Answer:
multiplication property of equality
Step-by-step explanation:
Since we are multiplying by the same amount on each side, we are using the multiplication property of equality
Answer: Multiplication Property of Equality
Step-by-step explanation:
This property states that while simplifying an expression, you can multiply both sides of the equation by any number, and it will stay true. This property is useful here, because multiplying a fraction by its reciprocal = 1, so the expression would become 1x=-128.

Slope intercept form is y = mx+b where m is the slope, and b is the y intercept.
That means that our equation HAS to have y = 3x as the first part because it's the slope.
Now to find 'b'.
To find b there's two methods, and I'll be telling you both.
You can either plug (-1,-8) into the equation of y = 3x + b, or just add 3 to the -8 because you're basically trying to find the y intercept, which is at x = 0, which is just 1 unit away from -1,-8. And because you're increasing by intervals of 3 between each x unit, you just add 3 to the y value, and you have -5.
If you plug it in: -8 = -3 +b you'll get the same thing. b = -5
In this case answer choices A and D would be right.
Hope I helped :)
-3x + y = -5
y = 3x -5 (the number before x is the slope.)
So, A. so far works, because it has a slope of 3.
Now, plug in the coordinate (-1,-8)
-8 = 3(-1) - 5
-8 = -3 -5
-8 = -8
This means that A. is one of the answers!!!!!!!
B.
3x + y = -5
y = -3x - 5
This doesn't work because it doesn't have the same slope.
B. is NOT one of the answers.
C.
(y-8) = 3 (x-1)
y - 8 = 3x - 3
y = 3x + 5
So far, it does work because it has a slope of 3.
It is not the same equation as A's equation, so it doesn't work
D.
(y + 8) = 3(x + 1)
y + 8 = 3x + 3
y = 3x - 5
THIS IS THE SAME EQUATION AS A'S EQUATION SO WE KNOW IT IS CORRECT!!!!!
So, D. is also correct.
Answer: Aand D.

Answer:
B
Step-by-step explanation:
We know that all of the ages are 7 apart so we don't need to mess with that.
Since Ed's age is 3/2 times Ted's age, we can make an equation.
Ted = t
Ed = e
e = 3/2t
Now we can just substitute and see if it checks out.
21 = 1.5 * 14
And since they are equal B is the answer.

80% of a number is 80 so
0.80x=80
x=100
Final answer:
To find a value of which 80 is 80%, we set up an equation and solve for the unknown. The equation is 80 = 0.80 * X, which after solving gives X = 100.
Explanation:
The question is asking for a value of which 80 is 80%. To do this, we can form an equation based on the fact that 80 is 80% of the unknown value. Let's denote the unknown value as X. Therefore, we can write the equation as:
80 = 0.80 × X
To solve for X, we should divide both sides of the equation by 0.80. Therefore:
X = 80 / 0.80 = 100
So, the value of which 80 is 80% is 100.
