Answers
Answer:
slope = 4/=7
y int = -7
Step-by-step explanation:
slope = rise/run
slope = 4/-7
y int:
y = 4(0)-7
y= 0-7
y int = -7
The slope and y-intercept of the equation are 4 and -7 respectively.
What is the equation of a line?The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.
The given equation of a line is y=4x-7.
By comparing y=4x-7 with y=mx+c, we get
m=slope = 4 and c=y-intercept=-7
Therefore, the slope and y-intercept of the equation are 4 and -7 respectively.

Add 2 both sides of the equation
2x-2=3x-12
2x-2+2=3x-12+2
Simplify
2x=3x-10
Subtract 3x from both sides of the equation

John bought a pack of 18 cards for $2.99. About how much did each card cost?
Answers
Answer:
0.166
Step-by-step explanation:
Bought 18 cards for $2.99, so you can write it like this:
18 = 2.99
Since you want to find the value of one card, u could write that like this:
1 = x (where x is the unknown value of 1 card)
To get from 18 to 1, you divide by 18, so to get to 2.99 to x you must divide by 18 as well.
So 2.99/18 = 0.166
therefore x = 0.166
So you can say that each card costs about 17 c

10x=y
2x+y=-24
Answers
Answer: x=-2
Y= -20
Step-by-step explanation
You replace the y in the second equation with 10x. This is because it says 10x=y
2x+10x=12x so you put that
12x=-24
To get x by its self you divide by 12.
-24 divided by 12 is -2.
Now you plug in -2 to either equation as y. I chose the first one because it's easier.
10(-2)=y
-20=y

Answer:

Step-by-step explanation:
First we have to see how the pattern is increasing.
How did the sequence of numbers get from -3 to 6?
Try adding first.
To get from -3 to 6, add 9.
Move on to the next nunber.
Can we get from 6 to -12 through the same pattern (adding 9)?
No, so addition is not the pattern.
Next try multiplication.
To get from -3 to 6, multiply -2.
Move on to the next number.
Can we get from 6 to -12 through the same pattern (multiplying by -2)?
Yes!
Check the other numbers.
-12 × -2 = 24
24 × -2 = -48
Do they meet the pattern?
Yes!
To find the next number in the sequence, use the pattern: multiply the previous number by -2.
-48 × -2 = 96

QUESTION 6 of 10: You expect your expenses to grow non-linearly over time by the following formula: expenses = 4,000 + 20,000 x (1.5)
where t is the number of months in business. What are your estimated expenses after 6 months ?
a) $231,813
b) $242,131
c) $277,961
d) $282,918
Answers
Answer:
$231,813
Step-by-step explanation:
The estimated expenses after 6 months is $231,812.5
What is Function?In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.
Given:
Expense = 4,000 + 20,000 x [tex](1.5)^t[/tex]
Now, for t= 6 months
Expense = 4,000 + 20,000 x [tex](1.5)^6[/tex]
Expense = 4,000 + 20,000 x 11.390625
Expense = 4,000 + 2,27,812.5
Expense = 231,812.5
Hence, The estimated expenses after 6 months is $231,812.5.

Given that,
To determine the preimage of the ordered pair of D'(4, -3) by the translation, (x, y) to (x – 8, y+4).
Coordinate, is represented as the values on the x-axis and y-axis of the graph.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Let the ordered pair of the preimage be (x, y)
Now,
according to the question,
x - 8 = 4
