Determine whether the following statement is true or false.
A proper use of units can help us to determine the meaning of the slope of a linear function.
Answers
Here we want to see if the statement:
"A proper use of units can help us to determine the meaning of the slope of a linear function" is true or false.
We will see that it is true.
First, a general linear equation can be written as:
y = a*x + b
Where a is the slope, x is the independent variable, y is the dependent variable, and b is the y-intercept.
The proper use of units is:
y and b must have the same units.
x can have any type of units
The slope must have the quotient between the units of y and the units of x.
Where the proper use of units means that we have the same units on both sides of the expression.
Now, assume that we know the units of y and x.
For example:
y is miles (then b is also in miles)
x is in hours
Then, with the proper use of units, we can see that the units of the slope are:
miles/hour, or miles per hour.
With this (only knowing the units of x and y) we can see that the slope will be a speed.
So yes, the proper use of units is really important, as this has a lot of information (particularly, the meaning of the slope in a linear equation)
Thus, the statement is true.

X/2-7=9
Show your work in details if you can, I have a hard time understanding this.
Answers
x/2-7=9
I moved the 7 to the other side of the equation
So now
X/2 = 9 + 7
X/2 = 16
Since x is equal 16 if you divide x by 2 (because x/2=16), that means if you want to find x you need to multiply x by 2
X = 16 x 2
X = 32
I hope it’s right !! <3
Answer:
Step-by-step explanation:
x/2 - 7 = 9 Add 7 to both sides
+7 7
x/2 = 16 Multiply both sides by 2
2*x/2 = 16*2
x = 32
You are at about the second stage of solving equations. So far what you should know is that you should add or subtract before doing multiplication or division.
Take a much simpler question
x - 8 = 10 What do you do here? You can't multiply or divide. So add
+8 8
x = 18
Now try what you have
2x - 5 = 11 Add before multiplication or division
5 5
2x = 16 Divide by 2
2x/2 = 16/2
x = 8

Answers
Answer:
-6
Explanation:
x= -1 and y=3
3x- y
=> 3(-1)-3 = -3-3= -6
Answer:
3x – y = -6
Step-by-step explanation:
To solve on the problem above, you can do it by substitution and elimination of the two equations.
3x + 2y = 3
➡️ 3x + 2.3 = 3
➡️ 3x + 6 = 3
➡️ 3x = -3
➡️ x = -1
➡️ 3x – y = 3(-1) – 3
➡️ = -3 – 3 = -6 ✅

Recipe for Sandwiches:
Bread = 2 slices
Mustard = 2 teaspoons
Salami = 3 slices
cheese = 2 slices
Lettuce = 2 leaves
Tomato = 1 slice
3 pounds of cheese = 16 × 3 slices = 48 slices2 loaves of bread = 20 slices × 2 = 40 slices1 quart of mustard = 4 cups × 16 tablespoons × 3 teaspoons= 192 teaspoons
lettuce = 3 heads × 15 leaves= 45 leaves

Bread = 40 slices
Mustard = 192 teaspoons
Salami = 60 slices
cheese = 48 slices
Lettuce = 45 leaves
Tomato = unlimited
Bread
Recipe available / original recipe
= 40 slices / 2 slices
= 20 servings
No leftovers
Mustard
Recipe available / original recipe
= 192/2
= 96 servings
No leftovers
Salami

human skin is about 1000 ohms. How much current passes across
someone's finger if they touch the leads of a 9 volt battery when their skin
is wet and dry?
Answers
Answer:
Step-by-step explanation:
1000 Ohms
R = 1000
V = 9
I = V / R
I = 9 / 1000
I = 0.009
500000 Ohms
V = 9
I = V/R
R = 500000
I = 9 / 500000
I = 0.000018
Margie had 4 2/5 pans of lasagna. After a party she has 1 1/2 pans left. How much lasagna was eaten at the party
Answers
Answer:
2 9/10 pans
Step-by-step explanation:
4 2/5-1 1/2=2 9/10 pans
2 and 9/10 pans of lasagna were eaten at the party.
To find out how much lasagna was eaten at the party, you need to calculate the difference between the initial amount of lasagna Margie had and the amount she has left after the party.
Initial amount of lasagna = 4 2/5 pans
Amount left after the party = 1 1/2 pans
First, we need to convert both fractions to a common denominator. The common denominator of 5 and 2 is 10.
Initial amount of lasagna = 4 x 10/10 + 2/5 x 10/10
= 40/10 + 4/10
= 44/10 pans
Amount left after the party = 1 x 10/10 + 1/2 x 10/10
= 10/10 + 5/10
= 15/10 pans
Now, subtract the amount left after the party from the initial amount to find out how much lasagna was eaten:
Amount eaten = Initial amount - Amount left
Amount eaten = 44/10 - 15/10 = 29/10 pans
You can simplify the fraction further:
Amount eaten = 2 + 9/10 pans
So, 2 and 9/10 pans of lasagna were eaten at the party.
