Answer:
-26z - 15
Step-by-step explanation:
tp simplify an expression, you combine all the things with z in them and all the plain numbers. In this case you have a negative 20z and a negative 6 z, which makes negative 26z. The only number is -15 so there's nothing to combine with that. Put the pieces together and you have -26z-15
B) 0.6%
The periodic interest rate is found by dividing the annual interest rate by the number of times per year it is compounded.
7.5/12 = 0.625, rounded to 0.6.
Answer:
R= 2/7 or 8/7
Step-by-step explanation:
make a number line of 1/7 fraction and plot the dots
The coefficient of 2(3)(6)Q is 2(3)(6)
<h3>How to determine the
coefficient?</h3>
The expression is given as:
2(3)(6)Q
For an expression
AQ
Where A is a number or product of numbers and Q is a variable
The number A represents the coefficient
By comparing:
AQ and 2(3)(6)Q
We have
A = 2(3)(6)
Hence, the coefficient of 2(3)(6)Q is 2(3)(6)

Triangle ABC would remain the same because a dilation generally preserves the measure of an angle.
<h3>What is scale factor?</h3>
A scale factor simply refers to a ratio of two (2) corresponding side lengths or diameter in two (2) similar geometric figures such as triangles.
In this exercise, you're required to construct a dilation of triangle ABC that is centered at B with a scale factor of 2 by using a compass and straightedge.
In conclusion, triangle ABC would remain the same because a dilation generally preserves the measure of an angle.
