Answer:

See below.

Step-by-step explanation:

Substitute the values for x.

h(-5) = 4(-5) - 5 = -25

h(-1) = 4(-1) - 5 = -9

h(2) = 4(2) - 5 = 3

h(3) = 4(3) - 5 = 7

h(5) = 4(5) - 5 = 15

Given that B is the midpoint of segment AC, find the unknown values.
shusha [124]
Hi! for x, you need to do 2x-8 = x+17 and solve, because since b is the midpoint, ab and bc would be congruent.

2x-8 = x+17
1x-8 = 17
1x = 25
x = 25

in order to find ab, you plug in the x into the expression.

ab = 2x-8
ab = 2(25)-8
ab = 42

do the same for bc:

bc = x + 17
bc = 25 + 17
bc = 42

and for ac, combine the two expressions and plug in the value for x.

ac = ab + bc
ac = 2x-8 + x+17
ac = 2(25)-8 + 25+17
ac = 84

i hope this helped! have a good day/night :)

How to find cp if loss and sp are given​
velikii [3]

Step-by-step explanation:

\tt{ \: H \: E \: Y \: \:  T \: H \: E \: R\: E \: } !

When Loss and Selling price ( SP ) are given , Cost price ( CP ) can be found out using the following formulae :

✰ \large{ \boxed{ \boxed{ \tt{CP = Loss + SP}}}}

\text{How \: did\: we \:get  \:the \: formula :  \: CP \:  = Loss \:  +  \: SP} \: ?

We simply derived the formula from Loss = CP - SP.

First , Swap the sides of the equation :

⟶ \text{CP - SP = Loss}

Move SP to right hand side and change it's sign :

⟶\text{CP = Loss + SP}

This is how , CP can be obtained when we are given loss and SP.

Hope I helped ! ♡

Have a wonderful day / night ! ツ

A poll was conducted to determine what percentage of the peoplesupport a certain candidate for the U.S. Senate.400 people were s
seropon [69]

Answer: 0.064

Step-by-step explanation:

The formula to find the margin of error :-

E=z_{\alpha/2}\sqrt{\dfrac{p(1-p)}{n}}

Given : Significance level : \alpha=1-0.99=0.01

Critical value : z_{\alpha/2}=2.576

Sample size : n=400

The proportion of people support the candidate :p=0.44

Then , E=(2.576)\sqrt{\dfrac{0.44(1-0.44)}{400}}\approx0.064

Hence, Margin of error = 0.064
