Choose the expression that represents a quadratic expression.
O 6x4 - 5x3 + 3x2 -7x - 8
) 5x3 + 3x2 -7x - 8
O 2x2 + 3x - 1
. 3x - 1

Answers

Answer 1

Answer:

3) 2[tex]x^{2}[/tex] + 3x - 1

Step-by-step explanation:

A quadratic expression is an expression involving a squared term

It can be written as y = a[tex]x^{2}[/tex] + bx + c, where a ≠ 0

// note that here b and c can be equal to 0

1) 6[tex]x^{4}[/tex] - 5[tex]x^{3}[/tex]  + 3[tex]x^{2}[/tex]  - 7x - 8 is simply incorrect because you can't write in the previously mentioned form. It is a quartic function, since the unknown variable x in forth degree. It can be written as y = a[tex]x^{4}[/tex] +b[tex]x^{3}[/tex] +c[tex]x^{2}[/tex] + dx + e, where a before [tex]x^{4}[/tex] ≠ 0

2) 5[tex]x^{3}[/tex]  + 3[tex]x^{2}[/tex]  - 7x - 8 is simply incorrect because you can't write in the previously mentioned form. It is a cubic function, since the unknown variable x in third degree.

3) 2[tex]x^{2}[/tex] + 3x - 1 is correct

4) 3x - 1 is incorrect because there is no squared term. You could also say that here a = 0 and write it as y = 0 * [tex]x^{2}[/tex]  + 3x - 1. It is also called a linear function because if you'd draw a graph, it would be a line

Answer:

No, A is

Step-by-step explanation:

You can tell by plugging in the numbers. 0 - 3(0) < 1 as 0 < 1.

Answer:  Choice A.  (0,0)

============================================================

Explanation:

Let's check if choice C is the answer or not

We will plug in x = -2 and y = 1 into the inequality to get

y - 3x < 1

1 - 3(-2) < 1

1 + 6 < 1

7 < 1

That's a false statement since 7 is not smaller than 1. This means the first inequality is false when (x,y) = (-2,1). So we can rule out choice C. Choices B and D are similar stories.

---------------

It turns out that choice A is the answer because

y - 3x < 1

0 - 3(0) < 1

0 - 0 < 1

0 < 1

Which is a true statement. So (x,y) = (0,0) is one solution to this inequality.

I'll let you check the other answer choices. You should find them to be false

The measure of angle Q is 70 degrees. Find the measure of angle P.

Answers

Answer:

∠ P = 40°

Step-by-step explanation:

Since PQ = PR then the triangle is isosceles and the base angles are congruent, then

∠ R = ∠ Q = 70° , so

∠ P = 180° - (70 + 70)° ← sum of angles in triangle is 180°

∠ P = 180° - 140° = 40°

The length, l , of a rectangle is 3 cm longer than twice the width, w. The perimeter of the rectangle is 66 cm.

Which system of linear equations could be used to find the length and width of the rectangle?
A. l = 3w + 2
2l + 2w = 66

B.l = 3w + 2
l + w = 66

C.I= 2w + 3
l + w = 66

D. l = 2w + 3
2l + 2w = 66

Answers

Answer:

The system of linear equations that could be used to find the length and width of the rectangle will be:

l = 2w + 3 cm  

2w + 2l = 66

Hence, option D is correct.

Step-by-step explanation:

Let the width of the rectangle be = w cm

Given that the length, l, of a rectangle is 3 cm longer than twice the width, w.

Thus, the length of the rectangle be:

l = 2w + 3 cm  

We know that the perimeter of the rectangle is:

P = 2w + 2l

Given that the perimeter of the rectangle = P = 66 cm

so substitute P = 66 in P = 2w + 2l

P = 2w + 2l

66 = 2w + 2l

Therefore, the system of linear equations that could be used to find the length and width of the rectangle will be:

l = 2w + 3 cm  

2w + 2l = 66

Hence, option D is correct.

The graph of a proportional relationship contains the point (8,4). What is the corresponding equation? Enter your answer as a fraction in simplest form by filling in the boxes.


y= — x

Answers

Given:

The graph of a proportional relationship contains the point (8,4).

To find:

The corresponding equation.

Solution:

If y in directly proportional to x, then

[tex]y\propto x[/tex]

[tex]y=kx[/tex]        ...(i)

Where, k is the constant of proportionality.

The graph of a proportional relationship contains the point (8,4).

Putting x=8 and y=4 in (i), we get

[tex]4=k(8)[/tex]

[tex]\dfrac{4}{8}=k[/tex]

[tex]\dfrac{1}{2}=k[/tex]

Putting [tex]k=\dfrac{1}{2}[/tex] in (i), we get

[tex]y=\dfrac{1}{2}x[/tex]

Therefore, the required equation is [tex]y=\dfrac{1}{2}x[/tex].

Find the slope and the y-intercept of the graph of the linear equation. 1. y=3x-7 2. y-1=-2/3x

Answers

Answer:

1) Slope: 3; y-intercept: -7

2) Slope: 2/3; y-intercept: 1

Step-by-step explanation:

y = mx + b; m is slope and b is y-intercept

1. y = 3x - 7

The equation is already in slope-intercept form, so you can find the slope and intercept.

Slope: 3

y-intercept: -7

2. y - 1 = 2/3x

For this one, you have to convert this into slope-intercept form (solving for y)

y - 1 = 2/3x

Add 1 to both sides

y - 1 + 1 = 2/3x + 1

y = 2/3x + 1

Now that the equation is in slope-intercept form, you can get the slope and y-intercept.

Slope: 2/3

y-intercept: 1

b

c
(0,2) and (-4,1)
d
(0,0) and (0,-2)

Answers

Answer:

F. (0, 5) and (-4, 2)

Step-by-step explanation:

We need to calculate the slope of each of the given sets of points until we find the set associated with a slope of 3/4:

F. (0,5) and (-4,2) As we go from (-4, 2) to (0,5), x increases by 4 and y increases by 3, so the slope is m = rise / run = 3/4. This is the line with slope 3/4.

The graph of y = f(x) is shown below. What are all of the real solutions of f(x) = 0?

Answers

Answer:

x = -4, 4

Step-by-step explanation:

Given graph in the attachment represents the function y = f(x)

Real solutions of the function means all the points where the curve of the graph either touches or crosses the x-axis.

Since, graph of the function touches and crosses at x = -4 and x = 4

Therefore, all real solutions of the function are x = -4 and x = 4
