Answer:

The solution is:

a. -18

b. -18

c. 24

d. 0

e. -4

4. 4

Step-by-step explanation:

Before we get into the solution, we remember the formula first, namely:

Addition

• (-) + (-) = (-)

• (+) + (+) = (+)

Subtraction

• (+) - (+) = can (-) and (+)

• (+) - (-) = (+)

Multiplication

• (-) x (-) = (+)

• (+) x (-) = (-)

Division

• (-) : (-) = (+)

• (+) : (-) = (-)

Solution:

a. 6(-3) = -18 ((+) × (-) = (-))

b. -6(3) = -18 ((-) × (+) = (-))

c. (-8)(-3) = 24 ((-) × (-) = (+))

d. -8(0) = 0 (whatever the number, if multiplied by 0 the result is still 0)

e. -20÷5 = -4 ((-) ÷ (+) = (-))

f. -36÷(-9) = 4 ((-) ÷ (-) = (+))

x = 135

Step-by-step explanation:

The two angles form a straight line so their sum is 180

x+2   + 43 = 180

Combine like terms

x+45 =180

Subtract 45 from each side

x+45-45 =180-45

x = 135

Answer:

A.

Step-by-step explanation:

The equation of the line is required.

The proportional relation of the graph is [tex]y=\dfrac{1}{7}x[/tex]

Two points of the line are

[tex](0,0)[/tex] and [tex](21,3)[/tex]

[tex]x_1=0[/tex]

[tex]y_1=0[/tex]

[tex]x_2=21[/tex]

[tex]y_2=3[/tex]

The equation of the line is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]\Rightarrow y-0=\dfrac{3-0}{21-0}(x-0)[/tex]

[tex]\Rightarrow y=\dfrac{1}{7}x[/tex]

Answer:

Her error in terms of inches was 2 inches while her percent error was 4.166%

Step-by-step explanation:

From the given data Claire estimated her brother to be shorter than he actually was. She estimated his height to be 4 feet while it was actually 4 feet 2 inches.

We convert the feet into inches because 12 inches are equal to a feet.

4 feet = 4 × 12 inches = 48 inches

4 feet 2 inches = (4 × 12 inches) + 2 inches = 48 + 2 = 50 inches

Error in terms of inches = 50 inches - 48 inches = 2 inches.

Step 2 ; Her percent error is given by dividing the difference in values by the actual value multiplied by 100.

% error = (difference in values / actual value) × 100

Claire's % error = (50 - 48)/ 48 × 100 = 2/48 × 100 = 0.04166 × 100 = 4.166%

Answer:

A 4% difference

Step-by-step explanation:

Convert 4 feet 2 into 4.16666666

4/4.16666666= 0.96 or 96%

4 feet was 96% of 4 feet 2 in

100 - 96= 4%

And this shows that there was a 4% error.

Answer:

8

Step-by-step explanation:

The questions is difficult to read but if it means "Jada has 12 library books checked out and Han has 1/3 less than that" Han would have 8 because 12/3 is 4. 12-4 is 8. This would only be correct if that is what the problem means. Sorry. I'm not sure what "LaTeX: \frac{1}{3}1 3" means.

The function f(x) = √x is not defined for the negative value of x. Then the correct option is C.

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

The function is given below.

[tex]f(x) = \sqrt{x}[/tex]

For x = -1, then the value of the function f(x) will be

[tex]f(-1) = \sqrt{-1}[/tex]

The function is not defined as a negative value.

For x = 0, then the value of the function f(x) will be

[tex]f(0) = \sqrt{0}=0[/tex]

For x = 1, then the value of the function f(x) will be

[tex]f(1) = \sqrt{1}=1[/tex]

For x = 4, then the value of the function f(x) will be

[tex]f(4) = \sqrt{4}=2[/tex]
