Answer:

Simply here we use system of 2 equations.

Step-by-step explanation:

Let x be the cost of one small shirt and let y be that of one large shirt.

(4x +14y =210) (-3)

12x +11y =110

-12x - 42y= -630 note:cross 12x and - 12x

12x +11y =110

__________

-42y +11y = - 630 +110

-31y = -520

Y=520/31

Replace y in second equation:

12x +11y =110

12x +11(520/31) =110

12x +5720 =110

12x =110 - 5720/31

X= - 385/62

So one small shirt costs - 385/62 $

And a large one costs 520/31 $

Though I think there's something wrong in this problem since i verified my answer using calculator the same prices are obtained and as u see the cost of a small shirt is negative which is unbelievable.. So plz make sure from anyone else. I tried my best to help.

Which input value produces the same output value for the two functions ​
Lady bird [3.3K]

Answer:

Completion to the first table for f(x)=\frac{2}{3} x+7 is {-1, 1, 3, 5}

Completion to the second table for g(x)=2x+16\\ is { -8, -2, 4, 10}

the option is x=-6

Step-by-step explanation:

\frac{2}{3} (-12)+7= -1

\frac{2}{3} (-9)+7=1

\frac{2}{3} (-6)+7=3

\frac{2}{3} (-3)+7=5

2(-12)+16=-8

2(-9)+16=-2

2(-6)+16=4

2(-3)+16=10

Hope this helps and is correct.

What is the slope of a line that is perpendicular to the line 2y – 3x = 8?
GarryVolchara [31]

Answer:

= \frac{3}{2}

Step-by-step explanation:

y = mx + c

Here,

<h2>m => slope</h2><h3>c => intercept</h3>

In this equation ,

2y - 3x = 8

to find the value of m or the value of slope we have to solve for y

<em>Let's</em><em> </em><em>solve</em><em>,</em>

<em>2y - 3x = 8 \\ 2y = 8 + 3x \\  \frac{2y}{2}  =  \frac{8 + 3x}{2}  \\ y = 4 +  \frac{3x}{2}  \\  y =  \frac{3x}{2}  + 4</em>

<em>So</em><em>,</em><em> </em><em>t</em><em>h</em><em>e</em><em> </em><em>slope</em><em> </em><em>is</em><em>,</em>

<em>= \frac{3}{2}</em>

3x + 10 = 5(x – 17)<br> how do i solve this?<br> any easy examples?
Andreas93 [3]

Answer:

x= 95/2  or  x=47.5  or   47 1/2

Step-by-step explanation:

3x + 10 = 5(x - 17)

First Step:

multiply and combine the right side (parentheses)

5 times x = 5x         5 times -17 = -85

3x + 10 = 5x -85

Second Step:

Add like terms ----> which is: 3x and 5x -----10 and -85

BUT since you only want one x on one side, you combine x first.

3x + 10 = 5x -85

-5x         -5x

-2x + 10 = -85

NOW

Third Step:     Add the integers---> 10 and -85

you want to get 10 on the same side as the -85, so you subtract it from BOTH sides.

which brings you:

-2x + 10 = -85

       -10    -10

<u>                        </u>

NOW that we've subtracted -10 from -85 it's technically just adding 85 and 10 then putting a negative sign on it.

so now we have:

-2x = -95

Step Four:

divide -2 from each side to get X alone

<u>-2x</u> = <u>-95</u>

-2      -2

ANSWER:

x=47.5
