Answer:

I'm going to assume that you meant y=3x-8 and y=-4

This means that you would substitute -4 into the spot of y which gives you -4=3x-8. Once solved you would receive x=4/3.

Hope I helped have a nice day :)

The graph of f(x)=3•2^x -3 is shown below. G(x) is a transformation of f(x). How would you write the equation for the function g

Bezzdna [24]

Answer:

Step-by-step explanation:

To find the appropriate equation, notice the red graph has shifted up about 6 units. This means that $3*2^x-3$ which is shifted by -3 will move 6 up. -3+6= 3. This means the function will have +3. Only B and C are options. Now test a point. Notice the red function crosses the y-axis at about 5 or 6 when x=0.

$g(x) = 2^x+3\\g(0) = 2^0+3\\g(0)=1+3\\g(0)=4$

This function doesn't match.

$f(0) = 3*2^0+3\\f(0) = 3*1+3\\f(0)=6$

This function matches. Option C is correct.

the company started with 120 employees the first year, and added 30 employees each year for five years?

It would be 270 because 30x5+120=270

I need help with these 4 questions on my math homework! I have some examples with it but I still don't know how to do them... (S

Step-by-step explanation:

For equation N°2

$-x-3 = 0\\$

Solving algebraically:

$-x + x -3 = x$ (Sum x on both sides of the equation)

$-3 = x\\$

Resolving graphically:

x = -2 --------- - (- 2) -3 = -1 pto (-2, -1)

x = -4 ---------- - (- 4) -3 = 1 pt (-4.1)

x = -3 --------- - (- 3) -3 = 0 pt (-3.0) Solution

The graphic is shown in the attached image. The red dot in the graph represents the solution

For equation N° 4

$9x +3 = 0\\$

Solving algebraically:

$9x+3 -3 = -3$ (Sum -3 on both sides of the equation)

$9x =-3$

$\frac{9x}{9}=\frac{-3}{9}$ (divided by 9 on both sides of the equation)

$x =\frac{-3}{9}$ (simplifies the fraction)

$x =\frac{-1}{3}$

Resolving graphically:

x = 1 --------- 9 (1) +3 = 12 pt (1.12)

x = -1 --------- 9 (-1) +3 = -6 pto (-1, -6)

x = -1 / 3 -------- 9 (-1/3) +3 = 1 pt (-1 / 3.0) Solution

The graphic is shown in the attached image. The red dot in the graph represents the solution

For equation N°. 6.

$4x + 11 = 4x-24\\$

Solving algebraically:

$4x -4x +11 = 4x -4x-24$ (Sum -4x on both sides of the equation)

$11 = -24$ The equation is not met, the x are eliminated, therefore, it has solution

For equation N°. 8

$-6x +3 = -6x + 5\\$

Solving algebraically:

$-6x + 6x +3 = -6x + 6x +5$ (Sum 6x on both sides of the equation)

$3 = 5$ The x are eliminated, 3 is not equal to 5, the equality is not met. The equation has no solution.

In parallelogram ABCD, find m∠A. A) 15° B) 70° C) 110° D) 200°

hram777 [196]

You might know this property of parallelogram that "Consecutive angles are supplementary" i.e A + D = 180. So 6x + 20 + 4x + 10 = 180. 10x = 150. x= 15. Therefore ∠A = 6x + 20 = 6( 15) + 20 = 110°. so option C is correct.
