how do you find eqivalent expressions

First convert the equation in the form of y= mx + c

The equation will be like = y = 6x-5

value of m = 6

The slope of perpendicular line will be = -1/m = -1/6

(3w + 9) + (6w + 7) + (8w - 4) =

= 3w + 9 + 6w + 7 + 8w - 4 =

= 3w + 6w + 8w + 9 + 7 - 4 = 17w + 12

-9 ≤ x ≤ 4

it is less than or equal to -9°F, but also less than 4°F

Answer:

y ≥ -2x + 2.5

Step-by-step explanation:

It's kind of hard to tell because no points are given on the graph, but we can first find the b value of 2.5 in the equation y = mx +b  as it is the y-intercept.

Using that value, we can also recognize that at one, it looks like the y-value is .5. using our slope formula (change in y / change in x), we can plug in the two points of (0, 2.5) and (1, 0.5) to get a slope of -2.

Now that we have our equation, we can make it an inequality!  

Since the graph is shaded upwards, we know it is going to be a greater than symbol, and since the line itself solid and not dotted, we know that the points on the line are also solutions, meaning that it is also equal to the line

Hence, we get the ≥ sign.

Putting it all together, we get our final equation of y ≥ -2x + 2.5 ! :))

Answer: -$28

Step-by-step explanation: Since Monique has $12, then she subtracts $40 from that. 12 - 40 = -28.

Answer:

JL would be the total length

The Sum of JK and KL would be equal to the value of JL

4x + 3x = 42

Finding x

7x = 42

x = 42/7

x = 6

Hence,

Value of x is 6

Answer:

  G(0, 20)

Step-by-step explanation:

G = 2M -F

G = 2(7, 19) -(14, 18) = (14 -14, 38 -18)

G = (0, 20)

Additional comment

This formula for finding the end point from the midpoint and the other end can be derived from the fact that the midpoint is the average of the endpoints.

  M = (F+G)/2

  2M = F+G . . . . . multiply by 2

  G = 2M -F . . . . . subtract F

Answer:

(12x + 7)(12x - 7)

Step-by-step explanation:

144x² - 49

= (12²)x² - 7²

= (12x)² - 7²

Introducing Difference of Two Squares

= (12x + 7)(12x - 7)

Each group used 9 pictures, first divide total pictures by pictures per group to find total groups:

585 / 9 = 65 total groups.

Each group had 3 students.

Multiply total groups by students per group:

65 x 3 = 195 total students

Answer: 195 students.

The easiest fraction you could make out of this would be 37 and 45/100ths

Answer:

positive

Step-by-step explanation:

it will be a positive because the 2 numbers don't share the same positivity : meaning -2 is a negative number and 3 is a positive you add those it will be a positive

Answer:

16.80 euros.

Step-by-step explanation:

12% = 0.12

So it will now be 15 + 15 * 0.12

= 16.80.

Answer:  16.80 euros

===========================================================

Explanation:

There are two approaches

The slightly slower approach is to do this

12% of 15 = 0.12*15 = 1.80

So you get an 1.80 euro raise and the new amount you get is 15+1.8 = 16.80 euros

The shortcut is to do this

1.12*15 = 16.80

This works because increasing by 12% is the same as taking 112% of that original amount.

Answer:

x=33

Step-by-step explanation:

The angles are same side interior angles and they add to 180 degrees

x+20 + 4x-5 = 180

Combine like terms

5x + 15 = 180

Subtract 15 from each side

5x +15-15 = 180-15

5x = 165

Divide by 5

5x/5 = 165/5

x=33

Now we have to,

→ find the required value of x.

The final output will be,

→ 180°

The equation we use to find the value,

→ (x+20) + (4x-5) = 180°

Let's find the required value of x,

→ (x+20) + (4x-5) = 180°

→ 5x +15 = 180°

→ 5x = 180 - 15

→ x = 165/5

→ [x = 33°]

The value of 4x will be,

→ 4x = 4 × 33

→ 132°

Let's check whether the required value of x is correct or incorrect,

→ (x+20) + (4x-5) = 180°

→ (33+20) + (132-5) = 180°

→ 53 + 127 = 180°

→ 180° = 180°

→ LHS = RHS

Hence, 33° is the required value of x.

[tex]$X=1.5, Y=0.75$[/tex]

Step-by-step explanation:

 Let the ends of the line segment be A(-1,9) and B(3,-7)

 Divided in the ratio m:n by a point P

 By formula of coordinate geometry,

[tex]$X=\frac{5 * 3+3 *(-1)}{5+3}$[/tex]

[tex]$Y=\frac{5 *(-7)+3 * 9}{5+3}$[/tex]

 Where X and Y are the required coordinates.

 So, by calculations,

 It lies in the positive X-Y Plane.
