Answer:

3

Step-by-step explanation:

15 - 2(7 - x) = 7

collect like terms

-2(7 - x) = 7 - 15

-2(7 - x) = -8

divide both sides by -2

7 - x = -8/-2

7 - x = 4

collect like terns

-x = 4 - 7

-x = -3

dividing both sides by -

x = 3

Find the equation of the straight line which passes through each of the following pairs of points.
Tems11 [23]

Answer:

y = 3x + 1

Step-by-step explanation:

First, find slope:

y2 - y1 / x2 - x1

10 - 4/ 3 - 1 = 6 / 2 = 3

Then, put the equation into point-slope form using the point (1, 4):

y - y1 = m(x - x1)

where m is the slope

y - 4 = 3(x - 1)

If you want to put this into slope-intercept form, it would be

y-4=3(x-1)\\y - 4 = 3x - 3\\y = 3x + 1

Kisachek [45]

Answer:

Step-by-step explanation:

Add all the beads together to get your total amount of beads (This will be your denominator)

1+2+2+1=6 beads in total

You only want to focus on the amount of green beads. (Which is 2 and that will be you numerator)

\frac{Numerator}{Demonator}=\frac{green beads}{Total amount of beads}

I need help with this?
Dmitrij [34]

el triangulo que forma el radio es un triangulo equilátero y por lo tanto el lado del hexágono sera  de la misma medida que el radio:

lado = radio = 2 cm

como hay 6 lados, lo multiplicamos por 6 :

2x6 = 12 cm

entonces el perímetro del hexágono es 12 cm

<h3>Answer : y = ⅚x - 3</h3>

════════════════════

<h3>Known</h3>

x1 = 6

y1 = 2

x2 = (-6)

y2 = (-8)

════════════════════

<h3>Question</h3>

Equation of the line (y = mx + c)

════════════════════

<h3>Way to do</h3>

#First, you find the gradient (m)

m =  \frac{y2 - y1}{x2 - x1}  =  \frac{(( - 8) - 2)}{(( - 6) - 6)}  =  \frac{( - 10)}{( - 12)}  =  \frac{5}{6}

#Now use the formula of equation of the line

y - y1 = m(x - x1)

y - 2 = ⅚(x - 6)

y - 2 = ⅚x - 5

y = ⅚x - 5+2

y = ⅚x - 3
