Answer: f=125

Step-by-step explanation:

f=2\left(-7\right)^2-3\left(-7\right)+6

f=2\left(-7\right)^2+3\cdot \:7+6

f=7^2\cdot \:2+3\cdot \:7+6

f=7^2\cdot \:2+3\cdot \:7+6

f=98+27

f=125

Answer:

f(-7) = \bold{125}

Step-by-step explanation:

Given:

f(x) = 2x^2 - 3x + 6

f(-7) = 2(-7)^2 -3(-7) +6 \\ f(-7) = 2(49) -3(-7) +6 \\ f(-7) = 98 +21 +6 \\ f(-7) = 125

Identify the point. y + 2 = 4/3(x - 7)
MA_775_DIABLO [31]
The point-slope form of a line is:

y-y1=m(x-x1), where m is the slope of the line and (x1,y1) is any point on the line.

In this case x1=7 and y1=-2 so the point used to create this equation is:

(7, -2)

State the rule that will result in the transformation below.<br> (x,y) maps to (?, ?)
Anna [14]

Answer:

(x,y) maps to (-y,x).

Step-by-step explanation:

Use vertex I as an example.

Pre-image I is graphed at point (-3,2), while image I' is graphed at point (-2,-3) .

In order to change between these points, the x and y coordinates must be swapped, as well as multiplying the y coordinate by -1.

What are the effects of different operations on rational and irrational numbers?
lara31 [8.8K]

Answer:

An irrational number is a number that is not rational that means it is a number that cannot be written in the form  

p

q

. An irrational Number is a number on the Real number line that cannot be written as the ratio of two integers. They cannot be expressed as terminating or repeating decimals. For example.

Pi = 3.14…..It continues forever and never repeats. The few digits of  this pattern look like 3.1415926535897932384626433832795

√3 = 1.732050807. So one of the most important thing about irrational numbers is that it never repeats and never terminates.
