In the figure, angle DEF is 34x + 11, angle DEG is 2x + 24, and angle GEF is 3x + 12. The value of x is ___.
Answer:
25/29
Step-by-step explanation:
34x+11=2x+24+3x+12
34x+11=5x+36
34x-5x=36-11
29x=25
x=25/29

Write an absolute value equation with the solution -1 and 5
Write an absolute value equation with no solution
the absolute value of -1 is 1 and the absolute value of 5 is 5 since its still positive. I could be wrong so double check with someone else
the absolute value of -1 is 1 and the absolute value of 5 is 5 since its still positive.
find the midpoint of the segment with the given endpoints. (2,9) and (-8,-8)
Answer:
The midpoint is (-3, 1/2)
Step-by-step explanation:
To find the x coordinate of the midpoint, add the x coordinates of the endpoint and divide by 2
(2+-8)/2 = -6/2 = -3
To find the y coordinate of the midpoint, add the y coordinates of the endpoint and divide by 2
(9+-8)/2 = 1/2
The midpoint is (-3, 1/2)

Stella and brain each heat up a small pizza.stella cuts her pizza into 4 equal slices. Brain cuts his pizza into 8 equal parts,Stella eats two pieces of her pizza Brian eats four pieces of his pizza do they eat the same amount of pizza? PLEASE ANSWER!!!!
Answer:
They are the same amount of pizza.
Step-by-step explanation:
Stella cut her pizza into 4 pieces. If she eats 2 pieces, then she has eaten half of her pizza. Likewise, Brian cut his pizza into 8 pieces. If he eats 4 pieces, then he has eaten half of his pizza. Therefore, they have both eaten the same amount of pizza.

A polynomial function h(x) has a zero of x = 2 – 5i with a multiplicity of one. Certain values of h(x) are given in the following table.
x h(x)
–5 0
–2 3
–1 –1
1 2
4 0
7 6
10 5
If every real x-intercept of h(x) is shown in the table and each has a multiplicity of one, what is the degree of h(x)?
A. 2
B. 3
C. 4
D. 5
Using function concepts, it is found that the degree of the function is: 4, option C.
----------------------------------------
The x-intercepts of a function are the values of the function for which the output is zero.The degree of a function is the sum of the multiplicities of the x-intercepts of the function.If a function has a complex root, it means that the conjugate is also a root.----------------------------------------
When [tex]x = -5, h(x) = 0[/tex], thus, x = -5 is one x-intercept.When [tex]x = 4, h(x) = 0[/tex], thus, x = 4 is one x-intercept.There is also a x-intercept(zero) at [tex]x = 2 - 5i[/tex]. There will also be a x-intercept at the conjugate, which is [tex]x = 2 + 5i[/tex].Thus, there are 4 x-intercepts, all with multiplicity 1, which means that the degree of h(x) is 4, option C.A similar problem is given at https://brainly.com/question/10539060

Answer:

Step-by-step explanation:
Triangles: RST and RPQ are similar so
Triangle RST has 12.5 and x
Triangle RPQ has 20 (comes from 12.5+7.5) and x+4.5
Therefore you divide
x/x+4.5 = 12.5/20
20x= 12.5x+56.25
7.5x=56.25
x=7.5
If f(x)=3x^2-2x+4 and g(x)=5x^2+6x-8,find (f-g) (x)
Answer:
-2x^2-8x+12
Step-by-step explanation:
f(x)=3x^2-2x+4
g(x)=5x^2+6x-8
(f-g) (x)= 3x^2-2x+4 - (5x^2+6x-8)
Distribute the minus sign
(f-g) (x)= 3x^2-2x+4 - 5x^2-6x+8
Combine like terms
=-2x^2-8x+12
Answer:
[tex] - 2( {x}^{2} - 4x + 6)[/tex]
Step-by-step explanation:
[tex] f(x)=3x^2-2x+4 \\ g(x)=5x^2+6x-8 \\ (f-g) (x) = 3 {x}^{2} - 2x + 4 - (5 {x}^{2} + 6x - 8) \\ = 3 {x}^{2} - 2x + 4 - 5 {x}^{2} - 6x + 8 \\ = - 2 {x}^{2} - 8x + 12 \\ = - 2( {x}^{2} - 4x + 6)[/tex]

When commercial aircraft are inspected, wing cracks are reported as nonexistent, detectable, or critical. The history of a particular fleet indicates that 70% of the planes inspected have no wing cracks, 25% have detectable wing cracks, and 5% have critical wing cracks. Five planes are randomly selected. Find the probability that
a. one has a critical crack, two have detectable cracks, and two have no cracks.
b. at least one plane has critical cracks.

6 pounds of apples cost $12 how much do 8 pounds cost?
Answer:
8=$16
Step-by-step explanation:
6=$12
divide both sides by 6
1=$2
so one pound equals $2 so if 6 pounds equals $12 just add 2 pounds to 6 to make it 8 pounds. you added two pounds so that means you have to add $4 to the total witch will give you
8=$16

Answer:
7k + 4
Step-by-step explanation:
I don't know what ON SA means, but here's how I solved it:
(k - 4k + 7) + (k + 9k – 3)
(-3k + 7) + (10k - 3)
(-3k + 10k) + (7 - 3)
7k + 4

what’s the solution for
-108pi=6pij
Answer:
j is -18
Step-by-step explanation:
[tex] - 108pi = 6pij \\ - 108 = 6j \\ j = - 18[/tex]
The solution is j = -18 for the expression -108π = 6πj
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
The operator that performs the arithmetic operations is called the arithmetic operator.
Operators who let do basic mathematical calculations.
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
Given that the expression
⇒ -108π = 6πj
Divided by 6π both sides
⇒ -108π/6π = 6πj/6π
⇒ -18 = j
⇒ j = -18
Thus, the solution is j = -18 for the expression -108π = 6πj

For plotting the first one we first need to see the integer as here is 1 we will move to 1. Now, here it is given 0.25. Each line between 1 and 2 has 10 numbers gap so, as it 25 > 20 and 25 < 30. So, we should plot it between the 2nd and the 3rd line. As it is 5 it should be in between the line.
Refer the plotting for better identification
Add :
4.2 + (-0.4)
4.2 - 0.4

For plotting this one we will move to 3 than it has 8 < 10 so it should be plotted within the first dot.
