Y < 4x - 2......u have a slope of 4.....u have a y int (where the line crosses the y axis) at (0,-2)......and u have a < sign....meaning it is a dashed line shaded below the line

and if u want to find ur x int (where the line crosses the x axis) sub in 0 for y and solve for x...disregarding the inequality sign
y = 4x - 2
0 = 4x - 2
-4x = -2
x = -2/-4
x = 1/2.....so ur line crosses the x axis at (1/2,0)

so ur graph is : graph 3
========================
y > -x + 3.....u have a slope of -1....u have a y int at (0,3)....ur inequality sign is >....meaning it is a dashed line, because there is no equal sign...and it is shaded above the line since it is greater then

ur x int is :
y = -x + 3
0 = -x + 3
x = 3......x int at (3,0)

ok..I am having a problem with this one because none of ur graphs match this inequality...because ur line will cross the x axis at 3...and none of ur graphs show this
===================
y < -2......when u have y = a number (or <,>) this will be a horizontal line....it will go thru -2 all the way across....and since it has a < sign, it will be a dashed line with shading under the line.
so ur graph is : graph 2

A plant cell has length 6.6 times 10 Superscript negative 6 m and width 2.2 times 10 Superscript negative 6 m. What is the ratio

Vinvika [58]

The length/width ratio is 3/1 .

l = 6.6 × 10⁻⁶ m; w = 2.2 × 10⁻⁶ m

l/w = 6.6 × 10⁻⁶ m/2.2 × 10⁻⁶ m = 3/1

Pls help me with this question

Sedbober [7]

7/12, 3/4, 4/7, 5/8, 4/7

Answer:

Order from Least to Greatest

4/7 = 4/7 < 7/12 < 5/8 < 3/4

Showing Work

Rewriting as fractions if necessary:

7/12, 3/4, 4/7, 5/8, 4/7

The least common denominator (LCD) is: 168.

Rewriting as equivalent fractions with the LCD:

98/168, 126/168, 96/168, 105/168, 96/168

Ordering these fractions by the numerator in order from least to greatest:

96/168 = 96/168 < 98/168 < 105/168 < 126/168

Therefore, your input in order from least to greatest is:

Answer =======> 4/7 = 4/7 < 7/12 < 5/8 < 3/4

B): 1.35, 5/4, 1.349, 6/5, 7/6

Number of inputs ====> 5

Answer => Ascending Order: Least to Greatest =====> 7/6, 6/5, 5/4, 1.349, 1.35

C): 0.819, 0.8199, 81/100, 815/1000

Number of Inputs ======> 4

Answer ==> Ascending order (Least to Greatest ====> 81/100, 815/1000, 0.819, 0.8199

D): 3 4/7, 245/70, 3.572, 90/29

Number of Inputs: 4

Answer ==> Ascending Order(Least to Greatest) ==> 90/29, 245/70, 3.572, 3 4/7

Hope that helps!!!! : )

Find the percent of increase or decrease? 2.5y to 1.5y

horsena [70]

Answer:

From 2.5 y to 1.5 y there is a 40 % DECREASE in the value.

Step-by-step explanation:

Here, the initial value = 2.5 y

The final value of 1.5 y

Now,as Final Value < Initial Value

So, there is a DECREASE IN THE VALUE.

Now, decrease in the value = Initial value - Final Value

= 2.5 y = 1.5 y = 1 y

or, there is a decrease of ( 1 y) in the given value.

Now, Percentage decrease in the value is given as:

$\textrm{Percentage Decrease} = \frac{\textrm{The decrease in the value}}{\textrm{The initial Value}} \times 100\\ = \frac{1 y}{2.5 y} \times 100 = 40$

or, Percentage Decrease = 40%

Hence, from 2.5y to 1.5y there is a 40 % DECREASE in the value.
