Step-by-step explanation:

[tex]f(x)=mx+b[/tex]

[tex]f(-3)=-3[/tex] meaning that (-3,-3)

[tex]f(5)=4[/tex] meaning that (5,4)

(1 ) Find slope.

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{4+3}{5+3}\\m=\frac{7}{8}[/tex]

The slope is 7/8

(2) Substitute any ordered pairs in the equation.

I'll use (5,4)

[tex]f(x) = \frac{7}{8}x+b\\4=\frac{7}{8}(5)+b\\4=\frac{35}{8}+b\\32=35+8b\\32-35=8b\\-3=8b\\-\frac{3}{8}=b\\b=-\frac{3}{8}[/tex]

Therefore the equation for f(x) is [tex]f(x)=\frac{7}{8}x-\frac{3}{8}[/tex]

Step-by-step explanation:

I have high iq

-4(3/2x - 1/2) = -15

Distribute -4

-6x + 2 = -15

Subtract 2 from both sides

-6x = -17

Divide 6 from both sides

x = 2.83333333333333333

Inequalities Of The Form “x – a < b” or “x – a > b”

The solution of the inequality 1 1/8 + b ≥ 7/16 will be;

⇒ - 11/16 ≤ b

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

The inequality is,

⇒ 1 1/8 + b ≥ 7/16

Now,

Solve the inequality as;

The inequality is,

⇒ 1 1/8 + b ≥ 7/16

Solve for b as;

⇒ 9/8 + b ≥ 7/16

Subtract 9/8 as,

⇒ 9/8 + b - 9/8  ≥ 7/16 - 9/8

⇒ b ≥ (7 - 18) / 16

⇒ b ≥ - 11/16

⇒ - 11/16 ≤ b

Thus, The solution of the inequality 1 1/8 + b ≥ 7/16 will be;

⇒ - 11/16 ≤ b

Step-by-step explanation:

Answer:

x <(with a line underneath the carrot) -11

Step-by-step explanation:

Hope this helps! Could not find the symbol.

The inequality for x which is less than or equal to -11 is written as x ≤ -11 or  x + 11 ≤ 0.

Inequality shows relation between two expression which are not equal to each others.

Let the required number is x.

In the given question,

Number x is less than or equal to -11.

The inequality for x which is less than or equal to -11 can be written as,

x ≤ -11

The inequality can be further simplified as,

⇒x + 11 ≤ 0

The inequality for x is x + 11 ≤ 0.

Answer:

24 toys

Step-by-step explanation:

line up your numbers by the type of unit they have :

80 toys represent  100% of the toys

  ? toys represent  30% that are stuffed animals

Cross-multiply

?*100 = 30*80

divide both sides by 100

?= 30*80/100= 24

Answer:

Here we have four individual events.

First selection, second selection, third selection and fourth selection.

Where initially, the options are 16 Americans and 13 Canadians.

Now, to see if the events are dependent or independent.

Suppose that in the first selection, an American is selected.

Then the second selection has 15 Americans and 13 Canadians as options.

Now, if in the first selection, a Canadian is selected.

Then in the second selection, the options will be 16 Americans and 12 Canadians.

Then the events are not independent.

Now we want to find the probability of randomly selecting a four-person committee consisting entirely of Canadians from a pool of 16 Americans and 13 Canadians

The probability of randomly selecting a Canadian is equal to the quotient between the number of Canadians, and the total number of postulants.

For the first selection, we have 13 Canadians, and 29 people in total, then the probability is:

P1 = 13/29.

Suppose that a Canadian is selected, now there are 12 Canadians and 28 people in total, then the probability for the second selection is:

P2 = 12/28

with the same reasoning as above, the probabilities for the third and fourth selections will be:

P3 = 11/27

P4 = 10/26.

The joint probability will be equal to the product of the individual probabilities, this is:

P = P1*P2*P3*P4 = (13/29)*(12/28)*(11/27)*(10/26) = 0.03

Answer:

All of them are ø

Step-by-step explanation:

There are two answers to this problem:

(11 + 4) = 3 * 8

and

(11 + 4) = 3 * -8

Lets do (11 + 4) = 3 * 8 first: 15=24

So this first one is ø

Lets do (11 + 4) = 3 * -8: 15=-24

Which also ø

Answer:

TA of longer piece = 2(lw) + 2(hw) + 2(lh) 2*1*1 +2*6*1 + 2*1*6 = 2 + 12 + 12 = 26 TA of shorter piece = 2(lw) + 2(hw) + 2(lh) = 2*1*1 + 2*3*1 + 2*1*3 = 14 Add the two surface areas together. 26 + 14 = 40 Subtract the area where the two pieces of wood are attached. Because that section will not be painted on either piece of wood, two times that area must be subtracted. 40 - (2*1*1) = how many square inches of purple?

Step-by-step explanation:

The cups needed to feed 24 people is 13[tex]\frac{1}{2}[/tex] cups.

Ratio expresses the relationship between two values. It is used to express the number of times that one value is contained within other value(s).

The cups of flour needed to feed one person = [tex]4\frac{1}{2}[/tex] ÷ 8

= [tex]\frac{9}{2}[/tex] × [tex]\frac{1}{8}[/tex] = [tex]\frac{9}{16}[/tex]

Number of cups needed to feed 24 people = number of cups needed to feed 24 people x 24.

[tex]\frac{9}{16}[/tex] x 24 = [tex]\frac{27}{2}[/tex] = 13[tex]\frac{1}{2}[/tex] cups

Answer:

x=12

Step-by-step explanation:

[tex] - 2x - 12 = - 36[/tex]

[tex] - 2x = - 36 + 12[/tex]

[tex] - 2x = - 24[/tex]

[tex]x = - 24 \div - 2[/tex]

[tex]x = 12[/tex]

Answer:

The answer is x=12

Step-by-step explanation:

-2(x+6)= -36

-2x+-12=-36

-2x+-12+12=-36+12

-2x=-24

Divide both sides by -2

-2x/2=-24/-2
