what is y=5(x-4)+5 in slope intercept form
Answer:
y= 5x-20+5
y=5x-15
so slope is 5
intercept is -15
Answer:
y=5x -15
Step-by-step explanation:
y=5(x-4) +5 -> y= 5x -20 +5 -> combine to get y=5x-15
A group of 83 students are visiting the National Aquarium in Baltimore. Volunteers lead tours for groups no larger than 5 students at a time. How many tour guides are needed so all 83 students are able to participate in a guided tour of the aquarium
Answer:
17 tour guides
Step-by-step explanation:
First, we need to divide 83 by 5.
83 ÷ 5 = 16 R 3As you can see, there are 16 tour guides that can handle 5 students each. However, there are a remainder of 3 students, so we need one extra tour guide. Thus, the answer is 17 tour guides.
Answer:
They need 17 tour guides
Step-by-step explanation:
If we divide 83 by 5, we would get 16.6, and since we can't have 16.6 tour guides, we round to the nearest whole number, which is 17.
To order for all students to participate, they would need 17 tour guides.

Is the Answer A, B, C, or D?
Answer:
A. [tex]f(x)=451(0.68)^x[/tex]
Step-by-step explanation:
Function [tex]f(x)=451(0.68)^x[/tex] best models the given data.
Which equation is represented by the model? x2 – 2x – 3 = (x – 3)(x 1) x2 – 4x 3 = (x – 3)(x – 1) x2 2x 3 = (x 3)(x – 1) x2 4x – 3 = (x 3)(x 1).
The equation which can be represented by the algebraic model are provided in option A and option B as,
[tex]x^2 - 2x - 3 = (x - 3)(x +1)[/tex]
[tex]x^2 - 4x+ 3 = (x - 3)(x - 1)[/tex]
What is algebraic model?Algebraic model are the expression which consist the variables, coefficients of variables and constants.
The algebraic model are used represent the general problem in the mathematical way to solve them.
Let's check the first option,
[tex]x^2 - 2x - 3 = (x - 3)(x +1)[/tex]
Multiply the brackets to solve it further as,
[tex]x^2 - 2x - 3 = x^2+x-3x-3\\x^2 - 2x - 3 = x^2-2x-3[/tex]
As, the LHS is equal to the RHS. Thus, this is correct option.
Second option is given as,
[tex]x^2 - 4x+ 3 = (x - 3)(x - 1)[/tex]
Multiply the brackets to solve it further as,
[tex]x^2 - 4x+ 3 = x^2 -x-3x+3\\x^2 - 4x+ 3 = x^2 -4x+3[/tex]
As, the LHS is equal to the RHS. Thus, this is correct option.
Third option is given as,
[tex]x^2 +2x+ 3 = (x +3)(x - 1)[/tex]
Multiply the brackets to solve it further as,
[tex]x^2 +2x+ 3 = x^2 -x+3x - 3 \\x^2 +2x+ 3 = x^2 +2x - 3[/tex]
As, the LHS is not equal to the RHS. Thus, this is not correct option.
Forth option is given as,
[tex]x^2 +4x - 3 = (x+ 3)(x +1)[/tex]
Multiply the brackets to solve it further as,
[tex]x^2 +4x - 3 = x^2+ x+3x +3\\x^2 +4x - 3 = x^2+4x +3[/tex]
As, the LHS is not equal to the RHS. Thus, this is not correct option.
Hence, the equation which can be represented by the algebraic model are provided in option A and option B as,
[tex]x^2 - 2x - 3 = (x - 3)(x +1)[/tex]
[tex]x^2 - 4x+ 3 = (x - 3)(x - 1)[/tex]

7 pencils cost £5.95.
How much do 11 pencils cost?
Answer:
11 pencils cost £9.35.
Step-by-step explanation:
Given;
7 pencils = £5.95
1 pencil = 5.95 ÷ 7
= £0.85
Now,
11 pencils = 11 × 0.85
= £9.35
Answer:
9.35$
Step-by-step explanation:
to find the cost of 11 pencils first we need to find the price of 1.
5.95 divided by 7 = 0.85$ (the price of one pencil)
we need to find the price of 11 pencils though.
0.85x11= 9.35$

What two numbers multiply to get -36 and add to get 5
Adam is saving money to buy a new computer that costs $550. His mom has given him $100 to begin. Each week, he deposits money into his savings account. The table shows the balance after t weeks. Time (t) in weeks 0 1 2 3 4 Balance (b) $100 $125 $150 $175 $200 Write an equation to represent this situation.
Answer:
25t + 100 = 550
Step-by-step explanation:
Notice that for every week, the balance increases by $25. That means t will be multiplied by 25 like this: 25t
There is already $100 on top of that, so add 100 to it like this: 25t + 100
Since Adam is saving for a $550 computer, this sum has to equal 550
25t + 100 = 550
If you want to find out how many weeks it will take to get that computer, subtract 100 from both sides
25t + 100 = 550
- 100 - 100
25t = 450
Divide both sides by 25
25t/25 = 450/25
t = 18
It will take Adam 18 weeks to save up and buy that computer.

The 14 compact cars sold by a dealer on Monday was 56% of the cars sold that day.
step by step please
the 14 cars sold = 56% of total car stock
how many cars (noted n) for 100 % ?
14.............56%
n..............100%
n x 56% = 14 x 100%
n = 14 : 0,56
n = 25
total cars in stock : 25
56% were sold
so 25 x 56% = 14 have been sold

Answer:
9x² + 24xy + 16y²
Step-by-step explanation:
(3x + 4y)²
= (3x + 4y)(3x + 4y)
each term in the second factor is multiplied by each term in the first factor.
3x(3x + 4y) + 4y(3x + 4y) ← distribute both parenthesis
= 9x² + 12xy + 12xy + 16y² ← collect like terms
= 9x² + 24xy + 16y²

Write an equation of the parabola in vertex form that passes through (13,8) and has vertex (3,2).
Answer:
[tex]y=\frac{3}{50} (x-3)^{2}+2[/tex]
Step-by-step explanation:
Vertex: (3,2)
Point: (13,8)
The equation form is [tex]y=a(x-h)^2+k[/tex]
h = 3
k = 2
y = 8
x = 13
Plug in the values into the form..
[tex]8=a(13-3)^{2} +2[/tex]
Simplify and solve for a..
[tex]8=a(10)^{2}+2[/tex]
[tex]8=100a+2[/tex]
[tex]100a=8-2[/tex]
[tex]100a=6[/tex]
[tex]a=\frac{6}{100} or \frac{3}{50}[/tex]
Plug a into the equation..

c is inversely proportional to d.
c=0.5 when d=6
Find a formula for c in terms of d.
I think this is the answer!
c=3/d
The formula for c in terms of d is c= 3/d
What is Constant of proportionality?The ratio between two quantities that are directly proportional is the constant of proportionality. When two quantities grow and shrink at the same rate, they are directly proportional. When y and x are two values that are directly proportional to one another, the proportionality constant k is defined as k=y/x.
Given:
c=0.5 when d=6
We know that c is inversely proportional to d.
c ∝ 1/d
c = k / d
and, k = cd
k = 0.5 x 6
k = 3
Hence, the formula for c in terms of d is c= 3/d

What is the LCM of 600 and 1050?
Thanks :)
Answer:
4200
Step-by-step explanation:
The least common multiple (LCM) is the product of the unique factors of the numbers:
600 = 4 × 150
1050 = 7 × 150
LCM(600, 1050) = 4×150×7 = 4200
_____
The above factoring may also help you see that the LCM is also the product divided by the greatest common factor:
LCM(600, 1050) = 600 × 1050 / GCF(600, 1050)
= 600 × 1050 / 150
= 4200

Step-by-step
Step-by-step explanation:
the rules of the angles of 2 lines intersecting each other.
that means the angles on one side of the first line sind the intersection point, are the same as on the other side of the line - just left-right interchanged.
and to have a third line, parallel to the first line, where the exact same angles have to be, where the second line intersects the third line (a parallel line is like a mirror image of the first line : every look and feel has to be the same).
and then remember : all angles around a single point in one side of a line must be together 180°.
so, if the support beam has an angle of 125° with the top "line", the second angle there (the exterior Angie at that point) is then 180 - 125 = 55°.
this is all at the bottom side of the top "line".
these angles are therefore left-right exchanged the same on the top side of the top "line". so, 55° and 125° instead of 125° and 55°.
these angles at the top of the top "line" must be now exactly the same at the top of the parallel bottom "line" of the truss.
so, the interior angle there is 55°. and the exterior angle is 125°.

If f(x)=x^2+3 and g(x)=2x-5 find (f-g) (x)
Answer:
[tex](f - g)(x) = x^2-2x-2[/tex]
Step-by-step explanation:
We have the following two functions:
[tex]f(x)=x^2 +3g(x) = 2x-5[/tex]
In order to solve for [tex](f - g)(x)[/tex] we look at the two functions and realize that:
[tex](f - g)(x) = f(x) - g(x) = x^2+3-2x-5=x^2-2x-2[/tex]
Therefore:
[tex](f - g)(x) = x^2-2x-2[/tex]
