2x + 3 = 4x^2 completing the square

ch4aika [34]

Answer:

$\frac{1+\sqrt{13} }{4}, \frac{1-\sqrt{13} }{4}$

Step-by-step explanation:

First, make them on one side of the formula in the form of $ax^2+bx+c=0$ which is $4x^{2} -2x-3=0$

Next, insert the corresponding number in the quadratic formula, $\frac{-b+\sqrt{b^{2}-4ac } }{2a} ,\frac{-b-\sqrt{b^{2}-4ac } }{2a}$ , and the answer can be calculated.

Lynda cuts a piece of wood for a project. The first cut is shown and can be represented by the equation y=1/4x-5.The secend cut

Svetradugi [14.3K]

Since the second line is parallel to the first, it will have the same slope. The y-intercept of the new line is 4 (because of the coordinates given) so the equation of Lynda's second cut is y = 1/4x + 4 which is choice C

Y=4x+3 table of ordered pairs

lara31 [8.8K]

Answer:

X:1 2 3 4 5 Y:7 11 15 19 23.

Step-by-step explanation:

We just need to put in the values of x into the equation: y = 4x + 3.

x = 1:

y = 4(1) + 3

= 4 + 3

y = 7

x = 2:

y = 4(2) + 3

= 8 + 3

y = 11

x = 3:

y = 4(3) + 3

= 12 + 3

y = 15

x = 4:

y = 4(4) + 3

= 16 + 3

y = 19

x = 5:

y = 4(5) + 3

= 20 + 3

y = 23

PLEASE HELPP ANYONE

$\frac{1}{2}(4x-2)(2x+12)=(2x-1)(2x+12)=4x^2+24x-2x-12= \\ =\boxed{4x^2+22x-12} \ \ cm^2$
