Select the values that make the inequality true
Inequality shows a relationship between two numbers or two expressions.
The equivalent inequality of [tex]\frac{k}{-2}[/tex] ≤ 4 is k ≤ -8.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal =
Greater than and equal=
Example:
2 < 4
2x < 10
3x > 18
We have,
[tex]\frac{k}{-2}[/tex] ≤ 4
We will make an inequality in terms of k on one side.
Multiply -2 on both sides.
k ≤ -2 x 4
k ≤ -8
Thus,
The equivalent inequality of [tex]\frac{k}{-2}[/tex] ≤ 4 is k ≤ -8.

7th grade math pls help
Answer:
C, but not fully sure
Step-by-step explanation:
Use the Distributive Property to solve the problem. [Example: 4(6+3) = 4(6)+4(3) = 24 + 12 = 36] 9(8 + 4)
(sorry for spamming these questions, its part of an assignment i HAVE to do well on to raise my horrible math grade)
please let me know if you need help on anything else.
4(6+3)=4(6)+4(3)=24+12=36.
multiply 4(6) and 4(3).
4x6=24 4x3=12
24+12=24+12=24+12=36
24+12=36

Answer:
2x = 6
Step-by-step explanation:
Simplify the following algebraic expressions.
- 6x + 5 + 12x -6
2(x - 9) + 6(-x + 2) + 4x
3x2 + 12 + 9x - 20 + 6x2 - x
(x + 2)(x + 4) + (x + 5)(-x - 1)
1.2(x - 9) - 2.3(x + 4)
(x2y)(xy2)
(-x2y2)(xy2)
Solution
Group like terms and simplify.
- 6x + 5 + 12x -6 = (- 6x + 12x) + (5 - 6)
= 6x - 1
Expand brackets.
2(x - 9) + 6(-x + 2) + 4x = 2x - 18 - 6x + 12 + 4x
Group like terms and simplify.
= (2x - 6x + 4x) + (- 18 + 12) = - 6
Group like terms and simplify.
3x2 + 12 + 9x - 20 + 6x2 - x
= (3x2 + 6x2) + (9x - x) + (12 - 20)
= 9x2 + 8x - 8
Expand brackets.
(x + 2)(x + 4) + (x + 5)(- x - 1)
= x2 + 4x + 2x + 8 - x2 - x - 5x - 5
Group like terms.
= (x2 - x2) + (4x + 2x - x - 5x) + (8 - 5)
= 3
Expand and group.
1.2(x - 9) - 2.3(x + 4)
= 1.2x - 10.8 - 2.3x - 9.2
= -1.1x - 20
Rewrite as follows.
(x2y)(xy2) = (x2 x)(y y2)
Use rules of exponential.
= x3 y3
Rewrite expression as follows.
(-x2y2)(xy2) = -(x2 x)( y2 y2)
Use rules of exponential.
= - x3 y4
Simplify the expressions.
(a b2)(a3 b) / (a2 b3)
(21 x5) / (3 x4)
(6 x4)(4 y2) / [ (3 x2)(16 y) ]
(4x - 12) / 4
(-5x - 10) / (x + 2)
(x2 - 4x - 12) / (x2 - 2 x - 24)
Solution
Use rules of exponential to simplify the numerator first.
(a b2)(a3 b) / (a2 b3) = (a4 b3) / (a2 b3)
Rewrite as follows.
(a4 / a2) (b3 / b3)
Use rule of quotient of exponentials to simplify.
= a2
Rewrite as follows.
(21 x5) / (3 x4) = (21 / 3)(x5 / x4)
Simplify.
= 7 x
(6 x4)(4 y2) / [ (3 x2)(16 y) ]
Multiply terms in numerator and denominator and simplify.
(6 x4)(4 y2) / [ (3 x2)(16 y) ] = (24 x4 y2) / (48 x2 y)
Rewrite as follows.
= (24 / 48)(x4 / x2)(y2 / y)
Simplify.
= (1 / 2) x2 y
Factor 4 out in the numerator.
(4x - 12) / 4 = 4(x - 3) / 4
Simplify.
= x - 3
Factor -5 out in the numerator.
(-5x - 10) / (x + 2) = - 5 (x + 2) / (x + 2)
Simplify.
= - 5
Factor numerator and denominator as follows.
(x2 - 4x - 12) / (x2 - 2x - 24) = [(x - 6)(x + 2)] / [(x - 6)(x + 4)]
Simplify.
= (x + 2) / (x + 4) , for all x not equal to 6
Solve for x the following linear equations.
2x = 6
Prove the divisibility of the following problems: (This is for RSM)
25^9+5^17 is divisible by 30
11^9-11^8+11^7 is divisible by 3 and 37
Will mark brainliest!
It should be noted that since 25⁹ + 5^¹⁷ is divisible by 2, 3, and 5, it is divisible by 30.
How to explain the divisionTo prove that 25⁹ + 5¹⁷ is divisible by 30, we can observe that 30 is a composite number with prime factors 2, 3, and 5. Thus, we need to show that 25⁹ + 5¹⁷ is divisible by 2, 3, and 5.
25⁹ ≡ (-1)⁹ ≡ -1 (mod 3)
5¹⁷ ≡ 2¹⁷ ≡ 2² × (2³)⁵ ≡ 4 × (-1)⁵ ≡ -4 ≡ 2 (mod 3)
Since 25⁹ + 5¹⁷ is divisible by 2, 3, and 5, it is divisible by 30.

Answer:
Statement Two: The y-intercept of Function A is less than the y-intercept of Function B
Step-by-step explanation:
The y-intercept of Function A is -1
To calculate the y-intercept of Function B we first need to determine the slope.
The formula for slope is [tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex] [tex]\frac{4-2}{9-3} =\frac{2}{6} =\frac{1}{3}[/tex]
Now that we have the slope (1/3 x) we can find the y-intercept
[tex]b=y-mx[/tex]
[tex]b=0-(\frac{1}{3})(-3)[/tex]
[tex]b=1[/tex]
1 > -1, so Statement Two is true

Answer:
x = -12.5
Step-by-step explanation:
your goal is to get x alone so
-2x - 10 = 15
(add ten to both sides)
-2x = 25
(divide -2 to both sides)
x = -12.5
remember that whatever u do to one side of the equation, you have to do to the other so they even out!
