What is a linear equation?A linear equation is in the form:
y = mx + b
Where y, x are variables, m is the rate of change and b is the y intercept.
Let y represent the amount of water in gallon after x hours.
The y intercept is (0, 175), hence b = 175.
The line passes through (0, 175) and (7, 0), hence::
Slope = (0 - 175) / (7 - 0) = -25
The equation is y = -25x + 175

Me podrian ayudar con ese ejercisio por favor?? Me salvarian 4. Dadas las sucesiones de término general an = n + 3 y bn = 5n − 1 , realiza las siguientes operaciones: a) an – bn b) an + 3bn 5. Escribe los ocho primeros términos de la sucesión ( an ) dada por: a1 = 1, a2 = 1, an = an−1 + an−2
Explicación paso a paso:
Dado
an = n + 3
bn = 5n-1
a) an-bn = n + 3- (5n-1)
= n + 3-5n + 1
= n-5n + 3 + 1
= -4n + 4
an-bn = 4-4n
b) an + 3bn = (n + 3) +3 (5n-1)
= n + 3 + 3 (5n) +3 (-1)
= n + 3 + 15n-3
= n + 15n + 3-3
= 16n + 0
= 16n
an + 3bn = 16n
3) Dado a1 = 1, a2 = 1
an = an-1 + an-2
Debemos escribir los primeros ocho términos de la secuencia.
a3 = a3-1 + a3-2
a3 = a2 + a1
a3 = 1 + 1
a3 = 2
a4 = a3 + a2
a4 = 2 + 1
a4 = 3
a5 = a4 + a3
a5 = 3 + 2
a5 = 5
a6 = a5 + a4
a6 = 5 + 3
a6 = 8
a7 = a6-a5
a7 = 8 + 5
a7 = 13
a8 = a7 + a6
a8 = 13 + 8
a8 = 21
Por tanto, los primeros ocho términos de la secuencia son 1, 1, 2, 3, 5, 8, 13 y 21

2.x=2
3.x = -2
Answer:
The correct answer is x=2
Step-by-step explanation:
The equation of the given line written in slope-intercept form is y=x-2.
From the given figure, x-intercept of 2.
What is the slope intercept form?The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept.
The standard form of the slope intercept form is y=mx+c.
Here, slope is 0
Substitute (x, y)=(2, 0) and m=1 in y=mx+c, we get
0=1(2)+c
c=-2
Put m=1 and c=-2 in y=mx+c, we get
y=x(1)-2
⇒y=x-2
Therefore, the equation of the given line written in slope-intercept form is y=x-2.

(fºg)(-5).
Answer:
3 i think
Step-by-step explanation:
so we substitute -5 to g(x)
g(x) = -4(-5) + 3
= 20 + 3
= 23
now we substitute it to f(x)
f(x) = -2x + 49
= -2(23) + 49
= -46 + 49
= 3
Answer:
3
Step-by-step explanation:
f(x) = -2x + 49
g(x) = -4x + 3
(fºg)(x) = f(g(x)) = -2(-4x + 3) + 49
(fºg)(x) = 8x - 6 + 49
(fºg)(x) = 8x + 43
(fºg)(-5) = 8(-5) + 43

Step-by-step explanation:
Given :-

Area (painted) = Area (wall) - Area (window)Area (painted) = 10 x 11 - 2 x 3110 - 6104 ft²A golf ball was hit and modeled by
-16x2 + 11x + 6 = 0
When will the golf ball hit the ground?
Round to the nearest hundreths
By using the quadratic formula, we can conclude that the golf ball will hit the ground at x = 0.5 seconds.
What is the quadratic formula?
The quadratic formula is a formula that gives the solutions of a quadratic equation in the form [tex]ax^2 + bx + c = 0[/tex], where a, b, and c are constants and x is the variable. The formula is:
x = (-b ± [tex]\sqrt{b^2 - 4ac}[/tex]) / 2a
This formula can be used to find the values of x that satisfy the quadratic equation.
To find when the golf ball will hit the ground, we need to find the value of x when the height of the golf ball is equal to zero. We can do this by solving the quadratic equation [tex]-16x^2 + 11x + 6 = 0[/tex] using the quadratic formula:
x = (-b ± [tex]\sqrt{b^2 - 4ac}[/tex]) / 2a
where a = -16, b = 11, and c = 6. Substituting these values, we get:
x = (-11 ± [tex]\sqrt{11^2 - 4(-16)(6)}[/tex] ) / 2(-16)
x = (-11 ± [tex]\sqrt{361}[/tex])/ (-32)
Simplifying this expression, we get:
x = (-11 ± 19) / (-32)
So the two possible values of x are:
x = 8/16 = 0.5 and x = 30/16 = 1.88
Since the height of the golf ball is equal to zero when it hits the ground, we can conclude that the golf ball will hit the ground at x = 0.5 seconds (rounded to the nearest hundredth).

The first term of a sequence is 2, the third term is 18, and the fifth term is 162. What is
the second term of the sequence?
Answer:
[tex]a_2=6[/tex]
Step-by-step explanation:
Geometric sequence general formula: [tex]a_n=ar^{n-1}[/tex]
Given:
[tex]a_1=2[/tex][tex]a_3=18[/tex][tex]a_5=162[/tex]Therefore,
[tex]a_1=2 \implies a=2[/tex]
[tex]a_3=2 \cdot r^2=18[/tex]
[tex]a_5=2 \cdot r^4=162[/tex]
To find common ratio r, divide 5th and 3rd terms:
[tex]\dfrac{a_5}{a_3}=\dfrac{2 \cdot r^4}{2 \cdot r^2}=\dfrac{162}{18}[/tex]
[tex]\implies r^2=9[/tex]
[tex]\implies r=\sqrt{9}=3[/tex]
Therefore, geometric sequence formula: [tex]a_n=2 \cdot 9^{n-1}[/tex]
So second term of sequence:
[tex]\implies a_2=2 \cdot 3^{2-1}=6[/tex]
Use distributive property to factor method 1. Use distributive property to expand method 2.
Step-by-step explanation:
I guess method 1 means to deal with whole factors.
x + 5 = (x - 2)(x + 5)
for (x + 5) <> 0 we can divide both sides by this factor :
1 = x - 2
x = 3
for the second solution we deal with
x + 5 = 0
x = -5
so, for x = -5 and x = 3 both functions deliver the same output, and these are the intersection points.
method 2 : we multiply the expression out and solve it then
x + 5 = (x - 2)(x + 5)
x + 5 = x² + 5x - 2x - 10 = x² + 3x - 10
0 = x² + 2x - 15
the general solution to such a square equation is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
a = 1
b = 2
c = -15
x = (-2 ± sqrt(2² - 4×1×-15))/(2×1) =
= (-2 ± sqrt(4 + 60))/2 = (-2 ± sqrt(64))/2 = (-2 ± 8)/2 =
= -1 ± 4
x1 = -1 + 4 = 3
x2 = -1 - 4 = -5
and you get the 2 solutions again. as expected, they are the same as with method 1, of course.

ou are buying batteries, a stereo, and some CDs from the I.B. Electronics store. You can buy from this store online or in a physical store. You have a coupon for 10% off that can only be used in the physical store and a $5.00 off coupon that can only be used online. The sales tax of 5% only applies to the physical store. Shipping for the online store is a flat rate of $6.99. You are trying to decide whether to shop at the physical store or the online store.

CDs 3 CDs $7.95/CD $8.95/CD
There is not enough information given.
It would cost less to purchase the items from the physical store.
It would cost less to purchase the items from the online store.
Answer:
It would be cheaper to use the online store
Step-by-step explanation:
the physical store added up to $129.04 and the online store was $128.82.
It would cost less to purchase the items from the physical store.
The correct option is C.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. Moreover, it is indicated by the symbol "%."
To calculate the total cost for each store, we need to take into account the discounts, taxes, and shipping fees.
For the physical store:
Batteries: 2 packs x $5.99/pack = $11.98
Stereo: 1 system x $100.00/system = $100.00
CDs: 3 CDs x $7.95/CD = $23.85
Subtotal: $135.83
After the 10% discount: $135.83 - 10% = $122.25
Sales tax: $122.25 x 5% = $6.11
Total cost: $122.25 + $6.11 = $128.36
For the online store:
Batteries: 2 packs x $4.99/pack = $9.98
Stereo: 1 system x $90.00/system = $90.00
CDs: 3 CDs x $8.95/CD = $26.85
Subtotal: $126.83
After the $5.00 discount: $126.83 - $5.00 = $121.83
Shipping fee: $6.99
Total cost: $121.83 + $6.99 = $128.82
Therefore, it would cost less to purchase the items from the physical store.

To say that two or more angles are equal, we draw a little arc. If there are two arcs then it means that the angle with also two arcs marked is equal in measure, and so on
--> so:
∠A ≅ ∠Y
∠B ≅ ∠Z
∠C ≅ ∠X
To say that two more sides are equal, we draw a little tic mark. If there are two tics then it means that the sides with also two tics marked are equal in length, and so on.
--> so:
AB ≅ YZ
AC ≅ YX
BC ≅ ZX
And thus ΔACB ≅ ΔYXZ <-- we got this by matching corresponding angles of equal length

Answer: Approximately 8.5 units
Step-by-step explanation:
Substitute M(2, -2) and N(8, 4) for the coordinates in the distance formula and solve for d
[tex]d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }[/tex]
[tex]d = \sqrt {\left( {8-2 } \right)^2 + \left( {4-(-2)} \right)^2 }[/tex]
[tex]d = \sqrt {\left( {6 } \right)^2 + \left( {6} \right)^2 }[/tex]
[tex]d = \sqrt {\left( {36 } \right) + \left( {36} \right) }[/tex]
[tex]d = \sqrt {72}[/tex]
[tex]d \approx 8.5\hspace2 units[/tex]
