Answer:

Step-by-step explanation:

if the system of linear equation has no solution means that the lines do not intersect so they to not have any points in common ( there are no points that belong to both lines in the same time)

Think of equation as a rule and system of equation as two or more rules that have to be followed in the same time .

If you are asked to look in a parking lot full of cars and find what cars have

rule 1 -red color ( equation 1) and rule 2- is a truck ( equation 2) the cars you find are the solution of this system because the rules are true in the same time

What is the slope of the line?

Zolol [24]

Answer:

$-\frac{3}{2}$

Step-by-step explanation:

First, find 2 points on the graph where the line intersects.

For this example, let's use (2, -1) and (4, -4). Find the slope using the rise over run equation. See below:

$Slope = \frac{rise}{run} = \frac{(2, -1)}{(4, -4)} = \frac{y2 - y1}{x2 - x1} = \frac{(-4 + 1)}{(4-2)} = -\frac{3}{2}$

Assume that t varies jointly as r and q2². If t=320 when r=5 and q = 4, what is the value of q when r= 1 and t= 196?

Harrizon [31]

Step-by-step explanation:

$t = k(r)( {q}^{2} )$

$320 = k(5)( {4}^{2} )$

$320 = 80k$

$k = 4$

$196 = 4(1)( {q}^{2} )$

$49 = {q}^{2}$

$q = 7$

What number is 120% of 70

kaheart [24]

70/x=100/120
(70/x)*x=(100/120)*x - we multiply both sides of the equation by x
70=0.833333333333*x - we divide both sides of the equation by (0.833333333333) to get x
70/0.833333333333=x
84=x
x=84

now we have:
<span>120% of 70=84</span>
