Answer:

5x^3+6x^2+x-7

Step-by-step explanation:

f(x) = 4x^3 - 2x and g(x) = x^3 + 6x^2 + 3x - 7,

f(x) + g(x)= 4x^3 - 2x+ x^3 + 6x^2 + 3x - 7

               4x^3 + x^3 + 6x^2 + 3x- 2x - 7

Combine like terms

5x^3+6x^2+x-7

Answer:

3

Explanation:

The formula for the slope of a line is

[tex]\frac{ y_{2} -y_{1}}{x_{2} -x_{1}}[/tex]

In this case, the y2 would be 5 and the y1 would be 2

so the numerator would be 3.

The x2 would be 4 and the x1 would be 3 so the denominator would be 1.

The answer is [tex]\frac{3}{1} = 3[/tex]

Answer:

  D

Step-by-step explanation:

We assume the rotation R is counterclockwise 60°.

__

The exponent on R is the number of times it is applied. That is, R² = R(R(figure)). So, the composition is equivalent to R^(2-4) = R^-2.

When the exponent of R is negative, it is essentially the inverse function. That is, applying the function R to the result will give the figure you started with. Equivalently, it is rotation in the other direction.

  [tex](\mathcal{R}^2\circ\mathcal{R}^{-4})(\text{figure})=\mathcal{R}^{-2}(\text{figure})=\text{figure rotated $120^{\circ}$ CW}[/tex]

The point 120° clockwise from B is D.

The desired image point is D.

Answer:

The negative signs were switched.

Step-by-step explanation:

Aaron claims the same answer could also be found by adding either –5 + 3 or –3 + 5.

What is the error in Aaron’s reasoning?

The commutative property is not true for addition.

The negative signs were switched.

The numbers are not in the correct order.

The associative property was used.

Answer:

x= 5 /2 , − 4

Step-by-step explanation:

Factor and set each factor equal to zero.

Answer: x=-4, x=5/2

Step-by-step explanation:

To factor the expression, you want to break up the expression into 2 parts.

2x²+3x-20

(2x²-5x)+(8x-20)       [factor each part]

x(2x-5)+4(2x-5)         [take out x+4]

(x+4)(2x-5)                 [set each factor equal to 0]

x=-4

x=5/2

Now, we know that x=-4 and x=5/2.

Answer:

x³ + 4x² - 31x - 70

Step-by-step explanation:

Step 1: Expand (x - 5) and (x + 2)

(x - 5)(x + 2) = x² + 2x - 5x - 10 = x² - 3x - 10

Step 2: Expand (x² - 3x - 10) and (x + 7)

(x² - 3x - 10)(x + 7) = x³ - 3x² - 10x + 7x² - 21x - 70 = x³ + 4x² - 31x - 70

Answer:

Equation: y=1.5x+4          Will total $10 after 4 hours

Step-by-step explanation:

Format: y=mx+b

y is total cost

m is per hour

b is starting cost

Equation: y=1.5x+4

After 4 hours, it will be $10 because:

10=1.5x+4

subtract 4 both sides

6=1.5x

divide 6 by 1.5

4=x

Hence the 4 hours answer

Answer:

[tex]a = - \frac{1}{9} [/tex]

Step-by-step explanation:

[tex]5a - 2 = 23a[/tex]

Collect like terms and simplify

[tex] - 2 = 23a - 5a \\ - 2 = 18a[/tex]

Divide both sides of the equation by 18 and simplify

[tex] \frac{ - 2}{18} = \frac{18a}{18} \\ - \frac{1}{9} = a[/tex]

Answer:

answer. -9

Step-by-step explanation:

5a-2=23a

5a-23a=2

-18a=2

a=-18/2

a=-9

Answer:

Slope = 3

Step-by-step explanation:

Let (x1,y1) = (-3,-11) and (x2,y2) = (1,1)

Slope = y2-y1/(x2-x1)

1-(-11)/(1-(-3) = 12/4 = 3

The trigonometric expressions equal to - 1/2 is cos(120°).

For every point P (a, b) on the unit circle, – 1 ≤ a ≤ 1 and – 1 ≤ b ≤ 1, we have – 1 ≤ cos x ≤ 1 and –1 ≤ sin x ≤ 1 for all x. Also, we can define the values of a and b in different quadrants as:

First quadrant: 0 < x < π/2 ⇒ a and b are positive

Second quadrant: π/2 < x < π ⇒ a is negative and b is positive

Third quadrant: π < x < 3π/2 ⇒ a and b are negative

Fourth quadrant: 3π/2 < x < 2π ⇒ a is positive and b is negative.

We know that,

cos(180° - θ) = -cosθ

According to question,

cos(120°)

= cos(180° - 60°)

It comes in 2nd quadrant where cos is negative.

= -cos60°

= - 1/2

Hence the trigonometric expressions equal to - 1/2 is cos(120°).

Step-by-step explanation:

Answer:

A) Hypothesis: IF the new drug are given to cancer patients, THEN they will recover.

B) The experiment is testing the effect of the new drug on the recovery of cancer patients

C) The control group can be the group of patients that does not receive the new drug

D) The experimental group are the patients on which the new drug were tested on.

E) The independent variable is the NEW DRUG

F) The dependent variable is the RECOVERY OF THE CANCER PATIENTS.

Step-by-step explanation:

1) In an experiment, the hypothesis is a testable explanation given to provide a possible answer to an observed problem. In this case, a hypothesis can be: IF the new drug are given to cancer patients, THEN they will recover.

2) The experiment is conducted in order to test if the hypothesis will be ACCEPTED OR REJECTED. In this case, the experiment being conducted is to test the effect of the new drug on the recovery of cancer patients.

3) The control group in an experiment is the group that does not receive the experimental treatment, which is the new drug in this case. Hence, the control group will be the group of patients that does not receive the new drug.

4) In contrast to the control group, the experimental group is the group that receives the experimental treatment (new drug). In this case, the experimental group are the patients on which the new drug were tested on.

5) The independent variable is the variable that the experimenter manipulates or changes in the experiment. In this case, the independent variable is the NEW DRUG.

6) The dependent variable is the variable that the experimenter measures or the variable that responds to the changes made to the independent variable. In this case, the dependent variable is the RECOVERY OF THE CANCER PATIENTS.
