Answer:
3, 1, - 1, - 3 and - 15
Step-by-step explanation:
To find the first 4 terms substitute n = 1, 2, 3, 4 into the rule, that is
a₁ = 5 - 2(1) = 5 - 2 = 3
a₂ = 5 - 2(2) = 5 - 4 = 1
a₃ = 5 - 2(3) = 5 - 6 = - 1
a₄ = 5 - 2(4) = 5 - 8 = - 3
The first 4 terms are 3, 1, - 1, - 3
For 10th term substitute n = 10 into the rule
a₁₀ = 5 - 2(10) = 5 - 20 = - 15
Write the standard equation of the circle.
Answer:
x^2 + y^2 = 4
Step-by-step explanation:
General for of a circle is x^2 + y^2 = r^2
The circle is centered at the origin and the radius is 2.
tell whether the slope is positive or negative. then find the slope.
Answer:
slope is negative
m=-1
Step-by-step explanation:
the slope of a line is positive if it passes through Quadrants III and I. The slope is negative if it passes through II and IV.
yes, this line passes through Quadrant I alongside II and IV, but it doesn't pass through Quadrant III (it has to pass through Quadrant III to be positive)
that means that the slope of this line must be negative
We can calculate the slope (m) with this formula:
(y2-y1)/(x2-x1)
we can pick two points- for example, (1,3) and (2,2)
label the points:
x1=1
y1=3
x2=2
y2=2
now substitute into the equation
m=(2-3)/(2-1)
m=-1/1
m=-1
the slope is -1
Hope this helps! :)

Jasmine has twice as much money as Madison. Madison has $6 less than Devanie. Together they have $54. How much money does Madison have?
Answer:
madision be $12
Jasmine be $24
And, the devanie be $18
Step-by-step explanation:
The computation is shown below:
Madison be x
Jasmine be 2x
Devanie be x + 6
And, the total is $54
Now the equation is
x + 2x + x + 6 = $54
4x = $48
x = $12
So madision be $12
Jasmine be $24
And, the devanie be $18

25 49/80 as a decimal
Answer:
25.6125
Step-by-step explanation:
since 25 is a whole number, it'd be 25.ˣˣˣˣ
now all you have to do it divide the fraction so 49 ÷ 80 = 0.6125
last step is to add ⇒ 25 + 0.6125 = 25.6125

After Selling 15 Lemonades, Jessica made 5 dollars. After selling 42 lemonades, she made 18.50
Answer:
y = 1/2x - 2.5
Step-by-step explanation:
(15, 5) and (42, 18.5)
Slope:
m=(y2-y1)/(x2-x1)
m=(18.5 - 5)/(42 - 15)
m = (13.5)/27
m = 1/2
y - y1 = m(x - x1)
y - 5 = 1/2(x - 15)
y - 5 = 1/2x - 7.5
y = 1/2x - 2.5
Answer:
2 or 1/2
Step-by-step explanation:
change in y over change in x
you didnt define what what x and what was y so ill provide both answers and you can figure which is correct
42-15/18.50-5 =27/13.5 =2
18.50-5/42-15 =13.5/27 =1/2

Two angles are complementary. The larger one is 3 times the measure of the
smaller one. What is the measure of the smaller angle in degrees?
Type just the numerical value.
Answer: 22.5°
Step-by-step explanation:
Complementary angles are the angles that when we add them together, they're equal to 90°.
Let the smaller angle be represented by x.
Then, the larger one will be 3 × x = 3x
We then add both angles together and equate them to 90°. Therefore,
x + 3x = 90°
4x = 90°
x = 90/4
x = 22.5°
The smaller angle is 22.5°

Answer:
a) KJL = 76⁰
b) LKM = 76/2 = 38⁰
Answer:
∠KJL = 76°
∠LKM = 38°
Step-by-step explanation:
since arc KL = 76°, ∠KJL also = 76° because central angles are congruent to their arcs.
∠LKM = 1/2 arc KL = 1/2(76°) = 38°
PLSS HELP I WILL GIVE BRAINLIEST PLSSS
Help me with this!!!!
Answer:
u = 21
Step-by-step explanation:
WX = XY because (VW = VY)
WX = u + 42
XY = 3u
u + 42 = 3u
42 = 3u - u
42 = 2u
u = 42 / 2
u = 21
Answer:
u = 21
Step-by-step explanation:
Consider triangle XWV and triange XYV
XV = XV (common)
Angle XVW = Angle XVY (given)
VW = VY (given)
∴triangle XWV ≅ triange XYV (SAS)
∴ XW = XY (corr. sides, ≅ triangles)
u + 42 = 3u
u = 21
The system of equations n=2p+3 and n=5p is graphed.what is the solution to the system of equations

How do you work out the circumference of this circle step by step?
Answer:

3.14 X 14cm = 43.96cm
Write the number in 2 equivalent forms as a fraction, decimal, or percent.0.40
Answer:
2/5 or 40%
Step-by-step explanation:
.40 is 40 hundredths or 40/100
40/100 can be reduced to 20/50 and reduced again to 10/25 and one more time to 2/5
Percentages are fractions out of 100 so 40/100 would be 40%.
In the figure, all lines intersect at point W.
What is the value of n?
Please help quick
Answer:
n = 15
Step-by-step explanation:
A straight line equals 180 degrees
Angle SWT is congruent to angle XWV meaning:
SWT (55 degrees) = XWV (55 degrees)
Set up an equation:
3n + 80 + 55 = 180
Combine like terms
3n + 135 = 180
Subtract both sides by 135 to isolate variable n
3n = 45
Divide both sides by 3 to isolate variable n
n = 15
