How would the number be written in standard form? 30,000+500+70+6

Write the equation of each line in slope-intercept form (just do the graph questions)

anyanavicka [17]

Step-by-step explanation:

x=2 y=0

x= -2 y= -4

y=mx+b

b= 2

-4 = -2m +2

-2m= -6

m=3

y= 3x +2

.......

x=0 y=4

x=2 y= 2

y=mx+b

b=4

2=2m+4

2m= -2

m= -1

y = -x +4

Factor using GCF and Area Model: 2x^2+34x+140 Factor using Area Model: x^2+4x-77

WITCHER [35]

Answer: Factoring using GCF 2x^2+34x+140-- 2(x+7)(x+10)

x^2+4x-77 --> (x-7)(x+11)

Step-by-step explanation: I don't know if these are 100 percent correct, since I'm learning these as well at the moment but I just wanted to help you out.

Find the equations of the tangents to y=x^2 which pass through the point (2,3).

algol [13]

Answer: The equations of the tangents that pass through

y = -x- 1 and

y = 11x -25

Step-by-step explanation: The gradient of the tangent to a curve at any particular point is given by the derivative of the curve at that point. So for our curve (the parabola) we have

y= x^2 +x

Differentiating wrt x we get:

dy/dx = 2x +1

Let P (a, B) be any generic point on the curve. Then the gradient of the tangent at P is given by:
