D. The graph of the system shows parallel lines.
E. The graph of the system shows perpendicular lines.
THERE CAN BE MORE THAN ONE ETC ANSWERS
Answer:
b and d
Step-by-step explanation:
The ways you can tell that there is no solution to a system of equations are:
B. The equations have the same slope and have different y-intercepts.D. The graph of the system shows parallel lines.A linear equation is represented as:
[tex]y = mx+c[/tex]
Where:
m represents the slopec represents the y-interceptWhen the equations in a system of linear equation has the same slope, then the equations are parallel, and they have no solution.
Hence, the true statements are (b) and (d)

The point (2, 18) is an ordered pair in a proportional relationship. What equations represents this relationship?
y = 1/9x
y = 18x
y = 9x
y = 2x
Answer:
y = 9x
Step-by-step explanation:
If you plug in the point into each equation, you get:
y = 1/9x
18 = 1/9 * 2
18 = 2/9
not true
y = 18x
18 = 18 * 2
18 = 36
not true
y = 9x
18 = 9 * 2
18 = 18
true, so this is the answer
y = 2x
18 = 2 * 2
18 = 4
not true

Answer:
The first one would be m^30n^20p^30
And the second one would be a^2 / d^4
Step-by-step explanation:
For 1, you have to multiply the inner exponents by the outer one so you get (m^12n^8) times (m^18n^12p^30). Then you mutiply the two together, so you add the exponents, where you get m^30n^20p^30.
For 2, since you're dividing, you have to subtract the exponents so you get a^2d^-4, but since you shouldn't have the negative you turn it into a^2 / d^4

slope is 2/3 y- intercept is -2
Answer:
y = (2/3)x - 2
Step-by-step explanation:
The equation of this line is y = (2/3)x - 2, where m is the given slope and -2 is the given y-intercept. We need only plug in the given values for m and b.
Answer:
[tex]y = \frac{2}{3} x -2[/tex]
Step-by-step explanation:
This is the slope-intercept form. The slope-intercept form is written as y = mx + b where m is the slope and b is the y-intercept. The y and x stay as they are.

There are 2 cats to 5 dogs. Which of the following is an equivalent ratio of cats to dogs?
Answer:
See below.
Step-by-step explanation:
The ratio of cats to dogs would be 2/5. This is the simplest ratio, but I assume you are looking for other ratios that are equal to 2/5
Since you did not provide choices to pick from, I can't really answer your question. But, some ratios that are equal to 2/5 are 4/10, 6/15, 8/20, and 10/25.
