You mean, what is this number?
we can rephrase it like this: the sum of a number x and 8 is 15
which is:
x+8=15
we subtract 8 from both sides and we get
x=7
so the answer is 7.
Answer:
64.0% is the correct answer.
Step-by-step explanation:
As per the given scatter plot of voter turnout every year:
X axis represents the year and
Y axis represents the percentage of people who voted.
The model was predicted as per the equation:

<u>To find:</u> Prediction for the year 1900.
Putting the value of
, the value of y will be the predicted value of the model i.e. the value of percentage of voter turnout.

So, the model predicts
for the year 1900.
Answer:



Step-by-step explanation:
we know that
The sum of interior angles in a triangle must be equal to 180 degrees
so

solve for x





Answer:
C, E, F
Step-by-step explanation:
A is false because dilations can not only increase the length of line segments, but also decrease the length of line segments.
B is a true statement.
C is true because when angles undergo dilations, their "size" does not change.
D is false because dilations do not increase the measures of angles.
E is false because a triangle that underwent a dilation becomes similar, not congruent.
F is true because of E's reasoning.
