Answer:
z=25
Step-by-step explanation:
(3+5)^2+[8-11]+z=4(z-2)
(8)^2 +3+z=4z-8
square 8
add 8 to both sides
mines z from both sides
64+3+8=3z
75=3z
25=z

Let f(x) = 7x² + 19x + 21 and g(x) = 4x² + 4x + 3 . Identify the solution(s) of f(x) = g(x).
Answer:
-3 and -2
Step-by-step explanation:
7x² + 19x + 21 = 4x² + 4x + 3
combine like terms:
3x² + 15x + 18 = 0
3(x² + 5x + 6) = 0
(x + 3)(x + 2) = 0
x = -3
x = -2

Gina is building a rectangular prism out of sugar cubes for her art class project. She started by drawing a diagram of the rectangular prism that is 4 cubes high, 4 cubes long and 2 cubes wide. How many cubes does she use to make the prism?
The rectangular prism is made up of the dimensions
Lenght = 4 cubes
Width = 2 cubes
Height = 4 cubes
The total number of cubes she needs shall be derived as number of cubes along the lenght multiplied by number of cubes along the width, and then multiplied by number of cubes along the height. Therefore, she would have:
[tex]volume = l \times w \times h \\ volume \: = 4 \times 2 \times 4 \\ volume = 32 \: cubes[/tex]
Therefore, She need 32 cubes to make the prism.
What is the value of the fraction below?
14/0
Answer:
It isn't a number so you would call it undefined
You can think of it like 14 divided by 0 and like siri said “Imagine that you have zero cookies, and you split them evenly among zero friends. How many cookies does each person get? See? It doesn’t make sense. And Cookie Monster is sad that there are no cookies, and you are sad that you have no friends.” In this case, “Imagine that you have 14 cookies, and you split them evenly among zero friends.

f(3) = 12 for a geometric sequence that is defined
recursively by the formula f(n) = 0.5 ∙ f(n – 1), where
n is an integer and n > 0.
Write the equation in explicit form.
Answer:
[tex]f(n) = 96 * 0.5^n[/tex]
Step-by-step explanation:
Given
[tex]f(3) = 12[/tex]
[tex]f(n) = 0.5 * f(n-1)[/tex]
Required
Write as an explicit function
When n = 3, we have:
[tex]f(3) = 12[/tex]
[tex]f(3) = 0.5 * f(3-1)[/tex]
[tex]f(3) = 0.5 * f(2)[/tex]
Substitute: [tex]f(3) = 12[/tex]
[tex]12 = 0.5 * f(2)[/tex]
Solve for f(2)
[tex]f(2) = 12/0.5[/tex]
[tex]f(2) = 24[/tex]
So, we have;
[tex]f(3) = 12[/tex]
[tex]f(2) = 24[/tex]
Since it is a geometric sequence, calculate the common ratio (r)
[tex]r = \frac{f(3)}{f(2)}[/tex]
[tex]r = \frac{12}{24}[/tex]
[tex]r = 0.5[/tex]
Calculate the first term using:
[tex]r = \frac{f(2)}{f(1)}[/tex]
Solve for f(1)
[tex]f(1) = \frac{f(2)}{r}[/tex]
[tex]f(1) = \frac{24}{0.5}[/tex]
[tex]f(1) = 48[/tex]
The explicit function is then calculated as:
[tex]f(n) = f(1) * r^{n-1[/tex] ----nth term of a gp
[tex]f(n) = 48 * 0.5^{n-1[/tex]
Split the exponent
[tex]f(n) = 48 * \frac{0.5^n}{0.5^1}[/tex]
[tex]f(n) = 48 * \frac{0.5^n}{0.5}[/tex]
[tex]f(n) = 96 * 0.5^n[/tex]

Answer:
<ABT = 43°<TBC = 43°Step-by-step explanation:
Given,
Line BT is the bisector of <ABC
So,
3x + 13 = 5x - 7
=> 13 + 7 = 5x - 3x
=> 20 = 2x
[tex] = > x = \frac{20}{2} [/tex]
=> x = 10
As,
We got the value of x = 10
Therefore,
<ABT = 3x + 13 °
= 3×10 + 13 °
= 30 + 13°
= 43°
<TBC = 5x - 7°
= 5 × 10 - 7°
= 50 - 7°
= 43°
Hence,
Value of <ABT = 43° and value of <TBC = 43° (Ans)
What are the missing coordinates of the vertices of this rectangle?
Answer:
A ( -d , e )
B ( - d , -e )
C ( d , - e )
Step-by-step explanation:
The centroid of the circle is on the origin.
This means that coordinates are an equal distance away from each other
Ex. Coordinate A and coordinate B are an equal distance away.
The only difference between the coordinates is the signs of the x and y values
This is determined by what quadrant the specific coordinate is in
Ex. Coordinate A is in Quadrant 2.
Coordinates in Quadrant 2 have a negative x value and a positive x value
Because Coordinate A and the given coordinates ( d , e ) have an equal distance between them all we have to do to find the missing coordinate is add a negative sign in front of the x value (d)
That being said, the coordinate of A is (-d,e).
This process is used to find the rest of the missing coordinates
for B
B lies in Quadrant 3
Quadrant 3 = ( -x , -y )
* add negative signs to the x and y value of the given coordinate *
B = ( -d , - e)
For C
C lies in Quadrant 4
Quadrant 4 = ( x , - y )
* add a negative sign to the y value of the given coordinate *
C = ( d, -e)
The table shows the relationship y = kx.
what is the constant of proportionality, k?
A. 1/5
B. 3/5
C. 5/3
D. 1/3

What does 1,000 pennies + 100 nickels + 10 dimes + 10 quartes equal what?
need it fast plz
Answer:
1850 cents
Step-by-step explanation:
1000 pennies = 1000 cents (Multiply by 1)
100 nickels = 500 cents (Multiply by 5)
10 dimes = 100 cents (Multiply by 10)
10 quarters = 250 cents (Multiply by 25)
Total:
1000 + 500 + 100 + 250 = 1850 cents
find the area of the composite shape
Answer:
96 m²
Step-by-step explanation:
To calculate the area of a composite shape, you must divide the shape into rectangles, triangles, or other shapes.
A = l × w
L = length
W = width
Find the area and then add the areas back together.
12m × 8m
= 96 m²
The area of the composite shape is 96 m²
A circle is centered at the point (-7,-1) and passes through the point (8, 7). The radius of the circle is ___ units. The point (-15, __ ) lies on this circle
Answer:
(x + 7)2 + (y + 1)2 = r2.
To get we use point (8, 7): (8 + 7)2 + (7 + 1)2 = r2, r2 = 225 + 64 = 289 = 172.
So, equation of circle: (x + 7)2 + (y + 1)2 = 289

What is the measure of ∠A, the exterior angle of the triangle shown below?
F. m∠A = 92°, because 180 – (50 + 38) = 92.
G. m∠A = 272°, because 180 – (50 + 38) = 92 and 92 + 180 = 272. H.m∠A=78°,because 50–38=12and90–12=78.
J. m∠A = 88°, because 50 + 38 = 88.
Answer: A is 88
Step-by-step explanation: Sum of all angles is 180 degree.
Let the third interior angle be x.
38+50+x=180
88+x=180
x= 92
A and X are in linear pair.
A+X=180
A+92=180
A=88
