Please help! I only need the equations not the graphing​

Mathematics
1 answer:
Anvisha [2.4K]3 years ago
6 0

Answer:

x + y ≥ 4

8x + 10y ≤ 70

Step-by-step explanation:

1. State the variables

According to the graph, "Number of green towels" is on the x-axis, and "Number of blue towels" is on the y-axis, so:

let x be the number of green towels.

let y be the number of blue towels

<u />

2. <u>Write an equation for the total number of towels</u>.

The sum of number of green towels and the number of blue towels is the total number of towels.

x + y ≥ 4

"She wants to buy at least 4 towels" means she needs 4 or more. Use the ≥ symbol instead of > (which would mean more than 4 towels, not only 4).

3. <u>Write an equation for the money</u> she will spend.

Multiply each variable by the cost of the towel colour. Add them together. Equate the total as 70 because she is only willing to spend 70.

8x + 10y ≤ 70

"She does not want to spend more than $70" means she is willing to spend 70, but no more. This is why we use ≤ and not < (which would mean she would not spend 70, only less than 70).

The equations are x + y ≥ 4 and 8x + 10y ≤ 70.

An object is launched at 29.4 meters per
Lerok [7]

Answer:

The reasonable domain for the scenario is option 'a';

a) [0, 7]  

Step-by-step explanation:

For the projectile motion of the object, we are given;

The speed at which the object is launched, v = 29.4 meters per second

The height of the platform from which the object is launched, h = 34.3 meter

The equation for the height of the object as a function of time 'x' is given as follows;

f(x) = -4.9·x² + 29.4·x + 34.3

The domain for the scenario, is given by the possible values of 'x' for the function, which is found as follows;

At the height from which the object is launched, x = 0, and f(x) = 34.3

At the ground level to which the object can drop, f(x) = 0

∴ f(x) = -4.9·x² + 29.4·x + 34.3 = 0

-4.9·x² + 29.4·x + 34.3 = 0

By the quadratic formula, we have;

x = (-29.4 ± √(29.4² - 4 × (-4.9) × 34.3))/(2 × (-4.9)

∴ x = -1, or 7

Given that time is a natural number, we have the reasonable domain for the scenario as the start time when the object is launched, t = 0 to the time the object reaches the ground, t = 7

Therefore, the reasonable domain for the scenario is; 0 ≤ x ≤ 7 or [0, 7].

If you have 3x + y = 9 write it in slope intercept form... what is the slope, y intercept?
ladessa [460]

Step-by-step explanation:

given

3x + y = 9

Writing In slope intercept form , y = mx + c

y = -3x + 9

comparing the given equation with y = mx + c

slope (m) = - 3

y-intercept (c) = 9

Hope it will help :)

Which inequality defines the problem below ?
Likurg_2 [28]

Answer:

D

Step-by-step explanation:

so total travel by x bikers = 50 multiplied by x = 50x

According to the question

 50x = 560

dividing 560 miles by 50 miles per biker give ya 11.2 or approximately 12 bikers.
