5a+8+(-2a)=-7
I need help with this question especially because of the parenthesis
Answers
Answer:
5a+8+(-2a)=-7
5a+8-2a=-7
5a-2a=-7-8
3a=-15
3a/3=-15/3
a=-5
Answer:
a = -5
Step-by-step explanation:
Simplify both sides:
5a + 8 + (-2a) = -7
(5a + -2a) + 8 = -7
3a + 8 = -7
Start solving for a by subtracting 8 from both sides
3a+8-8 = -7 - 8
3a = -15
Next, divide both sides by 3
3a/3 = 1
-15/3 = -5
a = -5

The equation of a line is y = -3x – 2. What are the slope and the y-intercept of the line?
A.
slope = -3 and y-intercept = 2
B.
slope = 3 and y-intercept = -2
C.
slope = 3 and y-intercept = 2
D.
slope = -3 and y-intercept = -2
Answers
The slope of the line is - 3 and the y - intercept of the line is - 2.
What is Equation of line?The equation of line passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;
y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The equation of line is,
⇒ y = - 3x - 2
We know that;
The slope - intercept form of the equation of line is,
⇒ y = mx + b
Where, m is slope and b is y - intercept.
So, By comparing we get;
The slope (m) of the line = - 3
And, the y - intercept of the line = - 2.

Which diagram provides a counter example to the statement below?
“Supplementary angles are never congruent.”
Answers
Two or more angles are supplementary if and only if they can add up to [tex]180^{o}[/tex]. Thus, the appropriate option would be C.
Supplementary angles are angles that add up to the value of angle on a straight line i.e [tex]180^{o}[/tex].
Congruent property of angles implies that they have equal value.
Thus, the given statement that: “Supplementary angles are never congruent”, implies that they can not be equal in value. Thus the contrary to the statement would be: “Supplementary angles are sometimes congruent.”
Considering the figures given in the question, the counter example to the given statement is the figure in option C. [tex]180^{o}[/tex]. Because angle 1 and 2 are approximately equal.

What is an equation that goes through (12, 5); m = -3
Please help
Answers
Answer:
Step-by-step explanation:
Use this formula:
y - y1 = m ( x - x1 )
We are told m = -3 and given the point (12 , 5) ---- > so x1 = 12 and y1= 5
Put these values into the formula above and you get:
y - y1 = m ( x - x1 )
y - 5 = -3 ( x - 12 )
y - 5 = -3x + 36
y = -3x + 36 + 5
y = -3x + 41

As the exponent on the base 10 increases, does
the standard notation number get larger or
smaller in value? Explain why.
Help Please
Answers
Answer:
Since the exponent on 10 is positive, I know they are looking for a LARGE number, so I'll need to move the decimal point to the right, in order to make the number LARGER. Since the exponent on 10 is "12", I'll need to move the decimal point twelve places over.
First, I'll move the decimal point twelve places over. I make little loops when I count off the places, to keep track:
3.6 _ _ _ _ _ _ _ _ _ _ _ .
Then I fill in the loops with zeroes:
3.600000000000.
In other words, the number is 3,600,000,000,000, or 3.6 trillion
Step-by-step explanation:
[tex]10^{x}[/tex]
Where:
10 = Base 10
x = Exponent
When the exponent on the base 10 increases, the standard notation number gets larger in value. This is because the exponent is directly proportional to the size of the standard notation of the number.For example:
[tex]10^{2} = 100[/tex]
[tex]10^{3} = 1000[/tex]
[tex]10^{8} = 100000000[/tex]
