What is 2x + 4 < 16

Mathematics
1 answer:
harina [27]2 years ago
7 0

Answer:

x<6         just letting you know that / is not meant for division it means a fraction bar

Step-by-step explanation:

1. Group all constants on the right side of the inequality

2x+4<16

Subtract  from both sides

(2x+4)-4<16-4

Simplify the arithmetic

2x<16-4

Simplify the arithmetic

2x<12

2. Isolate the x

2x<12

Divide both sides by 2

(2x)/2<12/2

Simplify the fraction

x<12/2

Find the greatest common factor of the numerator and denominator

x<6*2/1*2

Factor out and cancel the greatest common factor

x<6

3. Solution on a coordinate plane

Solution: x<6

Interval notation:

(-∞,6)

Laura says that the distance between (4,-2) and (4,-7) in the coordinate plane is equal to |-2-(-7)|units Ryan say that the dist
son4ous [18]

Answer:

Both are correct.

Step-by-step explanation:

In the point (4,-2) and (4,-7), the x-coordinates are same. So, the distance between these points is the absolute difference between the y-coordinates of these points.

Distance=|-2-(-7)|=5\text{ units}

So, Laura is correct.

In the point (2,3) and (-9,3), the y-coordinates are same. So, the distance between these points is the absolute difference between the x-coordinates of these points.

Distance=|2-(-9)|=|2+9|=11\text{ units}

So, Ryan is correct.

Hence, both are correct.

Can someone please help?
Alexus [3.1K]

Answer:

L = 12

W = 8

Step-by-step explanation:

Area = L*W

L = W + 4

W = W

Area = 96

W ( W + 4) = 96

w^2 + 4W = 96

w^2  + 4w - 96 = 0

(w - 8)(w + 12) = 0

Only w - 8 = 0 will work

w - 8 = 0                       Add 8 to both sides

w = 8

w + 12 = 0 will not work because you have to subtract 12 from both sides to get the value for w.

w = - 12 which has no meaning for garden plots.

So the width = 8 and the length = w + 4 = 8 + 4 = 12
