Answer:
-4
Step-by-step explanation:
In a linear equation, the terms "unit rate", "rate of change", "constant of proportionality", and "slope" all refer to the coefficient of x (the independent variable).
Here, the coefficient of x is -4.
The slope is -4.
_____
<em>Additional comment</em>
Strictly speaking the "constant of proportionality" only refers to the x-coefficient (k) when the equation is of the form ...
y = kx . . . . . with no added constant
"Slope", "unit rate", and so on, can also refer to the x-coefficient (m) when the equation has a non-zero y-intercept (b):
y = mx + b
Answer:
x = 25
Step-by-step explanation:
A segment joining the midpoints of 2 sides of a triangle is half the length of the third side, that is
x - 8 = × 34 = 17 ( add 8 to both sides )
x = 25
Answer:
49°
Step-by-step explanation:
The circumference of a circle measures 360 degrees, so arc XW is 98°.
So, angle XWY is 49°.
Answer: 19.42
Step-by-step explanation:
To find the distance, we need to use the distance formula.
With the given points, we can plug them in and solve.
[parenthesis]
[exponent]
[add]
[square root]
Now, we know the distance is 19.42.
Answer:
The amount spent on all other types of advertising is $90 billion
Step-by-step explanation:
In this question, we are asked to calculate the amount spent on all other forms of advertising given the amount spent on tv advertising and the percentage of the total that it represents.
Firstly, we need to calculate the total amount spent on advertising.
we do not know this amount, so we can call it x.
Now, mathematically;
40% of x = $60 billion
40/100 * x = 60 billion
40x = 100 * 60 billion
x = (100 * 60)/40 = 6000/40 = 150 billion
The amount spent on all other advertising = Total amount spent on advertising- amount spent on television advertising = 150 billion - 60 billion = 90 billion
