Answer:
y = 5x +23
Step-by-step explanation
y = mx + b
the gradient ; m = 5 (given)
to find y=int, b, plug in the coordinate into y = mx + b;
3 = 5(-4) + b
3 = -20 + b
b = 23
so, we got y = 5x + 23

Step-by-step explanation:
Damon was on his way to a marble tournament when he met Artemio. Damon's bag of marbles was heavy, so he gave Artemio ½ of his marbles plus 2. Then he met Banou and gave her ¼ of his remaining marbles plus 5. Just before arriving at the tournament, he met Alex and gave him ½ of the marbles he had left. When he got to the tournament, he had 2 marbles left. How many marbles did he start with?
Answer: 28.
Step-by-step explanation:
Let's define D = # of marbles in Damon's bag at the beginning.
First, he gave D/2 + 2 marbles to Artemio, so now he has:
(D - D/2 - 2) = (D/2 - 2) marbles left.
Now, he gives 1/4 plus of what he has left plus 5 to Banou, so he gives:
(D/2 - 2)/4 + 5 marbles to Banou.
Then Damon has now:
(D/2 - 2) - (D/2 - 2)/4 - 5 = 3*(D/2 - 2)/4 - 5.
Now Damon gives half of this to Alex, then the amount that he has left is:
(3*(D/2 - 2)/4 - 5)/2
And we know that this is equal to 2, then we can solve this equation as:
(3*(D/2 - 2)/4 - 5)/2 = 2
Let's solve this for D.
(3*(D/2 - 2)/4 - 5) = 2*2 = 4.
3*(D/2 - 2)/4 = 4 + 5 = 9
3*(D/2 - 2) = 9*4 = 36
(D/2 - 2) = 36/3 = 12
D/2 = 12 + 2 = 14
D = 2*14 = 28
Damon initially had 28 marbles.

pose that the function f(x) - 5.32 +0.80x represents the cost of mailing an
ect that weighs x pounds. How much would it cost to mail an object that
ghs 36 pounds?
te: express the answer in dollars.cents)
Answer:
$34.12Step-by-step explanation:
The expression for the total cost of a mail is given as
f(x) - 5.32 +0.80x, where x is the amount of weight in pounds
Given that x= 36 pounds we can find the cost of mailing 36 pounds of ect
hence let us put x=36 in the expression to find the total cost
f(x) =5.32 +0.80(36)
f(x) =5.32 +28.8
f(x) =34.12
Therefore the cost of mailing 36 pounds of ect is $34.12

The sum of the squares of the two consecutive multiples of 7 is 637. Write the
equation that characterizes this multiples.
Answer:
The first multiple of 7 = 14 or -21
The second multiple of 7 = 21 and -14
Step-by-step explanation:
Let
The first multiple of 7 = 7x
The second multiple of 7 = 7(x+1)
Square of the first multiple = (7x)^2
Square of second multiple = {7(x+1)}^2
Sum
(7x)^2 + 7(x+1)}^2 = 637
49x^2 + 49(x+1)^2 = 637
Divide through by 49
x^2 + (x+1) = 13
Open bracket
x^2 + x^2 + 1 + 2x = 13
Subtract 13 from both sides
x^2 + x^2 + 1 + 2x - 13 = 13 - 13
x^2 + x^2 + 1 + 2x - 13 = 0
2x^2 + 2x - 12 = 0
Divide through by 2
x^2 + x - 6 = 0
Solve the quadratic equation using factorization method
x^2 + 3x - 2x - 6 = 0
x(x+3) - 2(x+3) = 0
(x - 2) (x+3) = 0
x - 2 = 0
x = 2
x+3 = 0
x = -3
Substitute x = 2 or -3 into 7x
When x= 2
7(2) = 14
When x = -3
7(-3) = -21
The first multiple of 7 = 14 or -21
Substitute x = 2 or -3 into 7(x+1)
When x= 2
7(2+1) = 7(3) = 21
When x = -3
7(-3+1) = 7(-2) = -14
The second multiple of 7 = 21 and -14

b,$870
Step-by-step explanation:
a if P=R‒C.(to find R you have to know the opposite of ‒C) ( -C≠C)
then add C in two sides
(P+C=R‒C+C)
(P+C=R)
SO the formula is R=P+C

Whats the domain and range
Answer:
Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

What is an arithmetic sequence?A series of integers called an arithmetic succession or arithmetic chain of events has a fixed difference between the terms.
Let a₁ be the first term and d be a common difference.
Then the nth term of the arithmetic sequence is given as,
aₙ = a₁ + (n - 1)d
The explicit rule for a sequence and one of the specific terms is given.
fₙ = (3n - 3) + 3
If the value of the nth term is 72. Then the position of the term is given as,
72 = (3n - 3) + 3
72 = 3n - 3 + 3
72 = 3n
n = 72 / 3
n = 24
The value of the nth term is 72. Then the position of the nth term will be 24.

6) Maria bought seven boxes. A week later
half of all her boxes were destroyed in a fire.
There are now only 22 boxes left. With
how many did she start?
please helppp
Answer:
37 boxes
Step-by-step explanation:
you should try and write each of the steps into an equation of x. Where x is the boxes she started with
so, she had x boxes, she bought 7 (that's addition) and then half of those boxes (that's division) got destroyed in the fire and she has 22 left (that's your total).
you can write the equation like this:
(x+7)/2 = 22
then, you solve
(x+7) = 44
x = 37
she originally had 37 boxes

3 1/2 as an equivalent fraction with a denominator equal to 12
Answer:
42/12
Step-by-step explanation:
3 1/2 in improper fraction form is 7/2. We can see the denominator in the equivalent fraction is 12. In order for that to happen, the common factor that must have been multiplied is 6. So the numerator of the equivalent fraction should be 42 because:
7 42
___ = ____

First, you must simplify both sides if the equation.
[tex]\frac{7}{2}=\frac{x}{12}[/tex]
Then, multiply both sides by 12
[tex]42=x[/tex]
[tex]x=42[/tex]
Finally, substitute in 42 for x

What is the x-intercept of the graph?
Answer:
see below
Step-by-step explanation:
y= 1/2x - 2
To find the x intercept, set y =0 and solve for x
0= 1/2x - 2
Add 2 to each side
2 = 1/2x -2+2
2 = 1/2x
Multiply by 2
2*2 = 1/2x *2
4 =x
The x intercept is 4
