3x-x-5=2(x+2) -9<br> please help

irga5000 [103]

Answer:

infinite solutions

Step-by-step explanation:

Simplify 3x-x-53x−x−5 to 2x-52x−5.

2x-5=2(x+2)-92x−5=2(x+2)−9

2 Expand.

2x-5=2x+4-92x−5=2x+4−9

3 Simplify 2x+4-92x+4−9 to 2x-52x−5.

2x-5=2x-52x−5=2x−5

4 Since both sides equal, there are infinitely many solutions.

Solving Exponential and Logarithmic Equation In exercise,solve for x or t.See example 5 and 6.

Aloiza [94]

Answer:

0.70275

Step-by-step explanation:

Data provided in the question:

4e²ˣ⁻¹ -1 = 5

now solving for 'x'

⇒ 4e²ˣ⁻¹ = 5 + 1

⇒ 4e²ˣ⁻¹ = 6

⇒ $e^{(2x-1)} =\frac{6}{4}$

⇒ $e^{(2x-1)} =\frac{3}{2}$

now,

taking natural log both sides, we get

⇒ 2x - 1 = $\ln(\frac{3}{2})$

also,

we know

⇒ $\log(\frac{A}{B}) = \log(A)+\log(B)$

thus,

⇒ 2x - 1 = ln(3) - ln(2)

⇒ 2x - 1 = 1.0986 - 0.6931

⇒ 2x - 1 = 0.4055

⇒ 2x = 0.4055 + 1

⇒ 2x = 1.4055

⇒ x = 0.70275

A box of granola bars contains 3 chocolate chip bars, 2 peanut butter bars, 1 lemon bar, and 4 raisin bars. Iesha will randomly

ella [17]

Answer:

2/45

Step-by-step explanation:

Note this selection is done without replacement hence after each selection sample size will reduce

Given data

Samples 3 chocolate chip bars,

2 peanut butter bars,

1 lemon bar, and

4 raisin bars

Sample size S= [3+2+1+4]= 10

Probability that first selection is lemon = 1/10

Probability that second selection is raisin = 4/9

Hence the probability that the first bar Iesha selects will be lemon and the second will be raisin= 1/10*4/9

= 4/90= 2/45

PLEASE ANSWER + BRAINLIEST!!!

ozzi

Answer:

C is correct

Step-by-step explanation:

Given: System of linear inequality

$y$

$y\geq 2x+3$

First we will draw the graph of system of equation and then see the correct option.

Equation 1: $y$

We will make the table.

x : -2 0 2

y : 1 0 -1

Test Point: (0,4)

0<-2 ( False )

Shaded area away from (0,4)

Equation 2: $y\geq 2x+3$

We will make the table.

x : -2 0 2

y : -1 3 7

Test Point: (0,4)

4≥3 ( True )

Shaded area towards (0,4)

Please see attachment for graph.

Hence, C is common shaded area (region)
