Which is the best description of the equivalency of the two expressions?

Expression 1
5 x squared minus 2 x minus 4 + 6 x + 3
Expression 2
6 x squared minus 6 x + 6 minus x squared + 10 x minus 7

A.) The two expressions are not equivalent because when x = 2, the two expressions do not have the same value.

b.)The two expressions are not equivalent because when they are simplified, they do not have the same coefficients for the x squared and x terms.

c.) They are equivalent because the sum of the constants is the same in both expressions.

D.) They are equivalent because when x = 2, the two expressions have the same value.

Rectangle QRST has coordinates Q(-3, 7), R(-3, 11), S(4, 11), and T(4,7)

Dilate the rectangle by a scale factor of 3 with a center of dilation at the origin. What are the coordinates of rectangle Q’R’S’T’? Explain your reasoning. Is the dilation a reduction or an enlargement?

Answers

Q’= (-6,21) R’=(-6,33) S’=(12,33) T’=(12,21) the scale factor is 3 so you multiply the coordinates by 3. It is an enlargement

Darius created a factor tree and wrote the prime factorization of 60 shown here.

A factor tree of 60. 60 branches to 4 and 15. 4 branches to 2 and 2. 15 branches to 3 and 5.


60 = 2 × 3 × 5

What is Darius’s error?

Answers

Answer: he needs to finish factoring the 4s.

Step-by-step explanation:

4x15 is 60, so that is right, 3x5 is 15, so that’s is right, 2x2 is 4, so that is right, but he didn’t finish factoring. 1x1 is 2, so he should have 1 and 1 coming from each 2 on the tree. Hope this helps.

Rewrite the absolute value function y=|x|-3 as two linear functions, one that has the domain x<0, and one that has the domain x≥0.

Answers

seems the answer has been figured out

Two linear functions, one that has the domain x < 0 is y = - x - 3

And, one that has the domain x ≥ 0 is y = x + 3.

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

We have to given that;

The absolute value function is,

⇒ y = |x| - 3

So, The linear function which has the domain x < 0 is,

⇒ y = - x - 3

And,  The linear function which has the domain x ≥ 0 is,

⇒ y = x - 3

One of the roots of the equation x2−bx+c=0 is equal to 5. Find c in terms of b.

Answer:

c=5b-25

Step-by-step explanation:

Polynomial is an equation written as the sum of terms of the form kx^n.

where k and n are positive integers.

The value of c in terms of b is 5b - 25

What is a polynomial?

Polynomial is an equation written as the sum of terms of the form kx^n.

where k and n are positive integers.

Example:

x² + 3x + 9 is an equation.

x³ + 6x² + 6x + 8 is an equation.

We have,

x² - bx + c = 0

One of the roots of this equation is 5.

This means,

5² - 5b + c = 0

25 - 5b + c = 0

Adding 5b on both sides.

25 + c = 5b

Subtracting 25 on both sides.

c = 5b - 25

Thus,

The value of c in terms of b is 5b - 25

The table shows the approximate height of a football after it is kicked. Tell whether the rates of change for successive time intervals are constant or variable

Answers

Answer: 36, 13, -10

The rates of change are variable.

Step-by-step explanation:

The rates of changes of the heights of a football after it is kicked with respect to the time for this case are 34, 12 and -10 . The rates of changes are variable.

What is a variable and a constant?

A variable is a quantity that changes in its value, but a constant remains fixed.

How to measure the rate of change of something as some other value changes?

Suppose that we have to measure the rate of change of y as x changes, then we have:

[tex]Rate = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]

where we have

[tex]\rm when \: x=x_1, y = y_1\\when\: x = x_2, y= y_2[/tex]

Remember that, we divide by the change in independent variable so that we get some idea of how much the dependent quantity changes as we change the independent quantity by 1 unit.

(5 change per 3 unit can be rewritten as 5/3 change per 1 unit)

For this case, we get the rates as:

For rate between first two values,

[tex]Rate_1 = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{17-0}{0.5-0} = 34[/tex]

For rate between second two values,

[tex]Rate_2 = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{30-17}{1.5-0.5} = 13[/tex]

For rate between third two values,

[tex]Rate_3 = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{25-30}{2-1.5} = -10[/tex]

We see that the rate of change of height of the football considered with respect to time is changing, so its a variable.

Thus, the rates of changes of the heights of a football after it is kicked with respect to the time for this case are 34, 12 and -10 . The rates of changes are variable.
