In the graph shown below, if lines 1^1 are parallel, then the slope of the line 1^2 is?

Galina-37 [17]

Answer:

<h2>Two lines are parallel if the have the same slope. Example 1: Find the slope of the line parallel to the line 4x – 5y = 12. To find the slope of this line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line 4x – 5y = 12 is m = 4/5.</h2>

The low temperature last week in Iceland was-2.25. The low temperature this week was 1.25. What was the change in temperature fr

viktelen [127]

Answer:

The change in temperature from last week to this week=3.5

Step-by-step explanation:

To get the change in temperature from last week to this week, we need to take last week's temperature and subtract it from this week's temperature.

For example;

Change in temperature=This week's temperature-last week's temperature

where;

This week's temperature=-2.25

last week's temperature=1.25

replacing;

Change in temperature=(1.25)-(-2.25)=1.25+2.25=3.5

The change in temperature from last week to this week=3.5

Which sequences are geometric? Check all that apply.

Zigmanuir [339]

Answer:

–2.7, –9, –30, –100, ...

–1, 2.5, –6.25, 15.625, ...

8, 0.8, 0.08, 0.008, ...

Explanation:

A geometric sequence is a sequence with the ratio between two consecutive terms constant. This ratio is called the common ratio.

now check all the sequence one by one.

For sequence –2.7, –9, –30, –100, ...

r = $\frac{-9}{-2.7}= 3.333$

= $\frac{-30}{-9} = 3.3333$

= $\frac{-100}{-30} = 3.3333$

We see that, all the ratios are same.

So this is geometric sequence.

For sequence –1, 2.5, –6.25, 15.625, ...

r = $\frac{2.5}{-1} = \frac{-6.25}{2.5} = \frac{15.625}{-6.25} = 2.5$

This is also geometric sequence.

For sequence 9.1, 9.2, 9.3, 9.4, ...

In this sequence, common ratio is not same.

So, it is not a geometric sequence.

For sequence 8, 0.8, 0.08, 0.008, ...

Common ratio is same so, it is geometric sequence.

For sequence 4, –4, –12, –20, ...

Common ratio is not same. So, it is not geometric sequence .
