Find the x- and y-intercept(s) of the line y = -5x + 8.
Answer:
x-intercept: (8/5, 0)
y-intercept: (0, 8)
Step-by-step explanation:
y = mx + b has y-intercept at b.
y = -5x + 8 has y-intercept at 8. The point is (0, 8).
The x-intercept occurs when y = 0.
-5x + 8 = 0
-5x = -8
x = 8/5
The x-intercept is 8/5, so the point is (8/5, 0).

A chemical company mixes pure water with their premium antifreeze solution to create an inexpensive antifreeze mixture. The premium antifreeze solution contains 60% pure antifreeze. The company wants to obtain 240 gallons of mixture that contains 15% pure antifreeze . How many gallons of water and how many gallons of the premium antifreeze solutin must be mixed?
An equation is formed of two equal expressions. The amount of premium antifreeze and the water that should be mixed are 60 gallons and 180 gallons, respectively.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the amount of premium anti-freeze solution mixed be represented by x, while the amount of water mixed be represented by y.
Since the total mixture should be 240 gallons, therefore,
x + y = 240
Solving for y,
y = 240 - x
Given the percentage of pure antifreeze, the mixture should contain is 15%. Therefore, we can write,
60%x + 0%y = 15%(240)
0.60x = 0.15(240)
x = 60 gallons
Now substitute the value of x in the first equation,
y = 240 - 60 = 180 gallons
Hence, the amount of premium antifreeze and the water that should be mixed are 60 gallons and 180 gallons, respectively.

Can someone solve both of these?
Answer:
4. A. y = -3x - 2
5. B. ¹/₃
Step-by-step explanation:
General form of a linear equation: y = mx + b
(where m is the slope and b is the y-intercept)
Question 4
From inspection of the graph, the y-intercept is at y = -2
The slope is the change in y divided by the change in x, so we can see that for every change of 1 x-value, the y-value decreases by 3 units.
Therefore, the slope is -3
So the equation of the line is y = -3x - 2
Question 5
Referring to the general form of the linear equation quoted above,
for equation y = ¹/₃x + 4
slope = ¹/₃y-intercept = 4A balloon artist claims the probability a randomly selected balloon pops while being molded is 0.10 and that balloons pop independent of other balloons. Part A. If we select a random sample of 3 balloons, what’s the probability that all of them pop while being molded?
Work Shown:
(0.10)^3 = (0.10)*(0.10)*(0.10) = 0.001
Answer:
0.001
Step-by-step explanation:
This can be modeled as a binomial distribution as:
There is a fixed number (n) of trialsEach trial is either a success or failureAll trials are independentThe probability of success (p) is the same in each trialThe variable is the total number of successes in the n trialsLet "success" be the balloon popping.
⇒ trials (n) = 3
⇒ probability of success (p) = 0.10
To find the probability that all 3 of the balloons pop, use the binomial distribution with x = 3:
[tex]\begin{aligned} \displaystyle P(X=x) & =\binom{n}{x} \cdot p^x \cdot (1-p)^{n-x}\\\\\implies P(X=3) & =\binom{3}{3} \cdot 0.1^3 \cdot (1-0.1)^{3-3}\\ & = 1 \cdot 0.001 \cdot 1\\ & =0.001 \end{aligned}[/tex]

30% of Elm trees have a certain disease. If you sample 80 elm trees, what is the probability that less than 20 trees have the disease?
The probability that less than 20 trees have the disease is; 0.135
How to find the Probability?
The formula for binomial probability is;
P(X = x) = ⁿCₓ * pˣ * (1 - p)⁽ⁿ ⁻ ˣ⁾
We are told that 30% of Elm trees have a certain disease. Thus;
p = 30% = 0.3
n = 80
x = 20
Thus, probability that less than 20 trees have the disease is;
P(X < 20) = P(X = 0) + P(X = 1) + P(X = 2) + ....... + P(X = 19)
Using a binomial probability calculator online gives us;
P(X < 20) = 0.135

75 POINTS Need an immediate answer please brainliest will be given! A train left a station travelling to a city at 30 mph. The train traveled 1/3 of the distance at 30 mph and the remaining distance at 40 mph. Two hours later a car left the same station and traveled in the same direction to the same city. The car traveled the first 3 hours at 35 mph and the remaining distance at 51 mph. Knowing that they both reached the city at the same time, find the distance between the station and the city in terms of miles.
The value of distance between the station and the city in terms of miles which train and car travelled at interval of 2 hours is 129.6 miles.
What is the rate of speed?The rate of speed is the rate at which the total distance is travelled in the time taken. Rate of speed can be given as,
r=d/t
Here, (d) is the distance travelled by the object and (t) is time taken but the object to cover that distance.
The train traveled 1/3 of the distance at 30 mph and the remaining distance at 40 mph. Let t is the time the train has taken to travel and x is the distance it travelled. Thus,
[tex]t=\dfrac{\dfrac{1}{3}x}{30}+\dfrac{\dfrac{2}{3}x}{40}\\t=\dfrac{x}{90}+\dfrac{x}{60}\\t=\dfrac{2x+3x}{180}\\t=\dfrac{5x}{180}\\t=\dfrac{x}{36}[/tex]
After two hour a car left the same station traveled the first 3 hours at 35 mph and the remaining distance at 51 mph. Let t is the time the car has taken to travel and x is the distance it travelled. Thus,
[tex]t+2=3+\dfrac{(x-3\times35)}{51}[/tex]
As t is same, thus put the value of t in this equation,
[tex]\dfrac{x}{36}=3-2+\dfrac{(x-3\times35)}{51}\\\dfrac{x}{36}=3-2+\dfrac{(x-3\times35)}{51}\\\dfrac{x}{36}=1+\dfrac{(x-105)}{51}\\\dfrac{x}{36}=\dfrac{(51+x-105)}{51}\\51x=36x-54\times36\\51x-36x=1944\\x=\dfrac{1944}{15}\\x=129.6[/tex]
Thus, the value of distance between the station and the city in terms of miles which train and car travelled at interval of 2 hours is 129.6 miles.

The diagram shows a square pizza box with side lengths of 16 inches. In the box is a circular pizza with a radius of 8 inches. What is the difference between the area of box and the pizza?
Answer:
54.9381 square inches
Step-by-step explanation:
Find the areas of both the square box and the circular pizza.
The equation for the area of a square is A = s^2. (or A = lw)
A = 16^2 = 256 square inches
The equation for the area of a circle is A = πr^2.
A = π(8^2) = 64π = 201.0619 square inches
Now subtract the areas.
256 - 201.0619 = 54.9381 square inches
