Answer 1

Answer:

f(5) = 3

Step-by-step explanation:

f(x) is the y coordinate at x.

At x = 5, y = 3, so f(5) = 3.

If f(x)=2(x-3)x4, what is f(-2)? PLEASE HELP ILL GIVE BRAINLIEST

Answers

Answer:

f(-2) = -40

Step-by-step explanation:

f(x) = 2(x - 3) • 4

Plug in -2 for x.

f(-2) = 2(-2 - 3) • 4

Follow PEMDAS

f(-2) = 2(-5) • 4

f(-2) = -10 • 4

f(-2) = -40

Answer:

[tex]f(x) = 2(x - 3) \times 4 \\ f(x) = 8(x - 3) \\ f( - 2) = 8( - 2 - 3) \\ f( - 2) = 8 \times ( - 5) \\ \boxed{f( - 2) = - 40}[/tex]

- 40 is the right answer.

My remainder is 8. My dividend is 80. I am a 1- digit number. What divisor am I?

Answers

Answer:

9 is the answer..

Step-by-step explanation:

pls mark me the brainliest

Answer:

The divisor is 9.

Step-by-step explanation:

a) Data and Calculations:

Remainder = 8

Dividend = 80

Number divided evenly without remainder 8 = 80 - 8 = 72

72/9 = 8

b)There are four main numbers under the divisional mathematical rule. The first number is the dividend which is the number 80 that is being divided by the divisor. The divisor (9) is the number that divides 80. The quotient (8) is the result obtained by the division, while the remainder 8 is the number left over after the division.

Answers

Answer:

Step-by-step explanation:

The input is the value of x. Substitute x = 4 into y for output

y = 3(4)² - 2(4) + 5 = 3(16) - 8 + 5 = 48 - 8 + 5 = 45

Moises ate 10% of the candies in the bag. If Moises ate 16 candies, how many candies were there total in the bag?

Answers

Answer:

160

Step-by-step explanation:

10% of the candies is 16, and to get 100% from 10% is to multiply by 10.

So 10% *10 = 100%, then by association if 16 = 10%, then 16*10 will be the total 100%.

ABCD is a rhombus.
Find each angle.
Reason:

Plz answer ASAP, thank you

Answers

Answer:

Step-by-step explanation:

I sympathize. The question is not very clear: you don't know what A and B really are (I mean which vertex).

However it is a rhombus, and you are to assume that B follows A. So put A anywhere and make B follow it. They are supplementary which means they add to 180 degrees. All rhombi have that property.

A + B = 180

A/B = 2/1

Cross Multiply the second equation

A = 2*B

Put 2B into the first equation.

2B + B = 180 Combine the left terms

3B = 180 Divide both sides of the equation by 3

B = 180 / 3

B = 60

A = 180 - 60 = 120

Label the two acute angles as 60 and the two obtuse angles as 120.

Acute: means less than 90

Obtuse: means more than 90

How many solutions does 46x– 23 = 46x + 23 have

Answers

Answer:

no solution

Step-by-step explanation:

Let's first try to solve this.

Notice that there is a 46x term on both sides, so we can subtract both sides by 46x, leaving us with:

-23 = 23

Well... this is a false statement: -23 does not equal 23.

Thus, this as no solution.

Answer:

No solutions found

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

46*x - 23 - (46*x + 23) = 0

Equations that are never true

Solve : -46 = 0

This equation has no solution.

A non-zero constant never equals zero.

In a 45,45,90 triangle the hypotenuse is (x)sqrt2 while the side lengths are equivalent being a single value x. Therefore, when given the hypotenuse and solving for the leg, divide 4 by sqrt2 to get 4sqrt2/2 which simplifies to 2sqrt2 when the denominator and numerator cancel.

In a 30,60,90 triangle the short leg x is across from the 30 degree angle meaning the angle across from the 60 degree angle is x times the sqrt of 3. Therefore the long leg is 6sqrt3

1. m<1 = 139°

2. m<2 = 41°

3. x = 29

Step-by-step explanation:

1. m<1 = 86° + 53° (exterior angle theorem of a triangle)

m<1 = 139°

2. 133° = m<2 + 92° (exterior angle theorem of a triangle)

133° - 92° = m<2 (Subtraction property of equality)

41° = m<2

m<2 = 41°

3. 4x + 15 = 93° + (x + 9)° (exterior angle theorem of a triangle)

Add like terms

4x + 15 = 102 + x

4x - x + 15 = 102 (substraction property of equality)

3x + 15 = 102

3x = 102 - 15

3x = 87

x = 87/3 (division property of equality)

x = 29

the order of the surd 6 √2187 after simplification is

Answers

Answer:

[tex]n = 162[/tex]

Step-by-step explanation:

Given

[tex]6\sqrt{2187[/tex]

Required

Determine the order of the surd

If a surd is represented as [tex]n\sqrt{r[/tex], then the order of the surd is [tex]n[/tex]

[tex]6\sqrt{2187[/tex]

Express 2187 as [tex]3^6 * 3[/tex]

[tex]6\sqrt{2187} = 6\sqrt{3^6 * 3}[/tex]

Split the surd

[tex]6\sqrt{2187} = 6\sqrt{3^6} * \sqrt{3}[/tex]

Apply the following law of indices:

[tex]\sqrt{a} = a^{\frac{1}{2}}[/tex]

The expression becomes:

[tex]6\sqrt{2187} = 6 * 3^{\frac{6}{2}} * \sqrt{3}[/tex]

[tex]6\sqrt{2187} = 6 * 3^{3} * \sqrt{3}[/tex]

[tex]6\sqrt{2187} = 6 * 27 * \sqrt{3}[/tex]

[tex]6\sqrt{2187} = 162 * \sqrt{3}[/tex]

[tex]6\sqrt{2187} = 162 \sqrt{3}[/tex]

By comparing [tex]162 \sqrt{3}[/tex] to [tex]n\sqrt{r[/tex], we can say that:

[tex]n = 162[/tex]

[tex]r = 3[/tex]

Conclusively, the order of the surd is 162

Olivia is making model cars to go on shelves in her room. The number of wheels she uses is a function of how many cars she makes: if she makes 1 car, she uses 4 wheels; if she makes 2 cars, she uses 8 wheels; if she makes 3 cars, she uses 12 wheels; and so on. She has exactly 28 wheels she can use to make cars. What is the domain and range for the function?

Answers

Answer:

Domain = 1 to 7

Range = 4 to 28

Step-by-step explanation:

Given that:

Number of wheels used is a function of number of cars manufactured.

Number of wheels present = 28

1 car uses 4 wheels

2 cars use 8 wheels.

3 car uses 12 wheels

and so on.

Let the function be of the form:

[tex]y =f(x)[/tex]

Domain of the function is the value of [tex]x[/tex] that can be given as valid input to the function.

Range of the function is the value of [tex]y[/tex] that can be output of the function.

Let [tex]x[/tex] be the number of cars manufactured.

Then value of [tex]y[/tex] is nothing but [tex]x[/tex] times 4.

[tex]y=4x[/tex]

We are given that maximum value of [tex]y[/tex] can be 28.

[tex]28 = 4x\\\Rightarrow x =7[/tex]

Therefore, maximum value of input can be 7.

Minimum number of wheels can be 4 to make a minimum of 1 car.

Therefore domain is 4 to 28 and range is 1 to 7.

The midpoint of EF is M(1. – 1). One endpoint is E (– 3,2). Find the coordinates of endpoint F

The coordinates of F(x,y) is (5,-4) with midpoint of EF is M(1,-1)

What is midpoint of line segment?

The midpoint divides the line segment into two equal parts. As the number line progresses, the leftmost numbers become smaller, and the rightmost numbers become larger. Adding, subtracting, and multiplying can also be done using a number line like for addition move towards right and for subtraction move towards left.

Here, the mid point of line EF is M with coordinates (1,-1) with coordinates of E(-3,2) therefore, using mid point formula to find coordinates of F(x,y)

[tex]\begin{aligned}\frac{-3+x}{2}&=1\\x&=2+3\\&=5\end{aligned}[/tex]

and for y coordinates of F :

[tex]\begin{aligned}\frac{2+y}{2}&=-1\\y&=-2-2\\&=-4\end{aligned}[/tex]

Therefore, the coordinates of F(x,y) is (5,-4) with midpoint of EF is M(1,-1)
