Writing One Variable Algebraic
Expressions
Leslie buys a new pair of sneakers for $43 and several
pairs of laces, I, that cost $6 each. Write an algebraic
expression to represent the total amount she will spend.
Answer:
y = 6l + 43
Step-by-step explanation:
y=mx + b
y = y coordinate
m = slope
x = x coordinate
b = y intercept
The y intercept is when x = 0, so the initial cost before buying the laces, which was the cost of the sneakers
b = 43
The slope is you purchase one pair of laces, it increases by 6 each time
m = 6
The y coordinate will represent the total cost spent
y
The x coordinate will represent the total number of laces purchase and we are told that the variable is l
x = l
combine:
y = 6l + 43

Answer:
S = 40 square inches
Step-by-step explanation:
Surface area = area of base + area of lateral faces
Area of the base (square):
A = lw
A = 4(4)
A = 16
Area of lateral faces (triangle and there are 4 of them):
A = bh/2
A = 3(4)/2
A = 12/2
A = 6
Since there are 4 lateral faces, multiply the area by 4.
6 x 4 = 24
Surface area = 16 + 24
S = 40 square inches

HELP ASAP Calculate the residuals for your scatterplot in step 2d.
Create a residual plot for your data. graph is below
The residuals of the linear regression equation are -1.36, 0.32, 0.01, 0.62, 0.17, -0.24, 0.89, 0.09, 0.18 and -0.7
How to determine the residuals?The regression equation is given as:
y = 0.141x + 0.842
Next, we calculate the predicted values (y) at the corresponding x values.
So, we have:
y = 0.141 * 13.8 + 0.842 = 2.78
y = 0.141 * 18 + 0.842 = 3.38
y = 0.141 * 16.7 + 0.842 = 3.20
y = 0.141 * 18 + 0.842 = 3.38
y = 0.141 * 0.7 + 0.842 = 0.94
y = 0.141 * 21.9 + 0.842 = 3.93
y = 0.141 * 15.5 + 0.842 = 3.03
y = 0.141 * 9.2 + 0.842 = 2.14
y = 0.141 * 19.5 + 0.842 = 3.59
y = 0.141 * 16.7 + 0.842 = 3.20
The residuals are then calculated using:
Residual = Actual value - Predicted value
So, we have:
Residual = 1.42 - 2.78 = -1.36
Residual = 3.7 - 3.38 = 0.32
Residual = 3.21 - 3.20 = 0.01
Residual = 4 - 3.38 = 0.62
Residual = 1.11 - 0.94 = 0.17
Residual = 3.69 - 3.93 = -0.24
Residual = 3.92 - 3.03 = 0.89
Residual = 2.23 - 2.14 = 0.09
Residual = 3.77 - 3.59 = 0.18
Residual = 2.5 - 3.20 = -0.7
Hence, the residuals of the linear regression equation are -1.36, 0.32, 0.01, 0.62, 0.17, -0.24, 0.89, 0.09, 0.18 and -0.7

Why do test makers refer to the first term in a sequence as a sub zero sometimes as opposed to a sub 1?
The first term in a sequence is sometimes referred to as [tex]a_0[/tex] as opposed to [tex]a_1[/tex] because [tex]a_0[/tex] represents the initial value
How to explain the sequence statement?The question refers to the difference between the terms
[tex]a_o[/tex] and [tex]a_1[/tex]
The terms in a sequence are represented by a subscript number.
Take for instance a₂ or T₂ represents the second term.
However, when the first term is represented by a₀ instead of a₁.
It means that the sequence has an initial value, other than the first term.
Even though the words "first" and "initial" are synonyms, they do not entirely represent the same thing.
Take for instance, a₀ can be used instead of a₁ in the following scenario
The population of a country is 1000 in 1996 and The country experiences an increment of 250 people every year after 1996.
The above means that:
a₀ = 1000 --- the initial year
a₁ = 1000 + 250 = 1250 ---- the first year after 1996 (i.e. 1997)

Answer:
Construct a circle first
Step-by-step explanation:
If you're going to inscribe any figure in a circle, the first construction you need to do is construct the circle.
__
Additional comment
The attached shows our construction of an inscribed square and an inscribed regular hexagon. Here are the steps we used. You will notice the first step is construct a circle. (It could be, construct line AB, then construct circle A with radius AB.)
We have used line AB in the construction of the hexagon, but the hexagon could have been constructed without it. That is why "construct a circle first" is likely a better choice for a common first step.

Label intersection points K and L.using C as a center, draw arc JM. Label intersection points J and M.draw inscribed hexagon CJKBLM__
Arguably, the first step to constructing a circle is set the compass to the radius. We chose to ignore this because one of the ways to construct an inscribed hexagon is to mark off successive arcs around a circle that have a radius equal to the radius of the circle. We did not use that method. (The use of diameter BC made drawing 5 arcs around the circle unnecessary. We drew 2 instead.)
Or, you could argue that construct a line first is needed before you set the compass to the radius. If this is the first step, then the next steps would be to mark the center of the circle on the line, and mark another point at a distance of the radius from that center point.
What you consider to be the first step depends on the level of detail you want to attend to.

Using data from 1996 to 1998, the annual number of cars sold at a certain dealership can be modeled by the formula y = 4x + 2. Where y is the number of cars in thousands sold x years after 1996. According to this form line in which years will be the number of car sold exceed 46,000
The year, where the number of cars sold exceed 46,000 is 13496
How to determine the year?The equation of the function is given as:
y = 4x + 2
When the sales exceed 46000;
It means that y > 46000
So, we have:
4x + 2 > 46000
Subtract 2 from both sides
4x > 45998
Divide both sides by 4
x > 11499.5
The year is then calculated as:
Year = 1996 + x
So, we have:
Year > 1996 + 11499.5
Evaluate
Year > 13495.5
Approximate
y > 13496

What is a circle?A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.
In order to solve the problem, we need to draw a line segment AB. Since A is the center of the circle AC and AC both will be the radius of the triangle ΔABC. Since two sides of the triangle are equal, the measure of ∠ABC and ∠ACB will be equal therefore, we can write,
∠ACB + ∠ABC + ∠BAC = 180°
2∠ACB + 80° = 180°
∠ACB = 50°

please makes me a brainlest
The Maxair amusement park ride consists of a circular ring that holds 50 riders. Suppose that the center of the ride is at the origin and that one of the riders on the circular ring is at (16, 15.1). If one unit on the coordinate plane equals 1 foot, give an approximation of the circumference of the ride to the nearest foot.
The approximation of the circumference of the ride is 138 feet to the nearest foot
How to determine the circumference?The given parameters are:
Center (a,b) = (0,0) i.e. the originA circular ring, (x,y) = (16,15.1)The radius is calculated using:
[tex]r = \sqrt{(x - a)^2 + (y -b)^2}[/tex]
So, we have:
[tex]r = \sqrt{(16 - 0)^2 + (15.1 -0)^2}[/tex]
Evaluate
r = √484.01
Evaluate the square root
r = 22.0
The circumference is calculated using
C = 2πr
So, we have:
C = 2π * 22.0
Evaluate
C = 138
Hence, the approximation of the circumference of the ride to the nearest foot is 138 feet
