Answer: -2
Step-by-step explanation: When your adding and subtracting positives and negatives, it helps to use a number line to visualise what's going on in the problem.
On a number line zero is in the middle. All numbers to the right of zero are positive and all numbers to the left of zero are negative.
So when your simplifying a problem like 3 + (-5), we start at zero and positive 3 takes us to the right. From there, -5 moves us 5 units back to the left and we end up -2. So 3 + (-5) simplifies to -2.
I have attached a number line along with my work
for this problem below.
Answer:
y = 3x/2 +14
Step-by-step explanation:
gradient = -2/3
so if perpendicular,
-2/3 * m2 = -1
m2 = 3/2
if crosses throguh ( -4, 8 )
y - 8 = 3/2 ( x - - 4)
y = 3x/2 + 14
QR. because if BCDE is congruent to OPQR then the sides and angles will be the same also by either sss, sas, asa, or aas depending on how the shape is.
Answer:
its c
Step-by-step explanation:
Our denominators are 40 and 4. What we need to do is find the lowest common denominator of the two numbers. This is the smallest number that can be divided by both 40 and 4. In this case, the lowest common denominator is 40.
If we multiply the first denominator (40) by 1 we will get 40. If we multiply the second denominator (4) by 10 we will also get 40. We also need to multiply the numerators above the line by the same amounts so that the fraction values are correct:
<u>33 x 1
</u>
40 x 1
<u>3 x 10
</u>
4 x 10
This is what 33/40 and 3/4 looks like with the same denominator:
<u>33
</u>
40
&
<u>30
</u>
40
Now that these fractions have been converted to have the same denominator, we can clearly see by looking at the numerators that 33 is greater than 30 which also means that 33/40 is greater than 3/4.
2x-11
if you take the cube root of the entire answer
it would be 2x-11
