4t+7-9=-6+6t please help

1 answer:

7 0

Simplify. Combine like terms.

7 - 9 = -2

4t - 2 = -6 + 6t

Isolate the t. Note the equal sign. Add 2 to both sides, and subtract 6t from both sides

4t (-6t) - 2 (+2) = -6 (+2) + 6t (-6t)

4t - 6t = -6 + 2

Simplify

-2t = - 4

Isolate the t, divide - 2 from both sides

-2t/-2 = -4/-2

t = -4/-2

t = 2

t = 2 is your answer

hope this helps

yolanda had 47 customers on saturday from 6pm to 7pm on monday from 5 pm to 6 pm she had 20 customers what is the amount of perc

rusak2 [61]

Yolanda had 47 customers on Saturday from 6 to 7 pm. Then on Monday she only had 20 customers from 5pm to 6pm. Question: Let’s find how much percentage rate did Yolanda’s customer’s decreased over time. Solution => Saturday = 47 customers. => Monday = 20 customer. Let’s start solcing => 47 – 20 = 27 There are 27 customer that were lost over time. => 27 / 47 = 0.57 * 100 = 57% Let’s try checking our answer: => 47 * .57 = 26.79 or round off to 27, since we rounded off also our percentage.

4) (Assume AR is tangent) Given: AR 12 SR - 7.7 Find: cs (Round to nearest tenth.)

andreev551 [17]

The length of CS is 11.0

Explanation:

Given that the length of the tangent AR is 12

The length of SR is 7.7

To find: The length of CS

The tangent secant theorem states that "if a tangent and a secant are drawn from an external point to a circle, then the square of the measure of the tangent is equal to the product of the measures of the secant’s external part and the entire secant."

Applying the tangent secant theorem, we have,

$AR^2=SR\times RC$

Rewriting the above equation, we get,

$AR^2=SR(SR+SC)$

Substituting the values, we get,

$12^2=7.7(7.7+CS)$

Simplifying, we have,

$144=59.29+7.7CS$

Subtracting both sides by 59.29, we get,

$84.71=7.7CS$

Dividing both sides by 7.7, we have,

$11.0013=CS$

Rounding off to the nearest tenth, we get,

$11.0=CS$

Thus, the length of CS is 11.0

HELP ASAP!!!! Does someone mind walking me through this. I really need help.

The minimum of this graph is the focus of the parabola. I'm not sure with the maximum though but I think it doesn't have a maximum because the y value of the parabola will extend infinitely upward.
