Brianna is graphing the function f(x) = x2 6x 5. what x-intercepts should brianna use to graph f(x)? –5 and –1 –5 and 1 –1 and 5 1 and 5

Answers

Answer 1

The value of the x of the equation x² + 2x = 24 is negative 5 and negative 1, then the correct option is A.

What is a factorization?

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

The expression equation is given below.

f(x) = x² + 6x + 5

On factorization, we have

     x² + 6x + 5 = 0

x² + 5x + x + 5 = 0

   (x + 5)(x + 1) =0                    

                    x = -1, -5

The value of x is –5 and –1.

question b only please



b) A different pattern is made using 20 straight lines
and 14 arcs.
The straight lines and arcs are made from metal.
20 straight lines cost £12
cost of one straight line : cost of one arc = 2 : 3
Work out the total cost of metal in the pattern.

Answers

Answer:

total cost= 24.6

Step-by-step explanation:

12 ÷ 20 = 0.6 per straight line

arc 0.6 × 3/2 = 0.9

12 + 0.9 × 14

12 + 12.6 = 24.6

The required cost of the metal used in the pattern is £24.6.

Given that,
A different pattern is made using 20 straight lines and 14 arcs.
The straight lines and arcs are made from metal. 20 straight lines cost £12 cost of one straight line is cost one arc = 2 : 3.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Let the cost of the total arcs be x,
As per the given condition,
The cost of the one straight line is 12/20 and cos if the one arc is x/14,
According to the question,
[12/20]/[x/14] = 2/3
12×14/20 = 2x / 3
x = £12.6
The total cost of a metal arc is £12.6
And the total cost of the metal line in the pattern is = £12.

Total cost of metal = 12 + 12.6 = £24.6

Thus, the required cost of the metal used in the pattern is £24.6.

x = 7.5, x = -5

Step-by-step explanation:

1. Plug a(2), b(-5), and c(-75) into the qudratic formula:

[tex]x_{1,2} =\frac{-(-5)+-\sqrt{(-5)^{2}-4(2)(-75) } }{2(2)}[/tex]

2. Find the square:

[tex]x_{1,2} =\frac{-(-5)+-\sqrt{25-4(2)(-75) } }{2(2)}[/tex]

[tex]x_{1,2} =\frac{-(-5)+-\sqrt{25+600} }{2(2)}[/tex]

[tex]x_{1,2} =\frac{-(-5)+-25 }{4}[/tex]

3. Separate the solutions:

[tex]x_{1} = \frac{-(-5)+25}{4} , x_{2} =\frac{-(-5)-25}{4}[/tex]

4. Solve for both:

[tex]x_{1} =\frac{5+25}{4} \\\\x_{1} =\frac{30}{4} \\\\x_{1} =\frac{15}{2}\\\\x_{1} =7.5[/tex]

--------------------

Which statement is true?

Here we need to see which statement regarding absolute value equations is true.

Here you can see that the fourth statement is:

-0.3*|3 + 8x| = 0.9   has no solutions.

Now, if you look at the left side of the above equation, the left side will always be negative, while the right side is positive, then the equation can't have a solution.

There is no value of x that makes that equation true, so it is true that the given equation has no solutions. This is the correct statement.

Answers

Answer:

ACUTE TRIANGLE

Step-by-step explanation:

If the sum of the squares of the two shorter sides of a triangle is greater than the square of the longest side, the triangle is acute. However, if the sum of the squares of the two shorter sides of a triangle is smaller than the square of the longest side, the triangle is obtuse.

Therefore, the triangle with sides 11, 9, and 7 is an acute triangle since 9² + 7² is greater than 11²

Derek lives in canada and enjoys herb gardening. his american friend sent him a guidebook for growing fresh herbs. the book says that it is best to cut bay shoots when they are 3.25 in long. if 1 mm is equivalent to 0.03937 in, how many millimeters long should the bay shoots be when derek cuts them? a. 8.26 mm b. 12.80 mm c. 82.55 mm d. 95.67 mm

Answers

When the bay shoots are 82.55 mm, Derek should cut them according to the guidebook for growing fresh herbs option (c) is correct.

What is unit conversion?

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, multiplication by a conversion factor.

The book says that it is best to cut bay shoots when they are 3.25 in long.

As it is given that the:

1 mm = 0.03937 in

To find how many millimeters long should the bay shoots be when Derek cuts them, we must convert 3.25 in to mm

From the 1 mm = 0.03937 in, we can find how many mm is there in 1 in;

[tex]\rm 1 \ in= \frac{1}{0.03937} \ mm[/tex]

To convert 3.25 in into mm, we must multiply it by 1/0.03937

= 3.25×(1/0.03937)

= 82.55 mm

Thus, when the bay shoots are 82.55 mm, Derek should cut them according to the guidebook for growing fresh herbs option (c) is correct.

What is the value of x?

Answers

Answer:

Step-by-step explanation:

Sum of all angles of triangle = 180

17x + 10x -5 +  50 = 180

Combine like terms

27x + 45 = 180

To find the valu of x, we have to isolate x. To isloate x

Step 1: Subtract 45 from both sides

           27x = 180 - 45

           27x = 135

Step 2: Divide both sides by 27

               x = 135/27

x = 5

Which function represents the graph

Answers

The absolute value function represented by the graph is:

y = -3*|x|

So the correct option is B.

Which function represents the graph?

In the graph, we can see a "V" shape, which belongs to the absolute value functions, but this graph opens down, so our function will be something like:

y = -a*|x - b|

The value of b is the value of x where we have the vertex, in this case, is at x = 0, so b = 0

y = -a*|x|

To get the value of 1, we ise one of the points that we can see on the graph. For example, for x = 1, we have y = -3, replacing that we get:

-3 = -a*|1| = -a

3 = a

So we can conclude that our function is:

y = -3*|x|

So the correct option is B.
