Answer:

First number =26

Second number =49

Step-by-step explanation:

Question:

The sum of two numbers is 75. The second number is 3 less than twice the first. Find the numbers.

Given:

Sum of two numbers = 75

The second number is 3 less than twice the first.

To find the numbers.

Solution:

Let the first number be = x

Let second number be = y

The sum equation can be given as:

x+y=75

It is given that the second number is 3 less than twice the first.

This can be given as:

y=2x-3

Substituting the value of y in terms of x in the sum equation.

x+(2x-3)=75

Combining like terms.

3x-3=75

Adding 3 both sides.

3x-3+3=75+3

3x=78

Dividing both ides by 3.

\frac{3x}{3}=\frac{78}{3}

x=26

Substitution x=26 in the second equation to find y.

y=2(26)-3\\y=52-3\\\therefore y=49

Thus, first number =26 and second number =49.

How to factor out a polynomial with a 3rd degree.
IRISSAK [1]

Answer:

How to factor out a polynomial with a 3rd degree-• well here is a For example, let G(x) = 7x³ – 125. Then factoring this third degree polynomial relieve on a differences of cubes as follows: (2x – 5) (4x² + 20x + 25), where ²x is the cube-root of 8x³ and 5 is the cube-root of 1256

What does the transformation f(x) --> -f(x) do to the graph of f(x)
mixer [17]

Answer: D) Reflect over x-axis

=======================================================

Explanation:

When we do this type of reflection, a point like (1,2) moves to (1,-2).

As another example, something like (5,-7) moves to (5,7)

The x coordinate stays the same but the y coordinate flips in sign from positive to negative, or vice versa.

We can say that (x,y) \to (x,-y) as a general way to represent the transformation. Note how y = f(x), so when we make f(x) negative, then we're really making y negative.

If we apply this transformation to every point on f(x), then it will flip the f(x) curve over the horizontal x axis.

There's an example below in the graph. The point A(2,8) moves to B(2,-8) after applying that reflection rule.

SUPER URGENT!!!!!!!! I NEED HELP!!!!!1 PLSSSS!!!!!Use the linear combination method to solve the system of equations. Explain ea
Vedmedyk [2.9K]

Answer:

x=-3,y=-2

Step-by-step explanation:

Given 2 expressions

S1:3x-8y=7

S2:x+2y=-7

Write one equation in terms of any variable (x or y)

Here I am writing S1 in terms of y

3x-8y=7\\3x-7=8y\\y=\frac{3x-7}{8}

Substitute this value of y as the value of y in S2

⇒x+2y=-7\\x+(\frac{3x-7}{8} )\times2=-7\\8x+6x-14=-56\\14x=-42\\x=-3

Therefore x=-3

Substitute this value of x in any of the expressions S1 or S2

Here i am substituting in S2

⇒x+2y=-7\\-3+2y=-7\\2y=(-7+3)\\2y=-4\\y=-2

Therefore x=-3 and y=-2
