Step-by-step explanation:
Is this correct? If it isn’t what’s the correct answer?
Answer:
No, it is 6.60
Step-by-step explanation:
We need to know the cost of 1 pound, so we have to do 3.60 divided by 3, to get the cost of 1 pound, which is 1.20
We times 1.20 by the amount of pounds we need, (5.5,) and get 6.60.
If it was times just 5 pounds, than yes, it would be correct, but we need to look out for decimals too.
Answer:
d. $6.60
Step-by-step explanation:
3 cost 3.60, then 5.5 would cost ?
So we have to find what multiplied with 3 would equal 5.5, so:
5.5/3, we can't simplify this fraction so we'll just use it to multiply 3.60
3.60 × 5.5/3 = 19.8/3 = 6.6

Answer:
Step-by-step explanation:
If x = -5
Entonces f(X) = (-5) - 5 = -10
If x = 0
So f(x) = (0) - 5 = -5
When x = 5
So f(x) = (5) - 5 = 0
Don't pay attention to the "F", it just means they want the whole result of the operation if you replaced "x" with a number.
Remember that there are negative and positive numbers.
Any number below zero is negative.

2. If you were to graph the line y = 2x-1 using a t-chart, list the five ordered
pairs that would go in the chart shown.
Answer:
(-2, -5)
(-1, -3)
(0, -1)
(1, -1)
(2, 3)
Step-by-step explanation:
To do this you simply put in an input for x and then solve and you will get your y.
We'll use
x= -2 for this input
y=2(-2)-1
y=-4-1
y=-5
(-2, -5) Is one ordered pair
We'll use
x= -1 for this input
y=2(-1)-1
y=-2-1
y=-3
(-1, -3) Is another ordered pair
We'll use
x= 0 for this input
y=2(0)-1
y=0-1
y=-1
(0, -1) is another ordered pair
We'll use
x= 1 for this input
y=2(1)-1
y=2-1
y=1
(1, -1) is another ordered pair
We'll use
x= 2 for this input
y=2(2)-1
y=4-1
y=3
(2, 3) is the last pair I'll use today.

for two complex numbers z and w, which diagram shows the geometric representation of zw
Answer:
The answer is the last one, D, pictured above on the question, I took the test and it showed it was the right one
Step-by-step explanation:
The geometric expression of two complex number is the magnitude r₁*r₂ and the phase is θ₁ + θ₂.
What is complex number?The complex number is" the combination of real numbers and an imaginary number. The complex number is of the form a + i b".
According to the question,
z, w are the two complex numbers. The distance from its point in the complex plane to the origin (0,0) and the angle formed by the line segment from the origin to the point and the positive half of the x-axis.
The distance or 'magnitude' to the origin is denoted as 'r' and the angle or 'phase' formed denoted as 'θ'. The distance to the origin is called 'magnitude'.
The parameter 'r' and 'θ' related to 'a' along x-axis and 'b' along y-axis.
Euclidean distance formula applying Pythagorean theorem we have
r = [tex]\sqrt{a^2+b^2}[/tex].
The sine angle is defined to the ratio y-coordinate 'b' to length 'r' and the cosine angle is defined to the ratio x-coordinate 'a' to length 'r'.
sin θ = [tex]\frac{b}{r}[/tex] and cos θ = [tex]\frac{a}{r}[/tex].
b = r sin θ; a = r cosθ
When multiplying two complex numbers we by multiplying magnitude together and add two phase. when divide two complex number by dividing the magnitude correspondingly and subtracting the phase from the numerator and the denominator.
Then we have product complex number to the magnitude r₁ and phase θ₁
with a complex number to the magnitude r₂ and the phase θ₂ which gives the complex number with magnitude r₁ * r₂ and θ₁ + θ₂.
Hence, the geometric representation of z w is with magnitude r₁*r₂ and phase is θ₁ + θ₂.

Find A and B if the graph of Ax + By = 12 passes through (2, 1) and is parallel to the
graph of 2x − 7y = 3.
Answer:
A is -8
B is 28
Step-by-step explanation:
Let us rewrite the equation in the standard format of y = mx + b
By = -Ax + 12
y = (-A/B)x + 12/B
Now, since the line is parallel to the line given below, then their slopes must be equal
2x - 7y = 3
7y = 2x - 3
y = (2/7)x - 3/7
slope here is 2/7
Thus;
-A/B = 2/7
let’s now insert the point that the line passes through
We have;
1 = (-A/B)2 + 12/B
but -A/B = 2/7
1 = 4/7 + 12/B
12/B = 1 - 4/7
12/B = 3/7
B = (7 * 12)/3
B = 28
-A/28 = 2/7
-7A = 56
A = 56/-7
A = -8
A graphic designer makes a sketch for an image that will appear on a poster. The width of the sketch is 14 in. She figures that it should be enlarged to 220% to make the final image. How wide will the final image be?
A. 6.4 in.
B. 64 in.
C. 30.8 in.
D. 308 in.
Answer:
C
Step-by-step explanation:
You need to multiply 14 x 220%
220% = 2.2
So 14 * 2.2 = 30.8
Another way to think of it would be: 100% of 14 = 14
So 200% would mean you need to double that, which would be 28
Then the final 20% would add 2.8
Add 28 + 2.8 = 30.8

Graph g(x) = -2x - 3
Answer: Slope=–2, y-intercept= (0, –3), and x-intercept (–3/2, 0).
Step-by-step explanation:
Slope of the graph is -2 and y intercept is -3.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The given graph equation is g(x) = -2x - 3
g(x) equal to minus two x minus three.
By the equation of slope intercept form y=mx+c
where m is the slope and c is the y intercept.
m=-2 and c=-3
Let us plot a graph by data
x 0 1 2 3 4
g(x) -3 -5 -7 -9 -11
Hence slope of the graph is -2 and y intercept is -3.
