which number best represents the slope of the graphed line?
Answer:( -10,10), (-,+)
Step-by-step explanation:
Awnser:
-2
Step by Step:
To find a slope, you need to find 2 points. You can't have a line with only 1 point.
The equation for a slope is: y2-y1/x2-x1.
It doesn't matter which order you put them in.
I used (-4,1) and (-6,2).
So: 2-1/-6-(-4)
1/-6+4
1/-2
-2
which expression uses the associative property to make it easier to evaluate 14(3/2 . 1/4)?
Answer:
C
Step-by-step explanation:
The expression uses the associative property to make it easier to evaluate 14(3/2 . 1/4) would be equal to (3/2 . 1/4)14
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
The Numbers constants, variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbol; can be used to indicate the logical syntax's order of operations and other features.
Now we have given an expression as;
14(3/2 . 1/4)
Using associative property to make it easier to evaluate;
14(3/2 . 1/4)
= (3/2 . 1/4)14
The correct answer is D.

What is the solution to 34x+85=3(13x+7)
Answer:
x=12.8
Step-by-step explanation:
34x+85=39x+21
34x-39x=21-85
-5x = -64
x = -64/-5
x = 12.8
Answer:
x = 34/5
Step-by-step explanation:
Just solve the equation
[tex]34x + 85 = 3(13x + 17)\\34x + 85 = 39x + 51\\85 - 51 = 39x - 34x\\34 = 5x\\x = 34/5[/tex]

Last year, Summerfield Steel sold 6.5×104 pounds of steel to private businesses and 2.5×105 pounds of steel to government agencies. This year, they expect to sell 3 times that amount. How much steel would that be?
Answer:
9.45 × 10⁵ pounds of steel
Step-by-step explanation:
Last year, Summerfield Steel sold 6.5×10⁴ pounds of steel to private businesses and 2.5×10⁵ pounds of steel to government agencies.
Total amount of steel sold last year = (6.5 × 10⁴ + 2.5 × 10⁵) pounds = 315000 pounds = 3.15 × 10⁵ pounds
This year, they expect to sell 3 times that amount.
This year = 3 × 3.15 × 10⁵ pounds
= 9.45 × 10⁵ pounds of steel

If you're plotting it will be (-∞,-16]
Answer:
Step-by-step explanation:
For this equation, all it is asking is to replace the unknown value with a number that completes the equation. However, the number must make the equation valid. Here is a few examples that could be a valid solution to this problem:
1. -55 + 7 < -9
(you don't need to solve this equation to tell that it's less than negative nine.)
2. 22 + (-98) + 7 < -9
(this is more complicated, but you can still tell that the sum is less than negative nine.)
So, basicly all that you have to do is replace the missing value with a number that gives the eqquation a sum less than negative nine. Hope this helped!!! :)

A snowbank that is 6 inches deep is melting at a rate of 0.5 inch per hour. Write a linear function to model the scenario and identify the domain and range of the function.
Answer:
y = -0.5x + 6, Domain [0,12] and Range [0, 6]
Step-by-step explanation:
The slope in a linear function represents the rate of change. Since the amount of snow is decreasing (indicating a negative slope) at 0.5 inches an hour, our slope would be -0.5.
Our y intercept, 6, would be the starting amount of snow. At 0 hours, no snow has been melted.
Our domain is [0,12] these are the x values from where at zero there is 6 inches of snow and at 12 there is 0 inches of snow.
Finally, our range is [0,6]. Since there cannot be no more than 6 or less than 0 inches of snow, our range is [0,6]
Hope this helped!
Times are tough for Peter the Penguin and his "Hug a Penguin" business has been on the decline. Last year Peter the Penguin made $570 dollars from selling hugs. If he experienced a 20% decrease in sales how much did he make this year?
Answer:
the new sales after decrease in sales percentage this year is $456 dollars
Step-by-step explanation:
The computation of the sales made this year is shown below:
Given that
last year sales would be $570 dollars
And in this year there is 20% decrease in sales
so, the new sales after 20% decrease would be
= Last year sales × (1 - decreased percentage)
= $570 × (1 - 0.20)
= $570 × 0.80
= $456 dollars
hence, the new sales after decrease in sales percentage this year is $456 dollars
