Determine the intercepts of the line.

iogann1982 [59]

Answer:

y-intercept: (0,5)

x-intercept: (5/2,0)

Step-by-step explanation:

$-4x+7=2y-3$

$-4(0)+7=2y-3$

$0+7=2y-3$

$7=2y-3$

$10=2y$

$5=y$ <-- y-intercept: (0,5)

$-4x+7=2y-3$

$-4x+7=2(0)-3$

$-4x+7=-3$

$-4x=-10$

$x=\frac{5}{2}$ <-- x-intercept: (5/2,0)

What is (-7)^3 / (-7)^4 simplified? Can you walk me through the steps?

Brilliant_brown [7]

Answer:

(-7)∧-1

Step-by-step explanation:

(-7)^3 / (-7)^4

taking each and simplifing it

-7³ = -7 x -7 x -7

(-7)∧4 = -7 x -7 x -7 x -7

(-7)^3 / (-7)^4 = (-7 x -7 x -7 ) / ( -7 x -7 x -7 x -7) = 1/-7

1/-7 ( 1/ means raise to power -1)

1/-7 = (-7)∧-1

Tanisha solved the equation below by graphing a system of equations. log3 5x = log5 ( 2x + 8). What system of equations could be

Marta_Voda [28]

Answer:

The set

$y=log_3 (5x)$

$y=log_5 (2x+3)$

Step-by-step explanation:

We separate the left and right side of the equation, to create two new equations:

(1) $y=log_3 (5x)$

(2). $y=log_5 (2x+3)$

and then to solve Tanisha's original equation, we find the solution to the system that we got above.

The first step in solving the above system of equations is to take the value for $y$ from equation(1), and substitute it into equation(2) which gives us:

$y=log_5 (2x+3)\\\\ \boxed{log_3(5x) = log_5 (2x+3)}$

which is the same equation that Tanisha set out to solve.
