Answer:
The slope is zero.
Step-by-step explanation:
Imagine the graph. [tex]y=3[/tex] would simply be a horizontal line. All horizontal lines have slopes of 0. You can also use the slope formula if necessary to try it out.
On the other hand, if the line was vertical (e.g. [tex]x=3[/tex]), then the slope would be undefined.
Answer: The line y=3 is a horizontal line, and a horizontal line has a slope of zero. The only lines parallel to a horizontal line are other horizontal lines. Therefore, there is no slope.
Step-by-step explanation: y=3 rewritten as y=0x+3
For a line equation for the form of y=mx+b, the slope is m
m=0
Given that 3m=2c-5k,express c in terms of k and m.
Answer:
The answer is
[tex]c = \frac{3m + 5k}{2} [/tex]
Step-by-step explanation:
You have to move all the unrelated terms to the other side :
[tex]3m = 2c - 5k[/tex]
[tex]3m + 5k = 2c[/tex]
[tex]2c = 3m + 5k[/tex]
Next you have to divide it by 2 :
[tex]c = \frac{3m + 5k}{2} [/tex]

Solve the following inequality:
7 < 6.4+3(-6x – 4.3)
Answer:
X < -0.84
Step-by-step explanation:
Write the quadratic function in the form f(x)=a(x-h)^2+k. Then, give the vertex of its graph. Finally, graph the function by plotting the vertex and four additional points, two on each side of the vertex. f(x)=-2x^2+16x-35
Answer:
[tex]f(x) = -2(x - 4)^2 -3[/tex]
Vertex = (4, -3)
Graph in the image attached, additional points:
(2, -11), (3, -5), (5, -5), (6, -11)
Step-by-step explanation:
The vertex of f(x) can be found using the formula:
[tex]x_{vertex} = -b/2a[/tex]
[tex]x_{vertex} = -16 / (-4)[/tex]
[tex]x_{vertex} = 4[/tex]
to find y_vertex, we use x_vertex in f(x):
[tex]f(x_{vertex}) = -2 * 4^2 + 16*4 - 35[/tex]
[tex]f(x_{vertex}) = -3[/tex]
So the vertex is (4, -3)
To write the function in the form [tex]f(x)=a(x-h)^2+k[/tex], we just need to calculate h = -b/2a and then find k:
[tex]h = -b/2a = -16/(-4) = 4[/tex]
[tex]f(x) = -2(x - 4)^2 + k = -2(x^2 - 8x + 16) + k = -2x^2 + 16x - 32 + k[/tex]
Comparing both forms of f(x), we have:
[tex]-32 + k = -35[/tex]
[tex]k = -3[/tex]
So we have:
[tex]f(x) = -2(x - 4)^2 -3[/tex]
Now let's find the four additional points.
Two points to the left: x = 3 and x = 2
[tex]f(3) = -2 * 3^2 + 16*3 - 35 = -5[/tex]
[tex]f(2) = -2 * 2^2 + 16*2 - 35 = -11[/tex]
Two points to the right: x = 5 and x = 6
[tex]f(5) = -2 * 5^2 + 16*5 - 35 = -5[/tex]
[tex]f(6) = -2 * 6^2 + 16*6 - 35 = -11[/tex]
3(x + 6) – 2(x – 4) > 5(x + 2)
Answer:
4 >x
Step-by-step explanation:
3(x + 6) – 2(x – 4) > 5(x + 2)
Distribute
3x+18 -2x+8 > 5x+10
Combine like terms
x +26 > 5x+10
Subtract x from each side
x+26-x > 5x-x+10
26 > 4x+10
Subtract 10 from each side
26-10 >4x+10-10
16 >4x
Divide each side by 4
16/4 >4x/4
4 >x

Can someone please help me with the slope?
Answer:
1/2
Step-by-step explanation:
For each two units that this line moves to the right, it rises one. This means that it has a slope of 1/2. Hope this helps!
Here’s a graph of a linear function. Write the equation that describes that function. Express it in slope intercept form.
slope = 1/2, y intercept = 3
==============================================================
Work Shown:
Pick any two points you want on the line.
I'll pick the two points (0,3) which is the y intercept and also the point (2,4).
------
Find the slope of the line through (x1,y1) = (0,3) and (x2,y2) = (2,4)
m = (y2 - y1)/(x2 - x1)
m = (4 - 3)/(2 - 0)
m = 1/2 is the slope
slope = rise/run = 1/2
rise/run = 1/2 means rise = 1 and run = 2.
This means we go up 1 unit each time we move to the right 2 units.
-----
Since the slope is m = 1/2 and the y intercept is b = 3, we can say
y = mx+b
y = (1/2)x+3
this is the same as y = 0.5x+3 since 1/2 = 0.5

Circle T is shown. Line segments T S, T R, T Q, and T P are radii. Lines are drawn to connect points S and R and points P and Q to form secants. Angles R T S and Q T P are congruent. What is true regarding two adjacent arcs created by two intersecting diameters? They always have equal measures. The difference of their measures is 90°. The sum of their measures is 180°. Their measures cannot be equal.
Answer: the sum of their measures is 180 degrees
Step-by-step explanation:
I just got it right
The angles R T S and Q T P are vertically opposite angles. So that they always have equal measures.
Circle :In given circle, T is center of circle .
and RP and SQ are diameter of circle which are intersecting at center T.
The diagram of circle is attached below.
In the diagram of circle, Angles R T S and Q T P are congruent.
So that, [tex]\angle RTS=\angle QTP\\\\[/tex]
Since, both diameter are crossing each other.
So that, Angles R T S and Q T P are vertically opposite angles.
Therefore, they always have equal measures.

Answer:
x² + x - 8
Step-by-step explanation:
(f . g)(x) is same with (f(g(x))
so insert the g(x) equation into f(x) and change the x on it
f(g(x)) = g(x) - 2
f(g(x)) = (x² + x - 6) - 2 = x² + x - 6 - 2 = x² + x -8
so
(f.g)(x) is x² + x - 8

Line CD passes through points C(3, -5) and D(6, 0) . what is the equation of the line CD in standard form?
Answer:
Option 2: 5x - 3y = 30
Step-by-step explanation:
Step 1: Find slope
(0-(-5))/(6-3) = 5/3
Step 2: Find b
y = 5/3x + b
0 = 5/3(6) + b
b = -10
Step 3: Write in slope-intercept form
y = 5/3x - 10
Step 4: Move x over
-5/3x + y = -10
Step 5: Multiply by -3 on both sides
5x - 3y = 30

Harry buys a boat in 2010. He plans on selling it in 2020. In 2010, the boat costs $20,000. The value of the boat depreciates over time
as is shown in the graph below, where the y-axis represents the value of the boat, in dollars, and the x-axis represents the number of
years since 2010.
Answer:
The initial value of the boat was $20,000
The percent decrease per year of the value of the boat is 10%.
The interval on which the value of the boat is decreasing while Harry has it is (0,10)
Step-by-step explanation:
It is given that the boat costs $20,000 in 2010 when x = 0. So, the initial value of the boat was $20,000.
Next, find the percent decrease per year of the value of the boat. Consider the general form of an exponential equation, y = a(b)x, where a is the initial value of the boat, b is the base of the exponent, x is the number of years after 2010, and y is the value of the boat, in dollars.
Consider the point (1 , 18,000) which lies on the graph of this situation. Substitute x = 1, y = 18,000, and a = 20,000 into the exponential equation and isolate b.
Recall that for exponential decay, b = 1 - r where r represents the decay rate. Substitute b = 0.9 into this equation and solve for r.
So, the decay rate is 0.1, and the percent decrease per year of the value of the boat is 10%.
Harry bought the boat in 2010, and plans on selling it after 10 years in 2020. Therefore, the interval on which the value of the boat is decreasing while Harry has it is [0, 10].

please tomorrow exam - John is twice as old as his friend Peter. Peter is 5 years older than Alice. In 5 years, John will be three times as old as Alice. How old is Peter now?
Answer:
Peter is 20 years old
Step-by-step explanation:
John= 2(Peter's age) (j=2p)
Peter= (Alice's age + 5) (P= A+5)
Okay, so let's substitute the equations now:
John= 2(Alice + 5)
So the equation for 5 years from now is:
2(A+5) + 5 = 3a (because he is 3 times as old as alice)
so, let's solve for that equation:
2a + 10 + 5 = 3a
subtract 2a from both sides:
15= a
so, Alice is going to be 15 years old, so now we can solve for Peter's age:
P= A + 5
P= 15 + 5
P = 20
Peter is 20 years old
I hope this helps! :)
