Answer:-5
Step-by-step explanation:
You need to distribute on both sides so u get
9c-15=20-2c
Move variable to left side and change the sign
-9c+2c-15=20
Move constant to right side and change the sign
-9c+2c=20+15
Connect like terms
-7c=35
Divide
C=-5

Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope-Intercept Form: y = mx + b
m - slope b - y-interceptStandard Form: Ax + By = C
Step-by-step explanation:
Step 1: Define
Find points from graph.
x-int (3, 0)
y-int (0, -5)
Step 2: Find slope m
Substitute: [tex]m=\frac{-5-0}{0-3}[/tex]Subtract: [tex]m=\frac{-5}{-3}[/tex]Simplify: [tex]m=\frac{5}{3}[/tex]Step 3: Write Slope-Intercept Form
y = 5/3x - 5
Step 4: Find Standard Form
Subtract 5/3x on both sides: -5/3x + y = -5Multiply both sides by -1: 5/3x - y = 5And we have our answer!
Your subtotal at the store was $58.89. You have a 30% off coupon. If the sales tax rate is 5.5%, what is the total price for your shopping trip?
Answer:
$43.48
Step-by-step explanation:
58.89x.30=17.68
58.89-17.68=41.21
41.21x.055=2.27
41.21+2.27= $43.48
Answer:
$43.49
Step-by-step explanation:
When you take of 30%, multiply by 0.7
When you add 5.5%, multiply by 1.055
Start with $58.89
Take off 30%: 0.7 * $58.89 = $41.22
Add 5.5%: 1.055 * $41.22 = $43.49

Triangle CEN is congruent to Triangle CED. What property is shown by line segment CE being congruent to line segment CE?
Answer:
C. Reflexive property
Step-by-step explanation:
When a line segment is congruent or the same as itself, it is considered to have a property known as reflexive property.
This means line segment CE is a mirror image of itself. Therefore, line segment CE is congruent to line segment CE.
Line segment CE is what divides the figure given into two equal halves, making both parts congruent to each other.
If a circle with a diameter of 4 inches rotates 1000°, what distance will any one spot on
its edge actually travel?
We first convert from degrees to radians multiplying by π/180:
θ = 1000° × π/180 = 17.45 rad
The radius is:
r = d/2 = 4 in /2 = 2 inch
So, The distance traveled is given by the product of the angle in radians and the radius. This is:
d = θr = (17.45 rad)(2 inch) = 34.9 inch

An object is attached to a spring that is stretched and released. The equation d = a (cos(bt)) models the distance, d, of the object in inches above or below the rest position as a function of time, t, in seconds. If a = 5 and b = 5 Approximately when will the object be 2 inches above the rest position? Round to the nearest hundredth, if necessary.
Answer:
The object will be 2 inches above the rest position when at approximately 0.23 seconds
Step-by-step explanation:
The given parameters are;
The equation that models the distance, d, of the object in inches above or below the rest position = a×(cos(b·t))
If a = 5 and b = 5, we have;
d = 5 × (cos(5 × t))
When the object is approximately 2 inches above the ground, we have;
d = 2 = 5 × (cos(5 × t))
cos(5 × t) = 2/5
5 × t = cos⁻¹(2/5) ≈ 1.16
t = (cos⁻¹(2/5))/5 ≈ 1.16/5
t ≈ 0.23 s
The object will be 2 inches above the rest position when t ≈ 0.23 s.

YW is the perpendicular bisector of ZT.
If TW = 3, YW = 8, and XZ = 12. Find XY.
Answer:
XY = 17 UNIT
Step-by-step explanation:
Given:
TW = 3
YW = 8
XZ = 12
Find:
XY
Computation:
TW = ZW = 3
So,
XW = 12 + 3
XW = 15
So
XY = √XW²+YW²
XY = √15²+8²
XY = √289
XY = 17 UNIT
Applying the definition of perpendicular bisector and the Pythagorean Theorem, the value of XY is calculated as: 17 units.
Recall:
A perpendicular bisector of a line divides a line segment into two equal halves.Also, it forms two opposite right angles on the point of bisection.Considering the diagram attached below, we are given that:
[tex]TW = 3\\\\YW = 8\\\\XZ = 12[/tex]
We need to find the length of XY.Applying the Pythagorean theorem:
[tex]XY = \sqrt{XW^2 + YW^2}[/tex]
XW = XZ + WZ
XZ = 12 (given)
WZ = TW = 3 (congruent segments)
Thus:XW = 12 + 3
XW = 15
Plug in the values of XW and YW into [tex]XY = \sqrt{XW^2 + YW^2}[/tex]
Thus:[tex]XY = \sqrt{15^2 + 8^2}\\\\\mathbf{XY = 17}[/tex]

what's the answer to this quadratic equation
(x - 18)^2 = 1
Answer:
x=17 or x=19
Step-by-step explanation:
(x−18)^2=1
First, simplify both sides of the equation.
x*2−36x+324=1
Then subtract 1 from both sides.
x^2−36x+324−1=1−1
x^2−36x+323=0
Factor left side of equation.
(x−17)(x−19)=0
Then set factors equal to 0.
x−17=0 or x−19=0
x=17 or x=19
Answer:
Its either x=17 or x=19

Find angle YWX using the perpendicular or angle bisector method.
Answer:
x = 5
Step-by-step explanation:
9x - 28 = 5x - 8 (because Y and X are equal, and XZ and YZ are equal)
add 8 to both sides
9x - 20 = 5x
subtract 9x from both sides
-20 = -4x
divide 4x from both sides
5 = x
x = 5

Answer:
-457.96
Step-by-step explanation:
Step-by-step explanation:
273.15 + °C = K
°C = K - 273.15
0.95K to °C = 0.95 - 273.15 = -272.2°C
°C to °F
(9/5 °C) + 32 = °F
(9/5 × -272.2) + 32 = °F

I need to know how to graph and use a table to solve for y=3x+0
Answer:
Step-by-step explanation:
On a table, you'd have two columns: one for your input(x) and one for your output(y). If given an x value, put it into the equation to solve for y, and if you have a y value, put it into the equation for x. You can also come up with your own x values and put them into the equation if you need to create a table from scratch I'm not sure what you're asking but this will help you fill in a table. Here's and example for this equation.
X Y
1 3
2 6
3 9
Graphs are pretty simple. Just find a value on the x-axis (horizontal), find the point on the line above or below this value, and look at what number it is for the y value. You can do this backwards if you need to find y when given x.
