Answer:
-4
Step-by-step explanation:
y=3x - 1 x= -1
y = 3(-1) -1
y = -3 -1
y= -4
Answer:
1/10
Step-by-step explanation:
1) find a common factor between the two denominators.
2 and 5 have a <u>common factor of 10</u>. you can find this by multiplying the denominators.
2) now that you have a common denominator of 10, you'll need to change the numerators too. you do this by finding out how many times the denominator goes into your common factor. 5 goes into 10 two times so you would multiply 2 x 2. two goes into 10 five times so multiply 5 x 1.
3) you now have both fractions that share a common factor. now you have to subtract them.
5/10 - 4/10 = 1/10
Answer:
Step-by-step explanation:
Since the figures are similar, the corresponding angles are congruent.
Corresponding angles are the angles with vertices with same order number in the name of the figures.
Angles V and E are corresponding as both are the second vertex:
Same for angles W and F (third vertex)
Write out the prime factorization and take numbers out in pairs example:
540= 2x3x3x3x5x2
Take out pairs so take out a three pair and a two pair and what left stays under the root symbol and get multiplied together
6(insert square root sign here) 15
You move the decimal to the right
