what is the linear equation that has a y-intercept of -4 and a x-intercept of -5
The linear equation that has a y-intercept of -4 and a x-intercept of -5 s y = -4/5x - 4
Equation of a lineThe equation of a line in slope intercept form is expressed y = mx + b
where
m is the slope
b is the y-intercept
Given the coordinate points (0, -4) and (-5, 0), the slope is calculated as:
Slope = y₂-y₁/x₂-x₁
Slope = 4/-5
Slope = -4/5
Determine the equation
y = -4/5x + (-4)
y = -4/5x - 4
Hence the linear equation that has a y-intercept of -4 and a x-intercept of -5 s y = -4/5x - 4

A garden store Sells bags of potting soil in flats. There are 7 Bags in each flat . each palette has 7 flats the garden store sold 17 pallets on Saturday and 23 How many bags of potting soil did the gardner sell in all ?
The garden store was able to sell a total of 1,960 bags of potting soil on Saturday and Sunday.
What is distributive property of multiplication over addition ?
If we multiply a number by the sum of more than two, we use the distributive property of multiplication over addition.
In order to find the number of bags of potting soil sold over those two days, the first step is find out the number of pallets store sold there potting soil :
= 17( on Saturday) + 23 (Sunday)
= 40 palettes
Each palettes has 7 flats so the total number of flats sold is:
= 40 x 7
= 280 flats
Each flat then contains 7 bags so the total number of bags sold is:
= Number of flats sold x 7
= 280 x 7
= 1960 bags
In conclusion 1,960 bags of potting soil were sold.

Ellen's living room is 5 meters wide and 7 meters long. She wants to install indigo carpet that costs $10.00 per square meter. How much will it cost to buy enough carpet for the living room?
It will cost $350.00 to buy enough carpet for the living room.
What is an area?Area is the quantity that expresses the extent of a region on the plane or on a curved surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of the three-dimensional object.
Now it is given that,
Length of room,l =
Width of room, w =
So, area of the room = l*w = 7*5
⇒ area of the room = 35 square meter
Since, indigo carpet costs $10.00 per square meter
Thus, total cost to install the carpet = area of the room*carpet costs
⇒ total cost to install the carpet = 35*10
⇒ total cost to install the carpet = $350
Thus, It will cost $350.00 to buy enough carpet for the living room.

Answer:
tₙ = n² + n + 13=============================
Given sequence:
15, 19, 25, 33, 43, ...We can see this not AP or GP as the difference or ratio of consecutive terms is not common.
But we can see the difference between terms has common difference of 2:
19 - 15 = 425 - 19 = 633 - 25 = 843 - 33 = 10and
10 - 8 = 28 - 6 = 26 - 4 = 2It means the sequence is of the second degree, in other words it is quadratic.
In general it is of the form:
tₙ = an² + bn + c, where a, b, c are coefficients, n - is the number of the terms.Use the terms of the given sequence to work out unknown coefficients.
t₀ = 15 - (4 - 2) = 15 - 2 = 13
a(0)² + b(0) + c = 13c = 13It gave us the value of c.
t₁ = 15
a(1)² + b(1) + c = 15a + b + c = 15a + b + 13 = 15a + b = 2t₂ = 19
a(2)² + b(2) + c = 194a + 2b + c = 194a + 2b + 13 = 194a + 2b = 6Compare the last two equations and solve for a and b:
a = 2 - b4(2 - b) + 2b = 68 - 4b + 2b = 62b = 8 - 62b = 2b = 1Then
a = 2 - 1 a = 1So we know the coefficients:

9-3-3-3 = 0 written as a division problem
The value of 9-3-3-3=0 written as division problem is the value of 0.333
According to the Honor algebra:
The symbols for variables used in algebra, which may be found in Greek and Latin literature, can be used to date the creation of algebra to the height of Greek or Latin culture.
9-3-3-3=0 as written as division
⇒ 9÷3÷3÷3 =0
⇒ 9÷3 =3÷3
⇒ 3=1
⇒ x=1/3
⇒ x=0.333
so, the value of 9 divide by 3 and divided by 3 equals to 3 divvied by 3 is the value of 0.333.
When things are more realistic, algebra becomes much more intriguing. With a two-pan balance, some mystery bags, and a ton of jelly beans, solving linear equations is much more enjoyable.
Therefore, the 9-3-3-3=0 written as division is the value of 0.333.

Answer:
f(3) = 3 - 3 --> f(3) = 0
f(x) = 12, x = 15 (because 15 - 3 would equal 12)
g(-3) = 2 (because in the chart for g(x), an x of -3 is 2)
g(x) = -3, x = 5 (because in the chart for g(x), a g(x) of -3 is an x of 5)
For the graph questions, p(0)= means that the 0 is the x integer and you must find the y when x=0
p(0) = 3
p(-4) = 5
p(1) = 3
p(x) = 1, x = 2
For the graph questions, p(x)=0 means that the 0 is the y integer and you must find the x when y=0

Employees in 2012 paid 4.2% of their gross wages towards social security (FICA tax), while employers paid another 6.2%. How much will someone earning $39,000 a year pay towards social security out of their gross wages?
Someone who is earning $39,000 a year, would pay $1,638 towards social security out of their gross wages
Employees in 2012 paid 4.2% of their gross wages towards social security tax.
As the gross yearly wages of an employee is $39,000 and he have to pay the 4.2% of his gross wages towards social security or FICA tax.
Percentage means division by 100 and to know the contribution of the employee we need to multiply the percentage with the gross wages of the employee
He paid towards social security = 4.2% of 39000
= 4.2/100×39000
= 0.042 × 39000

Complementary Angles- When the sum of two angles is equal to 90 degrees, they are called complementary angles. (For example, 30 degrees and 60 degrees are complementary angles)
Supplementary Angles-Supplementary angles are those angles that sum up to 180 degrees. (For example, angle 130° and angle 50° are supplementary angles because sum of 130° and 50° is equal to 180°.)
Congruence Postulate- to be congruent if two angles and the side between these two angles of one triangle are congruent to corresponding angles and the included side (side between two angles) of the other triangle
Linear Pairs of Angles-A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.

During an experiment, the temperature of a mixture changes from 12 1/4°F to 15 3/5°F. What is the percent of the increase in the temperature of the mixture? I need an answer to the as a percent rounded to the nearest hundredth.
During the experiment the temperature changes slightly. Hence
the percentage increase in the temperature of the mixture is 27.35%.
Given, the temperature of the mixture changes from 12 1/4°F to 15 3/5°F
we are asked to determine the percentage of increase in the temperature of the mixture.
Initial temperature = 12 1/4°F
convert it into proper fraction.
= 48+1/4
= 49/4°F
Final temperature = 15 3/5°F
convert it into proper fraction.
= 75+3/5
= 78/5
Therefore, percentage increase:
= Final temp - Initial temp/Initial temp × 100
% Increase = (78/5 - 49/4)/49/4 × 100
% Increase = (78×4 - 49×5/5×4)/49/4 × 100
% Increase = 312-245/5×49 × 100
as 4 gets cancelled from numerator and denominator.
% Increase = 67×100/249
% Increase = 6700/249
% Increase = 27.346%
we need to round it off to the nearest hundredth.
% Increase = 27.35%
Hence the percentage increase in the temperature is 27.35%.

The area of the composite figure whose vertices have the (2,-2), (2,1), (4,2), (6,2), (4,-1) coordinates is 6 square units
We first need to plot all the given points A (2,-2), B (2,1), C (4,2), D (6,2)and E (4,-1) which is coordinate geometry
After joining the Points which is a pentagon and it can be divided in two shapes one is triangle CDE and a quadrilateral ABCE
Using the distance formula
BC = [tex]\sqrt{(y2-y1)^{2}+(x2-x1)^{2} }[/tex] = [tex]\sqrt{(2-1)^{2} + (4-2^{2} }[/tex] = √5
Since BC = AE and BC ll AE , we can say ABCE is a parallelogram

Area of triangle CDE where CD is perpendicular and CE is the base

So the area of ABCDE = Area of ABCE + area of CDE

The average rate of change in the fuel economy in the interval of speed [60,80] is 0.1
The given function F(x) = −0.005x 2 + 0.8x + 12 models the relationship between a certain vehicle’s speed and the fuel economy
where F(x)= fuel economy in kmpl
x =speed of the vehicle in km/h
we need to find the average rate of change in the fuel economy in the interval of speed [60,80].
At speed 60 km/h
the fuel economy = - 0.005(60²) + 0.8(60) +12

At speed 80 km/h
the fuel economy = - 0.005(80²) + 0.8(80) +12
