Y= − 7x y= 4x+22 Solve the system by substitution

Answers

Answer:

x = -2 u got this

Step-by-step explanation:

-7x = 4x + 22

-11x = 22

x = -2

Easy bro

Final answer:

To solve the system of equations by substitution, solve one equation for one variable and substitute the expression into the other equation. In this case, solve the first equation for y, then substitute that value of y into the second equation. Solve for x and substitute the value back into the first equation to find y. The solution to the system of equations is x = -2 and y = 14.

Explanation:

To solve the system of equations by substitution, we need to solve one equation for one variable and substitute that expression into the other equation.

In this case, we can solve the first equation for y:

y = −7x

Now we substitute this value of y into the second equation:

−7x = 4x + 22

Next, we solve this equation for x:

−7x - 4x = 22

-11x = 22

x = -2

Finally, we substitute this value of x back into the first equation to find y:

y = -7(-2)

y = 14

Therefore, the solution to the system of equations is x = -2 and y = 14.

If the probability that the Seahawks will win any given game is 0.6, the probability that they will lose three games in a row is _? Write your answer as a decimal.

Answers

-- If the probability of winning any given game is 0.6,
then the probability of losing that game is 0.4 .

The probability of losing Game #1  =  0.4 
The probability of losing Game #2  =  0.4
The probability of losing Game #3  =  0.4

The probability of all 3 events occurring  =  (0.4) · (0.4) · (0.4)

                                                           =  (0.064)  =  6.4%


Subtract these polynomials. (3x2 + 3x + 3) - (x2 + 2x + 3) =

A. 2x2 + x
B. 2x2 + 5x
C. 2x2 + 5x + 6
D. 2x2 + x + 6

Answers

Answer:

2x^2+1x

Step-by-step explanation:

Subtract these polynomials.  

(3x^2 + 3x + 3) - (x^2 + 2x + 3)

To subtract, we multiply negative sign inside the second parenthesis

3x^2 + 3x + 3-x^2 - 2x - 3

To subtract the polynomials we combine like terms

3x^2-x^2+ 3x- 2x+3-3

2x^2+1x

3x^2 -x^2= 2x^2
3x-2x=x
3-3=0

The answer is A.

When June went to a grocery store, 10% of the total amount she paid was spent on ice cream. Her total bill was40. How much money did June spend on ice cream?

Answers

June spent 20$ on ice cream.

Answer:

4

Step-by-step explanation:

Given f(x)=x^2+3 and g(x)=x+5/x. Find (g o f)(4)

Answers

To find g(f(4)), work from the inside out.

f(4) is 4^2+3, or 16+3, or 19.  Now, we must find g(19).

This is 19+5/19.  This is already a mixed number, though if you want an improper fraction solution, we have:

361/19+5/19

Which simplifies to:

366/19

Therefore, 366/19 is the answer.

For every 3.3 km rock is buried, the pressure placed upon it increased 0.1 gigapascals. If rock undergoing metamorphosis is buried at 16 km what is the pressure placed on that rock?

Answers

For every 3.3 km rock is buried, the pressure placed upon it increased 0.1 Giga pascals.

We need to find the pressure placed on that rock at 16 km.

Let us divide 16 km by 3.3 first to find the number of 0.1 Giga pascals would be there.

16/3.3.

On dividing 16 by 3.3, we get 4.8485.

In order to find the number the pressure placed on that rock, we need to multiply 0.1 by 4.8485, we get

0.48485 Giga pascals.

Therefore,  if rock undergoing metamorphosis is buried at 16 km, 0.48485 Giga pascals is the pressure placed on that rock.
