Passes through (-6,-1) and is parallel to y=-2/3x+1
Answer:
y=-2/3x-6
Step-by-step explanation:
y=mx+b
m=-2/3
y-y=m(x-x1)
y-(-1)=-2/3(x-(-6))
y+1=-2/3x-4
-1 -1
y=-2/3x-5
Answer:
[tex]y=-\frac{2}{3}x -5[/tex]
Step-by-step explanation:
Slope-intercept form:
[tex]y=mx+b\\\\y=(slope)x+(y-intercept)[/tex]
m is the slopeb is the y-interceptx and y are corresponding coordinate points (x,y)When two lines are parallel, their slopes are the same. Take the slope from the given equation and insert into the new:
[tex]y=-\frac{2}{3} x+b[/tex]
Now find the y-intercept. For this, insert the given coordinate points and the slope into the equation to solve for b:
[tex](-6_{x},-1_{y})\\\\-1=-\frac{2}{3} (-6)+b[/tex]
Simplify multiplication using the rule [tex]\frac{a}{b} *c=\frac{ac}{b}[/tex] :
[tex]-1=-\frac{2(-6)}{3} +b\\\\-1=-\frac{-12}{3} +b\\\\-1=\frac{12}{3} +b\\\\-1=4+b[/tex]
Use inverse operations to isolate the variable. Subtract 4 from both sides:
[tex]-1-4=4-4+b\\\\-5=b[/tex]
The y-intercept is -5. Insert:
[tex]y=-\frac{2}{3}x -5[/tex]

Samir is getting balloons for his mother's birthday party. He wants each balloon string to be 9 feet long. At the party store, string is sold by the yard. If Samir wants to get 59 balloons, how many yards of string will he need?
Answer:
177 yards
Step-by-step explanation:
3 feet - 1 yard, so we have 3 yards for each balloon.
He wants 59 balloons, so 59 x 3 = 177
Selena wants to sell hot dogs at a local sports arena. She must pay a fee of $25 $25 to sell hot dogs and estimates each hot dog will cost her $0.75 $0.75 . Selena plans on selling each hot dog for $2.00 $2.00 . What is the minimum number of hot dogs ( x x ) Selena needs to sell for the revenue to be greater than or equal to her cost?
Answer:
20
Step-by-step explanation:
Let the cost of 1 hot dog be $x.
2x ≥ 25 + 0.75x
2x - 0.75x ≥ 25
1.25x ≥ 25
x ≥ 20
THIS IS MY 4TH TIME POSTING THIS (I did it on my other account )Abby has just started training for a marathon. She ran 15 miles in total during her first week of training. She wants to add an additional 2 miles to her weekly total during each subsequent week. Write an explicit rule for the arithmetic sequence that represents this situation, and use it to find how many miles Abby will run during her twelfth week of training.
Please show work for full credit
Answer:
She will run 202 miles in 12 wks.
Step-by-step explanation:
y = 17x + 15
15 represents the # of miles she ran in the first week.
17 represents the amount of miles she will run each week
x represents the # of weeks
y = the total # of miles in 12 weeks.
To solve plug in 11 for x since she ran 15 miles the first week she has 11 more to go.
y = 17(11) + 15
y = 187 + 15
y = 202
Hope this helps!
202 miles Abby will run during her twelfth week of training.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
let the number of weeks she walk x.
As she ran15 miles in the first week.
and, she run 17 miles in each week.
let y be the total of miles in 12 weeks.
Then, the equation can be
y = 17x + 15
y = 17(11) + 15
y = 187 + 15
y = 202
Hence, 202 miles Abby will run during her twelfth week of training.

Find the slope and y-intercept of the line in each graph.
PLEASE HELP ASAP
Answer:
slope m = -2, y-intercept b = 1
Step-by-step explanation:
The slope is the change in y over the change in x.
Equation for slope: y2-y1/x2-x1=m
Since they already gave us the two points we just have to decide which one is our y2,y1 and out x2,x1 (which one you chose does not matter). And plug the numbers into the equation and get: -3-1/2-0=m, in this case, m=-4/2 and simplify it into -2. Now we have our slope.
The y-intercept is where the line crosses over the y-axis, and in our case, it is given to us in the (0,1) so our slope is 1.

Step-by-step explanation:
Consider the line y = 2x–4.
What is the slope of a line parallel to this line?
What is the slope of a line perpendicular to this line?
Parallel slope = 2
This is because the original line has slope 2. Parallel lines have equal slopes.
--------------------------
Perpendicular slope = -1/2
The original slope 2 or 2/1 turns into -1/2 after flipping the fraction and the sign. Note the original slope and perpendicular slope multiply to -1. This is true for any pair of perpendicular lines where neither line is vertical.
Answer:
the slope of the parallel line is 2x
the slope of line perpendicular is -1/2

Choose the statistic that is considered a measure of spread.
Mean
Standard deviation
Mode
Median
Answer:
The standard deviation is considered a measure of spread.
Step-by-step explanation:
Standard deviation is basically considered a measure of spread, measuring how far data values are from their mean.
Standard deviation helps in determining the nature of the variation of the data about the mean.For instance, in certain data sets, we may observe the same mean, but their range could be different, and data values in one data set may have been closely concentrated near the mean than the other data set values.
For example,
considering the data set
[tex]15, 15, 15, 14, 16[/tex]
The given data set has a mean: 15
considering the second data set
[tex]2, 7, 14, 22, 30[/tex]
The given data set has also a mean: 15
But, the values in the second data set are clearly more spread out. When the values of a data set are not spread out largely, then the set will have a low standard deviation.
Therefore, the standard deviation is considered a measure of spread.
