Answer:

x = 2

Step-by-step explanation:

Here's your solution

=> we know that tangents from a point to a common circle are equal

=> so, ST = SU

=> 7x - 3 = 5x + 1

=> 7x - 5x = 1 + 3

=> 2x = 4

=> x = 4/2

=> x = 2

hope it helps

. Dillion deposits $150 into his account. One week later, he withdraws $26. Write an addition expression to represent this situa

Lina20 [59]

Answer:

$Expression = x + 150 +(- 26)$

$124 higher

Step-by-step explanation:

Given

$Deposit = \$150$

$Withdrawal = \$26$

Required

Represent the situation

Determine how much higher or lower is the remaining amount

Let the initial amount in his account be represented with x

When he deposited, the balance becomes

$Balance = x + 150$

When he withdrew, the balance becomes

$Balance = x + 150 + (-26)$

Hence, the algebraic expression is

$Expression = x + 150 +(- 26)$

Calculating how much higher or lower

$Balance = x + 150 + (-26)$

Open bracket

$Balance = x + 150 -26$

$Balance = x + 124$

Recall that the initial amount in the account is x

The difference between the balance and the x is as follows

$Difference = x + 124 - x$

$Difference = \$124$

Hence, the account has a higher of $124 after both transactions

Find the cardinality of the set B = { 5, 6, 7, … , 100}

vaieri [72.5K]

The cardinality of the set B is given to be 96.

<h3>What is the cardinality of a set?</h3>

This is the term that is used to refer to the number of elements that a given set can be said to contain.

This is a set that has numbers that ranges from 5 to 100, this tells us that the numbers 1, 2, 3, 4 are excluded from the set.

Hence the total numbers excluded is 4. 100 - 4 = 96

Therefore from 5 to 100, the total 9 and the cardinality of the set B is 96.

What is the slope of the line that passes through the points (-2, -1) and (2, -3)?

Lady bird [3.3K]

Answer:

$m=\frac{-1}{2}$

Step-by-step explanation:

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Simply plug in the 2 coordinates into the slope formula to find slope m:

$m=\frac{-3-(-1)}{2-(-2)}$

$m=\frac{-3+1}{2+2}$

$m=\frac{-2}{4}$

$m=\frac{-1}{2}$
