Answer:
-0.375
Step-by-step explanation:
Way one(the harder one):
Let the line which passes through (1,4) and (9,1) be f(x)=kx+b
Sub (1,4) and (9,1) in and we get [tex]\left \{ {{4=1k+b} \atop {1=9k+b}} \right.[/tex]
=> (9k+b)-(k+b)=1-4
8k=-3
k=-3/8 or -0.375
Therefore the slope of the line is -3/8 or -0.375
Way two(the easier one):
k= [tex]\frac{change in y}{change in x}[/tex] = [tex]\frac{1-4}{9-1}[/tex] = -[tex]\frac{3}{8}[/tex]
If g(x) = 3/2x + 4, what is the value of g(2)?
A. 10
B. 7
C. 5
D. 3.5
Answer:
The answer is option BStep-by-step explanation:
[tex]g(x) = \frac{3}{2} x + 4 \\ [/tex]
To find g(2), substitute the value of x that's 2 into g(x). That is for every x in g(x) replace it with 2
We have
[tex]g(2) = \frac{3}{2} \times 2 + 4 \\ = 3 + 4[/tex]
We have the final answer as

Select the correct answer.
Which equation represents the vertical line passing through (7,-3)?
A.
x = -3
B.
y = -3
C.
x = 7
D.
y = 7
Answer:
C. [tex]x=7[/tex]
Step-by-step explanation:
So we know that a vertical line is represented by [tex]x=[/tex] so we can already rule out two of the options. We also know that since the line runs vertically, all points will start with the same [tex]x[/tex] coordinate. This means that the correct answer is [tex]x=7[/tex]

a ratio of angel fish at a store is 5:4. the ratio of angel fish to goldfish is 4:3 . There are 60 clown fish at the pet store
how many angel fish are there?
how many goldfish are there
Answer:
an i oop
Step-by-step explanation:
Answer:
So if there are 60 clownfish and the ratio from clownfish to angelfish is 5:4, this is the equation you are looking at:
5:4 = 60:?
To find ? you have to do 60 divided by 5 which equals 12 and multiply it times 4 to see how many angelfish there will be if there are 60 clownfish.
12 x 4 = 48
So if there are 60 clownfish there will be 48 angelfish. The ratio is 60:48
For the next one, same thing if there are 48 angelfish, then you are looking at this equation:
4:3 = 48:?
Again, we solve like we did the last one.
48 divided by 4= 12
3 x 12= 36
So, if there are 48 angelfish there will be 36 goldfish. The ratio is 48:36
I hope this helps:)

2.) During typhoon ambo PAGASA tracks the amount of the accumulating rain fall. For the first three hour's of typhoon that rain fell at a constant rate of 25 mm per hour. The typhoon slows down for an hour ad started again at a constant rate of 20 mm per hour for the next 2 hour's . Write a piecewise function that models the amount of rain fall as function of time.
(this is for a friend)

In the graph of an inequality, the area above a solid line through the points (−5, 2) and (3, 2) is shaded.
Which inequality does this graph represent?
A. y ≥ 2
B. y ≤ 2
C. y 2
Answer:
A. y ≥ 2
Step-by-step explanation:
First the line is solid, a complete line not dotted so the inequality sign to use is : ≥ or ≤
The points have their y-coordinate vale as 2, (−5, 2) and (3, 2), this means the line crosses the y-axis at y=2 but because the shaded part is above this line, then the correct inequality will be :
y ≥ 2

I have 120 blocks. Each block is one of 2 different materials, 3 different colors, 4 different sizes and 5 different shapes. No two blocks have exactly the same all four properties. I take two blocks at random. What is the probability that these two blocks have exactly two of these four properties the same?
Answer: 0.54
Step-by-step explanatio;
We would have three in common out of 4 characteristics (4 out of 4 is not possible). There are 4 possible ways to share 3 out of 4 characteristics.
Denoting the characteristics as {M,C,Si,Sh} so P(B2={1,1,1,0}|B1={1,1,1,0}) is the probability that box 2 shares its first three characteristics with box 1 given that box one has characteristics
We now have
P(B2 has 3 elements in common with B1)=P(B2={1,1,1,0}|B1={1,1,1,0})xP(B1={1,1,1,0})+P(B2={1,1,0,1}|B1={1,1,0,1})xP(B1={1,1,0,1})+P(B2={1,0,1,1}|B1={1,0,1,1})xP(B1={1,0,1,1})+P(B2={0,1,1,1}|B1={0,1,1,1})xP(B1={0,1,1,1})
P(B2 has 3 elements in common with B1)=(4x5x24+3x4x30+2x3x40+1x2x60)1120x119= 0.084
which is close enough to the value from the simulation code (modified to count the number of 3-ties)
Now, I use the same reasoning to compute:
P(B2 has 2 or more elements in common with B1)=(19x20x6+11x12x10+9x10x12+14x15x8+7x8x15+5x6x20)1120x119= 0.54
Equation: (2-1)((3-1)+(4-1)+(5-1)) + (2)((3)+(4)) + (12) = 35 with a total of 119 possibilities.
answer: 35/119
Which phrase best represents the following?
"Six times the quantity of four plus a number"
0 64 + n)
O 6n + 4
0 6(4) + n
O 4n + 6
Answer:
C. 6(4) + n
Step-by-step explanation:
Six
6
Times the quantity of four
(4)
Plus a number
+n
The phrase that best represents six times the quantity of four plus a number is 6(4) + n.
What is a numerical expression ?A numerical expression is a form where we express a statement by number and their operations.
According to the given phrase six times the quantity four which is 6(4) plus a number.
6(4) + n.
What we have done here is we formed a numerical expression from a given statement.
Suppose we have given sum of 4 and thrice of a number is 10.
So, 4 + 3n = 10
3n = 10 - 4
3n = 6
n = 2.
So the number is 2.

At the beginning of the school year, Jamie had $500 in her savings account. She wants to have at least $200 left in the account at the end of the school year. Each week, she withdraws $30 for spending money. To determine how many weeks she can spend $30, Jamie wrote and solved this inequality. 500 − 30x ≥ 200 −500 −500 −30x ≥ −300 x ≥ 10 Review Jamie's work. What was her error?
Answer:
Step-by-step explanation:
Given the inequality solved by H=Jamie expressed as:
500 − 30x ≥ 200
We need to calculate the range of x of the inequality to determine the number of weeks she can spend $30 as shown:
500 − 30x ≥ 200
Subtract 500 from both sides
500 − 30x - 500≥ 200 - 500
− 30x ≥ -300
Divide both sides by -30
− 30x/-30 ≥ -300/-30
x ≤ 10 (note that the inequality sign changes after dividing both sides by a negative sign)
Jamie's error was that she didn't change the sense of inequality after dividing both sides by -30 hence rendering her solution incorrect
Hence the number of weeks is less than or equal to 10.
Answer:
Answer is B
Step-by-step explanation:
Jamie should have reversed the inequality when using the division property of inequality. is the right answer hope it helps
