What are the zeros of the function?
f(x) = x2 - 4x – 5

What Are The Zeros Of The Function?f(x) = X2 - 4x 5

Answers

Answer 1
its the second one. x=-1 and x=5
If you factor x^2-4x-5 you get (x+1)(x-5) because you’re looking for something that multiplies to give you 5 (c) and something that adds to give you -4 (b). in this case that would be 1 and -5. then you set both (x+1) and (x-5) equal to zero and solve. this gives you your x intercepts/zeros. -1 and 5
Answer 2

Answer:

Its x = 5, x = -1

or B to be more precise

Is value of X in the equation 6x+3+4x= 1/2(9+10x)

Answers

Answer:

x = 0.3

Step-by-step explanation:

6x + 3 + 4x = 1/2 (9 + 10x)

=> 10x + 3 = 1/2 *9 + 5x

=> 5x + 3 = 9 / 2

=> 5x = 9 / 2 -3

=> 5x = (9 - 6) / 2

=> 5x = 3 / 2

=> x = 3 / 10

=> x = 0.3

Lucy, Luke, and Lilly went trick-or-treating on Halloween. After they finished, they compared the amount of candy they all had. Luke had twice the amount Lilly had, and Lucy had 15 less than 3 times the amount Lilly had. If together, they had 225 candies, how many candies did Lucy have? PLEASE HELP URGENT

Answers

Hi there!

Let think talk about these clues we have right now...

Luke is x2 more than Lily.

Luce is 45 less candy than Lily since 3 times 15.

225 candys in total...

Let make a random guess...

Lily: 70

Luke: 140

Lucy: 35

Total: 245

Now we know that there must be a half candy since it’s a odd number at the end of that...

Lily: 67.5

Luke: 135

Lucy: 22.5

Total: 225

But we are asked for only Lucy...

So the answer to this problem is 22.5.

Real life = scale drawing

If length = 6 meter long ;

using cross multiplication :

2 meter = 1 meter

6 meter = x

2x = 6

x = 6/2

A farmer sells a dozen eggs at the market for 2.00 and one of his bags of gains for 5.00 he sold 5 time as many bags of grains as he has dozens of eggs. By the end of the day he has made 243.00 worth of sales. How many bags of grain did he sell

Answers

Answer:

45 bags

Step-by-step explanation:

Cost of a dozen eggs = 2

A bag of grain = 5

Let :

dozens of eggs sold = x

Bag of grains sold = 5x

Total sales worth = 243

Quantity sold * price

2* x + 5 * 5x

2x + 25x = 243

27x = 243

x = 243 / 27

x = 9

Bags of grains sold = 5x = 9*5 = 45 bags

Answers

Answer:

Im not like 100% sure but i think you answer is

y-6=3[x-(-2)]

y=6+3x+6

y=3x+12

And i believe that this is parallel to y

Answer:

y = 3x + 12

Step-by-step explanation:

Parallel lines have same slope

Given line

y = 3x + 5

The line that passes through (-2, 6) and with the slope of 3 is:

y - y₁ = m(x - x₁)y - 6 = 3(x - (-2))y - 6 = 3(x + 2)

Convert the equation into slope-intercept form:

y - 6 = 3x + 6y = 3x + 6 + 6y = 3x + 12
