y =
Answers
Answer:
y = - 5
Step-by-step explanation:
–5(y − 3) − 10 = -6y
-5y + 15 - 10 = -6y
-5y + 5 = -6y
5 = - 6y + 5y
5 = -y
-5 = y
Answer:
y = -5
Step-by-step explanation:
–5(y − 3) − 10 = –6y
First, open up the brackets.
-5y + 15 - 10 = -6y
-5y + 5 = -6y
Move y to the same side. ( when you move the numbers to the opposite side , be aware of changing the negatives and positives )
-5y + 6y = -5
y = -5

Step-by-step explanation:
Set up equation
[tex]\frac{5x}{3} +\frac{3x-2}{6} =2-3x[/tex]
Make 5x/3 and 2-3x have a denominator of 6. To do this, we multiply everything in 5x/3 by 2 and multiply everything in 2-3x by 6.
[tex]\frac{10x}{6} +\frac{3x-2}{6} =\frac{12-18x}{6}[/tex]
Add the Left fractions numerators and set them equal to the Left side.

Hi
Your question would be better with " Could you help me please ? " at the end. Quite sure your mum told you that some time in the past.
I will show you how to solve but you will do the calculus. Math is all about rules, methods and training. If you dont practice, you will never progress.
rule : you must know by heart your remarkable identities.
Here we have : ( 4x-3)² - (2x+5)² = 0
It 's of the form A² -B² = ( A+B) ( A-B)
here A is : 4x-3 and B is 2x+5
Now let's apply rule : ( 4x-3)² - (2x+5)² = ( (4x-3) +( 2x+5) ) ( (4x-3) - (2x+5)
= ( 4x-3 +2x+5 ) ( 4x-3 -2x-5 )
= ( 6x +2) ( 2x-8)
so : ( 4x-3)² - (2x+5)² = ( 6x +2) ( 2x-8)
so ( 4x-3)² - (2x+5)² = 0 means : ( 6x +2) ( 2x-8) = 0
Rule A*B = 0 if A = 0 or B = 0
A is 6x+2 and B = 2x-8
So I let you now work :
You have to solve : 6x+2 = 0
and 2x-8 = 0
Solutions of this two calculus will be the solutions of ( 4x-3)² - (2x+5)² = 0

a. 9
b. 0.56
c. 81
d. 1.78
Answers
Answer:
c
Step-by-step explanation:
Given direct variation between y and t , then the equation relating them is
y = kt ← k is the constant of variation
To find k use the condition y = 27 when t = 4 , then
27 = 4k ( divide both sides by 4 )
6.75 = k
y = 6.75t ← equation of variation
When t = 12 , then
y = 6.75 × 12 = 81

The piecewise defined function f(x) is graphed below. What is the value of f(2)?
f(2) = –2
f(2) = –1
f(2) = 4
f(2) is undefined
Answers
Answer:
f(2) = -1
Step-by-step explanation:
Looking at the graph, there appears to be two points at x = 2. However, looking more closely, we see that the point (2, 4) is empty; this means the graph goes up to this point but does not hit this point.
The point (2, -1) is filled in; this means the graph hits this point.
Step-by-step explanation:
The value of f(2) on the graph of the piecewise function is -1
How to determine the value of f(2)?From the graph of the piecewise function, we have the following highlights
When x = 2, the function has corresponding values at y = 4 and y = -1
However, the graph has an open circle at y = 4 and a closed circle at y = -1
Closed circles show inclusiveness
This means that the actual value of f(2) on the graph is -1
Hence, the value of f(2) on the graph of the piecewise function is -1

Evaluate the expression. 0.3 = -5 - (-0.4 - -0.6) Write your answer as an integer or a decimal. Do not round.
Answers
Answer:
-20
Step-by-step explanation:
Hi
The value of the expression is a decimal -17.33.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
0.3x = -5 - (-0.4 - (-0.6))
0.3x = -5 - (-0.4 + 0.6)
0.3x = -5 - 0.2
0.3x = -5.2
x = -5.2/0.3
x = -17.33
Thus,
The value of x is -17.33.

Perimeter = 2*length + 2* width
= 2(w +3) + 2w {Use distributive property}

The explanation for c: This triangle is possible since the sum of its three angles is 180 degrees.
Step-by-step explanation:
All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side;a+b > c
a+c > b
b+c > a
If this is true for all three combinations of added side lengths, then you will have a triangle.A)triangle is possible with these measurements
2+3 >4
2+4> 3
3+4>2
B)triangle is not possible with these measurements
2+3 >6
2+6> 3
3+6>2
C)triangle is possible with these measurements
90+45+45=180 degrees(sum of interior angles of a triangle is 180 degrees)
180=180
D)triangle is not possible with these measurements
90+60+60=180(sum of interior angles of a triangle is 180 degrees)
90+120 =210 degrees
sum of interior angles of the triangle is more than 180 degrees
Therefore it is not a triangle

Which of the following points lies on the line defined by y = -3x – 7?
A. (2, -1)
B.(-2, 1)
C. (-2,-1)
D. (1,8)
E. (2, 1)
Answers
=========================================================
Explanation:
If we tried the x coordinate of choice A, then,
y = -3x-7
y = -3*2-7
y = -6-7
y = -13
This shows that the point (2,-13) is on the line and not (2,-1). This rules out choice A, and also choice E.
Let's try x = -2
y = -3x-7
y = -3*(-2)-7
y = 6-7
y = -1
This shows that (-2,-1) is a point on the line, and it points us to choice C being the final answer. This rules out choice B.
If we tried x = 1, then,
y = -3x-7
y = -3*1-7
y = -3-7
y = -10
Which shows that (1,-10) is a point on this line, which rules out choice D.
The visual summary is shown below as a graph. Only point C is on the red line.
