Actually, I think your question is wrong, as,

Y and Y won't come...

Pls rewrite the question and I will answer, ok?

Thank you

And

Please correct the question

Analyze Mathematical Relationships (1)(F) Suppose the measures of ∠1 and ∠2 are in a 4 ∶ 11 ratio. Find their measures. (Diagram

Gekata [30.6K]

If the angles are complementary, we have that:

The measure of angle 1 is of 24º.
The measure of angle 2 is of 66º.

-----------------

If two angles are complementary, the sum of their measures is 90º.
In this problem, we suppose that angles 1 and 2 are complementary, thus:

$m_1 + m_2 = 90$

-----------------

The measures of angle 1 and angle 2 are in a 4:11 ratio, thus:

$m_1 = \frac{4}{4+11} = \frac{4}{15}(m_1 + m_2)$

$m_2 = \frac{11}{4+11} = \frac{11}{15}(m_1 + m_2)$

-----------------

Considering $m_1 + m_2 = 90$

$m_1 = \frac{4}{15}(m_1 + m_2) = \frac{4}{15} \times 90 = 4 \times 6 = 24$

$m_2 = \frac{11}{15}(m_1 + m_2) = \frac{11}{15} \times 90 = 11 \times 6 = 66$

The measure of angle 1 is of 24º.

The measure of angle 2 is of 66º.

How do you solve this using elimination? y=-3x+2 Y=2x-3

Vera_Pavlovna [14]

Y+3x=2----equation1
y-2x=-3-----equation 2

e1-e2
(y+3x)-(y-2x)=2-(-3)
y+3x-y+2x=5
5x=5
x=1
sub x=1 into equation 1
y+3(1)=2
y=-1

Find the indicated derivative.

Dahasolnce [82]

Oof, division rule:
(f/g)'=(f'g-fg')/g^2
Let (9t-8)^6=f and t+2=g
Thus we get
(9*6(9t-8)^5*(x+2)-(9t-8)^6)/(x+2)^2
(54(9t-8)^5*(x+2)-(9t-8)^6)/(x^2+4x+4)

I'm not sure how much I'm supposed to simplify this...
