how do i evaluate exponantial numbers
Answer:
Evaluating Exponents. An exponent is a number that tells how many times the base number is used as a factor. For example, 34 indicates that the base number 3 is used as a factor 4 times. To determine the value of 34, multiply 3*3*3*3 which would give the result 81

I’m a bit confused on how to solve this problem, and could use some help!
Answer:
Okay to start with we know this side isn't congruent to our side with 55 degrees looking at this side we can see that x is not 95 degrees because it is an acute angle so A is crossed out. Next this side isn't congruent like I said so B is crossed out. C is possible but the angle wouldn't be as wide as it is if we had 59 degrees so C is incorrect. Leaving us with D 70 degrees hope this helps and sorry if I got it wrong!
Step-by-step explanation:
x + 3 = −x − 3
Solve for x
[tex]x = - 3[/tex]
Explanation :[tex]x + 3 = - x - 3[/tex]
[tex]x + 3 + x = - x - 3 + x[/tex]
[tex]2x + 3 = - 3[/tex]
[tex]2x = - 3 - 3[/tex]

i need help please, ill give a brainlist to the best answer.
Step-by-step explanation:
y = 6x - 24
y = -2x
=> 6x - 24 = -2x [We change the two sides of y = two equations x above]
=> 6x - 24 + 2x = 0
=> 8x = 24
=> x = 3
=> y = -2 x 3 = -6
=> The correct ans will be (3 , -6) [x is always placed before y]

Step-by-step explanation:
have a good day
Answer:
The Answer is 8
Step-by-step explanation:
Hello,
The answer to the question is 8, let me explain why.
1. we know how many balloons Fred can blow up in 15 minutes
Fred can blow up 20 balloons in 15 minutes.
2. we need to find out how many balloons Fred can blow up in 1 minute.
To solve this we just divide 20 by 15
20 ÷ 15 = 1.3 (repeated)
3. Finally we multiply the answer by 6
This will give us the answer of 8
because 1.3 × 6 = 8
Hope I could help, Hope it was easy to understand as well.

Write a quadratic equation could some please help asap
Answer:
f(x) = x^2 + 3x + 2.
Step-by-step explanation:
The zeroes of the quadratic function are -1 and -2 so we can write it as:
f(x) = a(x + 1)(x + 2) where a is some constant.
Now, when x = 1, f(x) = 6 so
6 = a(1+1)(1+2)
6 = a*2*3 = 6a
a = 1.
So the function is f(x) = (x + 1)(x + 2) = x^2 + 3x + 2.

Sandra bought 4 pounds of sweet potatoes for $6.28. What is the cost per pound of the sweet potatoes?
Answer:
Cost of 1 sweet potato is $6.28 divided by 4 which will give $1.75
Answer:
$1.57
Step-by-step explanation:
What we know:
- There are 4 pounds of sweet potatoes
- 4 pounds of sweet potatoes cost $6.28
To find the cost per pound of sweet potatoes, divide $6.28 by 4.
6.28 ÷ 4
= $1.57
Therefore, the cost per pound of sweet potatoes is $1.57.

The variables a and b vary directly, and b=8 when a=2.
What is the direct variation equation that relates a and b?
A.
b=2a.
B.
b-4a
C
b=8a
D
b=16a
Answer: b= 4a
( This is the correct answer, which is supposed to be option b, but a negative sign was put instead of an equal sign, so you can change appropriately)
Step-by-step explanation:
Given that a and b vary directly, can be expressed as
a ∝ b
Introducing the constant of proportionality, k, we have that
a = kb
so when a= 2, b= 8 and the constant becomes
2 = k8
k = 2/8=1/ 4
a= 1/4b
Such that
b=4a
