Answer:

(A)

Step-by-step explanation:

A linear equation can be written in slope intercept form, y=mx+b.

X must be in it's first power in a linear equation. X being in any other power will result in a curved line.

This eliminates B, C and D already. X is not in it's first power in the given three options.

The best option is A.

Explain how the graph of y=|x+1|-2 will differ from the graph of y=|x|.
Natali5045456 [20]

\bf ~~~~~~~~~~~~\textit{function transformations}\\\\\\f(x)=  A(  Bx+  C)+  D\\\\~~~~y=  A(  Bx+  C)+  D\\\\f(x)=  A\sqrt{  Bx+  C}+  D\\\\f(x)=  A(\mathbb{R})^{  Bx+  C}+  D\\\\f(x)=  A sin\left( B x+  C  \right)+  D\\\\--------------------\\\\\bullet \textit{ stretches or shrinks horizontally by  }   A\cdot   B\\\\\bullet \textit{ flips it upside-down if }  A\textit{ is negative}

\bf ~~~~~~\textit{reflection over the x-axis}\\\\\bullet \textit{ flips it sideways if }  B\textit{ is negative}\\~~~~~~\textit{reflection over the y-axis}\\\\\bullet \textit{ horizontal shift by }\frac{  C}{  B}\\~~~~~~if\ \frac{  C}{  B}\textit{ is negative, to the right}

\bf ~~~~~~if\ \frac{  C}{  B}\textit{ is positive, to the left}\\\\\bullet \textit{ vertical shift by }  D\\~~~~~~if\   D\textit{ is negative, downwards}\\\\~~~~~~if\   D\textit{ is positive, upwards}\\\\\bullet \textit{ period of }\frac{2\pi }{  B}

with that template in mind,

\bf y=\stackrel{A}{1}|\stackrel{B}{1}x\stackrel{C}{+1}|\stackrel{D}{-2}

so is really just |x| but shifted some,

C/B = 1/1 = +1, horizontally to the right by 1 unit.

D = -2, vertically downwards by 2 units.

Simplify the expression.
OlgaM077 [116]

Answer:

5.1

Step-by-step explanation:

-44.288-31.6 / -3.1(6-1.2)

Add -44.288 and -31.6

= -75.888 / -3.1(6-1.2)

Subtract 1.2 from 6

= -75.888 / -3.1(4.8)

Multiply -3.1 and 4.8

= -75.888 / -14.88

Divide -75.888 by -14.88

-75.888 / -14.88

=5.1
