Answer:

\displaystyle f(x)=-\frac{1}{2}(x+1)^2+6

Step-by-step explanation:

We want to write the equation for a quadratic function in vertex form with vertex at (-1, 6) that passes through the point (-3, 4).

Vertex form is given by:

\displaystyle f(x)=a(x-h)^2+k

Where (<em>h, k</em>) is the vertex and <em>a</em> is the leading coefficient.

Since our vertex is at (-1, 6), <em>h</em> = -1 and <em>k</em> = 6. Substitute:

f(x)=a(x-(-1))^2+(6)

Simplify:

f(x)=a(x+1)^2+6

Next, since the quadratic passes through the point (-3, 4), f(x) = 4 when <em>x</em> = -3. Substitute:

(4)=a(-3+1)^2+6

Solve for <em>a</em>. Simplify:

-2=a(-2)^2

Hence:

\displaystyle -2=4a\Rightarrow a=-\frac{1}{2}

Therefore, our function in vertex form is:

\displaystyle f(x)=-\frac{1}{2}(x+1)^2+6

I don’t know the depth but I can tell you that you need to multiply everything using the formula v=l*w*h. So v=3.5*0.5*x

Determine if (3, 7) is a Solution or not Solution to the linear system.
spayn [35]

Answer:

y = 2x + 1 --> linear

y = -4x + 7 --> non-linear

Not a solution for linear system.

Step-by-step explanation:

for (a), y = 2x+1, substitute the x and y values. keep in mind, that in a linear pair, (x, y). So, for the first equation you get:

7 = 2x3 + 1. This is correct, because 6 + 1 is 7. Therefore, (a) is linear.

for (b), we have to substitute our values again. You get:

7 = -4x3 + 7, which is

7 = -12+7, which is not true. So, (b) is not linear.

This means that for the linear pair (3, 7), it does not satisfy both equations, which means that it is not a solution for the linear system.
