Find the values of a and b such that x^2 + 3x + 4 = (x + a)^2+ b

sesenic [268]

Answer:

$x {}^{2} + 3x + 4 = (x + a) {}^{2} + b \\ x {}^{2} + 3x + 4 = x {}^{2} + 2ax + a {}^{2} + b \\ = x {}^{2} + a {}^{2} + 2ax + b \\ 2a = 3 \\ b = 4 \\ a = \frac{3}{2} \\ b = 4$

Question 21

horsena [70]

Answer:

A(x) = 6x² + 26x

Step-by-step explanation:

A(x) = 4x ( x + 10 ) - 2x ( 8 ) + $\frac{2x(x)}{2}$ + $\frac{2x(x+2)}{2}$

A(x) = 4x² + x² + x² + 40x - 16x + 2x

A(x) = 6x² + 26x

What is the slope of the line x + 6y= 12

Lubov Fominskaja [6]

x + 6y = 12

You want the y-value to be on one side of the equation, so you have to subtract the x-value from both sides.

6y = -x + 12

Next, you divide both sides by 6, so that the y-value will be by itself.

y = - $\frac{1}{6}$ + 2

We know that the slope or the 'm' value is located before the x-value based on y = mx +b, therefore the slope is - $\frac{1}{6}$
