Answer:

-5z - 2

Step-by-step explanation:

x - yz when x = -2 and y = 5

-2 - 5z

Since we don't have any like terms and an equal sign, we can't simplify any further.

Best of Luck!

Log8 (t) - log8 (5) = 1

djyliett [7]

Answer:

t = 40

Step-by-step explanation:

Given the logarithmic expression: $log_8 (t) - log_8 5= 1$

Use the Logarithmic Property (Quotient Rule):

$log_b a - log_b c = log_b (\frac{a}{c})$

$log_8 (t) - log_8 5 = log_8 (\frac{t}{5}) = 1$

Next, using the Logarithmic Property: $log_b b= 1$

We must determine the possible value of t that can be divided by 5 to produce a quotient of 8 that will make the logarithmic property, $log_b b= 1$ , true. In that case, t = 40 divided by 5 results in a quotient of 8.

$log_8 (t) - log_8 5 = log_8 (\frac{t}{5}) = log_8 (\frac{40}{5}) = log_8 8 = 1$

Therefore, the value of t = 40.

Question 1 (1 point)

Natalija [7]

Answer: OPTION B.

Step-by-step explanation:

Given the equation $48=-8(\frac{3b}{4}+2)$ you can find an equivalent equation by simplifying it.

You need to remember the multiplication of signs:

$(-)(-)=+\\(+)(+)=+\\(+)(-)=-$

Now you can apply the Distributive property:

$48=\frac{(-8)(3b)}{4}+(-8)(2)\\\\48=\frac{-24b}{4}-16$

Simplifying the equation, you get:

$48=-6b-16$

You can observe that this equivalent equation matches with the equation provided in option B.
