Answer:

x =  \frac{21}{4}  \\

Step-by-step explanation:

\frac{2x+3}{15}  =  \frac{9}{10}  \\  \\ (10)(2x + 3) = (9)(15) \\ 20x + 30 = 135 \\ 20x = 135 - 30 \\ 20x = 105 \\ x =  \frac{105}{20}  \\  \\ x =  \frac{21}{4}

What is the equation of this graph
Soloha48 [4]

Answer:

Step-by-step explanation:

hello :

an equation of this graph is : f(x) = a(x-h)²+k when (h,k) the vertex

so : h=5 and k= -4

f(x) = a(x-5)²-4....... now calculate : a

the y- intercept is :  - 6.5 means : f(0) = - 6.5

put x=0 and f(x) = - 6.5

you have : -6.5 = a(0-5)²-4

-6.5 = 25a - 4

25a = -2.5   so : a= -2.5/25= 1/10

the equation is :

<h2>f(x) = (1/10)(x-5)²-4</h2>

x = 6   (multiply both sides by 2)

Hope this helps.
