What is the area of this triangle in the coordinate plane?
Answer:
A=25
Step-by-step explanation:
Triangle area formula: A= base x height/2
Base:12-2=10
Height:9-4=5
(10x5)/2=25
So it's 25.
1. Carbon-14 has a half-life of 5,700 years. Scientists use this fact to determine the age of things made of organic material. Suppose the average page of a book containing approximately 0.5 mg of carbon-14 is put into a time capsule. How much carbon-14 will each page contain after each of the following numbers of years?
a. How many half-years is each quantity of years?
b. How much carbon-14 remains after the number of years shown to the left?
c. Challenge: see if you can create a table that uses 5700 as part of the exponent, and the actual number of years given above. Challenge function:
Answer: Since 5700 years is the "half-life" exactly 0.25 mg will remain.
Step-by-step explanation: Well, we know that half of it will change into another form in 5700 years, so if you start with .5 mg than in 5,700 years you would have half or .25 mg. 11,400 is another half life so half of .25 = .125 mg. 22,800 is two more half lives so half .125 twice.

The graph for the equation y = x minus 4 is shown below.
On a coordinate plane, a line goes through (0, negative 4) and (4, 0).
Which equation, when graphed with the given equation, will form a system that has an infinite number of solutions?
O- y - x = -4
O- y - x = -2
O- y - 4 = x
O- y + 4x = 1
Answer: A: y-x = -4
Step-by-step explanation:
To have an infinite number of solutions, two linear equations must be on top of each other, (so they intersect at every point). What this question is really asking is the equation for the plotted line!
This is simple enough:
two points are given, so lets fine the slope:
Slope = (y2-y1)/(x2-x1) = (-4 -0)/(0-4) = -4/-4 = 1
the slope is 1:
putting this into slope intercept form, we have y = x + b.
since b is the y intercept, and that is already given as -4, our completed equation is:
y = x - 4
which can be rewritten as y - x = -4
So your answer is the first option.

Answer:
p*15%
p*15%*6%
Step-by-step explanation:
Answer:
Part A: 0.85p
Part B: 0.901p
Step-by-step explanation:
The phone's original price: 100%
The phone's sale price: 15% off the original price
p = original price of the phone
Part A:
100% - 15% = 85%
85% = 0.85
The expression: 0.85p
Part B:
6% = 0.06
0.06 * 0.85p ==> (the sales tax * the discounted price of the phone)
0.051p
0.85p + 0.051p
0.901p

for each of the number lines, write an absolute value equation in the form |x-c|=d, where c and d are some numbers, to satisfy the given solution set.
An absolute value that can represent the solution set is: |x - 2|=4
From the number line, we have the domain of the x values to be:
x = -4 to 6
This means that the least x value is -4, and the largest is 6
The absolute value equation is given as:
|x - c|=d
Assume that d = 4.
So, we have:
|x - c|=4
Assume that c is 2.
So, we have:
|x - 2|=4
When solved, we have:
x = -2 or x = 6
-2 and 6 are within the domain of the number line.
Hence, an absolute value that can represent the solution set is: |x - 2|=4

Number 1:An object on earth has a mass of 34 g and an acceleration of 9.8 m/s2. What is its weight (force)?
Number 2:f the mass of an object is 57gm and the volume is 3cm cubed. What is the density of the object? (do not include units in your answer)
Answer:you gotta divide
Step-by-step explanation:
Answer:
1. 333.2 N
2. 19
Step-by-step explanation:
1. So first lets write what we have :
Mass= 34g
Acceleration=9.8m/s^2
Force= x
Formula: Force= Mass * Acceleration
Force= 34 * 9.8
Force = 333.2N
So the force is equal to mass * acceleration
The answer then becomes 333.2N
2. Mass = 57gm
Volume= 3cm^3
Density= x
Density = mass / volume
The density is equal to the mass divided by the vilume thus 57 / 3 = 19
Density = 19

Answer:
81/450 or 18%
Step-by-step explanation:
Since you are trying to get the probability model for the chance silver will be selected, you add up 81,117 and 252. This gets you 450denominator and since you are trying to find the probability for sliver, you put 81 in the numerator. This gets the you fraction 81/450. If you divide it, you get 0.18. Now if you are trying to make a decimal into a percent, you move the decimal point two spots to the right. So, 0.18 becomes 18%.

A cable company charges $70 per month for cable service to existing customers.
a. Find a linear equation representing the relationship between x, the number of months of service, and y, the total amount paid in dollars by an existing customer.
b.For new customers, there is an additional one-time $100 service fee. Repeat the previous problem for new customers.
c.When the two equations are graphed in the coordinate plane, how are they related to each other geometrically?
Answer:
a: y=70x
b: y=70x+100
c: They are parallel to each other, with equation b's line being 100 dollars above equation a.
Step-by-step explanation:
They both have the same slope (70), but new customers will have a y intercept of 100 because of the one-time fee.
Don't forget to like and rate!
The equation is given by y = 70x and for the new customers it is given by y = 70x + 100.
A linear equation is of the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept
Let x represent the number of months of service, and y represent the total amount
a) A cable company charges $70 per month, hence:
y = 70x
b) The is an additional one-time $100 service fee, hence:
y = 70x + 100
Hence the equation is given by y = 70x and for the new customers it is given by y = 70x + 100
