Answer:
362
Step-by-step explanation:
Let the ones digit equal x. If the ones digit is one, then the hundreds digit is one more than it or x + 1. And, since the tens digit is twice the hundreds digit, you can say it is 2(x + 1) or as simplified: 2x + 2. Now, we are given the sum of the digits is 11, so if we add all of them, they should be equal to 11:
x + x + 1 + 2x + 2 = 11
We can combine like terms:
4x + 3 = 11
4x = 8
x = 2
So, the ones digit is 2. Since the hundreds digit is one more, it's 3. And because the tens is twice the hundreds, it's 6. The number is 362.
Answer: The slope should be the first one. 1/4
Hope this helps <3.
Answer:
Because if you were to distribute it back into the original equation you were given it would distribute back into 9x^2-12x+4. Your signs are wrong. So change it to (3x+2) (3x+2)
Step-by-step explanation: change your signs in your answer you gave to positive. :)
Answer:
Option B) ∠DCE is congruent to ∠BCA by the Vertical Angles Theorem and 15 over 5 equals 12 over 4 shows the corresponding sides are proportional; therefore, ΔABC ~ ΔEDC by the SAS Similarity Postulate
Step-by-step explanation:
we know that
The SAS Similarity Theorem states that if two sides in one triangle are proportional to two sides in another triangle and the included angle in both are congruent, then the two triangles are similar
we have that
m∠DCE≅m∠BCA -----> by vertical angles
substitute the values
----> is true
so
Two sides in triangle ABC are are proportional to two sides in triangle EDC and the included angle in both triangles are congruent
therefore
ΔABC and ΔEDC are similar by SAS Similarity Postulate
Start at 4 on the y azures and go down 1 and over 3
