Step-by-step explanation:

Step 1: Define

-3x + 40 = -23

Step 2: Solve for x

Isolate x term:                    -3x = -63Isolate x:                             x = 21

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x:                    -3(21) + 40 = -23Multiply:                               -63 + 40 = -23Add:                                     -23 = -23

Here we see that -23 does indeed equal -23.

∴ x = 21 is the solution to the equation.

A medium artichoke contains about 14​% of the recommended amount of a certain mineral an average adult should have each day. About how many grams of the mineral should the average adult have each​ day?

Answers

Answer:

0.0238  g

Step-by-step explanation:

Given that:

the certain mineral = potassium and a medium artichoke contain about 0.17 g of it.

Suppose a medium artichoke contains about 14% of the recommended amount of a certain mineral.

On Average, the amount an adult should have each day = 0.17 g × (14/100)

-3(10+4v)=-6(5-9v)

step-by-step pls

Answers

Answer:

0

Step-by-step explanation:

Let's solve your equation step-by-step.

−3(10+4v)=−6(5−9v)

Step 1: Simplify both sides of the equation.

−3(10+4v)=−6(5−9v)

(−3)(10)+(−3)(4v)=(−6)(5)+(−6)(−9v)(Distribute)

−30+−12v=−30+54v

−12v−30=54v−30

Step 2: Subtract 54v from both sides.

−12v−30−54v=54v−30−54v

−66v−30=−30

Step 3: Add 30 to both sides.

−66v−30+30=−30+30

−66v=0

Step 4: Divide both sides by -66.

−66v

−66

Find the largest degree of x that can be factored out of all terms
9x and 45​

What are some basic properties of exponentiation?

If we have [tex]a^b[/tex] then 'a' is called base and 'b' is called power or exponent and we call it "a is raised to the power b" (this statement might change from text to text slightly).

Exponentiation(the process of raising some number to some power) have some basic rules as:

[tex]a^{-b} = \dfrac{1}{a^b}\\\\a^0 = 1 (a \neq 0)\\\\a^1 = a\\\\(a^b)^c = a^{b \times c}\\\\ a^b \times a^c = a^{b+c} \\\\^n\sqrt{a} = a^{1/n} \\\\(ab)^c = a^c \times b^c\\\\a^b = a^b \implies b= c \: \text{ (if a, b and c are real numbers and } a \neq 1 \: and \: a \neq -1 )[/tex]

How can we rewrite a constant as a coefficient?

Suppose there is a constant 'c'.

We can write it as:

[tex]c = c \times 1 = c \times x^0[/tex]

where 'x' is the variable in consideration. Here even when x = 0, we would assume that for all real numbers 'x', its power raised to 0 makes it evaluate to 1.

For this case, we can rewrite both the terms as:

[tex]9x = 9x\times 1 = 9x \times x^0[/tex][tex]45 = 45 \times 1 = 45 \times x^0[/tex]

Thus, the maximum of x that can come out common out of these two terms is [tex]x^0[/tex] (its degree, or power, or exponent is 0)

Thus, the largest degree of x that can be factored out of all terms 9x and 45​ is 0

What is Polynomial?

A polynomial is a mathematical equation that solely uses the operations addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are sometimes known as indeterminate in mathematics. Majorly used polynomials are binomial and trinomial.

Given a trinomial equation:

f(x)=x^3+kx-4

And also given it has a factor (x - 1)

Thus, at x = 1 the value of the f(x) will be 0

So,

f(x) = x^3 + kx - 4

f(1) = 1^3 + k*1 - 4

0 = 1 + k -4

k = 3

therefore, The value of k = 1 for the given Trinomial that has  the factor (x -1)

Find the slope (3,6)
(3,-3) need in 5 minutes

Answers

Answer: The slope is undefined.

Step-by-step explanation:

Using the formula given, find the difference in the y coordinates of the points and divide it by the x coordinates.

(3,6)

(3,-3)  

y coordinates:  6 - (-3) =  9

x coordinates:   3- 3 = 0  

9/0 =  undefined.

Any number being divided by 0  is undefined because you can't divide something by anything.  

Also remember that if a line is vertical through any of the x coordinate, the slope will always be undefined and the equation of line is x = 3

The function f(x) = –2x2 + 32 represents the height of an object, f(x), after x seconds. How many seconds does it take for the object to hit the ground?

Answers

Given:

The height of an object, f(x), after x seconds is

[tex]f(x)=-2x^2+32[/tex]

To find:

The time taken be object to hit the ground.

Solution:

We have,

[tex]f(x)=-2x^2+32[/tex]

The object will hit the ground if the height is 0, i.e., f(x)=0.

[tex]0=-2x^2+32[/tex]

[tex]2x^2=32[/tex]

Divide both sides by 2.

[tex]x^2=\dfrac{32}{2}[/tex]

[tex]x^2=16[/tex]

Taking square root on both sides.

[tex]x=\pm 4[/tex]

Time cannot be negative. So, x=4.

Therefore, the object will hit the ground after 4 seconds.
