Answer:
Step-by-step explanation:
x - 4y = 4
-4y = -x + 4
y = 1/4x - 1
y + 1 = 1/4(x + 8)
y + 1 = 1/4x + 2
y = 1/4x + 1

12=7x+6-5x
Answer:
x = 3
Step-by-step explanation:
12 = 7x + 6 -5x {Combine like terms}
12 = 7x - 5x + 6
12 = 2x + 6 {Subtract 6 from both sides}
12 - 6 = 2x
6 = 2x {Divide both sides by 2}
6/2 = 2x/2

Let f(x)=5x-4 and g(x)=x^2-1. Find (g*f)(-1)
Answer:
D. 80
Step-by-step explanation:
Given:
f(x) = 5x - 4,
g(x) = x² - 1
Required:
(g o f)(-1)
SOLUTION:
(g o f)(-1) = g(f(-1))
Plug in -1 for x into the function, f(x) = 5x - 4:
g(f(-1)) = g(5(-1) - 4)
= g(-5 - 4)
= g(-9)
Plug in -9 for x in the function, g(x) = x² - 1
g(-9) = (-9)² - 1
= 81 - 1
= 80.
Therefore, (g o f)(-1) = g(f(-1)) = 80
D. 80 is the correct answer.

I need a fast answer !! A bag has 7 blue marbles and 3 red marbles. What is the probability of drawing two red marbles, if the first marble is replaced after it is drawn? A. 1/7 B. 1/3 C. 3/10 D. 9/100
Answer:
Step-by-step explanation:
9/100 i believe as you would multiply 3/10 by 3/10 due to the fact the marble is being replaced so the probability of getting a red marble the second time will be more unlikely. If I'm right please thank me or give me brainly. Hope this helps :)
The probability of drawing two red marbles, if the first marble is replaced after it is drawn, is 9/100.
What is Probability?
It is a branch of mathematics that deals with the occurrence of a random event.
The probability of drawing a red marble on the first draw is 3/10, since there are 3 red marbles out of a total of 10 marbles.
Since the first marble is replaced before the second draw, the probability of drawing a red marble on the second draw is also 3/10.
To find the probability of drawing two red marbles in a row, we multiply the probabilities of the individual events, since they are independent:
P(drawing two red marbles) = P(red on first draw) × P(red on second draw)
P(drawing two red marbles) = (3/10) × (3/10)
= 9/100
Therefore, the probability of drawing two red marbles, if the first marble is replaced after it is drawn, is 9/100.

What is Number system?A number system is defined as a system of writing to express numbers.
A number line can be defined as a pictorial representation of numbers on a straight line.
In the given number line each line represents 0.25 (zero point two five value).
As B is in between -2 and -3.
So B value is between minus two and minus three
The values which can be between -2 and -3 are -2.25, -2.5, -2.75.
The decimal value positioned at point B is -2.25

What is the equation of the graph shown?
Greetings from Brasil...
As we have a line, the function will be given by the expression:
F(X) = AX + B
where
A = ΔY/ΔX
B = where the line intersects the Y axis
Looking at the graph we have already concluded that
B = - 3
A = ΔY/ΔX
A = (5 - 3)/(4 - 3) see attached picture
A = 2
So,
F(X) = AX + B
F(X) = 2X - 3Graph t> -2 on a number line

Answer:
f(x)= 3|x-3|+1
Step-by-step explanation:
Reason why it's not +3 is because it's the reverse when graphed. But that only applies for the numbers in the brackets. If it's in the brackets and it's positive, you go to the left. If it's negative, then it goes to the right. And as you see, the V isn't on the point (0 , 3), and is in fact, above it, by 1. The graph has also been stretched vertically by 3, it looks like. Hope that was helpful for you!
Answer:
y = 2|x-3| + 1
Step-by-step explanation:
The vertex of g(x) = |x| is at (0,0)
We have moved the vertex to ( 3,1)
y = f(x) + C C > 0 moves it up
y = |x| + 1 for the shift up 1
y = f(x + C) C < 0 moves it right
y = |x-3| for the shift to the right 3
y = Cf(x) C > 1 stretches it in the y-direction
y = 2|x| since it is stretched by a factor of 2 in the y direction
Combining
y =2|x-3| + 1

Answer:
x>-2
Step-by-step explanation:
first you subtract 10 from both sides to find x
10-3x-10<16-10
-3x<6
now here you divide both sides by -3
-3x/-3<6/-3
BUT since you are dividing by a negative number the sign will have to flip
so the answer will be
x>-2

There are two options for buying crickets option A.7 pounds of crickets for 3.15 option B.3 pounds of crickets for 1.47 which option is better to buy justify your answer
Answer: 7
pounds for 3.15 is a better option
Step-by-step explanation:
Here in this question, we want to know which of the two options is a better option for buying crickets.
To know the better option, we shall be needing the unit price in whatever system to be used;
7 pounds of crickets for 3.15;
so the unit price here will be 3.15/7 = 0.45 per pound
For the second system, we have 3 pounds for 1.47 so the unit price will be 1.47/3 = 0.49 per pound
As we can see, the first option commands a cheaper price per unit, so it is the better option to buy

Theorem what is
c known as?
That passes through (-4,0) and is parallel to y= -2x+1
Answer:
y = -2x - 8
Step-by-step explanation:
Parallel lines always have the same slope. Here, it is -2.
So, our equation so far looks like this:
y = -2x + b, where b is the y-intercept
We need to find b. We know our line passes through (-4, 0), so let's plug -4 in for x and 0 in for y:
y = -2x + b
0 = -2 * (-4) + b
0 = 8 + b
b = -8
Since b = -8, our equation is thus y = -2x - 8.
