Answer:
Step-by-step explanation:
A line that is perpendicular to a reference line will have a slope that is the negative inverse of the reference line.
In this case, the reference line is y = -x - 1. It has a slope of -1. The negative inverse of this would be -(1/-1) = 1.
We can then write:
y = mx + b
y = 1x + b
To find b, enter the one given point that lines on the line, (-4,2).
y = 1x + b
y = 1x + b for (-4,2)
2 = 1(-4) + b
b = 6
The equation becomes y = x + 6
See attached.
Step-by-step explanation:
Simply Equation 1
R. H. S
6x^2 -x +3-2x^2-8
==> 6x^2-2x^2 -x +3-8
==> 4x^2-x-5 .....(1)
Simply equation 2
L. H. S
4x^2+2x-5-3x
==> 4x^2 +2x-3x-5
==> 4x^2-x-5 ....(2)
Since here, RHS = LHS
both eqn (1) = eqn(2)
hence they are equal.
Hello, and welcome to Brainly!
To answer this question, you must first isolate the given variable, a. Treat the < sign as an equal sign, in that what you do to one side, you do to the other.
Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:
Parenthesis
Exponents (& roots)
Multiplications
Divisions
Additions
Subtractions

First, subtract 8a and add 6 to both side inequality.
a (-8a) - 6 (+6) < 15 (+6) + 8a (-8a)
a - 8a < 15 + 6
-7a < 21
Next, isolate the variable, a, by dividing -7 from both sides of the equation. Note that, when dividing or multiplying by a negative number, you must flip the sign:
(-7a)/-7 < (21)/-7
a < 21/-7
a > -3
a > -3 is your answer.

Answer:
To solve for e, divide 10 from each side.. 1 divided by 10 e=0.1
Answer:
$67.90
Step-by-step explanation:
One song = 0.97
You buy 70 songs
0.97 * 70 = 67.9
Since it deals with money you have two decimal places and add the $
So it will come to $67.90
