Answers
We can turn this into words => (x + 7, y - 3).
Our answer is C) (x + 7, y - 3). Hope this helps and have a fantastic day!
Answer: The correct option is (C) (x+7, y−3) .
Step-by-step explanation: We are given to select the correct transformation rule that maps triangle ABC onto triangle DEF.
From the graph, we note that
the co-ordinates of the vertices of triangle ABC are A(-8, 6), B(-3, 6) and C(-7, 4).
And, the co-ordinates of the vertices of triangle DEF are D(-1, 3), E(4, 3) and F(0, 1).
The transformations from the vertices of triangle ABC to the vertices of triangle DEF are
A(-8, 6) → D(-1, 3) = D(-8+7, 6-3),
B(-3, 6) → E(4, 3) = E(-3+7, 6-3)
and
C(-7, 4) → F(0, 1) = F(-7+7, 4-3).
Therefore, the required transformation rule is given by
(x, y) → (x+7, y-3).
Thus, (C) is the correct option.

Answer:
A.
Step-by-step explanation:
We have that C>0, D>o and C > D. Now,
A. [tex](C+D)^2= C^2+2CD+D^2[/tex]
B. 2(C+D) = 2C+2D
C. [tex]C^2+D^2[/tex]

We have that [tex]C^2+2CD+D^2> C^2+D^2[/tex] (beacuse on left we have adding one extra positive term) and also [tex]C^2+D^2> C^2-D^2[/tex] (adding two positive values is greater than subtract two positive values), then
[tex]C^2+2CD+D^2> C^2-D^2[/tex]
also, [tex]C^2+2CD+D^2> 2C+2D[/tex] (also because the middle term). Then, the largest term is [tex](C+D)^2= C^2+2CD+D^2[/tex].

I keep seeing 7√2 and I'm just wondering if the number outside of the radical is being multiplied by the square root, or if there is a deeper meaning. I can't really explain well, but if the square root of 2 is about 1.41 then would I multiply 1.41 by 7 to get 9.87? Or..?
Answers
you are right, when you see a number like 7√2
you would multiply 7 by √2
which = 7 x 1.41 = 9.87
A cookie recipe for three dozen Caramel peanut butter bars uses 14oz of caramel. How much caramel (to the nearest ounce) should be used to make 120 bars for a cookie exchange
Answers
To make 120 caramel peanut butter bars, using a recipe that calls for 14 ounces of caramel for 36 bars, one would need 47 ounces of caramel (rounded to the nearest ounce).
Explanation:Given that a cookie recipe for three dozen caramel peanut butter bars uses 14 ounces of caramel, we need to determine the amount of caramel needed to make 120 bars. Since three dozen bars are equal to 36 bars, we can find how many times the amount of bars in the recipe fits into the desired 120 bars count by dividing 120 by 36.
This gives us 120 / 36 = 3.33. Multiplying this factor by the amount of caramel used for 36 bars gives us the amount needed for 120 bars: 3.33 * 14 ounces = 46.62 ounces. Therefore, 47 ounces of caramel (rounding to the nearest ounce) should be used to make 120 bars for a cookie exchange.

Represent the unknowns: d for Doug, a for Anne.
Then d=34 years.
Doug is twice Anne's age, so d=2a. But d=34 yrs, so 34 yrs = 2a.
Solve this for a: a = 34 yrs / 2 = 17 yrs
Doug is 34, Anne is 17.

Let x be the first factor in an expression in scientific notation. Describe the possible values of x.
Answers
In scientific notation, the coefficient is a number from 1 to 10 multiplied by a power of 10, which represents the number of decimal places moved to convert a number to this format.
Explanation:The first factor in an expression in scientific notation is the coefficient, which must be a number equal to or greater than 1 and less than 10. The coefficient is then multiplied by a power of 10 to represent the original number accurately.
For example, to write the number 79,345 in scientific notation, one would express it as 7.9345 × 104, because we have moved the decimal place to make 79,345 into 7.9345 while recording that we have moved the decimal place four positions to the right, hence the power of 10 being 4.

write an equation and solve
Answers
To solve the equation r + (-6) = -10, since -6 is being added to r, we need to subtract -6 from both sides of the equation.
It's important to understand that minus a negative means the same thing as plus a positive so we're really adding 6.
On the left side of the equation, the -6 and +6 cancel out and we have r. On the right side of the equation, -10 + 6 is -4.
So we have r = -4 which is the solution to our equation.
3 erasers cost $4.41
Witch equation will help determine the cost of 4 erasers
Answers
To determine the cost of 4 erasers, set up a proportion using the given information.
Explanation:To determine the cost of 4 erasers, we can set up a proportion using the given information. We know that 3 erasers cost $4.41, so we can write the equation:
3 erasers / $4.41 = 4 erasers / x
To solve for x, we can cross-multiply:
3 * x = 4 * $4.41
x = (4 * $4.41) / 3
Calculating this, we find that the cost of 4 erasers is $5.88. So, the equation that will help determine the cost of 4 erasers is 3 erasers / $4.41 = 4 erasers / $5.88.
The correct equation that represents this relationship and would help determine the cost of 4 erasers is:[tex]\[ \frac{4}{x} = \frac{3}{4.41} \][/tex]
The correct option is (A).
The image shows multiple choice options for equations that could be used to determine the cost of 4 erasers given that 3 erasers cost $4.41.
To find the cost of 4 erasers, we would want to set up a proportion where the number of erasers is directly proportional to the total cost. Given that 3 erasers cost $4.41, we can write this relationship as:
[tex]\[ \frac{\text{Number of erasers}}{\text{Cost}} = \frac{3}{4.41} \][/tex]
We want to find the cost for 4 erasers, so we can set up an equation with [tex]\( x \)[/tex] representing the unknown cost for 4 erasers:
[tex]\[ \frac{4}{x} = \frac{3}{4.41} \][/tex]
This equation can be solved to find \( x \), the cost for 4 erasers. We can cross multiply to solve for \( x \):
[tex]\[ 3 \times x = 4 \times 4.41 \][/tex]
[tex]\[ x = \frac{4 \times 4.41}{3} \][/tex]
Let's solve for[tex]\( x \)[/tex] to find the cost of 4 erasers.
The cost for 4 erasers, given that 3 erasers cost $4.41, would be $5.88.
The correct equation that represents this relationship and would help determine the cost of 4 erasers is:
[tex]\[ \frac{4}{x} = \frac{3}{4.41} \][/tex].

An aquarium with a square base has no top. There is a metal frame. Glass costs 8 dollars/m^2 and the frame costs 7 dollars/m. The volume is to be 20 m^3. Express the total cost C in terms of the height h in meters. (Hint: work out the cost of the glass and frame separately.)
Answers
Then area of the base = x². So volume of the base = x²h.
That gives us x²h = 20. Solving for x, we get x = √(20/h²).
Glass is needed to cover the sides of the aquarium. There are 4 sides and 1 base. Area of a side = hx = h√(20/h²). Area of the base = x² = 20/h. Total area of glass = h√(20/h²) + 20/h. So the cost for glass = 8 * [h√(20/h²) + 20/h] = 8 h√(20/h²) + 160/h.
Metal frame is needed along the edges of the sides. There are 4 edges on the top, 4 edges in the bottom and 4 vertical edges. So the total length of metal frame = 4x + 4x + 4h = 8 √(20/h²) + 4h. Then the cost for metal frame = 7 * [8 √(20/h²) + 4h] = 56 √(20/h²) + 28h.
So the total cost = 8 h√(20/h²) + 160/h + 56 √(20/h²) + 28h
