solve: x2 + 8x - 9 = 0
please i need it urgently
Answers
Answer:
x = 1 or x = -9
Step-by-step explanation:
Solve for x over the real numbers:
x^2 + 8 x - 9 = 0
Hint: | Solve the quadratic equation by completing the square.
Add 9 to both sides:
x^2 + 8 x = 9
Hint: | Take one half of the coefficient of x and square it, then add it to both sides.
Add 16 to both sides:
x^2 + 8 x + 16 = 25
Hint: | Factor the left hand side.
Write the left hand side as a square:
(x + 4)^2 = 25
Hint: | Eliminate the exponent on the left hand side.
Take the square root of both sides:
x + 4 = 5 or x + 4 = -5
Hint: | Look at the first equation: Solve for x.
Subtract 4 from both sides:
x = 1 or x + 4 = -5
Hint: | Look at the second equation: Solve for x.
Subtract 4 from both sides:
Answer: x = 1 or x = -9
(HELP) What is the domain and range of this parabola?
Answers
Answer:
D: [0,8]
R: [0,3]
Step-by-step explanation:
The domain is the x-values covered by the graph, while the range is the y-values. So to find each, find the lowest and highest x and y value; since this graph is continuous the domain and range will include all values between these points. In this case, the lowest x is 0 and the highest is 8; the lowest y is 0 and the highest is 3. Then to write the answer write is from least to greatest, finally, surround the point by a parenthesis or bracket. The difference is that parenthesis means the value is not included while a bracket means it is. On this graph all points are included, therefore brackets should be used.

Emelina loaded 96 trucks in 8 hours. At that rate, how many trucks
would she load in 15 minutes?
Answers
Answer:
3
Step-by-step explanation:
60 × 8 = 480 (mins)
96 (trucks) = 480 (mins)
÷32 (I got this number by dividing 480 by the desired amount of mins which was 15)
3 = 15
So 3 trucks would have been loaded in 15 mins
The numbers 20 through 30 are written on cards and placed in a box. Explain whether the events of choosing a number that is a multiple of 3 or choosing a number that is a multiple of 4 are mutually exclusive.
A. Mutually Exclusive
B. Not Mutually Exclusive
Answers
Answer:
A. Mutually Exclusive is the correct answer
The events of choosing a number that is a multiple of [tex]3[/tex] or choosing a number that is a multiple of [tex]4[/tex] are not mutually exclusive.
What is Mutually Exclusive ?Mutually Exclusive means when two sets have no common elements.
What is Not Mutually Exclusive ?Not Mutually Exclusive means when two sets share common elements.
We have,
Cards numbered [tex]20[/tex] to [tex]30[/tex].
Let's
Set [tex]A =[/tex] Multiple of [tex]3[/tex]
i.e. Set [tex]A = \ \{ 21, 24,27,30\}[/tex]
Set [tex]B =[/tex] Multiple of [tex]4[/tex]
i.e. Set [tex]B = \{20,24,28\}[/tex]
So, Set [tex]A[/tex] and Set [tex]B[/tex] have common element [tex]24[/tex], so we call them Not Mutually Exclusive, from the mentioned definition we find out this.
Hence, we can say that the events of choosing a number that is a multiple of [tex]3[/tex] or choosing a number that is a multiple of [tex]4[/tex] are not mutually exclusive.

A function rule takes an input(x) and coverts into an output(y), by increasing 4 times the inpuy by 36. Write an equation for the rule and determine the output for this rule when the input is 3
Answers
Answer:
[tex]y = 4x + 36[/tex]
[tex]y = 48[/tex] when [tex]x = 3[/tex]
Step-by-step explanation:
Given
x = input
y = output
Required
Determine the equation of y
The process to get y is as follows:
Multiply x by 4: x * 4
Increase the result by 36: x * 4 + 36
Hence:
[tex]y = x * 4 + 36[/tex]
[tex]y = 4x + 36[/tex]
Solving y when x = 3
Substitute 3 for x in [tex]y = 4x + 36[/tex]
[tex]y = 4 * 3 + 36[/tex]
[tex]y = 12 + 36[/tex]
[tex]y = 48[/tex]
The Mallards pay their two quarterbacks $7.2 million and $1.4 million. If the team salary is $33 million a year and their budget for quarterbacks is 25% of total salaries. Are they over budget? a) Yes b) No
Answers
Answer:
a) Yes
Step-by-step explanation:
The computation is shown below:
Given that
Their two quarterbacks is $7.2 million and $1.4 million
Its total is
= $7.2 million + $1.4 million
= $8.6 million
Now if the team salary is $33 million
And their budget is 25% of total salaries
i.e.
= $33 million × 25%
= $8.25 million
So as we can see that it it overbudget as the target is $8.25 million but it is $8.6 million
SO, the correct option is a.

Use the figure at the right to answer questions 9-12.
Answers
Answer:
9.) 5x - 18 = 4x + 7 10.) x = 25 11.) m∠MNQ = 107° 12.) m∠MNR = 73°
Step-by-step explanation:
9. & 10.)
∠MNQ and ∠RNP are vertical angles meaning they are equivalent to each other. Knowing that, we can set their values equal to each other and solve for x.
5x - 18 = 4x + 7 (Given)
x - 18 = 7 (Subtract 4x on both sides)
x = 25 (Add 18 on both sides)
Therefore, we know the equation is 5x - 18 = 4x + 7 and we know that x = 25.
Now we can solve for the angles.
11.)
5(25) - 18
125 - 18 = 107
Therefore, m∠MNQ = 107°.
12.)
∠MNR and ∠MNQ are supplementary angles meaning their angles will add up to 180°
∠MNR + 107 = 180
∠MNR = 73
Therefore, m∠MNR = 73°.
Write an equation to find x by substituting.

You can paint 75 square feet of a surface every 45 minutes. Determine how long it takes you to paint a wall with the given dimensions. 8 ft $\times$ 5 ft
Answers
Answer:
24 minutes
Step-by-step explanation:
The Dimensions of the wall are given as:
8ft × 5ft = 40ft² or 40 square feet
We are told that: You can paint 75 square feet of a surface every 45 minutes.
Hence:
75 ft² = 45 minutes
40 ft² = x minutes
Cross Multiply
75 ft² × x = 40 ft² × 45 minutes
x = 40 ft² × 45 minutes/75 ft²
x = 24 minutes
Therefore, It will takes you 24 minutes to paint a wall with dimensions 8ft × 5 ft

a^2 + b^2 = c^2
4^2 + 5^2 = c^2
16 + 25 = c^2
41 =c^2
6.403124237432849 = c
So now since we have the answer, we need to figure out if this result and 6 are equal.
6^2 = 36
25 + 16 = 41
41 and 36 are not equivalent so if the case is that u want me to find the Pythagorean theorem, then the answer is that they aren’t equal. And the real answer is that c equals 6.403124237432849. Which means that 4in, 5in, 6in is not the correct order. And that 16in, 25, 41 is the correct order.
