Answer:
if that statement is true, then DE=ST, and ST=4 so your answer should be DE=4
Explanation:
you can tell that they are even from looking at the first statement, it states DEF=STU, emphasizing on the DE=ST part, it gives your the answer right there because ST=4

if x cubed = -8, what does x equal
Let's start the sum as follows:
x³ = 8
X × X × X = 8
This means there are 3 number which after Multiplication gives answer 8.
If 2 is multtiplied 3 times it will give you 8
Thus the answer of x is 2
x = 2.
x^3 = -8
The cube root of 8 is 2 = 2 x 2 x 2 is 8.
But, the answer is negative, which means that the cube root of -8 must be -2.
-2 x -2 x -2 = -8
x = -2

A 12-foot ladder is leaning against a wall. The bottom of the ladder is 5 feet away from the bottom of the wall.
Approximately how high up the wall does the top of the ladder reach?
Answer:
10.9 units
Step-by-step explanation:
Let the hight of the wall be " x ".
( Height = x )
Here,
12 foot ladder is the hypotenuse side.
( Hypotenuse = 12 )
5 feet away is the base side.
( Base = 5 )
Formula : -
Height² + Base² = Hypotenuse²
x² + 5² = 12²
x² + 25 = 144
x² = 144 - 25
x² = 119
x = √119
x = 10.9 approximately
Therefore,
High up the wall does the top of the ladder reach is 10.9 units.

By how much would the mode increase if the number 80 were added to the set?
Answer:
The mode would not increase or decrease.
Step-by-step explanation:
I say this because the mode is the value(s) in the data set that occur most frequently. 30 is the mode before adding 80 because 30 is in the set 3 times, more than the other values. Because 80 would be the only 80 in the set it would not become the mode once added. I hope this explained my reasoning and helped!

C. {x | x=2}
D. {x | x=-2,4}
= is not equal to sign
Answer:
{x | x ≠ -1, 2, 4}
Step-by-step explanation:
Domain: input values (x-values)
Asymptote: a line which the curve gets infinitely close to, but never touches.
Hole: a point on the graph where the function is not defined.
From inspection of the graph:
Vertical asymptotes at x = -1 and x = 4Hole at x = 2As vertical asymptotes and holes restrict the domain of a rational function, the domain is {x | x ≠ -1, 2, 4}

3. Look at the set of ordered pairs below. Determine if the three statements that follow are true or false.
If it is true, explain why you know that it is true.
If it is false, explain why you know that it is false and change the statement to a true statement.
{(3,6), (4,6), (5,7), (6,8), (7,10), (8,10)
Statement 1:
The relation is not a function because every y-value has more than one corresponding X-value
Statement 2:
The domain of this relation is 3=< x =< 8.
Statement 3:
The range of this relation is {6, 7, 8, 10}
Answer:
Statement 1 - false
A function is one-to-one or many-to-one.
One-to-one means each value in the range (y-values) corresponds to exactly one value in the domain (x-values)
Many-to-one means some values in the range (y-values) correspond to more than one (many) value in the domain (x-values).
Therefore, as some y-values correspond to more than one x-value, this is a many-to-one function.
The true statement should be:
The relation is a function because some y-values correspond to more than one x-value.
Statement 2- true
The domain is the set of input values (x-values). Therefore, the domain is 3 ≤ x ≤ 8 as the smallest x-value is 3 and the highest x-value is 8.
Statement 3 - true
The range is the set of output values (y-values). Therefore, the range is {6, 7, 8, 10} as these are the y-values of the ordered pairs.
Mrs. Nigrini picks up some grapefruits that each weigh 1/2 pound. When she checks out she finds her bag of grapefruit weighs exactly 6.5 pounds. Each grapefruit costs $1.29. How much did she spend on grapefruit?
Answer:
$16.77
Step-by-step explanation:
1. Grapefruit cost 1/2 pound = 0.5 pound
2. Since the bag weighs 6.5 pounds, you can do 6.5/0.5 to find the number of grapefruits
3. 6.5/0.5 = 13
4. The total cost of the grapefruits would be $1.29 * 13 = $16.77

if angle 6 is 25 degrees how much is 7
Given:
Angle 6 = 25 degrees
To Find:
The value of Angle 7
Solution:
We know that,
the value of Angle 6 is equal to 25 Degrees
Since Angle 6 and Angle 7 together comprise of a Straight Line, this means that they are Supplementary Angles.
Therefore,
Angle 6 + Angle 7 = 180 degrees
This implies that,
25 degrees + Angle 7 = 180 degrees. (since Angle 6 = 25 Degrees)
Angle 7 = (180-25) degrees
Thus ,
Angle 7 = 155 degrees
Hence, Angle 7 is 155 degrees (Option 1)
