Answer:

a = -2

Step-by-step explanation:

a + 8/3 = 2/3

a = 2/3 - 8/3

a = -6/3 = -2

Answer:a=-2

Step-by-step explanation:

A+8/3=2/3

3a+8/3=2/3

Cross multiply

3(3a+8)=2(3)

9a+24=6

9a=6-24

9a=-18

a=-2

HELP MEH!!<br> THX!!! <br> MAKE SURE ITS ACTUALLY AN ANSWER!
solmaris [256]

m = \frac{29}{18}

add \frac{11}{6} to both sides

m = - \frac{2}{9} + \frac{11}{6}

we require a common denominator for both fractions before adding

multiply numerator/denominator of - \frac{2}{9} by 2

multiply the numerator/denominator of \frac{11}{6} by 3

= - \frac{4}{18} + \frac{33}{18} = \frac{29}{18}

Which statement is true regarding the graphed functions?
Luba_88 [7]

In the given graph, the two lines intersects at

x=-2

And intersection point is that point , where the y values of the two graphs are equal .

That is

f(x) = g(x)

And at x=-2, the y values are equal. THat is

f(-2) = g(-2)

So the correct option is D.

Determine the domain and range of (g ○ f)(x) if f of x is equal to 9 over the quantity x squared minus 9 end quantity and g(x) =
Bezzdna [24]

The domain is all real numbers except -6 and 0. Hence, domain D: {x ∈ ℝ| x ≠ –6, 0}

Hence the range is all real numbers except -3 and 3. Hence, range R: (–∞, –3) ∪ (3, ∞)

Given the following functions:

f(x)=\frac{9}{x^2-9}\\g(x)=x+3

First we need to get the composite function f(g(x))

f(g(x)) = f(x+3)\\f(x+3)=\frac{9}{(x+3)^2-9} \\f(x+3)=\frac{9}{x^2+6x+9-9} \\f(x+3)=\frac{9}{x^2+6x} \\

Get the domain

The domain the values of x for which the function exists. The function cannot exists at when x = -6 and x = 0

  • Hence the domain is all real numbers except -6 and 0. Hence, domain D: {x ∈ ℝ| x ≠ –6, 0}

The range is the value of y for which the function exists. The function cannot exists at when x = -6 and x = 0

  • Hence the range is all real numbers except -3 and 3. Hence, range R: (–∞, –3) ∪ (3, ∞)

Hello! I'm having a really hard time solving this by Elimination and could really use some help ​
Mamont248 [21]

Answer:

x= 3, y=0, z= 1

Step-by-step explanation:

Let's label the 3 given equations first.

2x +3y +4z= 10 -----(1)

3x +2y -4z= 5 -----(2)

x +4y +2z= 5 -----(3)

(1) +(2):

<em>This</em><em> </em><em>is</em><em> </em><em>to</em><em> </em><em>eliminate</em><em> </em><em>the</em><em> </em><em>z</em><em> </em><em>term</em><em>.</em>

2x +3y +4z +3x +2y -4z= 10 +5

5x +5y= 15

<em>Divide</em><em> </em><em>by</em><em> </em><em>5</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>

x +y= 3 -----(4)

(3) ×2:

2x +8y +4z= 10 -----(5)

(2) +(5):

<em>This</em><em> </em><em>is</em><em> </em><em>to</em><em> </em><em>eliminate</em><em> </em><em>z</em><em> </em><em>term</em><em>.</em>

3x +2y -4z + 2x +8y +4z= 5 +10

5x +10y= 15

<em>Divide</em><em> </em><em>by</em><em> </em><em>5</em><em> </em><em>throughout</em><em>.</em>

x +2y= 3 -----(6)

(6) -(4):

x +2y -(x +y)= 3 -3

x +2y -x -y= 0

y= 0

subst. y=0 into (4):

x +0= 3

x= 3

subst. x=3, y=0 into (3):

3 +4(0) +2z= 5

3 +2z= 5

2z= 5 -3

2z= 2

z= 2÷2

z= 1
