Evaluate the expression. [(3–5)(34)]3

Answer:

yes they are equivalent

Answer:

X=-4

Step-by-step explanation:

the first thing you do is add 1 to both sides to make the variable be alone

-6x=24

now divide 6 on both sides the variable cancels out and your left with 24/-6

so your answer is -4

Answer:

Answer: -2x+12

Step-by-step explanation:

So, it says the expression equals 2A + B. That means you need to multiply the equation for A by 2 and then add the equation of B to it. The question is asking you to write it in standard form. It would look like this:

2(-2x+8) + 2x-4

-4x+16+2x-4

-2x+12

Answer:

square root of 16

Step-by-step explanation:

the square root of 16 is 4 and 4 times .5 equals 2

Answer:

x=3

Step-by-step explanation:

If y is 15 when x is 5, and y =f(x), then the equation is y=3x. Substitute in 9 for y, and do the algebra, and you will get 3. Hope this helped :D

The value of x is 3 when y = 9.

When two quantities are proportional, it means that they can be expressed as a ratio or a fraction, and this ratio remains constant as the values of the quantities change.

If y varies directly as x, it means that the ratio of y to x remains constant.

We can express this relationship as y = kx, where k is the constant of variation.

To find the value of k, we can use the given information that y = 15 when x = 5:

15 = k . 5

Dividing both sides of the equation by 5, we get:

k = 15/5

k = 3

Now that we have the value of k, we can substitute it into the equation

y = kx to find x when y = 9:

9 = 3x

Dividing both sides of the equation by 3, we get:

x = 9/3

x = 3

Therefore, when y = 9, x = 3.

Answer:

C/8    -k= y

Step-by-step explanation:

C=8(y + k)

Divide each side by 8

C/8 = y+k

Subtract k from each side

C/8  -k = y+k-k

C/8    -k= y

Answer: y  =  C /8 −  k

Step-by-step explanation: A=6

Answer:

Step-by-step explanation:

Refer the attached picture for complete question

a) V(x)=x(11-2x)(17-2x)

B(x)=140

Side and volume cannot be negative

So, x> 0

11-2x>0   and 17-2x>0

[tex]x<\frac{11}{2}[/tex] and [tex]x< \frac{17}{2}[/tex]

Domain for V(x) :[tex]0<x<\frac{11}{2}[/tex]

b)For finding the greatest Volume

[tex]\frac{dV}{dx}=0[/tex]

[tex]V(x)=x(11-2x)(17-2x)=4x^3-56x^2+187x[/tex]

[tex]\frac{dV}{dx}=12x^2-112x+187=0\\x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\x=\frac{112\pm\sqrt{(112)^2-4(12)(187)}}{2(12)}[/tex]

x=7.155 , 2.177

Consider the graph

So, Volume at 7.155 is negative

Thus x≈2 gives the greatest volume

c)

Consider the graph .

It is increasing from [tex]-1 \leq x \leq 2[/tex] and [tex]x \geq 7[/tex]

So, Graph increasing interval is [-1,2] ∪[7,∞)

d)

At the point of intersection, both graph has the same value .

Answer:

1/6

Step-by-step explanation:

In order to add or subtract fractions you have to have the same denominator for both factions. you do this through finding the Lowest Common Denominator (LCD) In this case it's six because both 3 and 6 (the denominators) can go into 6. So turn 1/3 into a fraction with 6 as the denominator through multiplying both the top and bottom of the fraction by 2

1/3 * 2/2 = 1*2/3*2 = 2/6

Then you can straightforwardly subtract

2/6 - 1/6 = 1/6

Answer:

V=72x³y³

Step-by-step explanation:

The formula to apply is;

V= l * w * h where

V= volume in units cubed.

l= length = 3xy

w=width = 4xy

h= height = 6xy

Substitute values in the formula as;

V= l*w*h

V=3xy * 4xy * 6xy ----find product for the numbers {3*4*6=72} then multiply by the product for x's {x*x*x =x³} that of y's {y*y*y=y³}

V= 72*x³*y³

V= 72x³y³  --------where xy are the units used.

Matthew will spend $26 to get to the hospital

Answer:

B

Step-by-step explanation:

We know that it costs 37 cents to mail a letter that weighs 1 oz or less. This would mean that for x ≤ 1, P(x) should equal 37. Already, we can eliminate A and D.

We also know that it costs an additional 26 cents for at most another ounce added to the original 1 ounce. This means that for 1 < x ≤ 2, P(x) = 26 + 37 = 63. This is shown by B.

Thus, the answer is B.

Answer:

Step-by-step explanation:

Let Lucas final grade be x

All Lucas grade will be 75, 78, 82, and 84 and x.

Average score = 95

Since we are not told what to look for, we can find the Lucas final grade.

Using the formula for calculating mean (average)

Mean = Sum of the score/total test taken

95 = 75+78+82+84+x/5

95 = 319+x/5

Cross multiply

95×5 = 319+x

475 = 319+x

x = 475-319

x = 156

Lucas final grade is 156

One sixth of Lucas final grade = 1/6 × 156 = 26
