What is the vertex of this equation Y-7=-1/16(x-10)^2
VLD [36.1K]
The formula for a vertex form equation is
y = a(x - h) + k
in which (h,k) represents the vertex

Your equation is in vertex form, if you mpve the -7 to the other side you will get
y =  -  \frac{1}{16} (x - 10) ^{2}  + 7
because you have to add 7 to both sides

based on the equation,
h=10
k=7
(h,k)=(10,7)

your vertex is (10,7)

Someone plzzzz helppppppp idkk wat to do
Oksi-84 [34.3K]

Answer:

9x/4= -9

Mutiply by 4 for both sides.

4(9x/4) cross out 4 and 4, divide by 4 and then becomes 9x. (-9)(4)= -36

9x= -36

Divide by 9 for both sides

9x/9= -36/9

x= -4

The points (0,4) and (1, 9) fall on a particular line. What is its equation in slope-intercept
Vitek1552 [10]

Answer:

The equation is y = 5x + 4.

--

Step-by-step explanation:

☆Remember: m =  \frac{y_2 - y_1}{x_2 - x_1}

☆Slope-intercept: y = mx + b

---

☆We need to find the slope first. So just plug in according to the slope formula!

m =  \frac{9 - 4}{1 - 0}  =  \frac{5}{1}  = 5

---

☆Now we need to find the y-intercept. We are going to plug in the slope and a set of coordinates to find the y-intercept.

y = mx + b \\ 9 = 5(1) + b \\ 9 = 5 + b \\  \frac{ - 5 =  - 5 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: }{4 = b \:  \:  \:  \:  \:  \:  \:  \:  \: }

---

☆Now all we need to do is plug in and we are done!

y = 5x + 4
