Answer:

Step-by-step explanation:

GHJ looks like it on 112 degrees.

IHJ is an acute angle so smaller than 90 degrees. I cant see the numbers there but I'm guessing its about 68 degrees.

GHJ + IHJ= 180

they should equal 180 degrees when added together.

Write the equation of the line, in standard form that has an x intercept at (3,0) and y

Nataly [62]

x intercept=a=3
y intercept=b=-2

We need the normal form first

$\\ \rm\bull\rightarrowtail \dfrac{x}{a}+\dfrac{y}{b}=1$

$\\ \rm\bull\rightarrowtail \dfrac{x}{3}-\dfrac{y}{2}=1$

Multiply by 6to bring standard form

$\\ \rm\bull\rightarrowtail 2x-3y=1$

$- (4x - 15) \geqslant - 9(3 + x) \\ - 4x + 15 \geqslant - 27 - 9x \\ - 4x + 9x \geqslant - 27 - 15 \\ 5x \geqslant - 42 \\ x \geqslant - 8 \dfrac{2}{5}$

$21 + x > 2( - 2 - 5x) + 6x \\ 21 + x > - 4 - 10x + 6x \\ x + 10x - 6x > - 4 - 21 \\ 5x > - 25 \\ x > - 5$

Hope this helps. - M
