Answer: 8.8 (-8.8'F)
Step-by-step explanation:
What we know:
Temperature started as 7.2Temperature ended as -1.6We need to find the differenceHow to solve:
By doing simple subtraction, we can solve this.
Process:
Write equation 7.2 - (-1.6) = ?Simplify 7.2 + 1.6 = ?Solve = 8.8Solution: 8.8 (-8.8'F)
*Note: The temperature decreased by 8.8'F, but it increased/changed by -8.8'F. Be careful of wording.

Triangle BCD With Vertices B(4,4), C(8, 14), And P(12, 0); K = 1/4
Answer:
Hello, I am not sure if you mean a dilation by 1/4. If it is, this will be the answer:
B (1, 1)
C (2, 3.5)
D (3, 0)
Step-by-step explanation:
Just divide each number by 4. B (4, 4) = B (4/4, 4/4) = B (1, 1)
Continue to do this for each coordinate set given.
Hope this helps!
The vertices of triangle B'C'D' are:
B'(-1, -1/2)
C'(0, 2)
D'(1, -3/2)
What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
To find the vertices of triangle B'C'D', which is a dilation of triangle BCD with center at the origin and a scale factor of 1/4,
We can follow these steps:
Find the coordinates of the centroid of triangle BCD.
The coordinates of the centroid G are:
[tex]x_G = (x_B + x_C + x_D) / 3 = (4 + 8 + 12) / 3 = 8[/tex]
[tex]y_G = (y_B + y_C + y_D) / 3 = (4 + 14 + 0) / 3 = 6[/tex]
Translate triangle BCD so that its centroid is at the origin.
We can do this by subtracting the coordinates of the centroid from the coordinates of each vertex:
B(4, 4) → [tex]B_1(4 - 8, 4 - 6) = B_1(-4, -2)[/tex]
C(8, 14) → [tex]C_1(8 - 8, 14 - 6) = C_1(0, 8)[/tex]
D(12, 0) → [tex]D_1(12 - 8, 0 - 6) = D_1(4, -6)[/tex]
Dilate the translated triangle [tex]B_1C_1D_1[/tex] by a scale factor of 1/4.
To do this, we can multiply the coordinates of each vertex by 1/4:
[tex]B_1[/tex](-4, -2) → B'(-4 x 1/4, -2 x 1/4) = B'(-1, -1/2)
[tex]C_1[/tex](0, 8) → C'(0 x 1/4, 8 x 1/4) = C'(0, 2)
[tex]D_1[/tex](4, -6) → D'(4 x 1/4, -6 x 1/4) = D'(1, -3/2)
Therefore,
The vertices of triangle B'C'D' are:
B'(-1, -1/2)
C'(0, 2)
D'(1, -3/2)

A plant is 5cm tall and growing at a rate of 3cm a month. What equation is right?
1. y=5x+3
2. y=5-3x
3. y=3x+5
Answer:
y=3x+5
Step-by-step explanation:
The plant starts at 5cm so +5 is the starting height, It grows at 3cm a month making 3x the growth rate. so 3x+5 is the height of the plant every month.

Graph the solution to this inequality on the number line. −1/3x + 1/2 ≥ −3/4
Answer:
4.5 (4.5 units to the left of 0) Make sure to draw a solid dot over 4.5 and an arrow pointing in the right direction.
>= is the greater than or equal to symbol
Step-by-step explanation
1. Combine like terms- In this problem, the like terms are 1/2 and -3/4, so to move 1/2 over to the other side of the equation, we have to divide each side by 2/1, which is the same as multiplying each side by 2: -1/3x + 1/2 * 2 >= -3/4 * 2.
2. Separate the fraction from x- Now, we simply divide each side by -3/1, which is the same as multiplying each side as -3: -1/3x * -3 >= -3/2 * -3
3. Graph on the number line- We've found that x = 4.5. To check, substitute in 4.5 for the value of x: -1/3(4.5) + 1/2 >= -3/4. -1 >= -3/4 is a true inequality. To graph it on the number line, draw a solid dot over 4.5 and an arrow in the direction of the righthand side.

12. Multiply the following binomials:

b. (s - 2)(2s - 12)
c. (4s - 12)(2s + 4)
d. (2x - 4)(2x - 4)
Answer:
a) x^2 - x -12
b) 2s^2 - 16s + 24
c) 8s^2 - 8s -48
d) 4x^2 - 16x + 16
Answer:
a. x^2 - x - 12
b. 2s^2 - 16s + 24
c. 8s^2 - 8 - 48
d. 4x^2 - 16 + 16
Step-by-step explanation:
You need to use distributive property find the answer.
(x + 3)(x - 4)
>> (x)(x) = x^2
>>(x)(-4) = -4x
(3)(x) = 3x
(3)(-4) = -12
The result will be x^2 -4x + 3x -12
You can simplify this by adding the like terms:
x^2 -4x + 3x -12
>> x^2 - x - 12
Just do the same for the rest of them by using distributive property.

Answer:
[tex]a_n=-8+(n-1)-7[/tex]
Step-by-step explanation:
General arithmetic sequence formula: [tex]a_n=a_1+(n-1)d[/tex]
where [tex]a_1[/tex] = first term, and d = common difference.
The first term is -8
And the common difference appears to be - 7 as 7 is subtracted to get to the next term. Ex. -8 - 7 = -15, -15 - 7 = - 22 and so on.
To get the explicit formula of the sequence we simply plug in the values of a1 and d the general arithmetic sequence formula
General formula: [tex]a_n=a_1+(n-1)d[/tex]
We have [tex]a_1=-8[/tex] and d = -7
So the formula to find the nth term would be
[tex]a_n=-8+(n-1)-7[/tex]
