answer:
y=2x+6
solution:
Alright, since the line is PARALLEL, the slope will remain the same. let call the # we will add to that b (like the 5 in y=2x+5).
so the formula will be y=2x+b
to find be, we will plug in one of the ordered pairs
6=2(0)+b
6=0+b
b=6
So, our equation is y=2x+6
to check:
(-3,0)
0=2(-3)+6
0=-6+6
0=0
Answer:
y = 2x + 6
Step-by-step explanation:
The equation for this is y=mx+b, m being for slope and b being the y-intercept.
The first and easiest way to figure out this first is by finding the slope. Now because you have the information that it needs to be parallel, it's very fast and simple. Parallel means that it has the same slope and the lines will never cross each other. So, since the slope for this is 2, the new line you will be making will also have a slope of 2.
EXTRA NOTE- if it were perpendicular, you'd want to do the opposite reciprocal. Instead of being 2, it'd be -1/2, but luckily we're just dealing with parallel.
Now we need to find what the y-intercept is. Since math basically has a formula for everything, you will be using y-y(1)= m(x-x(1)). Now that looks slightly confusing, but basically you will just plug your y value into the y(1) and x coordinate into x(1) to simplify into slope intercept form (don't forget your slope!). It's always easier to use positive numbers for this, so I'll be using the coordinates (0, 6) and plug it in.
REMEMBER- coordinates are (x, y). Don't get it mixed up!
1. Write out your equation: y - 6 = 2 ( x - 0 )
2. Distribute: y - 6 = 2x - 0
3. Add 6 to the other side to get into your slope intercept form: y = 2x + 6
And that's how you get your line. Hope this helped and made at least some sense. :)

Valerie took a quiz with 10 questions. If she answered 2/5 of the questions correctly, how many did she get wrong?
Answer:
3/5; 6 questions
Step-by-step explanation:
She got 3/5 of the questions wrong
So,
3/5 of 10 = 3 * 2 = 6 questions
Answer:
3/5 = 6/10
Step-by-step explanation:
Valerie only got 4 questions correct meaning she got 6 questions incorrect.
2/5 = 4/10
which means
3/5 = 6/10.
Meaning she only got 6 wrong.

Complete question :
Kenny is putting a brick border around his irregular shaped garden. Before installing the border, Kenny must
cut the bricks to fit the angles of the garden. Use the given measures to answer the question.
mzA=x
mZB=(5x-5)
m2C =(2x +20)
mZD=(3x-15)
mZE =(4x)
What are the angle measures of each vertex of the garden? Show your work.
Answer:
m<a=36
m<b=175
m<c=92
m<d=93
m<e=144
Step-by-step explanation:
Use the given measures to answer the question. MZA= x mZB = (5x – 5)º M2C = (2x+20)° m_D = (3x –15)° MZE = (4x)
We are given five angles :
Using the sum of interior angle of a regular polygon formula :
180(n - 2) ; where, n = number of sides ;
180(5 - 2) = 180 * 3 = 540°
The sum of the 5 angles should add up to 540°
x + (5x - 5)° + (2x + 20)° + (3x - 15)° + 4x = 540
5 + 20 - 15 + 5x + 2x + 3x + 4x + x = 540
15x = 540
15x = 540
15x = 540
x = 36
mzA= 36°
mZB=(5(36)-5) = 175°
m2C =(2(36) +20) = 92°
mZD=(3(36)-15) = 93°
mZE =(4(36) = 144°

A random sample of students were asked whether they prefer milk juice or water is it results are summarized in the table.
Answer:
C
Step-by-step explanation:
The probability of students response is milk is 0.311.
What is probability?Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.
For the given situation,
The table shows the students preference of milk, juice or water.
Total number of students preferred milk = 14
Total number of students = 45
Thus the probability that the students response is milk is
[tex]P(e)=\frac{14}{45}[/tex]
⇒ [tex]P(e)= 0.311[/tex]
Hence we can conclude that the probability of students response is milk is 0.311.

Without finding the quotient, is the value of the expression (-3 1/3 + 3 1/2) ÷ (-1/4) positive or negative? Explain.
PLZ HELP ASAP
The expression (-3 1/3 + 3 1/2) ÷ (-1/4) is a division of a positive numerator by a negative denominator, and thus the quotient is negative.
What is an expression?
In mathematics, an expression is a combination of numbers, symbols, and operators (such as +, -, x, ÷) that represents a quantity or a mathematical relationship between quantities.
To determine whether the value of the expression (-3 1/3 + 3 1/2) ÷ (-1/4) is positive or negative, we need to analyze the signs of the numerator and denominator.
First, let's convert the mixed numbers to improper fractions:
-3 1/3 = -10/3
3 1/2 = 7/2
So the expression becomes:
(-10/3 + 7/2) ÷ (-1/4)
Now let's analyze the signs:
The numerator is the sum of two fractions with different signs, so we need to subtract their absolute values and use the sign of the larger one.
|10/3| = 10/3 and |7/2| = 7/2, so the larger fraction is 10/3.
-10/3 + 7/2 = (-20 + 21) / 6 = 1/6, so the numerator is positive.
The denominator is negative because it is a fraction with a negative denominator.
Therefore, the expression (-3 1/3 + 3 1/2) ÷ (-1/4) is a division of a positive numerator by a negative denominator, and thus the quotient is negative.

Answer:

Step-by-step explanation:
Hello There!
First things first, we should find the rate of change / slope
given two points we can find the slope by using the slope formula which is
(let m be slope)
[tex]m = \frac{y_2-y_2}{x_2-x_2}[/tex]
To find the slope all we have to do is plug in the points
(1,5),(2,10)
remember the first numbers in an ordered pair are the x values and the second numbers are the y values
we also plug in the points of the second ordered pair first so
[tex]m=\frac{10-5}{2-1} \\10-5=5\\2-1=1\\m=\frac{5}{1} or5[/tex]
Knowing the slope we can create an equation to find the x value (a)
y=5x
given the y value we plug in y and solve for x
15=5x
divide each side by 5
15/5=3
5x/5=x
we're left with
x=3
so we can conclude when y =15 x = 3 therefore 3 is your answer
