Answer:
x = 117º
Step-by-step explanation:
Supplement to 117 is
180 - 117 = 63
The angle below line BC is marked as congruent to the 63º angle and is therefor also 63º
Therefor x is the supplement to 63º
180 - 63 = 117º
x = 117º
Which of the following is a solution to the inequality below?
–4 +
10
m
< –68
10 points
Answer:
m < - 6.4
Step-by-step explanation:
- 4 + 10m < - 68 ( add 4 to both sides )
10m < - 64 ( divide both sides by 10 )
m < - 6.4
Answer:
m can be -9
Step-by-step explanation:
-4+10m < -68
10m < -64
m < -6.4
using this statement, m can be any value less than -6.4, such as -9.

Subtraction is a mathematical operation that reflects the removal of things from a collection. The least possible height of the mont blanc is 4800 meters.
What is subtraction?Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.
Given the height of mont blanc is 4810 m correct to the nearest 10 meters. Therefore, the least possible height of the mont blanc can be written as,
Least height = 4810m - 10m = 4,800 meters
Hence, the least possible height of the mont blanc is 4800 meters.

Use the biquadratic formula =》 [tex]x=\frac{-b±\sqrt{\left(-b\right)^{2}-4 ac}}{2}[/tex]
Now,
b = 8 c = 12 a = 1Using the biquadratic formula & substituting the values....
[tex]x=\frac{-\left(-8\right)±\sqrt{\left(-8\right)^{2}-4\times 12}}{2} \\x=\frac{-\left(-8\right)±\sqrt{64-4\times 12}}{2} \\x=\frac{-\left(-8\right)±\sqrt{64-48}}{2} \\x=\frac{-\left(-8\right)±\sqrt{16}}{2} \\x=\frac{-\left(-8\right)±4}{2} \\\underline{\underline{x=\frac{8±4}{2}} }[/tex]
Now, solve when [tex]x=\frac{8+4}{2}[/tex]

Red Riding Hood drives the 432 miles to Grandmother’s house in 1 hour less than it takes the Wolf to drive the same route. Her average speed is 6 mph faster than the Wolf’s average speed. How fast does Red Riding Hood drive?
Using the relationship between velocity, distance and time, it is found that Red Riding Hood drives at 54 mph.
What is the relation between velocity, distance and time?Velocity is distance divided by time, that is:
[tex]v = \frac{d}{t}[/tex]
Red Riding Hood drives the 432 miles to Grandmother’s house in 1 hour less than it takes the Wolf to drive the same route, at a speed of 6 mph faster, hence the equations are:
[tex]v = \frac{432}{t}[/tex]
[tex]v + 6 = \frac{432}{t - 1}[/tex]
From the first equation:
[tex]t = \frac{432}{v}[/tex]
Replacing on the second equation:
[tex]v + 6 = \frac{432}{t - 1}[/tex]
[tex]v + 6 = \frac{432}{\frac{432}{v} - 1}[/tex]
[tex]v + 6 = \frac{432v}{432 - v}[/tex]
[tex]432v - v^2 + 2592 - 6v = 432v[/tex]
[tex]v^2 + 6v - 2592 = 0[/tex]
(v + 54)(v - 48) = 0.
The velocity is positive, hence:
v - 48 = 0 -> v = 48 mph.
Red Riding Hood drives 6 mph faster than Wolf, hence:
v + 6 = 48 + 6 = 54 mph.

How to write in simplified slope intercept form
Answer:
y = 4x - 3
Step-by-step explanation:
1. Pick tow points that is on the line; (1, 1) and (2, 5).
2. Find the Slope: Slope = (change in the y-values)/(change in the x-values)
Slope = (5 - 1)/(2 - 1) = 4/1 = 4
3. Use the slope and one point on the graph and substitute into y = mx + b
and solve for "b"
y = mx + b Slope = 4 point (1, 1)
1 = 4(1) + b
1 = 4 + b
1 - 4 = b
-3 = b
4. Write the equation of the line: m = 4 and b = -3
y = 4x - 3
8. Write an equation for the line in slope- intercept form.
Answer:
y equals 3x plus 4 is the answer

Step-by-step explanation:
find CP when sp=47180 loss=5%
Answer:
The cost price 49,359
Step-by-step explanation:
To find the loss, turn 5% to decimal then multiply it to the selling price
5% = 0.05
47,180 * 0.05 = 2,359
The loss is 2,359.
Now add it to the selling price to find the cost price.
47,180 + 2,359 = 49,539
For f(x) = -5x-2, evaluate f(5)
Answer:
x=5
f(x)= -5x-2
f(5)= -5(5)-2
f(5)= -25-2
f(5) = -27
Answer:
See below:
Step-by-step explanation:
So we know that [tex]f(x)=-5x-2[/tex] therefore to find out what [tex]f(5)[/tex] is we can insert/replace [tex]x[/tex] with 5 due to it being a function, after we do that, we get this:
[tex]f(5)=-5(5)-2[/tex]
Using algebra, we an find out that [tex]f(5)=-27[/tex]
