Answer:

(4x + 3) + (-2x + 4) = 2x + 7

Step-by-step explanation:

(4x + 3) + (-2x + 4) = you then collect like terms

(4x + -2x) + (3 + 4)= like this, and you add what's inside perenthesis

= 2x + (3 + 4). step-by-step

= 2x + 7. then that is how you get =2x+7

Find the estimates of x^2-x-2=3

Julli [10]

Answer:

$x=\frac{1+\sqrt{21}}{2}\approx 2.79\\or\ x=\frac{1-\sqrt{21}}{2}\approx -1.79$

Step-by-step explanation:

Given

Quadratic equation is

$x^2-x-2=3\\x^2-x-5=0$

Roots of the quadratic equation $ax^2+bx+c=0$ are

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\$

So, for the given equation roots are

$x=\frac{1\pm\sqrt{(-1)^2-4(1)(-5)}}{2\cdot 1}\\x=\frac{1\pm\sqrt{21}}{2}\\so, x=\frac{1+\sqrt{21}}{2}\approx 2.79\\or\ x=\frac{1-\sqrt{21}}{2}\approx -1.79$

Please help thanks!!

Minchanka [31]

-2|3x+2| = -12

|3x+2| = 6

3x + 2 = 6

3x + 4

x = 4/3

|3x+2| = -6

3x +2 = -6

3x = -8

x = -8/3

So we have the answers being 4/3 and -8/3

Write an equation in slope intercept form, passes through (-1,-10), parallel to y=7

gregori [183]

The line y=7 is a horizontal line with a slope of 0.
Slope intercept form of
y=mx+b

would be
y-y1=m(x-x1)
m=0 and point of (-1,-10)
y-(-10)=0

y=-10
