Answer: - Just a minus sign
Subtracting a positive is subtraction.
<h3>The
- changes the second (+) to a negativ </h3>
Step-by-step explanation:
Perhaps tthe point of this question would br to contrast it with
(+)-(-) becomes +
<h3>That would be
Subtracting a negative changes to addition.</h3>
Answer:
The mean is large so
Yeah u add and later divide by how many numbers there are
Median
128 and 129
Answer: 480 milligrams
Step-by-step explanation:
We can solve this by using direct proportion whereby y = kx
where,
x = patient's weight = 92 pounds
k = constant
y = milligrams of antibiotics = 320
Using y = kx
320 = 92k
k = 320/92
k = 3.4782609
The antibiotic that should be given to a patient who weighs 138 pounds will be:
y = kx
y = 3.4782609 × 138
y = 480 milligrams
The antibiotic that should be given to a patient who weighs 138 pounds is 480 milligrams.
Answer:
x = 9
Step-by-step explanation:
38 = 6x - 16
Situate the x to one side -6x = -16-38
-6x = -54
-x = -9
x = 9
Answer:
The correct option is;
a > 1
Step-by-step explanation:
An exponential function can be expressed in the following general form;
f(x) = b·aˣ + k
Where;
b = The coefficient term
a = The base
x = The exponent
k = The vertical shift
The characteristic of an exponential function is that it increases if a > 1
From the graph, we have;
As 'x' increases to the right of the graph, f(x) = aˣ increases (upwards), therefore, a > 1
