Step 1: Define
-6 = n/2 - 10
Step 2: Solve for n
Add 10 to both sides: 4 = n/2Multiply 2 on both sides: 8 = nRewrite: n = 8Step 3: Check
Plug in n into the original equation to verify it's a solution.
Substitute in n: -6 = 8/2 - 10Divide: -6 = 4 - 10Subtract: -6 = -6Here we see that -6 does indeed equal -6.
∴ n = 8 is the solution to the equation.
Please help and Imma be postin these all night I literally suck at algebra two so just check my profile if your good at math :)
Answer:
The range of the equation is y ≥ 9 ⇒ C
Step-by-step explanation:
The quadratic equation y = ax² + bx + c, represents by a parabola of vertex (h, k), where h = [tex]\frac{-b}{2a}[/tex] and k is the value of y at x = h
The range of the quadratic if it has a minimum vertex is y ≥ k, and y ≤ k if it has a maximum vertexThe parabola has a minimum vertex if the value of a is positive and a maximum vertex if the value of a is negative∵ The equation is y = x² + 9
→ Compare it with the form above to find a and b
∴ a = 1 and b = 0
∵ a is a positive number
∴ The parabola has a minimum vertex
→ By using the 1st rule above
∴ The range is y ≥ k
→ Use the rule of h above to find it
∵ h = [tex]\frac{-(0)}{2(1)}[/tex] = [tex]\frac{0}{2}[/tex]
∴ h = 0
→ To find k substitute x by the value of h and y by k
∵ k = (0)² + 9
∴ k = 0 + 9
∴ k = 9
∴ The range of the equation is y ≥ 9
can someone help me solve x
Answer:6
Step-by-step explanation:solve the equation, you know that it equals 90 because the angle is 90
so 16x-6=90
+6 both sides
16x=96
divided by 16 both sides to isolate x
x=6
Solve
7x — 2 = 5x + 14

Answer:
[tex]x=29[/tex]
Step-by-step explanation:
The two pair of angles that are given values are supplementary, meaning they add up to [tex]180^{\circ}[/tex]. Therefore, we have the following equation:
[tex]2x-10+4x+16=180,\\6x+6=180,\\6x=174,\\x=\fbox{$29$}[/tex].
Answer:
[tex]\huge{ x=29° }[/tex]
Step-by-step explanation:
Here,
The two lines are parallel.
So,The angle (2x-10) and (4x+16) are corresponding. because these angles are the consecutive interior angles.
we know that,
Sum of corresponding angle =180°
According to the question,
[tex]\bold{(2x-10)+(4x+16)=180 }[/tex]
[tex]\bold{2x-10+4x+16=180 }[/tex]
[tex]\bold{ 6x+6=180 }[/tex]
[tex]\bold{6x=180-6 }[/tex]
[tex]\bold{ 6x=174 }[/tex]
[tex]\bold{ x=\dfrac{174}{6} }[/tex]
[tex]\bold{ x=29 }[/tex]
so,
value of x=29°

The points in the table lie on a line. Find the slope of the line.
Answer:
slope: [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
If we were to plot the first pair on a graph it would be (-2,3) and the next pair of points plotted would be (0,4). The intercepts are [tex]x^{1},x^{2}[/tex] and [tex]y^{1}, y^{2}[/tex]. To find the slope of a line using pairs of plotted points, you need to use the slope formula [tex]\frac{rise}{run}[/tex] to solve this.
- write your formula
[tex]\frac{rise}{run} : m=\frac{y^{2}-y^{1} }{x^{2}-x^{1} }[/tex]
- plug in your numbers
[tex]m=\frac{4-3}{0-(-2)}[/tex]
- solve
[tex]m=\frac{1}{2}[/tex]

The lifetime for a certain type of tre has been shown to be five years the mean) with a standard deviation of 6 months. In a normal distribution, what percentage of these tires will
last more than six years (more than two standard deviations above the mean)?
Answer:
2.28%
Step-by-step explanation:
mean = 5 years = 60 months
standard deviation = 6 months
X = number of years the tires will last
P = probability of ...
z = z-score
6 years = 72 months
z = (# of months - mean) / standard deviation
z = (72 - 60)/6
z = 12/6
z = 2
P(X > 72) = 1 - P(X < 72)
= 1 - P(z < 2)
(using a Standard Normal Probabilities Table we can see that P(z < 2) = .9772)
So:
= 1 - .9772
= 0.0228 OR 2.28%
15 POINTS A 4-inch length is represented as 1/8 on a scale drawing. What is the scale used on the drawing?
1 foot=3/4 inch
1 foot =3/8 inch
1 foot= 1/2 inch
1 foot = 1/4 inch
Please explain im not good at scales and models.
9514 1404 393
Answer:
(b) 1 foot = 3/8 inch
Step-by-step explanation:
The given ratio is ...
actual : scale = 4" : 1/8"
You know that 1 foot = 12 in = 3×4 in, so you can multiply the above ratio by 3 to see what it is for 1 foot.
actual : scale = 3×4" : 3×1/8"
= 12" : 3/8"
= 1 foot : 3/8 in
______
Alternate approach
Essentially, we're saying that the ratios between actual measures and those on a scaled drawing or model form a proportion.
scale / actual = (1/8")/(4 in) = ??/(12 in)
Multiplying by 12 in, we get ...
?? = (12 in)(1/8")/(4 in) = 3×1/8"
?? = 3/8"
__
More detail
Notice that this only works when the units in the ratio (12 in)/(4 in) cancel to give a pure number 12/4 = 3.
If we had put 1 foot in the proportion, then we would end up with ?? being expressed in feet, not inches:
(1/8")/(4") = ??/(1 ft)
?? = (1 ft)(1/8")/(4") = (1 ft)(1/32) = 1/32 ft
Then, to find the answer to the question, we would have to find out how many inches is 1/32 ft.
1/32 ft = (1/32)(12 in) = 12/32 in = 3/8 in
__
End comment
For best results, the units in corresponding parts of a proportion should be the same.
Solve for x
Is a short response
Answer:
x = 1/4
Step-by-step explanation:
[tex]log_{x}[/tex] 16 = 2 can be written as [tex]16^{x}[/tex] = 2
([tex]2^{4}[/tex])^x = 2^1
if bases are the same we can create this equation: 4x = 1
x = 1/4

These dot plots show lengths (in feet) from a sample of crocodiles and alligators.
Compare the outliers and interquartile ranges (IQRs) for the data sets. Which
statement is true?
A. Alligators have a smaller IQR because there were some very long
alligators (high outliers).
B. Crocodiles have a greater IQR because most of the crocodiles
were about the same length.
C. Alligators have a smaller IQR because there were some very short
alligators (low outliers).
D. Alligators have a greater IQR because there were some very long
alligators (high outliers).
Alligators have a greater IQR because there were some very long alligators (high outliers)
D: Alligators have a greater IQR because there were some very long alligators (high outliers)
How to find outliers and the interquartile range?Use the interquartile rule to find outliers and calculate the interquartile range of data.
Multiply the interquartile range (IQR) by 1.5 (a constant used to identify outliers). 44 Adds 1.5x (IQR) to the 4th interquartile range. Numbers larger than this are suspected of being outliers.
Subtract 1.5x (IQR) from the first interquartile range.
If you subtract 1.5xIQR from the first quartile, data values smaller than this number are considered outliers. If you add 1.5 x IQR to the third interquartile, data values larger than this number are considered outliers.
