Please help me solve these are quadratic equations: I

julia-pushkina [17]

Answer:

$\boxed {\boxed {\sf a= 3, b=7, c=2}}$

$\boxed {\boxed {\sf Y-intercept = c }}$

$\boxed {\boxed {\sf Minimum}}$

Step-by-step explanation:

a. a, b, c

Quadratic equations in standard form are written as:

$f(x)= ax^2+bx+c$

The exponents are listed from greatest to least. The quadratic is already in this form, so match up the variables and values in the equation.

$f(x)= 3x^2+7x+2$

$a=3 \\b=7 \\c=2$

b. Y-intercept

The y-intercept for a quadratic is c.

You can also substitute 0 in for x, because the y-intercept occurs when the quadratic crosses the y-axis (at x=0).

$f(0)= 3(0)^2+7(0)+2$

$f(0)=3(0)+7(0)+2\\f(0)= 0+0+2\\f(0)=2$

We know that c=2, so the y-intercept is c.

c. Maximum/minimum

The entire quadratic is positive, so the quadratic opens up and has a minimum.

Which values of P and Q result in an equation with exactly one solution? Px -43= -42x+Q. Choose all answers that apply. A. P= 42

Vladimir79 [104]

Answer:

All are valid

Step-by-step explanation:

Px - 43 = -42x + Q (rearrange)

x = (Q+43) / (P + 42) <----Substitute options for P & Q into this equation to see which combination gives exactly 1 solution for x

A) P=42, Q = 42; x = (42+43) / (42+42) = 1.011 (only 1 solution = valid)

B) P=43, Q = -42; x = (-42+43) / (43+42) = 0.012 (only 1 solution = valid)

C) P=-43, Q = -43; x = (-43+43) / (-43+42) = 0 (only 1 solution = valid)

D) P=42, Q = 43; x = (42+43) / (42+42) = 1.023 (only 1 solution = valid)
