Answer:

Yes, Tim was correct.

Step-by-step explanation:

It is given that Tim wrote 16 as (-2) squared 4. It means

$16=(-2)^4$

We need to check whether he is correct option not.

$LHS=16$

$RHS=(-2)^4$

$RHS=(-2)\times (-2)\times (-2)\times (-2)$

$RHS=4\times 4$

$RHS=16$

$RHS=LHS$

Since LHS is equal to the RHS, therefore the Tim was correct.

The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is four times

prohojiy [21]

Answer:

{36, 66, 78}

Step-by-step explanation:

Let the measures of the three angles be f, s and t, for first, second and third. Then s + t = 4f, t = 12 + s, and f + s + t = 180.

Subbing 12 + s for t in the first equation, we get s + 12 + s = 4f.

Subbing the same in the third equation, we get f + s + 12 + s = 180

This results in two equations in two unknowns (f and s):

2s - 4f = -12

2s + f = 168.

Let's eliminate s by subtracting the first of these two equations from the second. Doing so yields 5f = 180. Then the first angle, f, or x, is 36.

Then, from 2s + f = 168, we get 2s + 36 = 168, or 2s = 132. Thus, the second angle is s = y = 66.

The sum of the three angles must be 180. Thus, 36 + 66 + t = 180, or

102 + t = 180, or t = z = 78.

The three angles are

{36, 66, 78}.

Y - y1 = m(x - x1)
slope(m) = -3/7
(5,8)...x1 = 5 and y1 = 8
now we sub
y - 8 = -3/7(x - 5) <===

Does (2,0) work as a solution to the systems of equations to lines 3x+y=6 and 3x-y=6

fenix001 [56]

Answer:

Yes

Step-by-step explanation:

To see if (2,0) works as a solution to the systems of equations, we plug in the values of x and y and simplify. If the results are equal, then (2,0) is a solution.

3x + y = 6:

$3(2) + 0 = 6$
$6 + 0 = 6$
$6 = 6$
(2,0) is a solution to this equation.

3x - y = 6:

$3(2) - 0 = 6$
$6 - 0 = 6$
$6 = 6$
(2,0) is a solution to this equation.

Therefore, the answer is yes, it does work as a solution.
