Answer:

(2, 0)

Step-by-step explanation:

Given the simultaneous equation

2x-y = 4

3x+y = 6

Add both equation

2x+3x = 4 + 6

5x = 10

x = 10/5

x = 2

Substitute x = 2 into equation 1

From1 ;

2x-y = 4

2(2) - y = 4

4 - y = 4

y = 4-4

y = 0

Hence the solution to the system of equation is (2, 0)

What equation represents the relationship between“p” and “q” shown in the table?

EleoNora [17]

Answer:

$q=10p$

Step-by-step explanation:

According to the given table, the variables have a linear relation, because there's a constant change involved.

Notice that p-variable increases by one unit, while q-variable increases by 10 units. That means the ratio of change is

$r=\frac{\Delta q}{\Delta p}=\frac{10}{1}$

Then, we use one pair of elements, like (3,30), and the point-slope formula to find the equations.

$q-q_{1} =m(p-p_{1} )\\q-30=10(p-3)\\q=10p-30+30\\q=10p$

Therfore, the equation that represents the table is $q=10p$

Rewrite the expression as an algebraic expression in x.<br> tan(sin−1(x))

solmaris [256]

Let $tan^{-1} x=\alpha$
Then it can be shown by using a right-angled triangle and the rule of Pythagoras that $\alpha= tan^{-1} \frac{x}{ \sqrt{1-x^{2}} }$
Therefore
$tan(sin ^{-1} (x))=\frac{x}{ \sqrt{1-x^{2}} }$

How do i do these two

Anvisha [2.4K]

1) They are both right angle triangles

2) AE = BE
AB = AE + BE
AE = 4.2cm
AB = 4.2 + 4.2
AB = 8.4cm
