Answer:
[tex]y = \frac{-1}{9}[/tex]
Step-by-step explanation:
[tex]7y + 4 = 3 - 2y[/tex]
add [tex]2y[/tex] to both sides
[tex]7y + 4 + 2y = 3 -2y + 2y \\9y + 4 = 3[/tex]
add [tex]-4[/tex] to both sides
[tex]9y + 4 -4 = 3 - 4 \\9y = -1[/tex]
divide both sides by [tex]9[/tex]
[tex]\frac{9y}{9} = \frac{-1}{9} \\[/tex]
[tex]y = \frac{-1}{9}[/tex]
The solution to the equation 7y + 4 = 3 - 2y is y = -1/9.
Here, we have,
To solve for y in the equation 7y + 4 = 3 - 2y, we can follow these steps:
Step 1: Combine like terms on both sides of the equation:
7y + 2y = 3 - 4.
Simplifying:
9y = -1.
Step 2: Divide both sides of the equation by 9 to isolate the variable y:
(9y)/9 = (-1)/9.
Simplifying:
y = -1/9.
Therefore, the solution to the equation 7y + 4 = 3 - 2y is y = -1/9.

x =
Hey there!
[tex]Answer:\boxed{x=6}[/tex]
[tex]Explanation:[/tex]
[tex]8x+0.2=48.2[/tex]
Let's start with subtracting 0.2 from both sides of the equation.
[tex]8x+0.2-0.2=48.2-0.2\\8x=48[/tex]
In our second/last step, we will divide both sides by 8.

Determine whether the triangle with vertices at the points below is scalene, isosceles, or equilateral:
(3, 4), (8, -1), (10,3)
Answer:
Step-by-step explanation:
This is a isosceles triangle, An isosceles triangle is a triangle with (at least) two equal sides. In the figure above, the two equal sides have length and the remaining side has length.
A scalene triangle is a triangle in which all three sides have different lengths. Also the angles of a scalene triangle have different measures.
In geometry, an equilateral triangle is a triangle in which all three sides have the same length. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.
6(2t+9)<12t-1 what is the answer
Answer:
no solutions
Step-by-step explanation:
The inequality: 6(2t+9)<12t-1
First, use distributive property
12t+54<12t-1
Now, add 1 on both sides
12t+55<12t
Subtract 12t on both sides
55<0

Marianne wanted to know students' opinion on the new schedule at school. She survey's the first
30 students who come into her class. What type of sampling is this?
I think it is a Convience Sampling.
The type of sampling that Marianne is using is convenience sampling.
What is convenience sampling?Convenience sampling is a non-probability sampling method where individuals are selected based on their availability and willingness to participate in the study.
Here, Marianne surveyed the first 30 students who came into her class, which means that she selected the participants based on their convenience of being there at that particular time.
Convenience sampling is not a random sampling method, and it can introduce bias into the results because the sample may not be representative of the population of interest.
In this case, the sample of students may not represent the entire student population at the school, and the results may not be generalizable to other students.
Thus, the type of sampling that Marianne is using is convenience sampling.

what is the solution to this inequality: -4(3x-5)<2(3x+4)
Answer:
x > 2/3
Step-by-step explanation:
-4(3x - 5) < 2(3x + 4)
Divide both sides by 2.
-2(3x - 5) < 3x + 4
Distribute on the left side.
-6x + 10 < 3x + 4
Subtract 3x from both sides.
-9x + 10 < 4
Subtract 10 from both sides.
-9x < - 6
Divide both sides by -9. Remember that when you divide both sides of an inequality by a negative number, the inequality sign changes direction.
x > (-6)/(-9)
x > 6/9
x > 2/3
