Answer:

[tex]-\frac{3}{2} , 5[/tex]

Step-by-step explanation:

The zeroes of a function are the x values of the points at which the graph intersects the x-axis. All points on the x-axis have a y-value of 0, therefore, we need to find out which values of x can be plugged in to have the result be 0. This function is already factored out. So, for each expression, find which input of x makes the result equal 0.

1) So, start with 2x + 3. Set it equal to 0 and solve for x:

[tex]2x + 3 = 0\\2x = -3\\x = -\frac{3}{2} \\[/tex]

Therefore, [tex]-\frac{3}{2}[/tex] is one of the zeroes.

2) Next, set x-5 equal to 0 and solve, too:

[tex]x - 5 = 0 \\x = 5 \\[/tex]

Therefore, 5 is one of the zeroes.

3) Thus, the zeroes are [tex]-\frac{3}{2}[/tex] and 5.

Answer:

y=-1500x + 21000

Step-by-step explanation:

I =PRT

I = interest

P = principal

R = interest rate%

T = time

The straight-line depreciation equation would be; y=-1500x + 21000

An equation is an expression that shows the relationship between two or more numbers and variables.

Given that car that Sophia wants to buy costs $21,000. She does research that after 14 years the car depreciates to a value of zero.

The standard exponential equation is [tex]y = a(1-r)^t[/tex]

r is the rate

t is the time

a is the initial value

Given the following;

r = 12% = 0.12

t = 14 years

a = $21000

Substitute;

y = 21000(1 -0.12)^14

y = $1500

Therefore, the straight-line depreciation equation would be;

y=-1500x + 21000

Answer:

1.1 * 10 ^ -3

Step-by-step explanation:

Given the value of the thivkness of a dollar bill to be 0.0011metre

The standard scientific notation is expressed as A * 10^n

A is any value between 1 and 10 where n is any integer

0.0011 = 11/10000

0.0011 = 11 *1/1000

0.0011 = 11 * 0.0001

0.0011 = 1.1 * 0.001

0.011 = 1.1 * 10 ^ -3 (Note that the decimal point is shifted forward three times and the power is negative because the value is less than 1)

Answer:

Rise over Run

Step-by-step explanation:

The slope and y-intercept values indicate characteristics of the relationship between the two variables x and y. The slope indicates the rate of change in y per unit change in x. The y-intercept indicates the y-value when the x-value is 0.

Answer:

The slope of the line = m = 3

Step-by-step explanation:

Given the table

x           3          6            8           12

y           7          16          22          34

Taking any two points let say (3, 7) and (6, 16)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]  

                 =  [16 - 7] / [6 - 3]

                  = 9 / 3

                 = 3

Therefore, the slope of the line = m = 3

Step-by-step explanation:

3x° + 46° +14°

3*10° + 46 + 14° =90

therefore the value of x is 10

The value of x on the given figure is 10.

Option D is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

From the figure,

3x + 46 + 14 = 90

Now,

Simplifying.

3x + 60 = 90

Subtracting 60 on both sides.

3x = 90 - 60

3x = 30

Dividing 3 into both sides.

x = 10

Thus,

The value of x on the given figure is 10.

Answer:

B and C

Step-by-step explanation:

First you have to find a common denominator which would be 18. Then you need to multiply the denominators to get to 18. 6x3 and 9x2. Now whatever you do to the bottom you have to do to the top. So you would mutiply 5x3 and 7x2. The fractions you are left with are, 14/18 and 15/18.

To solve the problem we need to know about fractions.

A fraction is a way to describe a part of a whole. such as the fraction [tex]\frac{1}{4}[/tex]can be described as 0.25.

Given to us

To bring the denominator, we need to take the LCM of the denominator, therefore,

[tex]\dfrac{5}{6},\ \dfrac{7}{9}[/tex]

we know that the LCM of 6 and 9 is 18. therefore,

[tex]=\dfrac{(5\times 3)}{(6\times 3)},\ \dfrac{(7\times 2)}{(9\times 2)}\\\\=\dfrac{15}{18},\ \dfrac{14}{18}[/tex]

Answer:

[tex]x\le -80[/tex]

Step-by-step explanation:

The given statement is "18 less than the quotient of a number and -5 is at most -2",

Let the number be x.

At most means, a ≤ b

So,

[tex]\dfrac{x}{-5}-18\le-2[/tex]

Adding 18 to both sides.

[tex]\dfrac{x}{-5}-18+18\le-2+18\\\\\dfrac{x}{-5}\le16[/tex]

Multiply both sides by -5

[tex]\dfrac{x}{-5}\times -5\le 16\times -5\\\\x\le -80[/tex]

So, the solution of the given statement is x is less than equal to -80.
