Answer:

(2,0)

Step-by-step explanation:

Hi, I believe the answer is (2,0). The solution of the two equations are represented by their intersection. By finding that point, at when x is 2, and y 0, you can find the solution. Hope this helps!

You can also find the equations of the lines, then find the solution of them, but that's slower than the previous method.

4/7<br> of a number is 36<br> What is the number?

katrin [286]

$\text{If the number is x,}\\\\~~~~~\dfrac 47 \cdot x =36\\\\\implies 4x = 36 \times 7\\\\\implies x =\dfrac{36 \times 7}4\\ \\\implies x = 9 \times 7\\\\\implies x = 63\\\\\text{Hence, the number is 63.}$

When two equal forces are inclined at an angle 2a their resultant is twice as great as

swat32

Step-by-step answer:

Referring to the attached diagram, the resultant of two forces each with magnitude F and inclined to each other at 2a equals

Ra = 2Fcos(a) ..............................(1)

Similarly, the resultant of two forces each with magnitude F and inclined to each other at 2b equals

Rb = 2Fcos(b)..............................(2)

We are given that

Ra = 2Rb ....................................(3)

Substitute (1) & (2) in (3) gives

2Fcos(a) = 2(2Fcos(b))

Expand

2Fcos(a) = 4Fcos(b)

Simplify

cos(a) = 2 cos(b) QED

Note: Please note that you might have a faster response if you posted this question in the physics or the (new) Engineering section.

4/5 of a number r is equal to 16.

amm1812

Answer:

r=20

Step-by-step explanation:

take the number you have, divide it by the numerator, and multiply it by the denominator, like shown:

4/5 of a number (r) is 16

16/4=4

4*5=20

r=20

ta-da! :P
