F(x) = x + 4
g(x) = 2x - 3
(g - f)(2) = (2x - 3) - (x + 4)
(g - f)(2) = (2x - x) + (-3 - 4)
(g - f)(2) = x - 7

F(x)= x+4
g(x)= 2x-3


(g-x)(x) = [2x-3] -[x+4]
= 2x-x-3-4
= x-7



(g-x)(2)= (2)-7
= -5

(0, 1) , (4, 2) equation in slope intercept form
mihalych1998 [28]

Answer:

2=1/4(4+b)

Step-by-step explanation:

(0,1), (4,2)

first, find the slope

slope formula- (y2-y1)/(x2-x1)

plug in the coordinates

(2-1)/(4-0)

subtract

1/4

slope=1/4

slope intercept form- y=mx+b

choose one of the coordinates to plug in

(4,2)

plug it in

2=1/4(4+b)

Complete the statement by typing the letter of the angle.<br> m∠ =54º
tekilochka [14]

Answer:

x = 16

∠A = 39

∠B = 54

∠C = 87

Step-by-step explanation:

Make a equation of all of the angles added together is equal to 180 since the angles of a triangle added together is 180

(4x-10)+(2x+7)+(7x-25)=180

combine like terms

4x+2x+7x-10+7-25 = 180

13x-28=180

solve for x

13x=208

x = 16

plug in x to find the measure of the angle

∠A = 2(16) + 7 = 39

∠B = 4(16) - 10 = 54

∠C = 7(16) - 25 = 87

Add them together to double check your answer

39 + 54 + 87 = 180

hope this helps

A lab is testing the amount of a certain active chemical compound in a particular drug that has been recently developed. The man
Mazyrski [523]

Answer:

The 95% confidence interval is "87.94, 91.86".

Step-by-step explanation:

The given values are:

Sample batches,

n = 25

Sample mean concentration,

\bar{x} = 89.9 mg

Amount of chemical,

σ = 5

α = 0.05

The critical value from Z table will be:

=  Z(\frac{\alpha}{2} )

=  Z(\frac{0.05}{2} )

=  1.96

Now,

The confidence interval will be:

=  \bar{x}  \pm Z(\frac{\alpha}{2} )\times \frac{\sigma}{\sqrt{n} }

On substituting the values, we get

=  89.9 \pm Z(\frac{0.05}{2})\times \frac{5}{\sqrt{25}}

=  89.9 \pm Z(\frac{0.05}{2})\times \frac{5}{5}

=  89.9 \pm1.96\times 1

Lower limit will be:

=  89.9 -1.96\times 1

=  87.94

Upper limit will be:

=  89.9 +1.96\times 1

=  91.86
