Answer 1

Answer:

Factored Form: f(x) = (x-7)(x-4)

Roots: x=7, x=4

Step-by-step explanation:

What  we can do here is break the given expression into groups;

x^2-11x+28 ---> break the expression into groups

(x^2-4x) +(-7x+ 28) ---> factor out x from x^2-4x

x(x-4) + (-7x +28) ---> factor - 7 from -7x +28

x(x-4) -7(x-4) ---> combine

(x-7)(x-4)

so if f(x) = (x-7)(x-4) then the roots would be x=7 and x=4

Answers

Answer:

y = -1/2x + 7

Step-by-step explanation:

The slope is -1/2.

The y intercept is 7.

Plugging them into the format for the equation we have:

y = mx + b

(m = slope and b = y intercept)

y = -1/2x + 7

The area of the triangle P’Q’R’ is 384 square units

The formula for calculating the area of a triangle is expressed as:

A = 0.5bhb is the base of the triangleh is the height of the triangle.

If the right triangle PQR has sides of length 6 units, 8 units, and 10 units is dilated by a scale factor of 4 units, hence:

base = 4(6) = 24 unitsheight = 4(8) = 32 units

Area of the triangle P’Q’R’ = 0.5(24)(32)

Area of the triangle P’Q’R’ = 384 square units

Hence the area of the triangle P’Q’R’ is 384 square units

How would I solve this? I tried and I got a reallly crazy number... I think I messed up somewhere. The question is... Jack and Mark work together on a job, but not equal hours. Mark gets paid $11 per hour and Jack gets paid $10 per hour. Together they worked 58 hours and earn a total of $601. How many hours did each one work?

I made these equations.
m+j=58
11m+10j
The first one I rearranged to m=58-j.

Answers

37 x 10 = 370
21 x 11 = 231

Mark worked 21 Hours, Jack worked 37 Hours.

Answer:

Jack earns $37

Mark earns $21

Step-by-step explanation:

m + j = 58

11m + 10j = 601

j = 58 - m

11m + 10(58 - m) = 601

11m + 580 - 10m = 601

1m = 601 - 580

m = 21

j = 58 - m

j = 58 - 21

j = 37

Tom and Ana are both
botanists studying
flower pollination. In Tom's garden, the
ratio of roses to tulips is 3 : 1. In Ana's
garden, the ratio of roses to tulips is 5 : 2.
0 Part A: Tom's garden and Ana's garden
each have 30 tulips. H&w many more
roses are in Tom's garden than in Ana's
garden? Explain your reasoning.
Part B: Tom and Ana combined their
flowers into a single garden. What is the
ratio of roses to tulips in the combined
garden?

Answers

Answer:

A: tom has 15 more roses than ana does.

B: 11:4

Step-by-step explanation:

A: there is a 3:1 and 5:2 ratio of roses to tulips. that means that in tom's, there are 3 roses for every tulip and 5 roses for every 2 tulips in ana's.

we know that they each have 30 tulips so now for Tom.

3:1 so to find roses, we need to multiply the value of tulips to 3.

3×30=90 so we know he has a total of 90 roses.

for ana: she also has 30 tulips. BUT now her ratio is 5:2. so for every 2 tulips she has 5 roses. we need to divide the value of tulips by 2 so 30/2=15 and multiply it by 5, 15*5=75

THAT IS NOT THE ANSWER!! to find the rest of the answer, we have to subtract tom's amount by ana's amount: 90-75=15

B: to find this answer, we have to add all of the roses together and all of the tulips together. roses: 90+75=165. tulips: 30+30=60.

the ratio we get is 165:60. and now we need to simplify it.

x-intercept means the advertising expense when the company's profit was zero dollars ⇒ D

Step-by-step explanation:

Let us solve the question

∵ P = -250x³ + 1,505x² - 300, for 0 < x < 6

∵ P is the profit in tens of thousands of dollars

∵ x is the advertising expense in tens of thousands of dollars  

∴ x is the independent variable

∴ P is the dependent variable

→ x-intercept means value x when P is 0

∵ The x-intercept is the value x at P = 0

∴ x-intercept means the advertising expense when the company's

   profit was zero dollars
