Answers

Answer:

3, -3, -1/2

Step-by-step explanation:

There is no need to distribute, just set each parenthesis to equal to zero.

p(x)= (x-3)(x+3)(2x+1)

X-3=0 x+3=0 2X+1=0

+3 +3 -3 -3 -1 -1

X=3 X=-3 2x=-1

x=-1/2

Write the equation of a line in slope intercept form given;
(6,-3), (0, 5)

Answers

Answer:

[tex]y=(-4/3)x+5[/tex]

Step-by-step explanation:

so you want to start by using y=mx+b

step one: find the slope (remember m is the slope in this)

m= [tex]\frac{y2-y1}{x2-x1}[/tex]

m= [tex]\frac{5+3}{0-6}[/tex]

m= [tex]\frac{8}{-6}[/tex]

m= - [tex]\frac{4}{3\\}[/tex]

step two: insert the value we found for m into the equation and take one of the given points and insert the x and y into the equation (im using (0,5)) and solve for b.

y=mx+b

5= -4/3(0)+b

5=b

step three: rewrite y=mx+b with the values we found for m and for b

[tex]y=(-4/3)x+5[/tex]

The ratio of the sides of a triangle is 2:4:9. If the perimeter is 165 inches, what is the length of the longest side?

Answers

Answer:

99inches

Step-by-step explanation:

The ratio of the sides of a triangle =2:4:9.

perimeter = 165 inches,

Total ratio= 2+4+9=15

perimeter = 165

Divide the perimeter by total ratio

165/15=11

Each of the sides

= (2×11) =22

(4×11) =44

(9×11)=99

the length of the longest side= 99inches

Write a linear function f with the values f(3)=2 and f(0)=6

Answers

Answer:

for f(3)=2 is y=(2/3)x

Step-by-step explanation:

y=ax

and plug x and y into the parent function.

Answer:

f(x) = -⁴/₃x + 6

Step-by-step explanation:

f(0) = 6 means y-intercept b = 6

So we have:

f(x) = mx + 6 and f(3) = 2

So:

2 = m×3 + 6

3m + 6 = 2

3m = 2 - 6

3m = -4

m = -⁴/₃

Therefore the function:

f(x) = -⁴/₃x + 6

P(red) = (0.35)(0.6) + (0.45)(0.2) + (0.20)(0.7) = 0.21 + 0.09 + 0.14 = 0.44

A prediction based on the data is not completely reliable, because the means are too close together. D. A prediction based on the data is reliable, because the means of the samples are close together.

Answers

Answer:

Step-by-step explanation:

The statement which is most accurate based on the data is option(D)A prediction based on the data is reliable, because the means of the samples are close together.

What is Mean?

Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers

From the given data,

Mean of the sample 1 = 15.9

Mean of the sample 2 = 15.7

Mean of the sample 3 = 15.6

All three mean are close together.

Therefore the data is reliable

Hence, the statement which is most accurate based on the data is option(D)A prediction based on the data is reliable, because the means of the samples are close together.
