Answer:
DE=25
Angles CDE & CAB are equal since they are alternate angles.
Step-by-step explanation:
Triangle CDE is an reduction of triangle CAB.
Reduction Ratio=
Angles CDE,CAB relationship- the two angles fall on opposite relative sides of two parallel lines are therefore equal.
The angle supplementary to the angle 39° Mabel measured is C. 129°.
When the sum of the two angles is 180° they are said to be supplementary.
When the sum of the two angles is 90° they are said to be complementary.
Given, Mabel measured an angle on her math worksheet with her protractor. The angle measured 39°.
Therefore, The angle supplementary to the angle she measured is,
= (180 - 39)°.
= 129°, As the sum if the sum of two angles are supplementary their sum is
180°.

B. Three divided by a number minus fifteen.
C. Three divided by a number less than fifteen.
D. A number divided by three less than fifteen.
Answer:
A
Step-by-step explanation:
X can be referred to as a number here because it can be anything.
and X is being divided by three there.
also according to the
B brackets
O order or power
D division
M multiplication
A addition
S subtraction
BODMAS rule division would be done before you subtract the 15
I hope you do well in the future!!! Believe in yourself!
The best description for the algebraic expression x/3 - 15 is 'A number divided by three minus fifteen'. This description accurately represents the mathematical operations indicated in the expression.
The algebraic expression x/3 - 15 best described by: 'A number divided by three minus fifteen.' This is a result of the mathematical symbols represented in the expression. The expression x/3 is read as 'a numberdivided by three,' and the '- 15' translates to 'minus fifteen.' Therefore, the entire expression, x/3 - 15, describes a scenario where a number is divided by three, and then fifteen is subtracted from the result.

a. Let f(x) = 9x − 1.
Answer:
Range of f=R
Step-by-step explanation:
We are given that a function
We have to find the range of given function.
The given function is linear function because the degree of function is 1.
When the degree of function is 1 then the function is called the linear function.
The domain of linear function is a set of real numbers because it can be defined for all real values of x.
Domain of given function =R
When we substitute the real value of x in given function then we get a real number also.
Therefore, the range of f=R
