Answer:
D. The graph of this equation can be any straight line.
Step-by-step explanation:
Because A ≠ 0, it can be any number above or below 0.
Because B = 0, the line can only be a horizontal line. The line can be at any point on a graph, though, because A does not have any specific number that it equates to.

About 3.9 x 10^7 people live in California. About 1.3 x 10^6 live in Maine. About how many times more people live in California than live in Maine?
- 3 times as many
- 30 times as many
- 300 times as many
- 3 x 10^6 times as many
Divide the number of people in California (3.9x10^7) by the number of people in Maine (1.3x10^6)
(3.9x10^7) / (1.3x10^6) = 30

What is the slope of the line?
Answer:
In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. Slope is often denoted by the letter m; there is no clear answer to the question why the letter m is used for slope, but its earliest use in English appears in O'Brien (1844) who wrote the equation of a straight line as "y = mx + b" and it can also be found in Tod hunter (1888) who wrote it as "y = mx + c".
Step-by-step explanation:
Steps for Graphing a Line With a Given Slope
Plot a point on the y-axis. (In the next lesson, Graphing with Slope Intercept Form, you will learn the exact point that needs to be plotted first. For right now, we are only focusing on slope.)Look at the numerator of the slope. Count the rise from the point that you plotted. If the slope is positive, count up and if the slope is negative, count down.
Look at the denominator of the slope. Count the run to the right.
Plot your point.
Repeat the above steps from your second point to plot a third point if you wish.
Draw a straight line through your points.

Step-by-step explanation:
Answer:
[tex]\dfrac{-x^2-3x+46}{x^2+4x-32}[/tex]
Step-by-step explanation:
You want the simplified form of the rational expression difference ...
[tex]\dfrac{6}{x^2+4x-32}-\dfrac{x-5}{x-4}[/tex]
Common denominatorBoth terms can be expressed using the same denominator, then summed.
[tex]\dfrac{6}{x^2+4x-32}-\dfrac{x-5}{x-4}=\dfrac{6}{(x-4)(x+8)}-\dfrac{(x-5)(x+8)}{(x-4)(x+8)}\\\\\\=\dfrac{6-(x-5)(x+8)}{(x-4)(x+8)}=\dfrac{6-(x^2+3x-40)}{(x-4)(x+8)}=\boxed{\dfrac{-x^2-3x+46}{x^2+4x-32}}[/tex]

Additional comment
The process is fundamentally identical to finding the difference of numerical fractions. The least common denominator is found by considering factors of the denominators, just as it would be if they were pure numbers.

Select all expressions that are equivalent to 5x - 15 - 20x + 10.
A. 5x – ( 15 + 20x ) + 10
B. 5x + -15 + -20x + 10
C. 5 ( x-3 - 4x + 2 )
D. -5 ( -x + 3 + 4x + -2 )
E. -15x - 5
F. -5 ( 3x + 1 )
[MA]:
-5 (3 x + 1)
The explanation:
Simplify:
(5 x - 20) + (10 - 15)
Grouping like terms, 5 x - 20 x - 15 + 10 = (5 x - 20 x) + (10 - 15):
(5 x - 20 x) + (10 - 15)
5 x - 20 x = -15 x:
- 15 x + (10 - 15)
10 - 15 = -5:
-5 - 15 x
Factor: -5 out of -15 x - 5:
Answer: -5 (3 x + 1)

A car can travel 476 miles on 14 gallons of gas. How far can the car travel on 20 gallons of gas?
Answer:
680 Miles
Step-by-step explanation:
You divide 14 into 476 so you can get the answer for one gallon of gas is however many miles. In this case 1g=34ml. Then you multiply 34 and 20 and you get 680 miles.

It takes Krys and Glen 1_4hour to walk a mile. This week Krys walked 9 miles and Glen walked 3 miles. How much longer did Krys walk than Glen?
Answer:
Krys walked 1 1/2 hours longer than Glen.
Step-by-step explanation:
Glen walked 3 miles
3 x 1/4 = 3/4
Krys walked 9 miles
9 x 1/4 = 9/4
9/4 - 3/4 = 6/4
6/4 = 1 2/4
1 2/4 = 1 1/2

Which is the best statement of the angle-angle similarity theorem?
A. When the preimage of a triangle is a dilation of the image, the triangles are similar.
When triangles have two pairs of corresponding angles that are congruent, the third pair of angles is also congruent.
B. When triangles have two pairs of corresponding angles that are congruent, those triangles are similar.
C. When the interior angles of a polygon sum to 180 degrees that polygon is a triangle.
The best statement of the angle-angle similarity theorem is (a) When the preimage of a triangle is a dilation of the image, the triangles are similar.
How to determine the similarity statement?The angle-angle similarity theorem is used in similar triangles; especially when a triangle is dilated (i.e. resized) to form another triangle
When triangles are dilated, the corresponding angles in both triangles (i.e. the image and the pre-image) are always equal
Hence, the best statement of the angle-angle similarity theorem is (a)

someone help me with this i’ll mark u brainlist or whatever its called lol
he tables show the numbers of white and yellow flowers Cara and Hector used in 5 different arrangements.
Cara’s Flower Arrangements
White 3 6 9 12 15
Yellow 5 10 15 20 25
Hector’s Flower Arrangements
White 4 8 12 16 20
Yellow 6 10 14 18 22
Part A
Are the numbers of white and yellow flowers in Cara’s arrangements proportional?
Which equation relates the number of white flowers, w, to the number of yellow flowers, y?
Yes; y=35w
Yes; y=53w
No; y=3w+5w
No; y=5+3w
Part B
Are the numbers of white and yellow flowers in Hector’s arrangements proportional?
Which equation relates the number of white flowers, h, to the number of yellow flowers, e?
Yes; e=32h
Yes; e=23h
No; e=h+2
No; e=h−2
Answer:
A.
1. no, y = 5 + 3w
B.
no, e = h + 2
Step-by-step explanation:
Using the principle of proportional relationship to model the two tables, we can infer that, the first first table is proportional while the second isn't.
Clara's arrangement :
White (w)Yellow (y)Testing if relationship is proportional :
y = kw5 = 3k
[tex] k = \frac{5}{3}[/tex]
Yes, the relationship is proportional [tex] y = \frac{5}{3}w[/tex]
Hector's arrangement :
White (h)Yellow (e)The number of yellow flowers surpasses the number of white flowers by a constant value of 2.
Hence, the relationship can be modeled thus ;
e = h + 2Therefore, the relationship is not proportional.
