VMariaS [17]
4x the square root of three. A 30 60 90 right triangles’ legs are in a ratio of sqrt3/2:1/2:1. Since 1 is the part of the ratio representing the longest side, and our longest side is 8, our new ratio for our 30,60 90 triangle is 4xsqrt3:4:8. Since 4xsqrt3 is the longest leg (leg of length 4 being the other), 4xsqrt3 is the longest leg

3/2x - 2/3x=2
LekaFEV [45]

Answer

x = 0  \: or \: 4.17 \times  {10}^{ - 1} ( 5 /12 )

\frac{3}{2x}  -  \frac{2}{3x}  = 2

multiplying the denominators to get the L.C.M since there is no common factor.

2x \times 3x = 6 {x}^{2}

as the L.C .M

so now the general equation becomes

\frac{ \frac{3}{2x}  -  \frac{2}{3x} }{6 {x}^{2} }  = 2

\frac{9x - 4x}{6 {x}^{2} }  = 2

5x =  6 {x}^{2}  \times 2

5x = 12 {x}^{2}

12 {x}^{2}  - 5x = 0

factorizing x

x(12x - 5) = 0

x = 0

12x - 5 = 0

12x = 5

x =  \frac{5}{12}

x = 0.416

x = 4.17 \times  {10}^{ - 1}

Which of the following represents the graph of f(x) = 2x − 5?
iragen [17]

it's going up and to the right (slope of 2/1 or up 2 right 1) through the point 0,-5 as you set x to 0 to get f(x)=2(0)-5 , f(x)=0-5, f(x)=-5. getting points 0,-5

Solve the inequality:<br> 6(2y - 4) + 2.6 &gt; 14.7
aleksandr82 [10.1K]

Answer:

y > 3.0083

Step-by-step explanation:

6(2y-4) +2.6 >14.7

=6 ×2y +6(-4) +2.6 >14.7

=12y - 24 + 2.6> 14.7

And then collect like terms

12y > 14.7 +24 -2.6

12y > 38.7 - 2.6

<u>12y</u> > <u>36.1</u>

12. 12

y > 3.0083
