Answer:

Four less than a unknown variable- C) y-4

Quotient of a variable and four- E) z÷4

some number to the power of four- B) a^4

Four times an unknown value- D) 4x

Four more than some number- A) B+4

Step-by-step explanation:

The final answers are:

Four less than an unknown value            C) y-4

Quotient of a variable and four                E) Z/4

Some number to the power of four         B) a⁴

Four times an unknown value                  D) 4x

Four more than some number                 C) b+4

An algebraic expression (or) a variable expression is a combination of terms by the operations such as addition, subtraction, multiplication, division, etc.

Let's analyze each statement separately:

- Four less than an unknown value --> this means that we have to subtract 4 to an unknown value. Calling  the unknown value, it means we have to write y-4

- Quotient of a variable and four --> this means we have to divide a variable by 4. Calling  the unknown variable, it means we have to write

z/4

- Some number to the power of four --> this means that we have to write the power of a number, in the form , where m in this case is equal to 4. Calling  the unknown number, it means we have to write a⁴

- Four times an unknown value --> this means that we have to multiply an unknown value by 4. Calling  our unknown values, we have to write 4x

- Four more than some number --> this means we have to add 4 to an unknown number. Calling  the unknown number, it means we have to write b + 4

Answer:

396 [tex]ft^{3}[/tex]

Step-by-step explanation:

Okay, so first we will find the triangle area.

9 * 8 = 72/2 = 36.

Now multiply this by 11 (the width of the prism)

36 * 11 = 396 [tex]ft^{3}[/tex]

Answer:

(+ 50,+ 11) are the points of the equilibrium point.

Step-by-step explanation:

demand is a negative line.

supply is a positive line.

Given b equals -3, determine if it is a solution to 4b - 6 = - 18.

So, we have our given which is b = -3, and we are asked to determine if it a solution to the above equation.

To do this, we can plug -3 in for b and see if it works out.

Work:

Plug in -3 for b.

4(-3) - 6 = - 18

-12 - 6 = -18

-12 - 6 = - 18

Thus, b = -3 is a viable solution for the equation of 4b - 6 = -18.

Answer:

biobooks = 204

mathbooks = 68

Step-by-step explanation:

the bio textbooks make up 3 parts

the math textbooks make up 1 part

the denominator therefore is 4

so biobooks = 272 * 3/4

and mathbooks = 272 * 1/4 (272 : 2 : 2)

note that calculating the mathbooks 1st is easier, bc you can then multiply by 3 to get the biobooks.

add both numbers up to proof that the sum is 272

Answer:

y= 5x +9

Step-by-step explanation:

Slope- intercept form:

y= mx+c, where m is the gradient and c is the y-intercept.

Parallel lines have the same gradient. Since the gradient of the given line is 5, the gradient of the unknown line is also 5. Hence, m=5.

y= 5x+c

To find the value of c, substitute a coordinate.

When y= -6, x= -3,

-6= 5(-3) +c

-6= -15 +c

c= 15 -6 (+15 on both sides)

c= 9 (simplify)

Thus, the equation of the line is y=5x+9.

Answer:

As it says in the graph, the situation we're dealing with are hours to meters. So, A would not be the correct answer. B shows proper use of both hours and meters with the right values. C is incorrect because the answer is B.

First we, Subtract the 16 from 2x ( which we can't do) so we change the equation to 16 - 2x = 4y

Second we, solve for x.  x = −2y + 8, We divide both sides by 2,

-2y/-2= y ( The two -2s cancle each other ) 8/2= 4

x = 4

Next we, solve for y. y = 4 −x/2y, we multiply both sides by 2y,

4 * 2y = 8y ( LOL ) -x/2y * 2y = -x

NOW WE have 8y - x

IDK anything beyond this I'm SORRY T.T

But for the coordinates x is 4

Answer:

x=6√3

y=12√3

Step-by-step explanation:

This is a 30 60 90 triangle.

The side opposite from the angle 60 is x√3, which makes 18=x√3, which eventually solves to x=6√3

The side opposite from the 90 degree angle is 2x, so multiply 6√3 by 2, which is 12√3, making y equal 12√3

I hope this helps :)
