Step-by-step explanation:
2x + 3 > 13
Whats the answer plz help
Answer:
In this case, you can simply treat the > sign like an = sign. The only time you would need to worry about is when multiplying or dividing by negative numbers.
2x + 3 > 13
2x + 3 - 3 > 13 - 3
2x > 10
2x / 2 > 10 / 2
x > 5

How do I find the slope of a line?
Answer:
In order to find the slope of the line, find two points that are on the line and use the equation: m=(y2-y1)/(x2-x1). The 2 points should be whole numbers.
Answer:
Step-by-step explanation:
y2-y1
he first equation you need is m= ---------
x2-x1
x1 , y1 x2, y2
then you label the point like this ex: ( 2, -5) (1, 3)
and then place them in the places of the original eqatuion and you get your answer. but then you can simplify if you need too.

Answer:
32(cos(18))=x
Step-by-step explanation:
cos(18)=x/32
32(cos(18))=x
Type in calculator for decimal answer.
Answer:
x = 32cos(18) = 30.434
Step-by-step explanation:
Use the cosine function (adjacent / hypotenuse)
cos(18) = [tex]\frac{x}{32}[/tex]
x = 32cos(18) = 30.434

Emma is going to invest in an account paying an interest rate of 6.7% compounded continuously. How much would Emma need to invest, to the nearest hundred dollars, for the value of the account to reach $11,000 in 18 years?
Answer:
$3300 to nearest hundred.
Step-by-step explanation:
Let the amount required be $A then
11000 = Ae^(0.067*18)
A = 11000 / e^(0.067*18)
= 3293

State the x-intercept, y intercept and the slope for each graph. Then write an equation in slope intercept form
Answer:
1.
x-intercept = 8/5
y-intercept = -4
m = 1.5 (or 5/2)
equation: y = 1.5x - 4
2.
x-intercept = -1/2
y-intercept = -3
m = -6
equation: y = -6x - 3
Useful things to note:
Definition of a y-intercept: The y value when x = 0.
Definition of a x-intercept: The x value when y = 0.
Definition of the slope-intercept form: y = mx + b
b = the y-interceptStep-by-step explanation:
1.
We don't know the x-intercept yet, but we can easily find the y-intercept.
So on the x = 0 line, we see there's a point right at (0, -4). So, the y-intercept is at -4.
The other point that's given is (2, 1). This is useful for getting the slope-intercept form.
y = mx + b
Lets solve for m.
When solving for m in the slope-intercept form, we replace x and y with an available point. For this we'll use (2, 1). We already know that b = the y-intercept, which is -4. Combining these two facts, we get this equation:
1 = 2m - 4
Let's solve this:
1 = 2m - 4
1 + 4 = 2m -4 + 4
5 = 2m
5/2 = 2m/2
1 1/2 = m
or
1.5 = m
Now that we have m, we can easily get the equation!
b = -4
m = 1.5
replacing those in the slope-intercept formula, we get:
y = mx + b
y = (1.5)x + (-4)
equation: y = 1.5x - 4
in order to finally find the x-intercept, we find where x is when y = 0. (I'm going to use m = 5/2 for easiest convenience. All of those values work though :) )
y = 5/2x - 4
make y = 0
0 = 5/2x - 4
0 + 4 = 5/2x - 4 + 4
4 = 5/2x
4*(2/1) = 5/2x*(2/1)
8 = 5x
8/5 = 5x/5
8/5 = x
2.
We don't know the x-intercept yet, but we can easily find the y-intercept.
So on the x = 0 line, we see there's a point right at (0, -3). So, the y-intercept is at -3.
The other point that's given is (-1, 3). This is useful for getting the slope-intercept form.
y = mx + b
Lets solve for m.
When solving for m in the slope-intercept form, we replace x and y with an available point. For this we'll use (-1, 3). We already know that b = the y-intercept, which is -3. Combining these two facts, we get this equation:
3 = -1m - 3
Let's solve this:
3 = -1m - 3
3 + 3 = -1m -3 + 3
6 = -1m
6/-1 = -1m/-1
-6 = m
or
-6 = m
Now that we have m, we can easily get the equation!
b = -3
m = -6
replacing those in the slope-intercept formula, we get:
y = mx + b
y = (-6)x + (-3)
equation: y = -6x - 3
in order to finally find the x-intercept, we find where x is when y = 0.
y = -6x - 3
make y = 0
0 = -6x - 3
0 + 3 = -6x - 3 + 3
3 = -6x
3/(-6) = -6x/(-6)
-3/6 = x
simplify
-1/2 = x
Help! I have looked at so many lessons on writing exponential functions from a graph and nothing has helped.
Answer:
y = [tex]8(-\frac{1}{2})^x[/tex]
Step-by-step explanation:
Let the equation of the exponential function is,
y = a(b)ˣ
Since the graph of this function passes through two points [tex](4, \frac{1}{2})[/tex] and (3, -1)
For the point [tex](4, \frac{1}{2})[/tex],
[tex]\frac{1}{2}=a(b)^4[/tex] ---------(1)
For second point (3, -1),
-1 = a(b)³ ---------(2)
Divide equation (2) by equation (1),
[tex]\frac{\frac{1}{2}}{-1}[/tex] = [tex]\frac{a(b)^4}{a(b)^3}[/tex]
[tex]-\frac{1}{2}=b^{(4-3)}[/tex]
[tex]-\frac{1}{2}=b[/tex]
From equation (2)
-1 = [tex]a(-\frac{1}{2})^3[/tex]
-1 = [tex]-\frac{1}{8}a[/tex]
a = 8
Therefore, equation of the exponential function will be,
y = [tex]8(-\frac{1}{2})^x[/tex]
Can someone help with this pls!! Thank u!

Answer:
9π unts²
Step-by-step explanation:
Find the diagram attached
Given the following
Radius = 6
Theta = pi/2 = 90°
Area of the sector = theta/360×πr²
Area if the sector = 90/360 × π(6)²
Area of the Sector = 1/4 × 36π

Water flows from a faucet into a bathtub at a constant rate of 2.5 gallons per minute. The bathtub initially has 5 gallon of water in it.
Complete question :
Water flows from a faucet into a bathtub at a constant rate of 2.5 gallons per minute. The bathtub initially has 5 gallon of water in it. Write a function to represent the situation.
Answer:
f(x) = 2.5x + 5
Step-by-step explanation:
A function which could be used to represent the situation is the slope - intercept function ;
The constant rate of water flow per minute could represent the slope of the function, which is the change in y per unit change in x ;
The intercept is the initial water level in the bath tub = 5 gallons
Slope intercept equation:
y = mx + c
m = slope ; c = intercept
The water in the bathtub as a function of x, number of minutes is ;
f(x) = 2.5x + 5

What does the value of the mean absolute deviation tell you about the spread of the data? HURRY PLEASE ILL GIVE 35 POINTS
Answer:
The Mean Absolute Deviation (MAD) of a set of data is the average distance between each data value and the mean. The mean absolute deviation is the "average" of the "positive distances" of each point from the mean. The larger the MAD, the greater variability there is in the data (the data is more spread out).
