If you were to teach a friend how to solve the following two-step equation : 3x + 18 = 48, what would you say, step by step? You may work it out first before you start your writing.
Answer:
Step-by-step explanation:
3x + 18 = 48
Bringing like terms on one side
3x = 48 - 18
3x = 30
x = 30/10
x = 3
Answer:
x = 10
Step-by-step explanation:
Subtract 18 from both sides.
3x=48-18
Simplify 48-18 to 30.
3x=30
Divide both sides by 3.
x= 30/3
Simplify 30/3\ to 10
x=10
x=10
Determine the equation of the tangent to x− 3x +1 at the point (3,1)
9514 1404 393
Answer:
y = 3x -8
Step-by-step explanation:
We assume you want the tangent to the parabola y = x² -3x +1 at the given point. The slope is found using the derivative of the function at that point.
y' = 2x -3
At x=3, the slope is ...
y' = 2(3) -3 = 3
The equation of the line through point (3, 1) with a slope of 3 is ...
y -1 = 3(x -3) . . . . use the point-slope form of the equation for a line
y = 3x -9 +1 . . . . . eliminate parentheses, add 1
y = 3x -8

Answer: [tex](x,y) \to (4x,4y)[/tex] which is choice (3)
======================================================
Explanation:
The general transformation of [tex](x,y) \to (kx,ky)[/tex] describes a dilation with scale factor k. If k is not equal to 1, then the resulting image will not be the same size as the preimage.
In this case, k = 4. This means that the resulting image has its side lengths 4 times greater compared to the preimage side lengths. For example, if a side length is 5 units long in the preimage, then its corresponding length in the image is 5*4 = 20 units long.
If this is enlargement applied to all sides, then the perimeter also goes up by the same scale factor (since the perimeter is the sum of all exterior sides). The image perimeter will be four times that of the preimage perimeter.
In summary, if you apply a dilation (where k is not equal to 1), then the perimeter will change. If k > 1, then the perimeter gets larger. If 0 < k < 1, then the perimeter will shrink.

Extra info:
Choice (1) describes a reflection over the line y = xChoice (2) is a reflection over the x axis.Choice (4) describes a translation of 2 units to the right and 5 units down.The transformations of reflections, translations, and rotations all are considered rigid transformations. This means that they keep the same size and shape. You can imagine the camera is moving around in some way and the shapes stay still (but give the illusion of movement). In other words, rigid transformations will keep the perimeter the same. Because of this, we can rule out choices (1), (2) and (4).Which statement CANNOT be represented by the expression t - 16

Find the slope given the points (2, −7) and (−1, 6).
Answer:
The slope would be 13/-3 or -4.3... repeating
Step-by-step explanation:
The slope of the line passing through the points (2, −7) and (−1, 6) is (13 / 3 ).
What is the slope of the line?Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line.
The slope of the line is calculated by the formula below,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given points through which the line is passing are (2, −7) and (−1, 6). The slope of the line is calculated by the formula written below,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope = (6 - ( - 7 ) / ( -1 - 2 )
Slope = 13 / - 3
Slope = -13 / 3
Therefore, the slope of the line passing through the points (2, −7) and (−1, 6) is (13 / 3 ).

Answer:
A. f(x) = (x -3)² -1
B. vertex: (3, -1); axis of symmetry: x=3; x-intercepts: {2, 4}; y-intercept: 8
C. see attached for a graph
Step-by-step explanation:
A. Put the function in vertex form by completing the square. Start by putting parentheses around the terms containing x.
f(x) = (x² -6x) +8
Now, identify the coefficient of x (-6) and square half of that. (-6/2)² = 9. Add this value inside parentheses, and subtract this value outside parentheses.
f(x) = (x² -6x +9) +8 -9
Rewrite the trinomial in parentheses as a square. The constant in the binomial will be the value you squared in the previous step.
f(x) = (x -3)² -1 . . . . . vertex form; a(x -h)²+k for vertex (h, k)
__
B. The vertex and the axis of symmetry can be read from the equation. Here, the vertex is (3, -1). The axis of symmetry is the vertical line through the vertex: x = 3. The x-intercepts are found by solving f(x) = 0.
f(x) = 0
(x -3)² -1 = 0
(x -3)² = 1 . . . . . add the opposite of the 'k' value
x -3 = ±√1 . . . . take the square root. We need both signs.
x = 3 ± 1 . . . . . add 3 to get x by itself. These are the x-intercepts.
x = 3-1 = 2 and x = 3+1 = 4
The x-intercepts are 2 and 4, points (2, 0) and (4, 0).
The y-intercept is the value of f(0). It is the constant in the original form of the function. f(0) = 8 . . . . y-intercept

C. The graph is attached. The various points above are marked, and the axis of symmetry is shown.

What is the additive inverse of the polynomial –9xy2 + 6x2y – 5x3?
Answer:
f'(x) = -f(x) = 9xy² - 6x²y + 5x³
Step-by-step explanation:
f(x) = –9xy² + 6x²y – 5x³
additive inverse: f'(x) = -f(x) = 9xy² - 6x²y + 5x³
f(x) + f'(x) = f(x) -f(x) = (–9xy² + 6x²y – 5x³) + (9xy² - 6x²y + 5x³) = 0

The space probe Voyager I travels 3.255 x 108 miles in a year.
At this rate, how far does the Voyager I travel during a period of 40 years?
The Voyager I travel 130.2 x [tex]10^8[/tex] miles during a period of 40 years.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
The space probe Voyager I travels 3.255 x [tex]10^8[/tex] miles in a year.
So, in 40 years Voyager I travel
= 3.255 x [tex]10^8[/tex] x 40
= 130.2 x [tex]10^8[/tex] miles.
Thus, the Voyager I travel 130.2 x [tex]10^8[/tex] miles.

Katherine's bakery expects to sell 20 Bundt cakes every 5 days. Based on this information, how many days does the bakery expect that it will take to sell 44 Bundt cakes?
Answer:
the number of days taken is 11
Step-by-step explanation:
The computation of the number of days expected to sell 44 bundt cakes as follows:
Given that
It takes every 5 days to sell 20 bundt cakes
So for 44 bundt cakes it would take
= 44 × 5 days ÷ 20
= 11 days
hence, the number of days taken is 11
