Answer:

Part A: You are buying candy bars online. They cost $6 each and there is an $18 shipping fee. You have $72 to spend. How many candy bars can you get?

Part B: x=9

Step-by-step explanation:

6x + 18= 72

You want to get x alone:

Subtract 18 from both sides

Rewrite:

6x= 72-18

Now, subtract 72-18

Rewrite:

6x= 54

Divide 6 from both sides

So, that would be 54/6

Answer:

Step-by-step explanation:

The discriminant of this equation, i.e, D=\(b^{2}-4ac\) is less than 0:

D= 0-(4*2*18)   --> which is clearly negative

When D is less than 0, the equation has no real number solutions.

Therefore, \(2x^{2}+18=0\) has no real roots

Answer:

Step-by-step explanation:

0 has no roots so thats one, and im just trying to complete a challenge so sorry if im wrong :( but make other person brainliest they did good job :)

Volume is calculated using the formula volumes = 0.5 * b * h * length, where b is the triangle's base length, h is its height, and length is the prism length.

Answer:

There is only one x intercept: x = -0.5 or -1/2

Step-by-step explanation:

To find the x-intercepts of the graph of the function, we need to find the values of x where y = 0. In other words, we need to solve the equation 4x^2 + 4x + 1 = 0 for x.

4x^2 + 4x + 1 = 0

(2x+1)^2 = 0

2x + 1 = 0

2x = 0 -1

x = -1/2

Answer:

\(f^{-1}\left(f(576)\right)=\boxed{576}\)

\(f^{-1}(-7)+f(-7)=\boxed{13}\)

Step-by-step explanation:

The inverse of an invertible function with the domain of all real numbers is obtained by reflecting the original function across the line y = x, which swaps the input and output values of the function. Therefore, (x, y) → (y, x).

Given table:

\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&-7&11&-13&6&5&-9\\\cline{1-7}\vphantom{\dfrac12}f(x)&7&12&8&-7&13&5\end{array}\)

Inverse function:

\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&7&12&8&-7&13&5\\\cline{1-7}\vphantom{\dfrac12}f^{-1}(x)&-7&11&-13&6&5&-9\end{array}\)

If we have a function f(x), the inverse function is denoted as f⁻¹(x), and it has the property that f⁻¹(f(x)) = x for all valid inputs x in the domain of f(x).

Therefore:

\(\large\boxed{f^{-1}\left(f(576)\right)=576}\)

The value of f(-7) is the value of f(x) when x = -7. Therefore, reading from the original table, f(-7) = 7.

The value of f⁻¹(-7) is the value of f⁻¹(x) when x = -7. Therefore, reading from the inverse function table, f⁻¹(-7) = 6.

Therefore:

\(\large\boxed{\begin{aligned}f^{-1}(-7)+f(-7)&=6+7\\&=13\end{aligned}}\)

Answer:

Step-by-step explanation:

The question says find the number eight times of a certain two digit number exceeding the number 19.The tens digit than the units digit . So,you have to multiply eight to a two digit number exceeding 19 so you find a number exceeding 19 which would have to be able to to multiply by eight to exceed the number 19

find the number eight times of a two digit number higher than the number nineteen. The tens digit than the units digit .you have to multiply 8 to a 2 digit number exceeding nineteen so you find a number exceeding ninteen which would have to be able to to times by 8 to go higher than the number nineteen

Step-by-step explanation:

Step-by-step explanation:

the first persons mistake:

-6/-3 isn't -2 it's 2 so they divided wrong

the second persons mistake:

they added 7 instead of taking it away which is why they got 8 instead of -6

how to work it out:

-3w+7=1

first take away 7 from both sides

-3w=-6

then divide each side by -3 to get w by itself

w=2

Answer:

w=2

Step-by-step explanation:

The mistake on the first problem is that -6 / -3 does not equal negative 2, it equals positive 2.

The mistake on the second problem is that 1 - 7 does not equal 8, it equals -6

Answer: If you mean LCM, the LCM of 10 and 15 would be 30.

Step-by-step explanation:

The LCM of two non-zero integers, x(10) and y(15), is the smallest positive integer m(30) that is divisible by both x(10) and y(15) without any remainder.

The system of inequalities associated with the following graph are,

x + y ≥ 2.

4x + y ≥ - 1.

Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.

The symbol a < b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

a is less than or equal to b when a notation like a ≤ b.

a is bigger or equal value of an is indicated by the notation a ≥ b.

The coordinates of the first equation is, (0, 2), (2, 0).

Slope(m) = (0 - 2)/(2 - 0).

Slope(m) = - 2/2.

Slope(m) = - 1.

2 = - 1(0) + b.

b = 2.

y₁ = - x + 2.

The coordinates of the second equation is, (- 1, 3), (0, - 1).

Slope(m) = (- 1 - 3)/(0 + 1).

Slope(m) = - 4.

3 = 4 + b.

b = - 1.

y₂ = - 4x - 1.

So, The system of inequalities associated with the graph are,

x + y ≥ 2.

4x + y ≥ - 1.

Answer:

p=1                                  p = -5/3

Step-by-step explanation:

1-|3p+1|=-3

Subtract 1 from each side

1-|3p+1| -1=-3-1

-|3p+1|=-4

Divide by -1

|3p+1|=4

The absolute value has two solutions one positive and one negative

3p+1 = 4            3p+1 = -4

Subtract 1 from each side

3p+1-1 = 4-1            3p+1-1 = -4-1

3p = 3                         3p = -5

Divide by 3

3p/3 = 3/3                    3p/3 = -5/3

p=1                                  p = -5/3

Answer:

p=-5/3,1

Step-by-step explanation:

Subtract 11 from both sides.

-|3p+1|=-3-1

−∣3p+1∣=−3−1

2 Simplify  -3-1−3−1  to  -4−4.

-|3p+1|=-4

−∣3p+1∣=−4

3 Multiply both sides by -1−1.

|3p+1|=4

∣3p+1∣=4

4 Break down the problem into these 2 equations.

3p+1=4

-(3p+1)=4

Answer:

10.57 m

Step-by-step explanation:

Let the height of the parallelogram be x m

Area of the parallelogram = base*height

                                645    = (61 * x ) m

                                 x = 645/61

                                    = 10.57 m

Hope this helps

Height of parallelogram = 10.57m

Given,

Base of parallelogram = 61 m

Area of parallelogram = 645 m²

Now, according to formula

Area of parallelogram = Base × Height

Substitute the given values in the formula,

645 = 61 × height

Height = 10.57 m

Hence, the height of the parallelogram with area 645m² and base 61 m is 10.57 m  .
