Answer: The answer would be letter A

slope (m)=-9/2

intercept on x-axis=56/9

intercept on y-axis=28

Explanation:

18x+4y=112

(18x)/112+(4y)/112=1

(x/1)/(56/9)+y/28=1

intercept on x-axis=56/9

intercept on y-axis=28

now, 4y=-18x+112

y=-9/2x+28

so, slope (m)=-9/2

Step-by-step explanation:

Move all terms that don't contain y to the right side and solve.

y = 28 − (9 x) /(2)

Snezhnost [94]

Answer:

$\frac{ { - 155}^{4} }{ {19}^{2} } \div { (\frac{155}{19} }) ^{3} = \\ \frac{ { - 155}^{4} }{{19}^{2} } \div \frac{ {155}^{3} }{ {19}^{3} } = \\ \frac{ { - 155}^{4} }{ {19}^{2} } \times \frac{ {19}^{3} }{ {155}^{3} } = \\ - 155 \times 19 = - 2945$
