Answer:

(2x+1)(x−5)

Step-by-step explanation:

If we factor 2x² - 9x - 5 using substitution, we would have; (2x+1)(x−5).

The substitution method of factorization requires that we replace it with another variable. Thus, in the expression above, we would first determine the product of the leading coefficient, and find two numbers that add up to the coefficient of the leading term.

The last step is to group the terms and factor the greatest common factor. The result of this factorization would be:

(2x+1)(x−5)

one is the length and one is the width

Step-by-step explanation:

2x^2-7x-15

Factor

(2x      )(x      )

What are the factors of -15?  -1*15  and -3*5, 3*-5 , 1*-15

We need 2* one factor ± the other factor = -7

2*-5 +3 = -7

That means the -5 is on the outside and the +3 is on the inside

(2x +3  )(x-5)

Answer:

The problem basically is saying that find two numbers that add up to 8, where one is three times the other.

Step-by-step explanation:

The best thing to do here is to write a simple system of equations.

b+y=8

b=3y

The first equation means that the total blue paint plus the total yellow paint is equal to 8 ounces.

The second equation means that the blue paint is equal to 3 times the yellow paint.

We can isolate b in the first equation to get b=-y+8

-y+8=3y

8=4y

y=2.

So we have that she needs two ounces of yellow paint.

Therefore she needs six ounces of blue paint.

Drag the yellow bar to 2, and the blue bar to 6.

Step-by-step explanation:

V= w*h*l= 3/5 times 3/4 times 2/3 = ...

3/10 cubic in. simplified

Hope this helps :D

The volume of a cuboid is 3/10 cubic inches.

Volume is the measure of the capacity that an object holds.

Formula to find the volume of the object is Volume = Area of a base × Height.

Given that, length of a cuboid = 2/3 in., Breadth of a cuboid=3/5 in., and height of a cuboid = 3/4 in.

We know that, the volume of a cuboid = Length×Breadth×Height

= 2/3 × 3/5 × 3/4

= 1/5 × 3/2

= 3/10 cubic inches

Therefore, the volume of a cuboid is 3/10 cubic inches.

Answer:

D

Step-by-step explanation:

What you need to do is find the slope of both lines. Perpendicular lines are the negative inverse of each other. The slope of the lie between points R and F is  (2-4)/(1+9)=-1/5. Now you need to find the line where the slop is 5. If you look at D, the slope of the line those points lie on is (25-15)/(4-2)=5 which makes D the answer.

Answer:

D. (2,15) and (4,25)

Step-by-step explanation:

The slope of the line that passes through (-9,4) and (1,2) is -1/5 so in order to find the slope that is perpendicular to it, you need to find out with of these pairs of points has a slope that is the negative reciprocal of -1/5 which is 5. So the only points that have the slope of 5 are (2,15) and (4,25).

Answer:

[tex]m\angle 4 = 117\textdegree[/tex]

Step-by-step explanation:

-Both [tex]\angle 1[/tex]and [tex]\angle 4[/tex] are supplementary, which they both equal to [tex]180\textdegree[/tex]. So, to get the measurement of [tex]\angle 4[/tex], you need to subtract measure of [tex]\angle 1[/tex], from [tex]180\textdegree[/tex] :

-Both [tex]\angle 1[/tex] and [tex]\angle 4[/tex] are supplementary:

[tex]\angle 1 + \angle 4 = 180\textdegree[/tex]

-Find the [tex]m \angle 4[/tex] by subtracting the [tex]m \angle 1[/tex] from [tex]180[/tex] :

[tex]180\textdegree - 63\textdegree = 117\textdegree[/tex]

Step-by-step explanation:

The average rate of change of g over the interval [-1, 2] is -2.67.

Average rate of change of a function is defined as the rate at which the value of the function is changing with respect to the change in the input values.

Given a function g.

Given interval is [-1, 2].

Average rate of change = [g(2) - g(-1)] / [2 - -1]

                                        = (-3 - 5) / (3)

                                        = -8/3

                                        = -2.67

Hence the average rate of change is -2.67.

Answer: D. n + q = 20

5n + 25q = 300

Step-by-step explanation:

Let n represent the number of nickels that you have.

Let q represent the number of quarters that you have.

Suppose you have 20 coins. It means that

n + q = 20

The total value of the coins is $3. The value of a quarter is $0.25 and the value if a nickel is $0.05. Therefore, the equation would be

0.05n + 0.25q = 3

Multiplying both sides of the equation by 100, it becomes

5n + 25q = 300

The correct option is

D. n + q = 20

5n + 25q = 300
