How much solutions does this equation have?
2x+y=3
2y=-4x+6

pls answer,, show ur work, have a great day :)) !!

Answers

Answer 1

Answer:

All solutions or infinite.

Step-by-step explanation:

Turn 2y = -4x + 6 into standard form - divide by 2

Y = -2x + 3

2x + y = 3

Substitute the y equation in for y.

2x - 2x + 3 = 3

The x variables cancel out.

3 = 3

Which is true so it means all solutions.

Hope this helps.

Sonia works at a bakery. The function f(x) represents the amount of money in dollars Sonia earns per loaf, where x is the number of loaves she makes. The function g(x) represents the number of bread loaves Sonia bakes per hour, where x is the number of hours she works.

f(x) = 9x2 + 1

g(x) = the square root of two times x cubed

Find f(g(x)).

f(g(x)) = 18x3 + 1 dollars over hour
f(g(x)) = 18x3 + 1 loaves over hour
f of g of x equals the square root of the quantity 18 times x to the fifth power plus 1 loaves per hour

Let the number be (10 x + y)

Then, 10 x + y = 3 * (x + y) (given)

Or, 10 x + y = 3 x + 3 y

Or, 10 x - 3 x = 3 y - y

Or, 7x = 2 y

Or, x = 2 y / 7 ( Eq. 1)

Also, 10 x + y + 45 = 10 y + x ( given)

Or, 10 x - x = 10 y - y - 45

Or, 9 x = 9 y - 45 ( Eq. 2)

Substituting the value of x from (Eq. 1) in (Eq. 2), we have:

9 * 2 y / 7 = 9 y - 45

Or, (9 y ) - (18 y / 7) = 45

Or, 63 y - 18 y = 315

Or, 45 y = 315

Or, y = 7

From (Eq. 1),

x = 2 * 7 / 7 = 2

So, the number is 10 x + y = (10 * 2) + 7 = (20 + 7) = 27

Answer

Check:

Sum of the digits = 2 + 7 = 9

9 * 3 = 27 ✓

Adding 45 to the number 27, we get 72. So, the digits get reversed.

Now that we know the radius, r is 10. The area is

I will approximate π to 3.14 although you could do it more precise or less precise. The final answer will be 100*3.14=314 squared centimeter.

Determine the domain on which the following function is increasing. Will give brainlist if correct

Answers

Answer: D : x ∈ (1, ∞)

Step-by-step explanation:

for a function  y = f(x)

The range is the set of possible values of y.

The domain is the set of the possible values of x.

We want to find the domain on which the function is increasing.

A function is increasing if, reading from left to right, the "y" value of the function increases (or the graph goes upward)

Then we need to see on which point the graph starts going up. We can see that this happens at the vertex of the parabola, at x = 1, and it keeps increasing infinitely.

then we can write this domain as:

D : x ∈ (1, ∞)

Check:
1180/43 = 27.4418605

A division problem has 43 as its divisor. Then the value of the dividend will be 1,180.

What is Algebra?

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

The formula is given as,

Dividend = Quotient × Divisor + Remainder

A division issue has 43 as its divisor. The halfway remainder are 20 and 7. The rest of 19.

Dividend = (20 + 7) × 43 + 19

Dividend = 27 × 43 + 19

Dividend = 1,161 + 19

Dividend = 1,180

A division problem has 43 as its divisor. Then the value of the dividend will be 1,180.
