Verizon [17]4 years ago

6 0

Answer:

The answer in linear equation is 1.

Step-by-step explanation:

First, we multiply the 2 inside of the brackets,

2(3x + 6) = 18

6x + 12 = 18

6x = 18 - 12

6x = 6

x = 6/6

x = 1.

What is the end behavior of the graph of f(x) = x5 – 8x4 + 16x3?

choli [55]

Answer:

left end of graph will goes down and right end will go up.

Step-by-step explanation:

Given : f(x) = $x^{5}$ – 8 $x^{5}$ + 16x³.

To find : What is the end behavior of the graph.

Solution : We have given that f(x) = $x^{5}$ – 8 $x^{5}$ + 16x³.

By the End behavior : If the degree is odd and leading coefficient is positive then left end of graph will goes down and right end will go up.

We can see f(x) = $x^{5}$ – 8 $x^{5}$ + 16x³ has degree 5 and leading coefficient = positive.

Therefore, left end of graph will goes down and right end will go up.

What does x equal? 2/7(x+4)=−6

SashulF [63]

Answer:

$\boxed{x=-25}$

Step-by-step explanation:

$\frac{2}{7} (x+4)=-6$

→ Multiply everything by 7 to get rid of the fraction

$2(x+4)=-42$

→ Expand the bracket

$2x+8=-42$

→ Minus 8 from both sides to isolate 2x

$2x=-50$

→ Divide both sides by 2 to isolate x

$x=-25$

The time to complete the construction of a soapbox derby car is normally distributed with a mean of three hours and a standard d

natta225 [31]

Answer:

Step-by-step explanation:

In this question, we will be calculating the probability between a range using normal distribution.

We proceed as follows;

we have, mean (μ)= 3 and standard deviation (σ) = 1

P(2.5<X<3.5) = P(2.5 - 3 < X- μm < 3.5 -3) = P( -0.5/1 < (X - μ ) /σ < 0.5/1 )

since Z= (X - μ ) / σ

P(2.5<X<3.5) = P(-0.5 < Z < 0.5)

Using Standard Normal Table or Z-calculator it can be found that ,

P(-0.5 < Z < 0.5) = 0.383

because P(−0.5<Z<0.5 ) = P ( Z<0.5 ) − P (Z<−0.5 )

using Standard Normal Table : P ( Z<0.5 )=0.6915 and P ( Z<−0.5 ) can be found by using the following fomula.

P ( Z<−a)=1−P ( Z<a )

After substituting a=0.5 we have: P ( Z<−0.5)=1−P ( Z<0.5 )

We see that P ( Z<0.5 )=0.6915 so,

P ( Z<−0.5)=1−P ( Z<0.5 )=1−0.6915=0.3085

At the end we have: P (−0.5<Z<0.5 )= P ( Z<0.5 ) − P (Z<−0.5 ) = 0.383
