Answer:
[tex]-5*2[/tex] is larger.
Step-by-step explanation:
[tex]-5*2=-10[/tex]
[tex]-14+1=-13[/tex]
[tex]-10>-13[/tex]
-10 is greater because both numbers are negative, so -10 is the higher number.
Answer:
5 x 2 is the larger than -14 + 1.
Step-by-step explanation: -5 x 2 = -10, and -14 + 1 = -13. Plz tell me if you got it right.

because if you put A into a calculator it equals 81.
hope this helps
Answer:
81 is the perfect square of the first option
Step-by-step explanation:
It is asking for the perfect square so the third option will be eliminated because that is cubed.
The fourth option will also be eliminated because it is multiplication.
The second option will be eliminated because it has addition.
81 is the perfect square of the first option

Step-by-step explanation:
Donna receives a $100 gift card to MovieStop. Her Blu-ray player is able to play both Blu-rays and DVDS, so she would like to get a combination of both. Each Blu-ray cost $25.99 and DVDs cost $15.99 each. Write an equation modeling the number of Blu-rays, b, and DVDs, d, that Donna can purchase with her gift card.
Answer:
100=25.99b+15.99dStep-by-step explanation:
step one:
let the number of Blu-rays be b and
DVDS be d,
step two:
given that Blu-rays cost $25.99each and
DVDS cost $15.99 each,
we can model the cost of the Blu-rays and DVDS, as
100=25.99b+15.99d
hence the expression for the number of Blu-rays and DVDS, is given as
100=25.99b+15.99d

Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
d) x = 4/3
Step-by-step explanation:
Given equation,
→ -x + (3/7) = 2x - (25/7)
Now the value of x will be,
→ -x + (3/7) = 2x - (25/7)
→ -x - 2x = -(25/7) - (3/7)
→ -3x = -28/7
→ -3x = -4
→ x = -4/-3
→ [ x = 4/3 ]
Hence, the value of x is 4/3.

Answer:
x= 44
Step-by-step explanation:
Add 82+54.
Subtract 136 from 180. Giving you your answer.
Always subtract from 180 since a triangle is always 180.
Can you mark me brainliest? And 5 star?
Answer:
x= 44
Step-by-step explanation:
180 = 82 + 54 + x
180 = 136 + x
180 - 136 = 136 -136 + x
44 = x

What is the slope of the line that passes through (-3,5) & (4,-1)
Answer:
-6/7, the first one
Answer:
[tex]\boxed {m = -\frac{6}{7}}[/tex]
Step-by-step explanation:
Use the Slope Formula to help determine the slope of the two following points:
[tex]m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]
(where [tex](x_{1}, y_{1})[/tex] represents the first point and [tex](x_{2}, y_{2})[/tex] represents the second point)
-Apply the two following points to the formula:
[tex](x_{1}, y_{1}) = (-3, 5)[/tex]
[tex](x_{2}, y_{2}) = (4, -1)[/tex]
[tex]m = \frac{-1 - 5}{4 + 3}[/tex]
-Solve for the slope:
[tex]m = \frac{-1 - 5}{4 + 3}[/tex]
[tex]m = \frac{-6}{7}[/tex]
[tex]\boxed {m = -\frac{6}{7}}[/tex]
Therefore, the slope is [tex]-\frac{6}{7}[/tex].

12=6-90
asap please xoxo!!!!!!
answer:
72
step-by-step explanation:
your question doesn't make mathematical sense how can 12 = 6 then subract 90?
maybe you meant 12 + 6 - 90
if so
the answer is
72
(my work)
12 + 6 = 18
18 - 90 = 72

Match each complex numbers with its corresponding distance to the origin
Answer:
2. z = 1 - 2·i → √5
3. z = 4 + 3·i → 54
4. z = 6 - 8·i → 10
1. z = √5 - i → √6
Step-by-step explanation:
1. z = √5 - i
The distance from the origin = √((√5)² +1²) = √(5 + (-1)²) = √6
Therefore, z = √5 - i → √6
2) z = 1 - 2·i
The distance from the origin = √(1² + (-2)²) = √5
Therefore, z = 1 - 2·i → √5
3) z = 4 + 3·i
The distance from the origin = √(4²+3²)) = √(16 + 9) = √25 = 5
Therefore, z = 4 + 3·i → 5
4) z = 6 - 8·i
The distance from the origin = √(6²+8²)) = √(36 + 64) = √100= 10
Therefore, z = 6 - 8·i → 10

The square root of 20 = 4.47 so a for sure.
But the root of 20 is also -4.48 so that means that 2 and 3 are added to the list
Now what to do about - 8
(- 8)^2 = 64
The square root of 64 = +/- 8
It's kind of slippery but it depends on how you see the problem. It is a bit ambiguous.
I would eliminate - 8 but your instructor may not. Argue that it should not be included, but don't take the argument on forever. Let it go.
a for sure.
b and c I think so.
-8 is iffy.

please help.... it would mean alot & its worth 100 points!
Answer:
y= [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
change them to improper fractions
2 1/2= 5/2 1 2/3=5/3
divide y from 5/3:
[tex]\frac{5}{2} y=\frac{5}{3}[/tex]
mutiply each side by 2/5
y=10/15=2/3
here is your answer. change them to improper fractions
2 1/2= 5/2 1 2/3=5/3
divide y from 5/3:
mutiply each side by 2/5
y=10/15=2/3
