Answer: 60º
Step-by-step explanation:
With respect to the line ZB, it makes an angle of 180º if measured using DZ. If the angle outside the triangle measures 140º, subtract from 180º to find the angle inside the triangle.
180º-140º=40º
So, now we have angle c=80º and angle b=40º, we can make an equation to find angles D which we'll call x.
The sum of the angles of a triangle must be equal to 180º.
80+40+x=180
120+x=180
x=180-120
x=60
Answer:
y= -0.2x+14
Step-by-step explanation:
you have to do y2-y1/x2-x1 of any two coordinates or points so you could do 9.8-10.2/21-19 then you get -0.4/2 and that equals -0.2 so -0.2 is now ur slope or M. Next you pick any coordinate like (19,10.2) and you plug that into ur y=mx+b to find the b since you have found the m already from y2-y1/x2-x1. You could do 10.2= 19(-0.2)+b once you do the algebra to solve this you get 14 as your b or y intercept
Answer:
A <u>bi-conditional statement</u> represents the idea of "if and only if." Its symbol is a .
Step-by-step explanation:
We have been given an incomplete sentence. We are supposed to fill in the given blank.
A _______ represents the idea of "if and only if." Its symbol is a .
We know that "if and only if" stands for bi-conditional statement, which represents either both statements are true or both are false.
The symbol represent a bi-conditional statement.
Therefore, our complete statement would be: A <u>bi-conditional statement</u> represents the idea of "if and only if." Its symbol is a .
Answer:
30% of 200 is 60
Step-by-step explanation:
Option B: is the new equation
Explanation:
The given equation is
We need to find the new graph which is shifted 7 units up and 4 units right.
First, we shall shift the graph 7 units up.
The general formula to shift the graph b units up is given by
Thus, to shift the graph 7 units up, let us substitute and in the general formula, we have,
Now, we shall shift the graph 4 units right.
The general formula to shift the graph b units right is given by
Thus, to shift the graph 4 units right, let us substitute and in the above equation, we have,
Therefore, the new equation is
Therefore, Option B is the correct answer.
