What is the expression for f(x)f(x)f, (, x, )when we rewrite \dfrac{5^{-4x+7} }{ 125^{x}} 125 x 5 −4x+7 start fraction, 5, start superscript, minus, 4, x, plus, 7, end superscript, divided by, 125, start superscript, x, end superscript, end fraction as 5^{f(x)}5 f(x) 5, start superscript, f, (, x, ), end superscript ?

the answer is (-4,-4)

hope this ! : d

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct

b, 20 yards

step-by-step explanation:

answer: it actually depends on which is the independent variable and which is the dependent variable. let us say we're looking at a linear equation. y=2x+3. we theoretically could switch the equation to be x=(y-3)/2 and it would be the same line. so either a causes b or it can be that b causes a. so technically the answer is false
