Given AB= BC FINDIND X= AB= BC= AC=

Mathematics
1 answer:
tester [92]3 years ago
8 0

Answer:

see explanation

Step-by-step explanation:

Given AB ≅ BC, then

AB = BC = x + 6 , and

AC = AB + BC ← substitute values

3x - 31 = x + 6 + x + 6, that is

3x - 31 = 2x + 12 ( subtract 2x from both sides )

x - 31 = 12 ( add 31 to both sides )

x = 43

Hence

AB = BC = x + 6 = 43 + 6 = 49

AC = 3x - 31 =(3 × 43) - 31 = 129 - 31 = 98

Answer:

Range: (-∞, 0]

General Formulas and Concepts:

<u>Algebra I</u>

  • Range is the set of y-values that are outputted by function f(x)

Step-by-step explanation:

When we graph the equation, we should see that our y-values span from -∞ to 0. Since 0 is a closed dot, it is inclusive in the range:

(-∞, 0] or y ≤ 0

debra buys a new mountain bike for 750 dollars . Sales tax is 9% . how much does Debra actually have to pay ?
Georgia [21]

Answer:

$817.50

Step-by-step explanation:

Hello  Matt7151!

To find the total amount, we will first need to find how much tax.

We can express 9% as the fraction \frac{9}{100}.

\frac{9}{100} × 750 = 67.50

So she's paying $67.50 sales tax.

750.00

  67.50

-------------------

 817.50

So Debra's really paying $817.50.

Thus, the answer is \boxed{$817.50}$$\boxed{817.50}$.

Fill in the table using this function rule. <br><br> y=-2x+3<br><br> × -2, -1, 0, 1
ycow [4]

Answer:

If x = -2, -1, 0, 1, then (In this order) y = 7, 5, 3, 1

Step-by-step explanation:

If you put in each value of "x" into the equation, you'll get the appropriate "y".

y= -2(-2)+3

y= 4+3

y= 7

y= -2(-1)+3

y= 2+3

y= 5

y= -2(0)+3

y= 0+3

y= 3

y= -2(1)+3

y= -2+3

y= 1
