Answer:

[3m - n = 2]

-3m - n + n = 2 + n

3m - n + 2

-3m/3 = n+2/3

m=1/3 n+2/3

Answer:

m=1/3n + 2/3

[2m + n = - 7]

-Let's solve for m.

2m+n=−7

Step 1: Add -n to both sides.

2m+n+−n=−7+−n

2m=−n−7

Step 2: Divide both sides by 2.

2m/2= −n−7/2

m= −1/2n + −7/2

Answer:

m= −1/2n + −7/2

The value of x from the equation 3x + 4 = 31 and x + 4 = 13 is 9.

3x + 4 = 31

x + 4 = 13

From equation (2)

x + 4 = 13

subtract 4 from both sides

x = 13 - 4

x = 9

Substitute x = 9 into (1)

3x + 4 = 31

3(9) + 4 = 31

27 + 4 = 31

Answer:

-11 < x < 7

Step-by-step explanation:

x² + 4x < 77

Subtract 77 from both sides

   x² + 4x - 77 < 0

To find the zero points (Roots),

Make x² + 4x - 77 = 0

Now find the factors

         x² + 11x - 7x - 77 = 0

     x(x + 11) - 7(x + 11)   = 0

               (x +11) (x - 7)  = 0

x + 11 = 0            or (x -7) = 0

     x = -11           or        x = 7

So, the solutions of  the inequality is between (-11) and 7

   -11 < x < 7

Answer:

x < –11 or x > 7 is the correct answer!!

Step-by-step explanation:

The answer above this was just slightly wrong. I took the exam and put my answer as option b and got it correct. Here is how I solved it correctly!

To solve the inequality x^2 + 4x > 77, we can factor the quadratic expression as (x - 7)(x + 11) > 0

To determine the solution, we consider the signs of each factor:

(x - 7) > 0 and (x + 11) > 0

This means x is greater than 7 or x is less than -11.

So, the simplified solution to the inequality x^2 + 4x > 77 is:

x < -11 or x > 7

Step-by-step explanation:

The shaded area is less than the equation of the line ....it is a dashed line, so the line itelf is NOT included

the equation of the line is     y =  -x + 1

so the inequality is

   y < -x+1

Answer:

y<-x+1

Step-by-step explanation:

by shading the left side of the dotted line x is negative, and the plus one is the point plotted on the dotted line, the dotted line is the cause of the < symbol, if it was a greater than or equals too the line would be solid.

Answer: y = 3/5x + 13/5

Step-by-step explanation:

To solve this you would have to use slope-point form Y − y1 = m(x − x1)

In this case, you would plugin your x and y values from your 1 point. It would look something like this. y - 2 = m(x + 1). But now the issue is we don't know our slope, To find out a slope you would use 2 - y1/x2 -x1 which would be 3/5 so, in the end, the equation would look like y - 2 = 3/5 (x + 1). Now solve for Y and your answer would be y = 3/5x + 13/5

Answer:

x = - 7 , x = 2 , x = 1

Step-by-step explanation:

note that

p(1) = 1³ + 4(1)² - 19(1) + 14 = 1 + 4 - 19 + 14 = 0

since p(1) = 0 , then x = 1 is a zero

using synthetic division

1 | 1  4  - 19    14

    ↓  1     5   - 14  

   ------------------------

     1  5    - 14   0

quotient is x² + 5x - 14

equating quotient to zero

x² + 5x - 14 = 0

(x + 7)(x - 2) = 0

equate each factor to zero and solve for x

x + 7 = 0 ⇒ x = - 7

x - 2 = 0 ⇒ x = 2

then zeros are x = - 7, x = 2 , x = 1

Answer:

Then the area of the rectangle will be

Area of the rectangle = L × W square units

A picture frame measures 16cm by 30cm on the outside, and 312cm^2 of the picture shows.

Let x be the increase in length and width. Then we have

      (16 - x)(30 - x) = 312

     x² - 46x + 480 = 312

      x² - 46x + 168 = 0

x² - 42x - 4x + 168 = 0

         (x - 42)(x - 4) = 0

                            x = 42, 4

we need the least or smallest common multiple for both numbers, 5 and 6.

this is very simple for the small numbers here, but in general we look at the prime factors of both numbers :

6 has the prime factors 2 and 3.
