Answer:
x=4 or x=-10
Step-by-step explanation:
x² + 6x = 40
x² + 6x - 40 = 40 - 40
x² + 6x - 40 = 0
Use quadratic formula:[tex]\frac{b-+\sqrt{b^{2} -4ac} }{2a}[/tex]
a=1 , b=6 , c= -40
[tex]\frac{-(6)-+\sqrt{6^{2} -4.1.(-40)} }{2.1}[/tex]
[tex]\frac{-(6)-+\sqrt{196} }{2.1}[/tex]
x=4 or x=-10

Solve for x.
Your answer must be simplified.
-3
Answer:
x > 7
Step-by-step explanation:
-3 < x - 10
Subtract x from both sides.
-x - 3 < -10
Add 3 to both sides.
-x < -7
Divide both sides by -1. Remember that when you multiply or divide both sides of an inequality by a negative number, the inequality sign changes direction.
x > 7
16.8=2.4e
what does the E equal
16.8 = 2.4 e
=> e = 16.8/2.4
=> e = 168/24
=> e = 7
Hence, E equal to 7
Answer:
e = 7
Step-by-step explanation:
2.4e is the same as [tex]2.4*e[/tex], so you simply undo the equation.
[tex]16.8=2.4*e[/tex]
divide by 2.4 on both sides to isolate the variable.
[tex]16.8/2.4 = (2.4 *e)/2.4[/tex]
[tex]7 = e[/tex]

What is distance between point X and point Y?
StartRoot 11 EndRoot
StartRoot 22 EndRoot
StartRoot 61 EndRoot
StartRoot 72 EndRoot
Answer:
The answer is 61:)
Step-by-step explanation:
The concept distance formula is used here to determine the distance between two points. The distance between two points is the length of the line joining the two points. The distance between point X and point Y is 4√2 units.
What is distance formula?In analytical geometry, the distance formula is used to find the distance measure between two lines. The distance between two points of the xy-plane can be found using the distance formula.
The distance between two points is given as:
d = √(x₂ - x₁)² + (y₂ - y₁)²
d = √(-1 + 5)² + (3 - 7)²
d = √(4)² + (-4)² = √16 + 16
d = 4√2 units
Thus the distance between two points X(-5,7) and Y(-1,3) is 4√2 units.

The data set shows the numbers of hours students study the week before a test. Find and interpret the mean absolute deviation of the data. Write your answer as a decimal. 1, 1, 1, 3, 4, 5, 6, 7, 8, 10 The data values differ from the mean by an average of hours.
Answer:
4.6
Step-by-step explanation:
to find the mean, you add up all given numbers and divide by how many numbers is given. so if there are five numbers, you divide the sum of all of the numbers by five.

Answer:
11.65 km / day
Step-by-step explanation:
We can calculate the amount of daily kilometer in the following way
First day: 2 * 6 = 12 km
Second day: 1.5 * 6 = 9 km
Third day: 1.333 * 6 = 8 km
Fourth day: 2.4 * 6 = 14.4 km
Sixth day: 1.666 * 6 = 10 km
on Saturday: 2.75 * 6 = 16.5 km
the average per day
(12 + 9 + 8 + 14.4 + 10 +16.5) / 6 = 11.65
11.65 km/day

Which equation represents circle C
options are in the picture
Answer: (x+4)^2 + (y-1)^2 = 162
Step-by-step explanation:
Equation of Circle : (x – h)^2 + (y – k)^2 = r^2
(h, k) is the center of the circle, r is the radius
The center is (-4, 1), plug it in to get:
(x+4)^2 + (y-1)^2 = r^2
To find the radius we can use the distance formula to find the distance between C and P:
Distance Formula: d = [tex]\sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}[/tex]
Plug in C: (-4, 1) and P:(5, -8) to get [tex]\sqrt{162}[/tex]
So, the equation is:
(x+4)^2 + (y-1)^2 = [tex]\sqrt{162} ^{2}[/tex]
(x+4)^2 + (y-1)^2 = 162
