Since y already equals something, x + 1.75, we can put its equivalent x + 1.75 in its place in the other equation. 
See the image for the rest of the solution steps.

Tanner used two ribbons of equal length to wrap packages One ribbon is 4/8 yard. Which of the following is NOT a possible lengyf
Artyom0805 [142]
The first thing we must do in this case is to rewrite the length of the first tape.
 We have then:
 4/8 = 2/4 = 1/2 = 3/6 yard
 Therefore, since the tapes have the same length, the following measure is NOT possible:
 4/6 yard
 Answer:
 
A. 4/6 yard

What's the domain and range for (×+4)-1
Sonja [21]
\bf a^{-{ n}} \implies \cfrac{1}{a^{ n}}\qquad \qquad&#10;&#10;\cfrac{1}{a^{ n}}\implies a^{-{ n}}\\&#10;---------------\\&#10;thus\\&#10;(x+4)^{-1}\implies \cfrac{1}{x+4}&#10;\\\\&#10;
\bf if\qquad \cfrac{1}{0} \implies undefined

so.. what value of "x" makes x+4 to 0?

the domain will be, all real numbers, except that value

about the range, "y" will take, whateve "x" can provide.. in this case... I think is all real numbers, except 0, because, if you give a few big values to "x", the fraction will simply have a bigger and bigger denominator, making the fraction smaller and smaller, ever approaching 0, but never getting there
