Answer:
the answer is 21
Step-by-step explanation:
4x to the power of 2 + 5x
so: 4*1 the power of 2 +5*1
4to power of 2 +5
and 4 to the power of 2 equals 16 (because 4*4=16) and +5
so 16+5=21
Answer:
ML = 7.5
Step-by-step explanation:
The ratios are the same for both lines.
The one at the top has a 8:10 ratio and the one below has a 6:ML ratio
Convert to fractions and find the value of ML:
8/10 = 6/ML
8*ML= 6*10
ML= 60/8 = 7.5
Answer:
b = -a
Step-by-step explanation:
We know that:
On a number line, the distance between 0 and b is the same distance that between 0 and a (but b and a are in opposite sides of zero).
And we know that, for example, when:
b = 2, a = -2
Remember that the distance between two values is given by:
|n - m|
Then the distance between 0 and b is:
|0 - b|
and the distance between 0 and a is:
|0 - a|
we have:
|-b| = |-a|
|b| = |a|
But the numbers are in opposite sides of the zero, so one must be positive and the other negative, then we can conclude that:
b = -a
or
-b = a
(these are equivalent)
Then the correct option is the first option:
b = -a
1) 12
2) 2y
3) 12+2y
4) 12+2y
