Step-by-step explanation:
8/9(54x - 36) +2=-3/4(-40+ 16x) + 90x
or,432x-288+18/2 =120-48x+360x/4
or,4(42x-288+18)=2(120-48x+360x)
or,168x-1080=240-624x
or,162x+624x=1080+240
or,792x=1320
or,X=1320/792
or,X=<em>5</em><em>/</em><em>3</em>
Because it show the relationship between the x and y coordinates
Answer:
-35.7
Step-by-step explanation:
1. Plug in a and b to the equation:
7(-3.9)+2(-4.2)
2. Evaluate: -35.7
Triangle ABC has:
∡ABC = 90°
∡BAC = 45°
Therefore also ∡BCA = 45°
This means that ABC is isosceles and that each leg is:
l = √2/2 · h
Since the hypotenuse of ABC is AC = 6√2
BC = √2/2 · <span>6√2 = 6
Now, consider the triangle BCD:
</span>∡BDC = 90°
∡DBC = 60°
which means that: ∡BCD = 30°
In such triangles, the side opposite to the angle of 30° is 1/2 · h
Since the hypotenuse is BC = 6, we have:
BD = <span>1/2 </span>· 6 = 3
Hence, x = 3
