Answer:x<-7

Step-by-step explanation:

3x -15x - 30 > 54

-12x-30>54

-12x<54+30    

I moved 30 from left side to right which becomes positive and > becomes <

Write an exponential function in the form y=ab^x that goes through points (0, 17) and (2,153).
garik1379 [7]

Answer:

y = 17*(3)ˣ

Step-by-step explanation:

y=abˣ

(0,17) : 17 = a*b⁰ = a

(2,153) : 153 = a*b² = 17*b²

b² = 153/17 = 9

b = ± 3  ... (0,17) and (2,153) in first quadrant   b = 3

function: y = 17*(3)ˣ

HELP ASAPPPPPPP!!!!!!!!!!!
kolbaska11 [484]

Answer:

x = 15

Step-by-step explanation:

you have a straight line and a straight line measures 180.  You have a 90 degree symbol.

180 = 90 + 47 + 2x + 13

180 = 150 + 2x  Subtract 150 from both sides of the equation

30 = 2x  Divide both sides by 2

15 = x

All you need is in the photo I DON'T WANT STEP BY STEP ANSWER FAST please fdsd
Brut [27]

We have the following:

\begin{gathered} x=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a} \\ a=5 \\ b=0 \\ c=-80 \end{gathered}

replacing:

\begin{gathered} x=\frac{-0\pm\sqrt[]{0^2-4\cdot5\cdot-80}}{2\cdot5}=\frac{\pm\sqrt[]{1600}}{10}=\frac{\pm40}{10}=\pm4 \\ x_1=4 \\ x_2=-4 \end{gathered}
