How do you write out x <=-4

1 answer:

3 0

You can write it out multiple ways, such as x<=-4, x is (-infinity, -4], or {x | x<=4}. Even using a line, put -4 down, with a closed circle (including it means) and an arrow from there pointing left, for the included values to negative infinity.

5x - 2y = -2

Step-by-step explanation:

Slope: 5/2 and (-2,-4)

y = 5/2x+ 1

5/2x - y = - 1

2(5/2x - y) = -1*2

Zinaida [17]

Answer:

$\dfrac{5}{6}$ hour or 50 minutes

Step-by-step explanation:

Last week:

Claire mowed 5 lawns

She mowed each lawn in $\frac{7}{12}$ hour.

She spent

$5\cdot \dfrac{7}{12}=\dfrac{35}{12}=2\dfrac{11}{12}$

hours to mow 5 lawns.

This week:

Claire mowed 5 lawns

She mowed each lawn in $\frac{5}{12}$ hour.

She spent

$5\cdot \dfrac{5}{12}=\dfrac{25}{12}=2\dfrac{1}{12}$

hours to mow 5 lawns.

Difference:

$2\dfrac{11}{12}-2\dfrac{1}{12}=\dfrac{11}{12}-\dfrac{1}{12}=\dfrac{10}{12}=\dfrac{5}{6}$

hour or 50 minutes.
