Compare and Contrast: Below are two equations. Solve each equation and compare the two solutions. Choose the statement that is t

grin007 [14]

Equation #1:
|2x - 3| = 17
The first solution is
2x - 3 = 17
2x = 17 + 3 = 20
x = 10
The second solution is
3 - 2x = 17
-2x = 17 - 3 = 14
x = -7
The solutions are x = 10 or x = -7.

Equation #2:
|5x + 3| = 12
The only solution is
5x + 3 = 12
5x = 12 - 3 = 9
x = 9/5

Let us examine the given answers.
a. Equation #1 and #2 have the same number of solutions.
FALSE
b. Equation @1 has more solutions than Equation #2.
TRUE
c. Equation #1 has fewer solutions than equation #2.
FALSE
d. None of the statements a,b, or c apply.
FALSE

Answer: b.

I need help fast geometry is impossible

Ierofanga [76]

Answer:

D. 8

Step-by-step explanation:

DC = AC = x is the radius

<u>Using the Pythagorean theorem, find x:</u>

(x + 9)² - x² = 15²
x² + 18x + 81 - x² = 225
18x = 225 - 81
18x = 144
x = 144/18
x = 8

I need help finding the lowest term for -8/9+11/15

Liono4ka [1.6K]

Answer:

-7/45

Step-by-step explanation:

First, find the lowest common denominator for 9 and 15. It's 45. Make both fractions over 45 by multiplying the top and bottom by the same number.

$-\frac{8}{9} +\frac{11}{15}$

$= -\frac{8*5}{9*5} +\frac{11*3}{15*3}$ Since 15*3=45, multiply the top by 3 also. Since 9*5=45, multiply the top by 5 also.

$= -\frac{40}{45} +\frac{33}{45}$

$= \frac{-40+33}{45}$ Combine the fractions

$= -\frac{7}{45}$ Answer in lowest terms

natalie guessed on the last four true or false questions on her math quiz. what is the probability that she got all four quiz qu

Verizon [17]

Each question is either true or false, so the sample space is 2, true and false, two states only.

what's the probability she got one correct, well, the favorable outcomes is 1, possible outcomes is 2, so 1/2.

what's the probability that she got all four correct, we simply multiply the probability of each,

$\bf \cfrac{1}{2}\cdot \cfrac{1}{2}\cdot \cfrac{1}{2}\cdot \cfrac{1}{2}\implies \cfrac{1}{16}\implies 0.0625\qquad or\qquad 6.25\%$
