equation: y = -10x + 50

Step-by-step explanation:

From a fellow 8th grader <3

First, let's review the slope of a line: y = mx + b

Where m is the slope, and b the y-intercept

Let's find the slope. To do this I will select 2 points from this graph, and using the slope formula I will calculate it

Slope formula: [tex]\frac{rise}{run} =\frac{change- in- y}{change-in-x} =\frac{y^2-y^1}{x^2-x^1}[/tex]

To get the most accurate answer, I will be using the 2 points given that are directly on the line:

1 = (2, 30)

2 = (4, 10)

Slope: [tex]\frac{10-30}{4-2} =\frac{-20}{2} =-10[/tex]

m = -10

It makes sense that it is a negative, since the graph continues downwards.

Let's update our equation: y = -10x + b

We can see that the line intersects the y-axis at y = 50

Plug this into our b-value:

y = -10x + 50

Now, I would recommend using a graphing calculator (like a TI-83) or an online one (like desmos) to double check this. I have attached a screenshot of this line on desmos. From there we can see if this line matches up with the one seen on your graph.

Our answer is:

The two points used to find the slope:

[tex]x_1,y_1[/tex]: 2,30

[tex]y_1,y_2:[/tex] 4,10

Final equation: y = -10x + 50

Please let me know if this helped you, and if this was the correct answer! If it is incorrect I will do my best to revise my answer.

Answer: y intercept is (0,50) and Slope is -10.

Final equation is y= -10x+50

Step-by-step explanation:

Y-intercept is at what point the line intercepts the y-axis. It intersects at (0,50) coordinate point as you can see.

Slope is change in y divided by the change in x. When you change x by 1, y changes by -10. So it is -10/1 = -10. Slope is -10.

Since we know y intercept and slope equation is y=-10x+50

Answer:

 $67,200

Step-by-step explanation:

The amount if interest is given by the formula ...

I = Prt

where P is the amount invested, r is the annual rate, and t is the number of years. Here, we want to find P when r = 0.05 and t = 1/2 such that I = 1680.

 P = I/(rt) = $1680/(0.05·0.5) = $1680/0.025

 P = $67,200

The amount invested was $67,200.

Step-by-step explanation:

The solution when Kaitlyn has at least five purses using signs and number is N ≥ 5

Equations and inequalities are both mathematical sentences formed by relating two expressions to each other.

When two expressions are equal, we use the equal sign ( = ). But when we are trying to compare two values or expressions, we use the inequality signs like greater than (>), less than (<), greater than or equal to ( ≥ ) and less than or equal to (≤)  

Given that: Kaitlyn has at least five purses

In order to solve this problem with signs and number, you will make use of the inequality that explains the situation:

Let the number of purses be N

Kaitlyn having at least five purses means she has 5 purses or more. Using inequality, the number of purses is greater than or equal to 5. Thus:

N ≥ 5

Therefore, the solution using signs and number is N ≥ 5

The equivalent expression using the distributive property is 6(7x + 2)

From the question, we have the following expression

42x + 12

Rewrite the given expression as follows

This is represented using

(42x + 12)

Factor out 2 from the expression

So, we have the following representation

42x + 12 = 2(21x + 6)

Factor out 3 from the expression

So, we have the following representation

42x + 12 = 2 * 3(7x + 2)

Evaluate the products

42x + 12 = 6(7x + 2)

The height of the cone is 580.36 cm.

The curved surface area of the cone is given by,

[tex]A = \pi \sqrt{h^{2} +r^{2} }[/tex]

Squaring both sides, we get :

[tex]A^{2} =\pi ^{2} (h^{2} +r^{2} )[/tex]

Now, it is given that the height of the cone is h,

The area of the cone = 550 [tex]cm^{2}[/tex]

And the radius of the cone = 7cm,

Putting these values in the given formula, we get,

[tex]A^{2} =\pi ^{2} (h^{2} +r^{2} )[/tex]

[tex]550^{2} = \pi ^{2} * ( h^{2} +7^{2} )\\[/tex]

Answer:

A) 0.5

B) 10

Step-by-step explanation:

A) First, you need to Combine Like Terms on the right side of the =

98-248 = -150

Now, you need to Isolate the variable by getting rid of the -178. What you do to one side, you must do the the other.

56a-178(+178) = -150(+178)

56a = 28

Finally, you must remove that 56 on the a. Since it stands for 56 x a, you must do the same you did with the -178 except with Division.

56a/56 = 28/56

a = 0.5

B) Combine Like terms

640+70 = 710

Isolate the variable

710(-20) = 69y+20(=20)

690 = 69y

Remove the 69 with division

690/69 = 69y/69

10 = y

The Amount of money that she received at the end of the read is $4024, the relationship between the number of years Ira has his money invested and the balance in any year differs by $24 which is the simple interest.

Amount invested by Ira = P = $4000

The rate of Interest (r) = 0.6 %

Time period (t) = 1 year.

The simple interest is given by,

[tex]S.I. = \frac{P*r*t}{100}[/tex]

Now, putting the values in the formula, we get:

[tex]S.I. = \frac{4000*0.6*1}{100} =24[/tex]

Hence, the simple interest will be $24

Now, the Amount/balance that she received in the year is A = P +S.I

A = P+S.I.

A = 4000 +24 = $4024

Step-b-1/5y-step explanation:

The rule for a perpendicular slope of a line is -1/s

In this case, we find the slope of the line first.

y = 5x + 7

The slope is 5, so -1/(5) is the slope of the perpendicular line.

The sales revenue necessary to generate net income of $100,000 is: $416,667.
