Find the y intercept (if there is one) put your answer as a ordered pair.
(-2,6) (1,6)
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 ).

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?
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

A passenger car will go 310 miles on 15.5 gallons of gasoline in city driving. What is the rate in miles per gallon?
The rate is
mpg.
(Simplify your answer.)
Answer:
20 mpg
Step-by-step explanation:
Given:
A passenger car will go 310 miles on 15.5 gallons of gasoline in city driving. What is the rate in miles per gallon?
Solve:
To find the rate in miles per gallon we have to divide.
Knowing that "Per" means "Each/One"
Hence, to find miles per gallon we divide :
Miles by Gallons
⇒ 310/15.5
Solving using long division format: ( Multiply both by 10 first)
[tex]155\overline{|\smallspace3100}\:\:\:\:[/tex]
Divide 310 by 155 to get 2:

the lewis family drove 45.6 miles to the river. It took them 1.2 hours to get there. How fast did they drive? Round to the nearest whole number
The most appropriate choice for speed will be given by
Speed of the car of Lewis family = 38 miles/hours
What is speed?
Distance travelled by an object per unit of time is called speed.
If d is the distance travelled and t is the time taken, then speed is calculated by-
Speed = [tex]\frac{d}{t}[/tex]
Here, speed is a scalar as the direction is not taken into account.
Distance drove by Lewis family to the river = 45.6 miles
Time taken by the Lewis family to go to the river = 1.2 hours
Speed of the car of Lewis family = [tex]\frac{45.6}{1.2}[/tex]
= 38 miles/hour

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;

Thus, the number written in the standard form is 2.5×10⁻⁴.

A constant force is applied to an object, causing the object to accelerate at 12.50 m/s/s. What will the acceleration be if both the force and the
mass are doubled? Round to two decimal places and use SI units.
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
So:
a₂ = 12.5m₁ / m₁
a₂ = 12.5 m/s²

what does this mean 3|-3| the whole |-3| thing I'm confused please help
|-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.

Which expression does not belong with the other three? justify your response.
To find the equation that does not belong with the other three we have to solve each equation.
Given the equation:

[tex]\begin{gathered} \frac{x\cdot27}{27}=\frac{54}{27} \\ x=2 \end{gathered}[/tex][tex]4\cdot x\cdot5=40[/tex]4 :
[tex]\begin{gathered} \frac{4\cdot x\cdot5}{4}=\frac{40}{4} \\ x\cdot5=10 \end{gathered}[/tex]5
[tex]\begin{gathered} \frac{x\cdot5}{5}=\frac{10}{5} \\ x=2 \end{gathered}[/tex]In consequence, the equation that does not belong with the other three is:
[tex]5\cdot2\cdot x=40[/tex]because its solution, 4, is different from the solution to the other equations (2).
If we change the 5 in the equation by a 10 and solve the equation we get:
[tex]\begin{gathered} 10\cdot2\cdot x=40 \\ \frac{10\cdot2\cdot x}{10}=\frac{40}{10} \\ 2\cdot x=4 \\ \frac{2\cdot x}{2}=\frac{4}{2} \\ x=2 \end{gathered}[/tex]And now the equation (with a 10) belongs with the other three
Select the correct equation and correct answer to solve for X using the triangle below.
The correct equation to solve for x is 2(2x-15)=2x-8 , and the value of x is 11 .
in the question ,
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
2x = 22
x = 11
Therefore , the correct equation to solve for x is 2(2x-15)=2x-8 , and the value of x is 11 .

how to find the range of values where sin will consistently increaseIn trigonometry, the first basic functions are the sin, cos and tan.
In a right angle triangle the sin is represented as the ratio of opposite to hypotenuse. cos is represented as the ratio of the adjacent to hypotenuse, while tan is the ratio of opposite to adjacent or ratio of sin to cos.
Plotting the graph of sin functions, the pattern forms a sinusoidal pattern which bears its maximum value at sin 90degrees and the minimum value at sin 0 degrees.

Find the x-intercept of the line that passes through (-3,4) and is perpendicular to the graph of x-2y=7
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 )
