Answer:

see explanation

Step-by-step explanation:

the equation of a quadratic in standard form is

ax² + bx + c = 0 ( a ≠ 0 )

2x² = 6 - x ( subtract 6 - x from both sides )

2x² + x - 6 = 0 ← in standard form with a = 2, b = 1 , c = - 6

x² - 8x = - 16 ( add 16 to both sides )

x² - 8x + 16 = 0 ← in standard form with a = 1, b = - 8 , c = 16

4x² = 144 ( subtract 144 from both sides )

4x² - 144 = 0 ← in standard form with a = 4 , b = 0 , c = - 144

x² - 2x = 24 ( subtract 44 from both sides )

x² - 2x - 44 = 0 ← in standard form with a = 1 , b = - 2 , c = - 44

2x² + 4 = 6x ( subtract 6x from both sides )

2x² - 6x + 4 = 0 ← in standard form with a = 2 , b = - 6 , c = 4

Answer: the answers are below

Step-by-step explanation:

1 meal = 2/3 of a can of wet dog food, 1/8 of a bag of dry dog food, and 3/5 a patty of special meat

Food for 1 day: 2 meals = 2(2/3) = 4/3 of a can of wet dog food, 2(1/8) = 1/4 of a bag of dry dog food, and 2(3/5) = 6/5 a patty of special meat

The trainer goes to the store and buys 24 cans of wet food, 4 bags of dry food and 3 packages of meat (3*6 = 18 patties)

He has:

there is wet food for: 24/(4/3) = 24*3/4 = 18 days

there is dry food for: 4/(1/4) = 4*4 = 16 days

there is special meat food for: 18/(6/5) = 18*5/6 = 15 days

since the minimum for 15, 16 and 18 is 15 the dog will have food for 15 days and first he will run out of special meat.

podryga [215]

Simplified expression for total amount spent is 10(2.05 + m)

Step-by-step explanation:

Step 1: Write expression for expense on joining cooking club for m months.

Expense = 8.50 + 6.25 × m

Step 2: Write expression for expense on joining movie club for m months.

Expense = 12 + 3.75 × m

Step 3: Calculate the total amount spent on both clubs

Total Amount = 8.50 + 6.25m + 12 + 3.75m = 20.5 + 10m = 10(2.05 + m)

Find the obtuse angle the line y-2x=7 makes with the x- axis

Kazeer [188]

In analytical geometry, there are already derived equations to find the distance of lines and points as well as the angle made between two lines. As special case is when the other line is one of the coordinate axis. Then, the formula can be simplified to

tan θ =m, where m is the slope of the equation

In the next step, we also incorporate operations of calculus. Since the slope is equal to Δy/Δx, this is equivalent to dy/dx in calculus. Therefore, you can find the slope by differentiating the equation in terms of x.

<span>y-2x=7
y = 2x+7
dy/dx = 2 =m

So,

tan </span>θ = 2
θ = tan⁻¹(2)
θ = 63.43°

How you know that the values of the digit in the numbers 1500,000 and 100,500 ate not the same

Sliva [168]

In this number 1500,000,

1 is at million place and 5 is at hundred thousand place

So, the value of 1 = 1 (1,000,000) = 1 million

And the value of 5 = 5 (100,000 ) = 500,000 = Five hundred thousand

In the second number 100,500

1 is at hundred thousand place and 5 is at hundred place

The value of 1 = 1 (100,000) = 100,000 = Hundred thousand

And the value of 5 = 5 (100 ) = 500 = Five hundred

Since the digits 1 and 5 both are at different places in both the numbers so 1,500,000 and 100,500 are not the same.
