what is the slope of 9,12 and 7,4

Answers

Answer 1

Answer:

m=3/16

Step-by-step explanation:

Answer 2

Answer:

4

Step-by-step explanation:

y2-y1 / x2-x1

"y2" in this expression is 4 "y1" is 12

4 - 12 = -8

"x2" = 7 "x1" = 9

7 - 9 = -2

Then we divide the difference of the 2 y values and of the x values,

-8 divided by -2 = 4

A. (3+ 7i,3 - 7i)
B. (2+19i,2 - 19i)
c. (2+9i,2 - 9i)
D. (7+3i,7-3i)

Answers

9514 1404 393

Answer:

 D.  7 +3i, 7 -3i

Step-by-step explanation:

When the leading coefficient of the quadratic is 1, as it is here, the sum of the roots is equal to the opposite of the coefficient of the x-term. So, we need the sum of roots to be -(-14) = 14.

In each case, the imaginary parts cancel when the roots are added. The real parts of the roots are the same, so the sum of roots is double the real part of one of the roots. In order for that to be 14, the real part of the root must be 7.

Only answer choice D matches this requirement.

Algebraic solution

  x^2 -14x +58 = 0 . . . . given

  (x -7)^2 = -9 . . . . . . . subtract 9 and write as a square

  x = 7 ± 3i . . . . . . . . square root and add 7

______

Additional comment

When p and q are roots, (x-p) and (x-q) are factors. The expansion of the factored form is ...

  (x -p)(x -q) = x^2 -(p+q)x +pq = 0

That is, the constant term is the product of the roots, and the linear (x) term coefficient is the opposite of the sum of the roots. This can help you check quickly if an offered choice of roots is applicable to the given equation. This is also the basis of the thinking used to factor the equation.

if ∆ACB ≅ ∆DCE, ∠ABC=61°, ∠BCA=57° and ∠CDE=2x

Answers

ABC=CDE when ABC=61 then CDE=2X 2X=61 --> X=61/2=30.5

The value of x would be equal to 30.5

What are vertical angles?

Each of the pairs of the opposite angles made by two intersecting lines are called vertical angles.

We are given that if ∆ACB ≅ ∆DCE,

∠ABC=61°,

∠BCA=57°

∠CDE=2x

Therefore,

ABC = CDE

then CDE = 2X

2X = 61

X=61/2

X =30.5

Hence, the value of x would be equal to 30.5

The next step is to combine like terms. We can factor out g, so the coefficients are easier to see and combine.

The error is 1 3/10 was combined with -2/10 as a constant instead of being combined with -4/5 as a coefficient of g.

What is the arithmetic operator?

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.

Multiplication = to multiply any two or more numbers or variables called multiplication.

Summation = addition of two or more numbers or variable

As per the given,

Price of recliner = $500

Financed for $30 for 24 months

Total cost = 30 x 24 = $720

Finance charge = $720 - $500 = $220

Hence "The total cost of the recliner is $720 thus the finance charge will be $220".

Step-by-step explanation:

a) mean: add all numbers and then divide them.. so:

3+9+10+5+8+5+9+11+10+3+10= 83

83 divided by 11 = 83/11 or 7 4/11

b) median: the middle number of the sequence but put in order first.. so:

smallest to largest: 3,3,5,5,8,9,9,10,10,10,11

so then middle number: 9

c) mode: most frequent (popular) figure/number.. so:

most frequent value: 10

d) range: difference between smallest number and largest number

On a hot summer day, Roy and his friends decided to have a water fight. They threw water balloons for 52 minutes. When all the water balloons were gone, they sprayed water with hoses for 42 minutes. The water fight ended at 5:27 P.M. when Roy's dad showed up with ice cream. What time did the water fight start?

Answers

Answer:

3:53 P.M. (15:53)

Step-by-step explanation:

x + 52 + 42 = the time (5:27 pm)

First we try to remove the extra minutes from 5:27pm

42 min (the second part of the fight) - 27 (the minutes from 5:27 pm) = 15

Now we have 15 minutes to take away and 60 minutes from 5pm

60 (5pm) - 15 = 45

Now once again we remove the extra minutes

52-45 (4:45pm) = 7

Then we take away the 7 minutes from 4pm

60 (4pm)- 7= 53

Answers

Answer:

∠ BXC = 70°

Step-by-step explanation:

∠ XBC and ∠ AXY are corresponding angles and are congruent, then

∠ XBC = 55°

Since XB = XC , then Δ XBC is isosceles and the 2 base angles are congruent.

∠ BXC = 180° - (55 + 55)° ← angle sum of triangle

∠ BXC = 180° - 110° = 70°

What finds the optimum value for a target variable by repeatedly changing other variables, subject to specified constraints

Answers

What finds the optimum value for a target variable by repeatedly changing other variables, subject to specified constraints, is an extension of goal-seeking analysis.

Goal seeking refers to a set of scientific methodologies aimed at determining the conditions for obtaining a predetermined end state. This notion, also called what-if analysis or back solving, was established in the 1950s in the fields of psychology and computer science.

Thus, the researchers are in charge of generating a favorable context for the generation of the expected results, with the aim of analyzing them once produced, and obtaining scientific knowledge.
