A. (2m-n) is a factor.

B. (2m-n) is a term.

C. (2m-n) is a number.
D. (2m-n) is a coefficient.

Answer:

I Think option answer is (2) -6

Answer:

false

Step-by-step explanation:

Answer:

The equation given above is  sqrt (2x + 1) = 3. First, square both sides of the equation giving, 2x + 1 = 9. Solving for x in this equation gives an answer of x = 4. When we substitute x = 4 to the original equation, the number inside the radical sign is positive. Thus, x = 4 and it is a non-extraneous root.

Answer:

16 miles

Step-by-step explanation:

96 divided by 60 is 1.6, the car traveled 1.6 miles in 1 minute. 1.6 times 10 is 16, 16 miles in 10 minutes.

Answer:

26 units

Step-by-step explanation:

If point F is on the line segment EG, then EF+FG = EG

Given

FG=8,

EF=2x+4

EG=4x−10

Substitute the given values into the formula;

2x+4+8 = 4x−10

2x+12 = 4x-10

collect like terms

2x-4x = -10-12

-2x = -22

x = 22/2

x =11

Since EF = 2x+4

EF = 2(11)+4

EF = 22+4

EF = 26

Hence the numerical length of EF is 26 units

Answer:

x = -11

Step-by-step explanation:

-2(x+3)+5x = -39

distribute the -2 to what's inside the paranthesis

-2x -6 +5x = -39

combine like terms

3x - 6 = -39

add 6 to each side

3x = -33

divide each side by 3

x = -11

Answer:

p [tex]\leq \\[/tex] 8

Step-by-step explanation:

Answer:

p[tex]\leq[/tex]8

Step-by-step explanation:

Step 1- Add 7 to both sides of the inequality.

New inequality:

[tex]\frac{p}{8}[/tex] [tex]\leq[/tex]1

Step 2- Now multiply by 8 on both sides of the inequality to get your answer.

Answer:

p[tex]\leq[/tex]8

x = lbs

y = total cost

ABC shipping: $7 + $1x = y

XYZ shipping: $10 + $0.75x = y

We set each equation equal to the other.

$7 + $1x = $10 + $0.75x. Subtract $7 from both sides and subtract $0.75x from both sides

$0.25x = $3. Divide each side by $0.25.

x = 12 lbs

When a package is 12lbs the cost is the same.

Answer:

X=36

Step-by-step explanation:

Let x be the unknown number

Three quarters of a number =3x/4

Three was added =3x/4 +3

Final

3x/4 + 3= 30

Multiply through with 4

3x+ 12=120

3x=120-12

3x=108

X=108/3

X=36

Answer:

B

Step-by-step explanation:

The equation c = 100 + 5C represents the cost c of a book bag order depending on the number of bags option (B)  c=5n+100 C is correct.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

A company makes a book bag and charges a one-time design fee of $100 and then $5 for each bag made.

C is the number of the book bag.

The fixed cost/one-time design fee = $100

Total cost c = 100 + 5C

Thus, the equation c = 100 + 5C represents the cost c of a book bag order depending on the number of bags option (B)  c=5n+100 C is correct.

Step-by-step explanation:

Answer: m=1/2; b=-5

Step-by-step explanation:

We can use the given points to find slope, then use the y=mx+b equation to find the y-intercept. The formula for slope is [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex].

[tex]m=\frac{-8-(-2)}{-6-6}=\frac{-6}{-12} =\frac{1}{2}[/tex]

Now that we know m=1/2, we can use that in y=mx+b to find the y-intercept. We can use any given point to plug into x and y.

y=1/2x+b                [plug in x and y]

-2=1/2(6)+b            [multiply]

-2=3+b                   [subtract both sides by 3]

b=-5

Now, we know that b=-5.
