Abe has 150 t-shirts to sell before the playoffs begin. The table shows the linear relationship between the number of t-shirts r
Papessa [141]

Answer:

Y= -12x + 150

Step-by-step explanation:

1. You do the change in y over the change in x to get the slope.

y1 - y2 / x1 - x2 and you get the slope of -12

2. Making a point-slope form equation

y-y1=m(x-x1)

y-138= -12(x-1)

3. Turning point-slope form equation to slope-intercept

y-138= -12(x-1)

distributive property

y-138=-12x+12

add 138 on both sides

<h2><u> y= -12x+150</u></h2>

How many solutions does the system of equations have? Pls help :(
goldfiish [28.3K]

Given the system of equations below:

\large{ \begin{cases} y = 2x + 1 \\  - 4x + 2y = 2 \end{cases}}

The first equation is y-isolated so we can substitute in the second equation.

\large{ - 4x + 2(2x + 1) = 2}

Use the distribution property to expand in and simplify.

\large{ - 4x + 4x + 2 =  2} \\  \large{0 + 2 = 2 \longrightarrow 2 = 2}

The another method is to divide the second equation by 2.

\large{ \frac{ - 4x}{2}  +  \frac{2y}{2}  =  \frac{2}{2} } \\  \large{ - 2x + y = 1}

Arrange in the form of y = mx+b.

\large{y = 1 + 2x \longrightarrow y = 2x + 1}

When we finally arrange, compare the equation to the first equation. Both equations are the same which mean that both graphs are also same and intersect each others infinitely.

For more information, when the both sides are equal for equation - the answer would be infinitely many. If both sides aren't equal (0 = 4 for example) - the answer would be none. If the equation can be solved for a variable then it'd be one solution.

Answer

  • Infinitely Many

Hope this helps. Let me know if you have any doubts!

Simplify -3(x + 3) + 4x
Nadusha1986 [10]

Answer: x2 + 34x - 13

Step-by-step explanation:

STEP

1

Trying to factor by splitting the middle term

1.1     Factoring  x2+34x-13  

The first term is,  x2  its coefficient is  1 .

The middle term is,  +34x  its coefficient is  34 .

The last term, "the constant", is  -13  

Step-1 : Multiply the coefficient of the first term by the constant   1 • -13 = -13  

Step-2 : Find two factors of  -13  whose sum equals the coefficient of the middle term, which is   34 .

     -13    +    1    =    -12  

     -1    +    13    =    12  

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Final result :

 x2 + 34x - 13
