Answer:
There are no solutions
Step-by-step explanation:
No intersections or points that apply for the equations.
Any intersection between both lines is a solution. As these lines are parallel they have no solution. If they met at any point, 90 degree or not, there is solution, the solution will be a point. If they are on the same line, hitting all the same points, the solutions are infinite.
The data shows the number of salad wraps sold on each day for two weeks at a sandwich shop.
Week 1: 15, 13, 14, 14, 13, 12, 13
Week 2: 18, 3, 15, 15, 16, 14, 16
Which statement about the data is true?
a. The mean of Week 1 data is a good estimate of the sandwich shop's daily sales.
b. The mean of Week 2 data is a good estimate of the sandwich shop's daily sales.
c. Both the mean of Week 1 data and the mean of Week 2 data are good estimates of the sandwich shop's daily sales.
d. Neither the mean of Week 1 data nor the mean of Week 2 data is a good estimate of the sandwich shop's daily sales.

Martin's car had 86,456 miles on it. Of that distance, Martin's wife drove 24,901 miles,
and his son drove 7,997 miles. Martin drove the rest. How many miles did Martin drive?
Show work.
Answer:
Martin drove 53,558 miles.
Step-by-step explanation:
If you add up the amount of miles his son and wife drove, you get 32,898. To get the answer, you would subtract that from the total number of miles to get 53,558.

Rewrite in simplest terms: -2(3g-8g+8)-9g−2(3g−8g+8)−9g
Answer: 2g - 32
Step-by-step explanation:
-2 (3g - 8g + 8) - 9g - 2 (3g - 8g + 8) - 9g
First step is to use the distributive property to distribute 2.
The expression is now:
-6g + 16g - 16 - 9g - 6g + 16g - 16 - 9g
Now you put the like terms together..
-6g + 16g - 9g - 6g + 16g - 9g -16 - 16
All that is left to do is combine them!
(-6g + 16g - 9g - 6g + 16g - 9g) + (-16 - 16)
2g + (-32)
2g - 32
Hope that helped!

52% problems are pointless i.e. 48% are NOT pointless.
Recall that 1% = 1/100.
Therefore 48% = 48/100 = 12/25.
Let x be the number of problems that are not pointless.
x/175 = 12/25
x = 84
Answer:
84
Step-by-step explanation:
According to the question
175×48%
175×48/100
7×48/4
7×12

If two parents, one with brown eyes (a dominant trait) and the other with blue eyes (the recessive trait) produce one twin boy with blue eyes, what is the probability that a fraternal twin will transmit the blue eye allele to his or her offspring
Answer:
50 percent
Step-by-step explanation:
It is given that one of the parent with a dominant trait have brown eyes and the other parent with a recessive trait has blue eyes. They produce a twin boy with eyes that is blue in color. So the probability of the fraternal twin to transmit his allele of blue eye to his or her offspring is 50 percent.
And also the probability of the offspring to pass the allele on to his or her offspring is 50 %.
The product rule is used : 0.5 x 0.5 = 0.25 or 25%.

PLEASE HELPPPP ME!!!!!
Answer:
Problem 1: No
Problem 2: Yes
Step-by-step explanation:
Problem 1:
{(-2, 1), (-2, 3), (0, -3), (1, 4), (3, 1)}
This relation is not a function because there are two y-values, 1 and 3, related to one x-value, -2.
Thus, for a relation to be a function, every x-value must be related to exactly 1 y-value.
Problem 2:
{(0, 2), (3, 4), (-3, -2), (2, 4)}
In this relation, each x-value (domain) has exactly one y-value (range) that it is related to. Therefore, this is a function.

Find the x-Intercept and the y-Intercept of the line below. Click on "None" if applicable.
None
Answer: X-intercept is (2,0)
Y-intercept is (0,-2)
Step-by-step explanation:
Answer:
X-intercept is (2,0)
Y-intercept is (0,-2)
Step-by-step explanation:
The x intercept is the point at which the line hits the x-axis
in this picture, you can see that the given line hit the x-axis at (2,0)
The y intercept is the point at which the line hits the y-axis
so in this case you can see the the line hits the y-axis at (0,-2)
Bonus: if a line is horizontal it will not have an x intercept, and if a line is vertical, it will not have ay intercept
can someone fact check this to make sure its correct
