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:

C

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.

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
lesya [120]

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.<br> A) 15° <br> B) 70° <br> C) 110° <br> D) 200°
hram777 [196]
 You might know this property of parallelogram that "<span>Consecutive angles are supplementary" i.e A + D = 180. So 6x + 20 + 4x + 10 = 180. 10x = 150. x= 15. Therefore </span>∠A = 6x + 20 = 6( 15) + 20 = 110°. so option C is correct.
