Answer:
TU = 29
Step-by-step explanation:
TU + UV = TV , substitute values
9x + 2 + 5 = 14x - 8 , that is
9x + 7 = 14x - 8 ( subtract 14x from both sides )
- 5x + 7 = - 8 ( subtract 7 from both sides )
- 5x = - 15 ( divide both sides by - 5 )
x = 3
Then
TU = 9x + 2 = 9(3) + 2 = 27 + 2 = 29
Solve for (x,y,z)
x + 5y + 5z = -10
x + y +z= 2
x + 2y + 3z = -3
Answer:
(5, -1, -2)Step-by-step explanation:
Given system:
x + 5y + 5z = -10 x + y + z = 2 x + 2y + 3z = -3Eliminate one of the variables.
Subtract the second equation from the first and from the third equation:
x + 5y + 5z - x - y - z = -10 - 2 ⇒ 4y + 4z = -12 ⇒ y + z = -3x + 2y + 3z - x - y - z = -3 - 2 ⇒ y + 2z = -5Now subtract the first equation above from the second to solve for z:
y + 2z - y - z = -5 + 3z = -2Find y:
y + z = -3y - 2 = -3y = 2 - 3y = -1Now find x:
x + y + z = 2x - 1 - 2 = 2x - 3 = 2x = 2 + 3x = 5The solution is:

Step-by-step explanation:
Answer:
2x+2y=2
Step-by-step explanation:
2x+2y=....
So you substitute x for 4 and y for -3.
Which would will give you 2(4)+2(-3). 2·4+2·3 which would give you 8+-6
Then you would add 8 and -6.
8+-6
That should give you 2.

Insert grouping symbols to make each number sentence true 7*8-6+3=17
Answer:
7*(8-6)+3
Step-by-step explanation:
Grouping symbols are parentheses; trial and error can lead you to this answer.
Checking, we must use order of operations (PEMDAS). First, we evaluate what's inside parentheses.
7 * 2 + 3
Then multiply:
14 + 3
Then add

A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 116.4-cm and a standard deviation of 0.8-cm. For shipment, 29 steel rods are bundled together. Find the probability that the average length of a randomly selected bundle of steel rods is less than 116-cm.
Answer:
Calculate lengths from each of the lengths (116.4 & 0.8), using the well known formula z = (x-μ) / σ.
Look up the Probabilities associated with those two lengths
Subtract the lesser probability from greater of these two probabilities, to get probability 0.8 in the associated interval.
Two students created a list of steps for the following construction. Which student has steps in the correct order, and which does not? Explain.
You are given and point C. Construct a line parallel to that passes through point C.
Student A Steps:
Student B Steps:
Draw a line that intersects points B and C.
Draw a line through point C and point G.
Keep the compass at the same width, and place it on point C.
Keeping the compass at the same width, place it on point F.
Mark the intersection of the two arcs as point G.
Open the compass to the width between points D and E.
Place the compass on point B, and swing an arc that crosses line AB and line BC. Label the points D and E.
Swing an arc that crosses line BC, and label the point F.
Swing an arc that intersects the arc created from line BC at point C.
Draw a line that intersects points B and C.
Place the compass on point B, and swing an arc that crosses line AB and line BC. Label the points D and E.
Keep the compass at the same width, and place it on point C.
Swing an arc that crosses line BC, and label the point F.
Open the compass to the width between points D and E.
Keeping the compass at the same width, place it on point F.
Swing an arc that intersects the arc created from line BC at point C.
Mark the intersection of the two arcs as point G.
Draw a line through point C and point G.
Answer:
Step-by-step explanation:
As it is impossible to understand who have done what ,
the correct construction should be :
You are given point A, point B and point C.
Construct a line parallel to that line AB passing through point C.
1) Place the compass on point B, and swing an arc that crosses line AB and line BC.
Label the points D and E.
2) Keep the compass at the same width, and place it on point C.
3) Swing an arc that crosses line BC, and label the point F outside the segment [BC] .
4) Open the compass to the width between points D and E.
Keeping the compass at the same width, place it on point F.
5) Swing an arc that intersects the arc created from line BC at point C.
6) Mark the intersection of the two arcs as point G.
7) Draw a line through point C and point G.
You just have to discover who has done that.

Given the piecewise function shown below, select all of the following statements that are true
Answer:
A and C
Step-by-step explanation:
A
when x = 2 , that is x > 1 then f(x) = x² , that is
f(2) = 2² = 4 ← True
B
when x = 5, that is x > 1 then f(x) = x² , that is
f(5) = 5² = 25 ≠ 1 ← not true
C
when x = 1 then f(x) = 5 , that is
f(1) = 5 ← True
D
when x = - 2 , that is x < 1 , then f(x) = 2x , that is
f(- 2) = 2(- 2) = - 4 ≠ 4 ← not true

3³+11-10÷2×4=w
Answer:
18
Brainliest, please!
Step-by-step explanation:
3^3 + 11 - 10 / 2 x 4 = w
27 + 11 - 10 / 2 x 4 = w
27 + 11 - 5 x 4 = w
27 + 11 - 20 = w
38 - 20 = w
w = 18

Compare negative square root of 7 and -3.12345
Answer: Square root of negative 7 is greater than -3.12345
Step-by-step explanation: Since the square root of -7= 2.64575131 i (A positive number) Then it's greater, since the positive number is always greater than the negative numbers, because the negative numbers are further below zero than the positive number, if there is a number below the zero and a number above the zero, the one above the zero is greater, because it's a positive number, the one below 0 is negative.
