-1/4 ( 12x + 8) is less than or equal to -2x + 11 what is the solution to this inequality
Answers
Answer:
X greater or lesser than -13
Step-by-step explanation:
-1/4 (12x + 8) ≤ -2x + 11
First, distribute -1/4 into (12x + 8)
-3x - 2 ≤ -2x + 11
To solve for x, bring it to one side of the equation
-x - 2 ≤ 11
Add 2 to both sides to isolate x
-x ≤ 13
Divide each side by -1
x ≥ -13
When you divide by a negative sign with an inequality, you flip the inequality sign. So negative x is less than or equal to 13 becomes x is greater than or equal to -13.
To check this, plug in -13 for x, a number greater than -13 for x, and a number less than -13 for x. The solution will be true for a number ≥ -13, but false for a number ≤ -13

Answers
what’s the value of x and what’s the angle?
Answers
Answer:
X=9 Angle= 55
Step-by-step explanation:
The sum of all the angles of a triangle is always 180
so we add the angles
50 + 75 + (5x + 10)=180
125 +5x+ 10=180
135 +5x = 180
5x= 45
x=9
to find the angle we substitute x for 9
5(9)+10=55
Which of the following best describes the solution of the system of equations below?
Answers
Answer:
D
Step-by-step explanation:
-8x + y = -3..... (equ 1)
9x - y = 3.....(equ2)
y = 8x - 3
-y = -9x + 3(divide both sides by -1*)
hence ..y = 9x - 3
then write y = y in terms of x
which will give you 8x - 3 = 9x - 3
and solve for x which will be N/A

Answers
Answer:
Is the dilation an enlargement or reduction?
Reduction
The point of dilation is about what coordinate?
0,0
What is the scale factor?
1/3
Step-by-step explanation:
The dilation is a reduction. The point of dilation is about coordinate (0,0). The scale factor is 1/3.
What is a transformation?A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.
On a coordinate plane, the pre-image rectangle has points (0, 0), (6, 0), (6, -3), and (0, -3).
The image has points (0, 0), (2, 0), (2, -1), and (0, -1).
The required figure has been attached below which represents the dilation.
As we can see that the dilation is a reduction.
The point of dilation is about coordinate (0,0).
This result of dilating a given triangle with a scale factor is 1/3.

You ask 8 students how many letters are in their first name. One person says 6. The other 7 students say a different number of letters. Find the experimental probability of someone having 6 letters in their name based on this experiment.
Answers
Answer:
Step-by-step explanation:
Since only one out of eight said they had six letters
P(6)=1/8
The experimental probability of someone having [tex]6[/tex] letters in their name based on this experiment is [tex]\frac{1}{6}[/tex] .
What is experimental probability ?Experimental probability of an event is the ratio of the number of outcomes in which a specified event occurs to the total number of trials, not in a theoretical sample space but in an actual experiment.
[tex]Experimental \ probability = \frac{Total \ number \ of \ outcomes}{Number \ of \ favorable \ outcomes}[/tex]
We have,
Total number of students [tex]=8[/tex]
Person having [tex]6[/tex] letters in the name [tex]=1[/tex]
Other [tex]7[/tex] person says different number of letters.
So,
Experimental probability of someone having [tex]6[/tex] letters in their name is determined ;
[tex]Experimental \ probability = \frac{Total \ number \ of \ outcomes}{Number \ of \ favorable \ outcomes}[/tex]
[tex]=\frac{1}{6}[/tex]
So, Experimental probability of someone having [tex]6[/tex] letters in their name is [tex]\frac{1}{6}[/tex] , which is determined using the above given formula.
Hence, we can say that the experimental probability of someone having [tex]6[/tex] letters in their name based on this experiment is [tex]\frac{1}{6}[/tex] .

Answer:
C. She did not keep the order of the points the same in the numerator and the denominator.
Step-by-step explanation: Hope this helps
The correct slope should look like: 1-17/14-18
If you do 1-17 for the numerator then 14-18 must be the denominator (the slope is 4: -16/-4 = 4)
The equation to find the slope of a line is (y2-y1)/(x2-x1). (x1,y1) is the first coordinate point, (x2, y2) is the other. It does not matter which coordinate point you use first, as long as you remain consistent.
