Answer:
Step-by-step explanation:
No the following number is not a scientific notation because The proper format for scientific notation is a x 10^b where a is a number or decimal number such that the absolute value of a is greater than or equal to one and less than ten or, 1 ≤ |a| < 10. b is the power of 10 required so that the scientific notation is mathematically equivalent to the original number.
need help with this 3 = x+3 - 5x
Answer:
x=0 (No solution)
Hope this helps!
Answer:
x=0
Step-by-step explanation:
3=x+3−5x
3=x+3+−5x
3=(x+−5x)+(3)(Combine Like Terms)
3=−4x+3
3=−4x+3
Step 2: Flip the equation.
−4x+3=3
Step 3: Subtract 3 from both sides.
−4x+3−3=3−3
−4x=0
Step 4: Divide both sides by -4.
−4x
−4
=
0

What are the slope and the y-intercept of the line shown in the graph?
A. y-intercept = 2 and slope = -3
B. y-intercept = 2 and slope = 3
C. y-intercept = 3 and slope = 2
D. y-intercept = -3 and slope = 2
Answer:
A
Step-by-step explanation:
The y intercept is where the line crosses the Y (vertical) axis. In this case, it happens at y=2
The slope is the rate of change. For every 1 space it moves on the horizontal axis, it moves 3 vertical spaces. It is going down, so it is -3

What is the scale factor (k) of the dilation if C is (-6,9) and C' is (-2,3)?
Answer:
Step-by-step explanation:
Given the original coordinate as C (-6, 9) and new coordinates after dilation as C' (-2, 3), we can see that the value of the new coordinates has reduces by a factor. Let the factor be k
For the x coordinates:
C' = kC
x' = kx
-2 = k(-6)
-2 = -6k
Divide both sides by -6
k = -2/-6
k = 1/3
For the y-coordinates:
y' = ky
3 = 9k
Divide both sides by 9:
3/9 = 9k/9
1/3 = k
k = 1/3
Hence the scale factor of the dilation is 1/3
Answer:
The scale factor from C' to C is
3
But the scale factor from C to C' (the one you may have asked for in the question) is
[tex]\frac{1}{3}[/tex]
Step-by-step explanation:
What we already know is that we have line segments C and C' and we know their lengths.
C = (-6, 9)
C' = (-2, 3)
So the scale factor from C' to C can be easily known if we simply use the rules of division
-6 ÷ -2
and
9 ÷ 3
They both are equal to the outcome, 3.
So we now know that the scale factor from C' to C is 3.
But what about C to C'??
Yes we still have to do division, BUT (you may have guessed it already but), we must switch the positions that the numbers for dividend and divisor were.
-2 ÷ -6 =
0.33333333... or [tex]\frac{1}{3}[/tex]
3 ÷ 9 =
0.33333333... or [tex]\frac{1}{3}[/tex]
So we can decisively conclude that the scale factor of C to C' is [tex]\frac{1}{3}[/tex]

Pls consider marking my answer as Brainliest! It would mean a lot!
The perimeter of the rectangle is 48 feet. The length is 16 ft. What is the
width?
is the length both sides already or just on one side?
because if the 16ft. is only on one side, and the sum of the both sides are 32ft, i think the width of the rectangle must be 16ft, which means 8ft from the first side and 8ft from the second side.
but if the 16ft. is the sum of both sides, which means 8ft from the first length and 8ft from the second length, then the answer for the width is 16ft, for each side of the width. 16 for the first width, and 16 for the second width.
is my explanation too complicated?? sorry hehe.

3xsquared +13x-10
HELPP PLEASE
Answer:
(x + 5)(3x - 2)
Step-by-step explanation:
Assuming you require the expression factorised.
3x² + 13x - 10
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 3 × - 10 = - 30 and sum = + 13
The factors are + 15 and - 2
Use these factors to split the x- term
3x² + 15x - 2x - 10 ( factor the first/second and third/fourth terms )
= 3x(x + 5) - 2(x + 5) ← factor out (x + 5) from each term
= (x + 5)(3x - 2) ← in factored form
Simplify:

15 - 5k ≥ 0
solve the inequality
The solution is, the value of the inequality is, 3 ≥ k.
What is inequality?An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.
here, we have,
given that,
15 - 5k ≥ 0
now, we get,
Start by adding 15 to both sides
15 + 15 will cancel out
15 + 0 = 15
After you are left with just 5k and 15
Divided 5 on both sides of the inequality
5k/5 ( this will cancel out)
15/5 = 3
Bring down the k & inequality sign
3 - k ≥ 0
adding k on both side,
3 ≥ k
Final Answer : 3 ≥ k

7. Francis made 7 withdrawals of
$75 each from his bank account.
What was the overall change in
his account?
Answer: -$525
Step-by-step explanation:
7x = how many times he withdrew money * how much money he withdrew.
7 * 75 = $525
Francis ended up removing $525 from his bank account, if we assume that he started off with $0- then the change would be -525 dollars.

Answer:
D. Multiply/divide both sides by the same variable expression.NoStep-by-step explanation:
1) Comparing the two equations, we see that the multiplier 'x' is missing from both sides in equation B. That is, it has been divided out:
(5x)/x = (3x)/x ⇒ 5 = 3
Both sides have been divided by x.
__
2) The equations are equivalent if and only if x ≠ 0. Unfortunately, in equation A, the only solution is x = 0. For equations like the one in A, it is better to subtract one side from both:
5x -3x = 3x -3x ⇒ 2x = 0
Now, dividing by 2, it is clear that the solution is x = 0.
Equations A and B are not equivalent, because the condition on the division property of equality was violated (you cannot divide by 0).
