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.

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

the answer is c

Noah is thinking of two fractions that have a sum of 3/5 each fraction has a numerator of 1 what are the denominators of the fractions
Answer:
Step-by-step explanation:
1/2 and 1/10
The value of fractions whose sum is 3/5 are, 1/2 and 1/10.
What is mean by Fraction?A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.
We have to given that;
Noah is thinking of two fractions that have a sum of 3/5 each fraction has a numerator of 1.
Now, Let two fraction with each has a numerator of 1 are,
⇒ 1/2 and 1/10
Now, We can add these fraction, we get;
⇒ 1/2 + 1/10
⇒ (10 + 2) / 20
⇒ 12/20
⇒ 3/5
Thus, The value of fractions whose sum is 3/5 are, 1/2 and 1/10.

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

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.

Have to figure out values of x and y. pls show steps if u can
Answer:
y=60 degrees
x=90 degrees
Step-by-step explanation:
If you look at x, you can tell by it's angle that it is 90 degrees. A square has 4 sides with 90 degrees on each side, that angle is 1/4 of a square, making it a 90 degree angle, and a triangle has 3 sides, all 60 degrees, if you look at y, you can see that angle is 1/3 of a triangle, giving it a 60 degree angle.
