I need help guys I don’t understand this problem

Tom [10]

Answer:

75º

165º

15º

255º

Explanation:

75º because half a circle is equal to 180º.

You know it is 165º because of the same reason.

You get the 15º from knowing that opposite angles are equal.

255º is a case of adding the angles.

Help help math please please

$\underline{\underline{\large\bf{Solution:-}}}\\$

The standard form of a line is given by -

$\green{ \underline { \boxed{ \sf{Ax+By=C}}}}$

where

A= integer
x = x-intercept
B= integer
y = y-intercept
C = constant

<h3><u>Given Equation: - </u></h3>

$\begin{gathered}\\\implies\quad \sf y = -\frac{5x}{4} -1 \\\end{gathered}$

Arranging equation in standard form -

$\begin{gathered}\\\implies\quad \sf y = -\frac{5x}{4} - \frac{1}{1} \quad (1 = \frac{1}{1})\\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf y = -\frac{5x}{4} - \frac{1 \times 4}{1 \times 4} \\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf y = -\frac{5x}{4} - \frac{4}{4} \\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf y = \frac{-5x-4}{4} \\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf 4y = -5x-4 \\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf 4y +5x =-4 \\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf 5x +4y=-4 \\\end{gathered}$

Comparing with standard form of line -

A = 5
B = 4

Thus , 5 is our required answer.

2x -4y=8 and 3x + 6y = 36

Harlamova29_29 [7]

Answer:x=8 and y=2

Step-by-step explanation:

To find 2x-4y=8 and 3x+6y=36

Solve simultaneously

Using elimination method

6x-12y=24

6x+12y=72

To eliminate x

-24y=-48

Divide through by -24

y=2

To get x

Substitute for y in equation 1

2x-4(2)=8

2x=8+8

2x=16

Divide through by x

x=8
