Answers
Answer:
59°Step-by-step explanation:
∠C and ∠A are supplementary angles so as ∠B with ∠D, as opposite angles of a cyclic quadrilateral.Supplementary angles sum to 180°First find the value of x:
2x + 3 + 4x + 3 = 1806x + 6 = 180°6x = 174°x = 29°Find the measure of ∠C:
m∠C = 2*29° + 1° = 59°Opposite angles of a cyclic quadrilateral are supplementary
m<B+m<D=1802x+3+4x+3=1806x+6=1806x=174x=29m<C

find the measure of m<N
Answers
Answer:
m<N = 10°
Step-by-step explanation:
If the vertex of the inscribied angle is in the circumference, its measure if half the measure of the arc:
[tex]m < n = \frac{mlm}{2} [/tex]
NL is the diameter of the circle, so arc NML is 180° (half the circle). We know the measure of arc NM:
[tex]mnm +mlm \: = mnml \\ 160 + mlm = 180 \\ mlm = 180 - 160 \\ mlm = 20[/tex]
So, angle N is:
[tex]m < n = 10[/tex]
2x2-12x +8=3 rounding to the nearest hundredth
Answers
Answer:
x=3/4 as fraction form.
x=0.75 as decimal form.
Step-by-step explanation:
Step 1.
2x2-12x+8=3
2x2=4
Step 2.
4-12x+8=3
4+8=12
12-12x=3
Step 3.
12-12x=3
(Subtract 12 from both sides.)
-12x=3-12
-12x=-9
Step 4.
-12x=-9 will equal:
0.75 or 3/4
But rounded up will equal 1 whole.

Jordan invests £12500 into
His bank account.
He receives 8.5% per year simple interest.
How much will Jordan have after 3years?
Give your answer to the nearest penny
where appropriate.
Answers
Answer:
Jordan will have $15687.50 after 3 years.
Step-by-step explanation:
First, we have to find the amount of interest Jordan has by using the following formula,
simple interest = $12,500 * 8.5% * 3
since the interest rate is obviously a percentage, we convert it into a decimal.
simple interest = $12,500 * 8.5% * 3
simple interest = $12,500 * 0.085 * 3
now that the numbers are the way it's supposed to be, we multiply them all together.
simple interest = $12,500 * 0.085 * 3
simple interest = $1062.50 * 3 (here, we multiply the first two numbers before multiplying it by 3 so we will have two numbers remaining which is easier to deal with without all three numbers together)
simple interest = $3187.50
Jordan has $3185.50 simple interest.
however, this is not the final answer since it asks how much he has AFTER 3 years. think about it.. would you really have $3187.50 AFTER 3 years with investing $12,500 into your account? no, since the values have such big difference to each other. we have to add the amount of interest by the principal by using the following formula,
total amount = principal + simple interest
now, we substitute the numbers in.
total amount = principal + simple interest
total amount = $12,500 + $3185.70
total amount = $15.687.50
Therefore, Jordan will have $15,687.50 after 3 years.

What is the slope of the line that passes through the points (5, 1) and (2, -7)?
Answers
So you get -6/-3, which equals 2
SLOPE IS 2
Answer:
m [ slope ] = 8/3
Step-by-step explanation:
What is the slope of the line that passes through the points (5, 1) and (2, -7)?
m = ∆y / ∆x
m = y₂ – y₁ / x₂ – x₁
| (5, 1) → (x₁, y₁) | (2, -7) → (x₂, y₂) |
[each coordinate will correspond (directly go to) to the variables shown]
m = (-7) – (1) / (2) – (5)
m = -8 / -3
m = 8 / 3
This means that this line has a rise of 8 and a run of 3.
Up 8 and right 3 proportionally, it would touch the opposite corners of a plane that was 8 by 3 units.
Slope can be thought of as the steepness of a line, the greater the slope, the greater the steepness.
These points are generally known as cartesian coordinates.
____________
Once you have the slope, you can back track from one of the coordinates to find the equation of the line.
Just multiply the slope by the x of either coordinate, make it opposite, and then add that to the y of that coordinate to get b [the y-intercept; where it crosses the y axis, x is always 0]
Since (2, -7) is closer to the y axis than (5, 1) it is more convenient.
In (2, -7), 2 is the x variable and -7 is the y variable.
-mx + y = (-8/3)(2) + (-7) = -16/3 + (-21/3)
21/3 is the same as 7 [so it will have a common denominator].
-16 + -21 / 3 = -37/3 = b
Thus this line has an equation of
y = mx + b
↓ ↓
y = 8/3x – 37/3.
__________________________
Or you can refer to point slope which is what is taught:
y – y₁ = m(x – x₁).
You can tell that there are some similarities to this and the slope formula.
m = ( y₂ – y₁ / x₂ – x₁ ) →
m × ( x₂ – x₁ ) =
( y₂ – y₁ / x₂ – x₁ ) × ( x₂ – x₁ )
[multiply the denominator by both sides]
m ( x₂ – x₁ ) = y₂ – y₁
[x₂, and y₂ can just be x and y since you only need the initial coordinate and slope, because the second coordinate can be anything along that line]
m ( x – x₁ ) = y – y₁ →
y – y₁ = m(x – x₁)
[symmetric property of equality]

x=3/74
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
20/3x=1/2x+1/4
Step 2: Subtract 1/2x from both sides.
20/3x-1/2x=1/2x+1/4-1/2x
37/6x=1/4
Step 3: Multiply both sides by 6/37.
(6/37)*(37/6x)=(6/37)*(1/4)
x=3/74
Thus, your answer will be x=3/74.
