The right answer is C)
<em>Consistent and independent system</em> of two linear equations is a system such that there is only one solution for the system, that is, the two straight lines cross at a point. So we can analyze each case and I have attached some graphs to provided you with examples. Those graphs aren't about the equations but it's about general cases:
<em>A) </em><u><em>Consistent and dependent</em></u><em>. </em>If we divide this given equation by 2 we get the same line. (See Figure 1)
<em>B) </em><u><em>Inconsistent</em></u><em>.</em><em> </em>No solutions. (See Figure 2)
C) <em><u>Consistent and Independent</u>.</em> (See Figure 3)
D) <u><em>Consistent and dependent</em></u>. If we multiply this equation by -1 we get the same line. (See Figure 1)</span>
Answer:
see explanation
Step-by-step explanation:
Using cross- products, that is
=
then ad = bc
Given the ratios
and 
Then equating and using cross- products
If both sides equate then the ratios are equivalent
=
, then
4 × 21 = 6 × 14 ⇒ 84 = 84
Both sides are equal thus the ratios are equivalent
To solve this problem, you first need to subtract 100,034-9,348. You do this because Lexi scored that many points LOWER than Rial. You then take the answer to that subtraction problem (90,696) and add 9,749 to that answer. You do this because Susie scored 9,749 MORE than Lexi. You should get 100,435. This is Susie's score, so your final answer is 100,435 points.
Answer:
55% percentage mark up
Step-by-step explanation:
Formula = Gross profit / Cost of item * 100 First we find the Cost of item = 39.99 / 06 = 66.65 as 66.65 * 0.60 = 39.99 then we find the Gross profit 66.65 - 29.99 = 36.66 then plug into the formula 36.66/66.65 * 100 =55.0037509% = 55%
The formula of a slope:

We have the points (-8, -20) and (5, 2). Substitute:

Answer: The slope is
