A rectangle with sides measuring x in. and 4x-1 in. has an area of 663in.^2. What are the dimensions of the rectangle?

Answers

9514 1404 393

Answer:

  13 in by 51 in

Step-by-step explanation:

The area is the product of the dimensions, so is ...

  663 = x(4x -1)

  4x^2 -x -663 = 0 . . . . . . subtract 663 to put in standard form

Using the quadratic formula, we can find the solutions.

  x = (-(-1) ±√((-1)^2 -4(4)(-663)))/(2(4))

  x = (1 ± √10609)/8 = (1 ±103)/8

Only the positive solution is of any use in this problem, so ...

  x = 104/8 = 13

  4x-1 = 4(13)-1 = 51

The dimensions of the rectangle are 13 inches by 51 inches.

The velocity of a car increases from 4 m/s at 2 sec. To 32 m/s at 9 sec. What is the car's average acceleration?

Answers

Answer:

Acceleration, [tex]a=4\ m/s^2[/tex]

Step-by-step explanation:

Given that,

Initial speed = 4 m/s at 2 seconds

Final speed = 32 m/s at 9 seconds

We need to find car's average acceleration. We know that average acceleration is equal to the change in speed divided by the change in time. So,

[tex]a=\dfrac{v_2-v_1}{t_2-t_1}\\\\=\dfrac{32-4}{9-2}\\\\=\dfrac{28}{7}\\\\=4\ m/s^2[/tex]

So, the car's average acceleration is equal to [tex]4\ m/s^2[/tex].

Answers

Answer:

The range of values of [tex](f + g)(x) \ge 3[/tex] is for all values of x [tex]-\infty[/tex] to [tex]+\infty[/tex]

Step-by-step explanation:

Given

[tex]f(x) = |x| + 9[/tex]

[tex]g(x) = -6[/tex]

Required

Describe the range of [tex](f+g)(x)[/tex]

First, calculate [tex](f+g)(x)[/tex]

[tex](f+g)(x) = f(x) + g(x)[/tex]

Substitute values for f(x) and g(x)

[tex](f+g)(x) = |x| + 9 -6[/tex]

Evaluate Like Terms

[tex](f+g)(x) = |x| + 3[/tex]

The above expression shows that [tex](f + g)(x) \ge 3[/tex]

Because [tex]|x| \ge 0[/tex]

Hence, the range of values of [tex](f + g)(x) \ge 3[/tex] is for all values of x [tex]-\infty[/tex] to [tex]+\infty[/tex]

What is the equation of the line that passes through the point (5, – 7) and
has a slope of o?

Answers

Answer:

The answer is

[tex]y = - 7[/tex]

Answer:

y = -7

Step-by-step explanation:

Hey :)

y = mx + b

*m is equal to the slope...

y = (0)x + b

Plug in the point you have...

-7 = (0) (5) + b

-7 = 0 + b

-7 = b

y = (0)x - 7

y = -7

Ignore the (0)x because anything multiplied by 0 is 0 so there's no point in having 0x in your equation.

Answer: y = -7

Solve for j.

j
-2
+ 7 = -12
=

Answers

Answer: j= −17 /3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3j−2+7=−12

3j+−2+7=−12

(3j)+(−2+7)=−12(Combine Like Terms)

3j+5=−12

3j+5=−12

Step 2: Subtract 5 from both sides.

3j+5−5=−12−5

3j=−17

Step 3: Divide both sides by 3.

3j /3 = −17 /3

j= −17 /3

Mason pulled his hamstring while at track practice and received an MRI. His medical bills totaled

$1,200. How much would he have to make in order to pay his bills if he did not use an FSA or HSA?

Answers

Answer:

a minimum of $1,200

Step-by-step explanation:

The flexible spending accounts (FSA) and health savings accounts (HSA) are basically accounts that help pay for your medical bills and therefore, drastically reduce the total amounts that you would have to pay out-of-pocket. Therefore, in this scenario, if Mason does not use an FSA or HSA then he would have to make a minimum of $1,200 to completely pay off his medical bill in full. Otherwise, he would still owe money.

which figure is a translation of Figure A? explain. A translation, or slide, is a transformation that moves every point of a figure the same distance & the same direction. ​

Answers

Answer:

Figure B

Step-by-step explanation:

A translation does not "flip" the position of the pre-image. Figure C is a reflection of figure A.

A translation would "slide" the figure into a new position without mirroring nor rotating it.        

Figure B should be the translation of Figure A.

Hope this helps.

Figure B is the translation of figure A by 2 units up.

What is the transformation of the graph?

If a graph is translated and rotates by any amount either in x and y direction then it will be transfomation of the graph.

For example transformation of graph f(x) by 2 units down.

The new resultant graph could be only translated or rotated or both.

Given figure A

If we look at C then the face of this is towards the right but in figure A the face is towards the left.

So it means C will translate + rotation of graph A it will not be pure translation.

In figure B it is clear that it is a translation of figure A by 2 units upward.

Hence "Figure B is the translation of figure A by 2 units up".

Solve d=rt for r thanks!!!!

Answers

r = d/t :) Any questions? I got you.

Answer:

Step-by-step explanation:

So you know that distance = rate x time.

9 miles in 1.5 hours

In this case, you know the time (1.5 hours) and the distance (9 miles)

(You can ignore the rest of the chart since the question is just about running.)

What's missing is the rate (r) at which you ran. (Think of it as speed...)

If r x t = d, that means that d ÷ t = r

So plug in what you have: 9 ÷ 1.5 = your rate. And 9 ÷ 1.5 is...

6

So you ran 6 miles per hour. And you can check it: if you went 6 miles in one hour, you could go another 3 miles in another half an hour. That would be 9 miles in 1.5 hours. Check!
