X + 3x = 12

(Or 4x=12)

the first x is the number of girls then the second x is the girls times 3, which is how many boys there are.

One angle be x

other is 2x-6

ATQ

$\\ \sf\longmapsto x+2x-6=90$

$\\ \sf\longmapsto 3x-6=90$

$\\ \sf\longmapsto 3x=96$

$\\ \sf\longmapsto x=32$

$\\ \sf\longmapsto 2x-6=2(32)-6=58°$

Which of the following equations represents a line that passes through the points

Xelga [282]

Answer:

C) I only

Step-by-step explanation:

( -1, -2) and (0,4)

Slope:

m=(y2-y1)/(x2-x1)

m=(4+2)/(0+1)

m=6/1

m=6

Slope-intercept:

y - y1 = m(x - x1)

y + 2 = 6(x + 1)

y + 2 = 6x + 6

y = 6x + 4

y - 16 = 6(x - 2)

y - 16 = 6x - 12

y = 6x + 4

How do you solve 7.2>0.9(n+8.6)

labwork [276]

7.2>0.9(n+8.6)
multiply 0.9 by all in parentheses

7.2> (0.9*n) + (0.9*8.6)
7.2> 0.9n + 7.74

subtract 7.74 from both sides
-0.54> 0.9n

divide both sides by 0.9
-0.6> n

ANSWER: -0.6> n

Hope this helps! :)

Find the values of x when y=1

kirill [66]

Answer:

$x=1+\sqrt{5}, 1-\sqrt{5}$

Step-by-step explanation:

$x^{2} -2x-4=0$
$(x-1)^{2} -1-4=0$
$(x-1)^{2} -5=0$
$(x-1)^{2} =5$
$x-1=\sqrt{5} ,-\sqrt{5}$
$x=1+\sqrt{5} , 1-\sqrt{5}$

<u>FINAL ANSWER</u>

$x=1+\sqrt{5} , 1-\sqrt{5}$

<u><em>In Decimal Form (Rounded to 3 significant figures)</em></u>

<em>x≈-1.24, 3.24</em>
