Answer:
Its 69 just use your fingers
Step-by-step explanation:
I do believe that the answer is 900.
Steps:
I first set up a proportion, with 8/100 and 72/x (x being the number we are trying to find)
As I was taught, you multiply 100 by 72, which equals 7,200.
Then, I divided 7,200 by 8, which gave me 900.
This is what the proportion process should have looked like:
8/100 72/x
7,200/8
x=900
I hope this helps!
Answer:
a) On Desmos.
b)The solution set {-2,-2}
Step-by-step explanation:
For drawing a line on graph we require minimum two points.
we have,
Put x = 0,we get
y = 2
∴ Let A (0,2)
Similarly
Put y = 0 we get
x = -1
∴ Let B (-1,0)
Now Draw line AB
For y = -2
It is the line parallel to X axis where Y value is always -2
Now , by drawing these two lines we will get the intersecting point, and this intersecting point is the solution to the system. Let the point be C (-2,-2)
Here we substitute y= -2 in y = 2x + 2 we get
The solution is {-2,-2}
Answer:
C. m∠1 = m∠4
Step-by-step explanation:
A. m∠2 + m∠4 = 180°
∠2 and ∠4 are vertically opp. angles which means m∠2 = m∠4.
Hence, it's a <u>false</u> statement.
B. m∠2 + m∠3 = 180°
∠2 and ∠3 are corresponding angles which means m∠2 = m∠3.
It's a <u>false</u> statement.
C. m∠1 = m∠4
∠1 and ∠4 are another pair of corresponding angles which clearly states that m∠1 = m∠4.
Therefore, it's a <u>true</u> statement.
D. m∠1 = 90°
As clearly visible in the diagram;
It's a <u>false</u> statement.
Answer:
∠ABD =∠DBC (CPCTC)
∠ABC is composed of ∠ ABD and ∠DBC . Since they are equal, BD bisects the ∠ABC
