What is the value of x?
Enter your answer in the box.
Answer:
12
Step-by-step explanation:
the angles on top of a line (or below a line) sum up to 180 degrees, as a line stands in that regard for a flip from left to right - which is a half circle or 180 degrees.
therefore, the sum of both angles must be 180.
10x - 20 + 6x + 8 = 180
16x -12 = 180
16x = 192
x = 12
What is the slope of the line? What is the y-intercept of the line? y = -x - 6
Answer:
m = -1
y intercept = -6
Step-by-step explanation:
The given equation of the line is ,
[tex]\implies y = -x -6[/tex]
We know that the Standard equation of Slope Intercept Form of the line is,
[tex]\implies y = mx + c[/tex]
Where ,
m is slope c is y intercept .On comparing to the Standard form of the line we get ,
[tex]\implies Slope = -1 [/tex]
[tex]\implies y - intercept= -6 [/tex]
Slope: -1
Solution:This equation is written in slope-intercept form (y=mx+b).In this formula, "m" stands for the line's slope and "b" stands for the y-intercept of the line.Also, please notice that the slope of the line is the coefficient of x (the number next to x)If we don't have a number next to x, then the coefficient is equal to 1.If we have a minus sign next to x, then the coefficient is equal to -1.Therefore, the slope of the line is -1.Now, the y-intercept is a constant that's subtracted from/added to the slope.Therefore, the y-intercept of the line is -6.Hope it helps.

How do I complete the table?
Answer:
From left to right, fill in 3.5 and 6.5
Step-by-step explanation:
Use the given formula to calculate y for the given values of x.
When x = 0.5, y = 3(0.5) + 1/0.5
y = 1.5 + 2
y = 3.5 if x = 0.5
When x = 2, y = 3(2) + 1/2
y = 6 + 0.5
y = 6.5 if x = 2
a person earns 17/5 dollars in 1/2 hours. What is the unit rate in dollars pure hour
Answer:
35 2/3 dollars per hour
Step-by-step explanation:
The unit rate in dollars per hour is 6.8 dollars per hour.
To find the unit rate in dollars per hour, we need to divide the amount earned by the time taken.
The person earns 17/5 dollars in 1/2 hours. To calculate the unit rate in dollars per hour, we divide the amount earned (17/5 dollars) by the time taken (1/2 hours):
Unit rate = (Amount earned) / (Time taken) = (17/5 dollars) / (1/2 hours)
To divide fractions, we multiply the numerator of the first fraction by the reciprocal of the second fraction:
Unit rate = (17/5 dollars) x (2/1 hours)
Simplifying the expression:
Unit rate = (17 x 2) / (5 x 1) = 34/5 = 6.8
Therefore, the unit rate in dollars per hour is 6.8 dollars per hour.

Answer:
Answer is 0.14.
Step-by-step explanation:
The probability that a student earns a grade of D or F is 0.14.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
To find the probability that a student earns a grade of D or F, we need to add the frequencies of these two grades and divide by the total number of students:
P(D or F) = (3 + 2) / 35
P(D or F) = 5 / 35

Explanation:
Angles 4 and 8 are corresponding angles since they are both in the southwest corner of their respective 4 corner configuration.
Corresponding angles are congruent when we have parallel lines like this.
Set the expressions equal to each other and solve for x
angle 4 = angle 8
x+20 = 2x+5
x-2x = 5-20
-x = -15
x = 15
Use this x value to find the two angles to help confirm we have the correct x value, and to finish up to answer the question.
angle 4 = x+20 = 15+20 = 35angle 8 = 2x+5 = 2(15)+5 = 30+5 = 35So that's why the answer is B) 35 degrees

Step 2: By adding like terms.
12x + 12 = 3
Step 3: Transfer
12x = 3 - 12
Step 4: Subtract

[tex]2y - 3 = \sqrt{ {3y}^{2} - 10y + 12} [/tex]
absurd answers will be reported!!
Answer:
y = 3
Step-by-step explanation:
2y - 3 = [tex]\sqrt{3y^2-10y+12}[/tex]
square both sides to remove sqrt bracket
(2y - 3)^2 = ( [tex]\sqrt{3y^2-10y+12}[/tex] )^2
simplify both sides
(2y - 3)(2y - 3) = [tex]3y^2[/tex] - 10y + 12
[tex]4y^2[/tex] - 12y + 9 = [tex]3y^2[/tex] - 10y + 12
bring all value to left side
[tex]y^2[/tex] - 2y - 3 = 0
factor
(y - 3)(y + 1)
solve for y
y = 3, y = -1
When plugged back into the equation, only y = 3 is true
Answer:
y = 3
Step-by-step explanation :
[tex]2y - 3 = \sqrt{ 3y² - 10y + 12} [/tex]
Swap the sides both of the equation.
[tex]\sqrt{ 3y² - 10y + 12} = 2y - 3 [/tex]
To remove the brackets of equations square both side and simplify .
3y² - 10y + 12 = 4y² - 12y + 9
Move the expression to left-hand side and change its sign.
3y² - 10y + 12 - 4y² + 12y - 9 = 0
collect like terms
3y² - 4y² - 10y + 12y + 12 - 9 = 0
-y² + 2y + 3 = 0
Change the sign of expression. because it helps to solve.
y² - 2y - 3 = 0
Splits the term -2y
y² + y -3y - 3 = 0
Factor out y from the first pair and -3 from second pair of expression.
y ( y + 1 ) - 3 ( y + 1) = 0
Factor out y + 1 from the expression.
( y + 1 ) ( y - 3 ). = 0
When product and factors equals 0. at least one factor is 0.
y + 1 =0
y - 3 = 0
Solve for y
y = -1 and y = 3
If we plug the 3 as y in the expression we find that y = 3 is the true solution of this expression.
This equation has one solution which is y = 3.

Hello there ,
The answer to this equation would be:
A=.50j+9
Step-by-step explanation:
this answer should be correct because he started with 9,
and he is selling each cup (j) for 0.50
Let me show you an example:
Ok lets say he sold 10 (j) cups:
you would replace the (j) with the 10
A=0.50(10)+6
A=5+6
A=11 and he would have $11

Answer: B. 80
Step-by-step explanation:
Solve the equation they've given you:
[tex]\frac{3}{4} S=60\\\frac{3S}{4} =60\\3S=60*4\\3S=240\\S=80[/tex]
Answer:
B. 80
Step-by-step explanation:
(3/4)S = 60
You want to isolate S. S is being multiplied by 3/4.
You need to multiply 3/4 by its reciprocal to get rid of the 3/4 on the left side.
The reciprocal of 3/4 is 4/3.
The rule with equations is that you are allowed to multiplied both sides of an equation by the same number. Multiply both sides of the equation by 4/3.
4/3 * (3/4) * S = 4/3 * 60
12/12 * S = 4/3 * 60/1
1 * S = 240/3
S = 80

Step-by-step explanation:
Probability is equal to the amount of desirable outcomes divided by the total amount of outcomes. Each coin has two sides, and there are three of them. This accounts for a total of 2^3 or 8 outcomes. Now, we need to find the amount of outcomes where two or more coins land on heads. We can start by listing those possibilities: THH, HTH, HHT, and HHH. Notice that the first three are just three ways of rearranging the same result. We can see that there are four desirable outcomes. This means the probability is 1/2.

Proportional relationships between x and y help anyone
Answer:
The table on the right, the green table, is the one that shows a proportional relationship
Step-by-step explanation:
A walking path across a park is represented by the equation y=-3x - 6. A new path will be built perpendicular to this path. The paths will intersect at the point (-3,3). Identify the equation that represents the new path 10- 20 10
The equation of the new path would be y=1/3x+4.
Explanation
If two lines are perpendicular, their slopes are negative reciprocals of each other. The original equation is written in slope-intercept form, y=mx+b, where m is the slope. In this equation, m=-3=-3/1.
In the new equation, the slope would be the opposite sign and flipped; this means it would be 1/3.
We can use the point given, the slope and slope-intercept form to write the equation of the new line:
y=mx+b
3=1/3(-3)+b
3=1/3(-3/1)+b
3=(-3/3)+b
3=-1+b
Add 1 to both sides:
3+1=-1+b+1
4=b
This makes the equation y=1/3x+4.
Answer:
B
Step-by-step explanation:
> if the lines are perpendicular then their slopes are negative reciprocal so
y=mx+b , is the general form where is m = slope
y= -3x -4, old path has slope m= -3
y= (1/3)x +b , is the new path with slope m=(1/3)
>if the paths intersect at (-3,3) then this point is on the new path as well
y= (1/3)x +b, now substitute x= -3, and y=3 to find b
3 = (1/3)(-3)+b , divide -3/3
3= -1 +b, add 1 to both sides
4 = b
>the equation of the new path is
y= (1/3)x +4
