Using point P, which point would form a line parallel to line AB?
(-6,4)
(3,2)
(1,1)
(-2,3)
Answers
Answer:
(3,2)
Step-by-step explanation:
The equation of the line graphed is
y = 2/3x + 2
Parallel lines have the same slope.
y = mx + b
y = 2/3x + 0 P tells me that the y-intercept is 0
y = 2/3 x Which point would make this true?
Point (3,2) We plug in 3 for x and 2 for y
2 = 2/3(3)
2 = 2 This is a true statement, so the point (3,2) is on the line.

Find the y intercept (if there is one) put your answer as a ordered pair.
(-2,6) (1,6)
Answers
The y-intercept of the line that passes through points (-2,6) and (1,6) in an ordered pair is ( 0,6 ).
What is the y-intercept of the line that passes through the given points?The formula for equation of line is expressed as;
y = mx + b
Where m is slope and b is y-intercept.
The slope of a line is expressed as change in y over change in x.
Slope m = (y₂-y₁)/(x₂-x₁)
Given the data in the question;
Point A ( -2,6 )
x₁ = -2y₁ = 6Point B ( 1, 6 )
x₂ = 1y₂ = 6First, we determine the slope of the line.
Slope m = (y₂-y₁)/(x₂-x₁)
Slope m = ( 6 - 6 )/( 1 - ( -2) )
Slope m = ( 0 )/( 1 + 2) )
Slope m = ( 0 )/3
Slope m = 0
Now, we can determine the y-intercept b, using the slope and coordinates of 1 point.
y = mx + b
6 = (0)(1) + b
Solve for b
6 = 0 + b
b = 6
Therefore, the coordinates of the y-intercept is ( 0,6 ).

what does this mean 3|-3| the whole |-3| thing I'm confused please help
Answers
|-3| means "the absolute value of 3", which is a way of saying how far away from zero the number -3 is on the number line.
The definition of absolute value goes like this:
[tex]|x| = \begin{cases} x & \text{if } x \ge 0 \\ -x & \text{if } x < 0 \end{cases}[/tex]
In other words, if the number [tex]x[/tex] inside the absolute value bars is already positive or zero, we leave it alone. If instead [tex]x[/tex] is negative, we multiply it by -1 to recover the positive version of that number.
Since -3 is negative, it follows that |-3| = -(-3) = 3. So the expression 3 |-3| is equivalent to 3 • 3 = 3² = 9.

Describe and correct the error in evaluating the expression.
9 + 2 x 3 = 11 x 3 = 33
How would you write this problem with the multiplication first?
Answers
The error in the solution is adding 9 and 2 before the multiplication and the new expression is (2 x 3) + 9
The description of the error?The equation and the steps are given as
9 + 2 x 3 = 11 x 3 = 33
The above solution is incorrect
This is so because the product has a higher order of precedence
So, it must be evaluated first
So, the correct solution is
9 + 2 x 3 = 9 + 6 = 15
To rewrite the expression such that the product is done first, we introduce the use of brackets
So, we have
9 + (2 x 3)
This gives
(2 x 3) + 9
Hence, the result of the products is (2 x 3) + 9

Olivia and Camille went clothes shopping. Camille spent $14 less than three
times what Olivia spent. In total, they spent $54. How much did each girl
spend?
Answers
By solving a system of equations we can see that Olivia spent $14 and Camiller spent $37.
How much did each girl spend?Let's define two variables:
x = Amount that Olivia spends.y = Amount that Camille spendsWe know that " Camille spent $14 less than three times what Olivia spent" so we can write:
y = 3*x - 14
And "In total, they spent $54"
x + y = 54
Then we have a system of equations:
y = 3*x - 14
x + y = 54
Replacing the first equation into the second one, we get:
x + 3x- 14 = 54
4x - 14 = 54
4x = 54 + 14
4x = 68
x = 68/4 = 17
Now that we know the value of x, we can try to find the value of y.
y = 3x - 14 = 3*17 - 14 = 37
So Olivia spent $14 and Camiller spent $37.

Answers
Answer:
a₂ = 12.5 m/s²
Step-by-step explanation:
Applying the 2º Newton's Law:
∑F = m * a
F₁ = m₁ * a₁
F₁ = m₁ * 12.5
F₁ = 12.5m₁
F₂ = m₂ * a₂
2F₁ = 2m₁ * a₂
a₂ = F₁ / m₁

Answers
The number 25×10 to the power of -3 written in the standard form is 2.5×10⁻⁴.
What is meant by the term scientific notations?Scientific notation is a way of displaying very large or extremely small numbers in a more simplified format. We know that whole numbers could be extended indefinitely, but such large numbers cannot be written on a sheet of paper. The scientific notation allows us to represent very large or very small numbers by multiplying single-digit numbers by 10 raised to a power of a respective exponent. If the number is so very large, the exponent is positive; otherwise, it is negative. For a better understanding, learn power and exponents.The given number is;
25×10 to the power of -3
This can be written as;
= 25×10⁻³
Now, as per the standard form, the number should contain only one digit to the left of decimal.
Thus, shifting one decimal to the left of the 5 and converting the power by adding one to the current power,.
The number becomes;
= 2.5×10⁻⁴.
Thus, the number written in the standard form is 2.5×10⁻⁴.

solution a is 2% alcohol and solution b is 5% alcohol. she uses 800 milliliters of solution A how many milliliters of solution b does she use if the resulting mixture is a 3% alcohol situation
Answers
She uses 800 mL of solution A; that is, 2% of those 800 mL is alcohol
Alcohol on a:
2% of 800 = 2*800/100 = 16mL
If we use x mL of b, the amount of alcohol is:
5% of x = 5*x/100 = x / 20
Total amount of alcohol: 16 + x/20
Total amount of solution mixture: 800 + x
The ratio:
(16 + x/20) / (800 + x) = 3%
(16 + x/20) / (800 + x) = 3/100
1600 + 5x = 2400 + 3x
Solving for x:
5x - 3x = 2400 - 1600

3x-1/5=x+1/3 pls help me
Answers
Answer:
x=4/15
Step-by-step explanation:
first you need to make common denominators for 1/5 and 1/3
the common denominator is 15
5*3=15, 3*5=15. 1*3=3, 1*5=5
new equation:3x-3/15=x+5/15
now subtract x from both sides: 3x-3/15=x+5/15
-x -x
2x-3/15=5/15
now you can add 3/15 to 5/15
2x=8/15
now for the last step, divide by 2 because there are 2 x's
2x/2=x 8/15 /2=4/15
x=4/15
Answer:
4/15
Step-by-step explanation:
3x-1/5 = x+1/3
make a common denominator
3x -3/15 = x + 5/15
next you can take away one x from both sides
2x - 3/15 = 5/15
then we want to have x alone on one side and everything else on the other
2x = 5/15 + 3/15
2x = 8/15
1x = 8/15 ÷ 2
1x = 8/30
simplify that
x = 4/15

from the given figure , we can see that RL=LQ and PK=KQ which means
that L and K are the mid points of sides RQ and PQ respectively .
The Mid Point Theorem states that
If the line segment adjoining the mid points of any of the sides of the triangle then the line segment is said to be parallel to the third side and is half of the length of third side .
which means LK parallel to RP and RP/2=LK ( ... by mid point theorem)
Substituting the values of LK = 2x-15 and RP = 2x-8 .
(2x-8)/2=2x-15
Multiplying both sides by 2
2x-8 = 2(2x-15)
So, the equation to solve for x is 2(2x-15)=2x-8
Simplifying further
2x-8 = 4x-30
4x-2x= 30-8

x = 11

Find the x-intercept of the line that passes through (-3,4) and is perpendicular to the graph of x-2y=7
Answers
Answer:
x - intercept = - 1
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
x - 2y = 7 ( subtract x from both sides )
- 2y = - x + 7 ( divide through by - 2 )
y = [tex]\frac{1}{2}[/tex] x + [tex]\frac{7}{2}[/tex] ← in slope- intercept form
with slope m = [tex]\frac{1}{2}[/tex]
given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{2} }[/tex] = - 2 , then
y = - 2x + c ← is the partial equation of the perpendicular line\to find c substitute (- 3, 4 ) into the partial equation
4 = 6 + c ⇒ c = 4 - 6 = - 2
y = - 2x - 2 ← equation of perpendicular line
to find the x- intercept let y = 0 into the equation and solve for x
- 2x - 2 = 0 ( add 2 to both sides )
- 2x = 2 ( divide both sides by - 2 )
x = - 1
the x- intercept of the perpendicular line is - 1 or (- 1, 0 )
