Please solve with elimination

Answer:

Step-by-step explanation:

5x+9y=-3 Multiply both sides by 8

40x+72y=-24

-53x-8y=-3 Multiply both sides by 9

-477x -72y= -27

sum the equations vertically to eliminate one variable

40x+72y= -24

-477x-72y= -27 (the y cancels out )

-477x =-51 (-24 + -27=-51)

-477x=-51 / -477 divide both sides by -477

x =51/437

5x 51/437=9y= -3 substitute the value of x

y= -174 /437

(x,y) = (51/437, -174/437)

Answer:

Inverse of the function does not exist.

Step-by-step explanation:

Inverse of a function: Inverse of a function $f(x)$ is a function that brings range to domain of $f(x)$ .

$f(x)=y\ inverse\ function\ is\ f^{-1}(y)=x$ .

Given $f(x)=|x|$

This function is not one-one map because $f(x)=f(-x)$

$f(2)=2,\ f(-2)=2 \Rightarrow f(2)=f(-2)$

Inverse function exists only if the function is one-one map.

Hence here inverse function does not exist.

Ms. Smith has a recipe for a batch of cookies that calls for ¼ cup of flour but she has to cut the recipe into a half because of

melomori [17]

Answer:

$\frac{1}{8}$ cup of flour

Step-by-step explanation:

To change the ÷ sign to a × sign, swap the denominators and numerators of the second fraction.

$\frac{1}{4}$ ÷ $\frac{2}{1}$ = $\frac{1}{4}$ × $\frac{1}{2}$

Directly multiply. (Denominators with denominators and numerators with numerators)

$\frac{1}{4}$ × $\frac{1}{2}$ = $\frac{1}{8}$
