x^2+6x≤-5 with an explanation pls
Answer:
−5≤x≤−1
Step-by-step explanation:hope that helps :)))
x2+6x=−5
x2+6x−(−5)=−5−(−5)(Subtract -5 from both sides)
x2+6x+5=0
(x+1)(x+5)=0(Factor left side of the equation)
x+1=0 or x+5=0(Set factors equal to 0)
x=−1 or x=−5

What is the value of x
Answer:
98 degrees
Step-by-step explanation:
First calculate the entire triangles angles:
180 - 53 - 45 = final angle of triangle
82 = final angle of triangle
Using the straight line rule for angles, x and the inner angle must equal to 180 degrees:
180 - 82 = x
98 = x
Angle x is 98 degrees.

Solve the system of equations using substitution.
- 4x + 4y= 8
y= -2x – 10
-
O (4, -18)
O (12, -34)
o(-4,-2)
O (-2,-6)
Answer:
(- 4, - 2 )
Step-by-step explanation:
Given the 2 equations
- 4x + 4y = 8 → (1)
y = - 2x - 10 → (2)
Substitute y = - 2x - 10 into (1)
- 4x + 4(- 2x - 10) = 8 ← distribute and simplify left side
- 4x - 8x - 40 = 8
- 12x - 40 = 8 ( add 40 to both sides )
- 12x = 48 ( divide both sides by - 12 )
x = - 4
Substitute x = - 4 into (2) for corresponding value of y
y = - 2(- 4) - 10 = 8 - 10 = - 2
Solution is (- 4, - 2 )

- The value of y varies directly with x. If x= 4,
then y= 32. What is the value of x when y= 176?
Answer: Wouldn't that make it x=44
Step-by-step explanation:
I just divided 176 by 4 because it said the value of y varies directly with x. So just used the rule they used i guess.

What is x equal to? And what is the scale factor?
Answer:
1. 225 km
2. 95 km
3. 412.5 km
Step-by-step explanation:
For this one, it is saying that for every 2 cm, that is 50 km. So if you look at 9 cm, you can divide that by 2 cm to get 4.5 cm, this is what you can multiply by 50 km to get 225. Or you can look at it this way, for every 1 cm, the actual distance is 25 km. Then you can multiply each value by 25 to get your answer. Whichever one works for you.
Kinsley's age is 7 years less than twice Jacob's age. If Kinsley is 13 years old, how old is Jacob? Choose the answer below that is a viable solution to this problem.

Answer:
10x2= 20 -7 =13 :answer is 10.
Step-by-step explanation:
Answer:
10
Step-by-step explanation:
Kinsey is 7 years less than twice Jacob's age. Let's call Jacob's age x. IF we call Jacob's age x, our equation can be 2x-7 = 13
2x - 7 = 13
2x = 20
x=10
Jacob is 10 years old.

-8(s+4) = -60
What is the value of s?
Answer:
s = 3.5
Step-by-step explanation:
Lets begin by distributing -8 into the two values in the paranthesis, s and +4. By doing this, we get -8s -32 = -60
We can now take that -32 and bring it to the right side of the equation, making it now -8s = +32 -60
After simplyfing, we now have -8s = -28. Dividing -28 by -8 , we get positive 3.5.

What is the slope of the line that passes through the points M (-3,5) and N (1,8)
Answer:
m=3/4
Step-by-step explanation:
See the attached above.
Hope it helps :)
The slope of line passing through M (-3,5) & N (1,8) will be 3/4.
We have been given a line passing through points M (-3,5) & N (1,8) .
We have to find out what will be the slope of the line ?
What is the formula for slope of a line ?
Slope of line is given by , m = (y2-y1) / (x2-x1).
Given that line is passing through points M (x1 , y1) and N (x2,y2) or M (-3,5) & N (1,8).
here , x1 = -3 , y1 = 5 , x2= 1 . y2 = 8
The slope (m) of line will be ;
∵ m = ( y2-y1) / (x2-x1)
m = ( 8-5) / (1- (-3))
m = 3 / 4

Consider a geometric sequence with a first term of 4 and a fourth term of -2.916.
a) Find the common ratio of this sequence.
b) Find the sum to infinity of this sequence.
Answer:
a) Find the common ratio of this sequence.
Answer: -0.82
b) Find the sum to infinity of this sequence.
Answer: 2.2
Step-by-step explanation:
nth term in geometric series is given by [tex]4\ th \ term = ar^n-1\\-2.196 = 4r^{4-1} \\-2.196/4 = r^{3} \\r = \sqrt[3]{0.549} \\r = 0.82[/tex]
where
a is the first term
r is the common ratio and
n is the nth term
_________________________________
given
a = 4
4th term = -2.196
let
common ratio of this sequence. be r
[tex]4\ th \ term = ar^n-1\\-2.196 = 4r^{4-1} \\-2.196/4 = r^{3} \\r = \sqrt[3]{-0.549} \\r = -0.82[/tex]
a) Find the common ratio of this sequence.
answer: -0.82
sum of infinity of geometric sequence is given by = a/(1-r)
thus,
sum to infinity of this sequence = 4/(1-(-0.82) = 4/1.82 = 2.2
