Answer:
6z-7>8z+2? = z < -9/2
Step-by-step explanation:
6*z-7-(8*z+2)>0
-2z - 9 = -1 • (2z + 9
Multiply both sides by (-1)
Flip the inequality sign since you are multiplying by a negative number
2z+9 < 0
Divide both sides by 2
z+(9/2) < 0
Subtract 9/2 from both sides
z < -9/2
Answer: z < -9/2
Answer:
z is (less than) -9/2 is the correct answer use the symbol for less than.

Write the equation of a line going through the points (4,2) and (7,-3).
Answers
Answer:
Equation of the straight line passing through the point ( 4,2) and (7,-3) is
5 x + 4y - 28=0
Step-by-step explanation:
Step(i):-
Given points are ( 4,2 0 and ( 7,-3)
Slope of the line
[tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} } = \frac{-3-2}{7-4} = \frac{-5}{4}[/tex]
Step(ii):-
Equation of the straight line passing through the point ( 4,2) and
having slope m = [tex]\frac{-5}{4}[/tex]
y - y₁ = m( x- x₁ )
[tex]y - 2 = \frac{-5}{4} ( x-4)[/tex]
4( y -2) = -5( x-4)
4 y - 8 = - 5x +20
5x +4y -8 -20=0
5 x + 4y - 28=0
Final answer:-
Equation of the straight line passing through the point ( 4,2) and (7,-3) is
5 x + 4y - 28=0

2. If you buy a new mint-condition action figure, worth $106 and
your baby brother bent the packaging which reduced the value
by 22%, what is the new value of your figure?
Answers
Answer:
$82.68
Step-by-step explanation:
Original price of mint - $106
Percent discount = 22%
Discount price = 22/100 * 106
Discount price = 0.22 * 106
Discount price = $23.32
New value = Original price - discount price
New value = 106 - 23.32
New value = 82.68
Hence the new value of the figure will be $82.68

A hobby store marks up remote-controlled cars 20%. The original price was $35. What is the retail price to purchase a remote-controlled car at the hobby store?
Answers
Answer:
The retail price to purchase a remote-controlled car at the hobby store is $42
Step-by-step explanation:
Original Price of remote controlled car = $35
Mark up = 20%
We need to find retail price.
First we will find mark up value i.e. 20% of 35 and then add it to the original price to find retail price.
Finding 20% of 35
[tex]20\% \:of\: 35\\=\frac{20}{100}\times 35\\=7[/tex]
So, mark up price is $7
Now, the retail price will be:
Retail price = Original Price + Mark up
Retail price = 35 + 7
Retail price = 42
So, the retail price to purchase a remote-controlled car at the hobby store is $42

Is 3 a factor of 245 - 16?
yes
no
HELPPP
Answers
Answer:
No
Step-by-step explanation:
For 3 to be factor your finale number has to be divisible by 3, so with that information all you have to do is subtract 245-16 which is 229, and if you divide 229 by 3 it does not equal a whole number so 3 cannot be a factor.
