Answer:

[tex]-\frac{1}{2}[/tex]

Step-by-step explanation:

The slope of a line is the change in the line, it is also called; [tex]\frac{rise}{run}[/tex]. The equation to find the slope of a line is;

[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

Substitute in the given points;

( 2, 6 ) and ( 8, 3 )

[tex]\frac{3 - 6}{8 - 2}[/tex]

Simplify,

[tex]\frac{-3}{6}[/tex]

[tex]-\frac{1}{2}[/tex]

Answer:

[tex]x = 25[/tex]

Step-by-step explanation:

[tex](4x) + (5 + 3x) = 180[/tex]

[tex]4x + 5 + 3x = 180[/tex]

[tex]7x + 5 = 180[/tex]

[tex]7x = 180 - 5[/tex]

[tex]7x = 175[/tex]

[tex] \frac{7x}{7} = \frac{175}{7} [/tex]

[tex]x = \frac{175}{7} [/tex]

[tex]x = 25[/tex]

Answer:

k = 70

Step-by-step explanation:

k = 6x + 100

k = 6(-5) + 100

k = -30 + 100

k = 70

Answer:

m < 1200

Step-by-step explanation:

0.10m + 130 < 250

-130                -130

0.10m < 120

/0.10      /0.10

m < 1200

The question is incomplete as it is missing the length of the book spine and length of the staple.

Assume the question goes thus :

Elena is binding a small booklet with a spine that is 15 inches long. She uses staples that are 0.5 -inch long. If she puts the staples end-to-end through the booklet, without gaps or overlaps between them, how many staples would it take to bind the booklet?

Answer:

30 staples

Step-by-step explanation:

Given that:

Length of book spine = 15 inches

LENGTH of staple = 0.5 inch

Since it is assumed that staples are applied end-to-end on the book without gaps ; the number of staples which will be used is ;

Length of book spine / length of staple

= 15 inches / 0.5 inch

= 30 staples

Answer: -0.010039

Answer:

y>-2

Step-by-step explanation:

that is the answer

____________________________

 - We do this because when solving this they are in parenthesis, so you must get rid of the parenthesis by turning them negative.

Equation at the end of Step 1:

 - We do this since we can only have on variable at the end of the problem, so you just combine them if they have the same variable base.

Equation at the end of Step 2:

 - We do this because we need one number left over to get a simplified version of this equation.

Answer:

q=3s+4t

q-4t=3s

(q-4t)/3=s

Step-by-step explanation:

Given:

[tex]f(x)=4x-7[/tex]

[tex]g(x)=4x[/tex]

To find:

The expression for f(f(x)).

Solution:

We need to find f(f(x)).

[tex]f(f(x))=f(4x-7)[/tex]                             [tex][\because f(x)=4x-7][/tex]

[tex]f(f(x))=4(4x-7)-7[/tex]                             [tex][\because f(x)=4x-7][/tex]

Using distributive property, we get

[tex]f(f(x))=4(4x)+4(-7)-7[/tex]

[tex]f(f(x))=16x-28-7[/tex]

[tex]f(f(x))=16x-35[/tex]

Therefore, the expression for f(f(x)) is [tex]f(f(x))=16x-35[/tex].

Answer:

5

Step-by-step explanation:

58+78=131

180-131=49

10(5)-1

=5

Answer:

x=5

Step-by-step explanation:

A triangle= 180

53+78+10x-1=180

Combine like terms

130+10x=180

Subtract by 130 on both sides

10x=50

Divide by 10 on both sides

x=5

Answer:

250%

Step-by-step explanation:

Hi there!

In order to solve this problem, we have to divide 200 by 80.

When we do this, we get 2.5. The number in the ones spot, in this case 2, would be worth 200%.

Now we have the 0.5

A half is equivalent to 50%, so we add those two percentages together to get 250%.

I hope this helps!

Step-by-step explanation:

Answer:

It's A

Step-by-step explanation:

Because both triangles have the same side connected to, which means that that side is congruent to each other and because it tells us that JL and JK are congruent and KM and ML are congruent that means that its sss. Also, it is not giving us an angle to find the congruence so it has to be sss.

Answer: 3

Step-by-step explanation: Figure B has side measures 16, 20, and 9. Figure A has side measures 48, 27, and 60. The ratio of each of the corresponding sides is 1:3 (16:48, etc). Therefore, the scale factor of Figure B to Figure A is 3.

Answer:

2750 chocolates

Step-by-step explanation:

Find how much she has bought already:

1,125(2)

= 2,250

Then, subtract this from 5,000

5000 - 2250

= 2750

So, she still needs 2750

Answer:

2,750

Step-by-step explanation:

2 cases of 1,125 chocolates = 2,250 chocolates

5,000 - 2,250 = 2,750 more chocolates needed

(that's also 3 cases of chocolates needed :p)

Answer:

1.

Step-by-step explanation:

Lets make [tex]4\frac{1}{2}[/tex] into a improper fraction!

Whole number times denominator and add denominator 2 x 4+1= 9

Now we divide

[tex]\frac{9}{9} =1[/tex]

So each person gets 1 amount of food.
