we know that

The equation of a vertical parabola in vertex form is equal to

y=a(x-h)^{2}+k

where

(h,k) is the vertex

if a > 0 -----> then the parabola open upward (the vertex is a minimum)

if a < 0 -----> then the parabola open downward (the vertex is a maximum)

The axis of symmetry is equal to

x=h

In this problem let's analyze two cases

First case

f(x)=3(x-2)^{2}+4

the vertex is the point (2,4)

a=3

so

3 > 0 -----> then the parabola open upward (the vertex is a minimum)

The axis of symmetry is equal to

x=2

Second case

f(x)=3(x-2)^{2}-4

the vertex is the point (2,-4)

a=3

so

3 > 0 -----> then the parabola open upward (the vertex is a minimum)

The axis of symmetry is equal to

x=2

Lines s and t are perpendicular if the slope of line s is 5 what is the slope of line t
ycow [4]

The slope of line T is -1/5, because perpendicular lines have opposite reciprocal slopes, meaning the opposite sign (positive or negative) and flipped (whole number becomes a fraction).

Slope 8 ​; through ​(4​,3​)
Reptile [31]

Answer:

y=8x-29

Step-by-step explanation:

Since we know the slope (m) is 8, we can plug it in the slope-intercept formula y=mx+b, making y=8x+b.

Now we need to find the y-intercept (b). To do that, you would need to plug in the points given to you, which were (4,3).

x=4, y=3... so 3=8(4)+b

Now you can solve for the variable b to find the y-intercept.

3=8(4)+b, multiply...

3=32+b, subtract 32 on both sides...

-29=b

Therefore, the y-intercept, or b, is -29.

The equation would be y=8x-29
