Solve the following system of equations by graphing.
MrMuchimi

Answer:

<h2>Graph b</h2>

Step-by-step explanation:

The equation of a linear function in slope-intercept form:

y=mx+b

m - slope

b - y-intercept

The graph of linear function is a straight line therefore we need only two points to the plotting the graph.

-4x+3y=-12\qquad\text{add 4x to both sides}\\\\3y=4x-12\qquad\text{divide both sides by 3}\\\\y=\dfrac{4}{3}x-4\\\\for\ x=0\to y=\dfrac{4}{3}(0)-4=0-4=-4\to(0,\ -4)\\\\for\ x=3\to y=\dfrac{4}{3}(3)-4=4-4=0\to(3,\ 0)

-2x+3y=-18\qquad\text{add 2x to both sides}\\\\3y=2x-18\qquad\text{divide both sides by 3}\\\\y=\dfrac{2}{3}x-6\\\\for\ x=0\to y=\dfrac{2}{3}(0)-6=0-6=-6\to(0,\ -6)\\\\for\ x=3\to y=\dfrac{2}{3}(3)-6=2-6=-4\to(3,\ -4)

Please help!!! How many coefficients does this polynomial have in its complete form, including any missing terms?
frez [133]
-5x^3 + 2x^2 + 1

a coefficient is the number that is multiplied by the variable.For instance, the coefficient of 2x is 2....because 2 (the number) is multiplied by the variable x.

so in ur problem....there are 2 coefficients..-5 and 2.

** the number 1 is not a coefficient, it is a constant...a " loner " with no variables (letters) attached.

** and if u have just the letter...such as n, the coefficient to that is 1 but the one is just not written...it is actually 1n.

okay...I am gonna shut up now :)

Historically, Australia has 300 indigenous languages. Only 90 are still spoken today. What percent have gone extinct?
shtirl [24]

Answer:

70%

Step-by-step explanation:

well first you have to take put 90 over 300, times 100

<u>90</u> <u>100</u> = 30%

300 × 1

That gives you the percentage that is spoken today.

Then you have to take away that answer from 100%

100%

<u>-</u><u> </u><u> </u><u>30</u><u>%</u>

70 %
