X - 2y &lt; 2<br> graph the inequality
Korvikt [17]

Answer:

y > 1/2x - 1

First, draw the dashed line y = 1/2x - 1 (slope intercept ; y = mx + b).

Start at -1 on the y-axis, and continue going 2 units to the right, and 1 unit up for the right side of the graph.

Then starting at -1 on the y-axis, continue going 2 units to the left, and 1 unit down for the left side of the graph.

Explanation:

Convert standard form (Ax + By = C) by isolating y from the rest of the equation.

Ax + By = C → y = -Ax/B + C/B → y = mx + b.

Given a standard form equation in inequality form,

x - 2y < 2.

Set it to slope-intercept as an inequality to find the slope and y-intercept.

When negating (making opposite) a variable, you flip the inequality.

x - 2y < 2 → x - 2y - x < 2 - x → -2y < -x + 2 → 2y > x - 2 → <u>y > 1/2x - 1</u><u>.</u>

There is a bag with only red marbles and blue marbles.
mote1985 [20]

Answer:

red marbles

Step-by-step explanation:

Since the formula is;

Probability = number of required outcome

_______________________

number of possible outcome

3/8. = x/56

8x. = 168

x. 21 ( number of blue marbles)

Therefore if the total marbles = 56 and 21 of the marbles are blue then to get the red marbles

= 56 - 21

= 35

if a car travels 370.3 miles on 52 liters of gas, how many liters of.gas.will take to go 722 miles.if the car travels at the sam
blsea [12.9K]

Answer:

101.4 liters.  

Step-by-step explanation:

First of all we will find mileage of car.  

\text{Mileage of car}=\frac{\text{Total distance traveled}}{\text{Total amount of fuel}}

\text{Mileage of car}=\frac{370.3\text{ miles}}{52\text{ liters gas}}

\text{Mileage of car}=7.12115\frac{\text{ miles}}{\text{ liters gas}}

We can see that car travels at the rate of 7.12 miles per liter gas. Now let us find amount of gas needed to travel 722 miles at the same rate.

\text{Amount of gas needed}=\frac{722}{7.12}

\text{Amount of gas needed}=101.388

Therefore, it will take 101.4 liters of gas to travel 722 miles.

7^8 divide by 7y =7^6 find the value of y
lisabon 2012 [21]
Answer: y = 7

Explanation:

7^8/7y = 7^6
7^7/y = 7^6
In order for 7^7 to become 7^6 you need to divide by 7

Which mean y = 7

So that:
7^7/7= 7^6
7^6 = 7^6
