Answer:
(2x−5)(x−3)
Step-by-step explanation:
Break the expression into two groups
(2[tex]x^{2}[/tex]-5x) + (-6x+15)
Factor out an x from the first group
x(2x-5)
Factor out -3 from the second group
-3(2x-5)
Factor out the common term and combine
x(2x-5)-3(2x-5)
(2x-5)(x-3)
If g(x) = 2(x − 4), find the value of x if g(x) = 20
Answer:
x = 14
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
-11x - 7y = -56, solve for y (must be in form y = mx + b)
Answer:
y= -11/7x+8
move variables to the right hand side and change its sign
-7y=-56+11x
change the signs on both sides of the equation
7y=56-11x
divide both sides by 7
y=8-11/7 x
reorder the terms and get y= -11/7x+8
Lucy runs at an average speed of 3.5 miles per hour. John runs 2 miles per hour faster than Lucy. How far will John run (r) he runs x number of hours?
Answer:
It is 5.5 miles/hour if you are trying to figure out how fast john runs.
Step-by-step explanation:
if john run 2 mile/hour faster than lucy, you just have to add how fast lucy is running by 2. This will equal john's miles/hour. now you times 5.5 by how many hours he runs.

Monarch butterflies migrate from Canada to Mexico every fall. It is estimated that the butterfly travels about 82 km each day. Suppose the butterfly travels from Edmonton to El Rosario. This is a distance of about 3936 km. How many days does it take? How did you decide which operation to use?
Given:
Butterfly can travels = 82 km each day.
Total distance = 3936 km.
To find:
The number of day it takes to travel the given distance.
Solution:
Let the number of days it takes to travel be d.
Butterfly can travels about 82 km each day.
So, distance traveled by it in d days = (82d) km
Total distance is about 3936 km.
[tex]82d=3936[/tex]
To isolate d , we need to divide both sides by 82.
[tex]\dfrac{82d}{82}=\dfrac{3936}{82}[/tex]
[tex]d=48[/tex]
Therefore, the required number of days is 48.

Step-by-step explanation:
1). [tex]8\frac{1}{4}[/tex] ÷ [tex]\frac{3}{4}[/tex]
= [tex]\frac{33}{4}[/tex] ÷ [tex]\frac{3}{4}[/tex]
= [tex]\frac{33}{4}\times \frac{4}{3}[/tex]
= 11
2). [tex]3\frac{1}{3}[/tex] ÷ [tex]\frac{10}{3}[/tex]
= [tex]\frac{10}{3}[/tex] ÷ [tex]\frac{10}{3}[/tex]
= [tex]\frac{10}{3}\times \frac{3}{10}[/tex]
= 1
3). [tex]\frac{5}{4}[/tex] ÷ [tex]\frac{1}{4}[/tex]
= [tex]\frac{5}{4}\times \frac{4}{1}[/tex]
= 5
4). [tex]\frac{25}{4}[/tex] ÷ [tex]6\frac{1}{4}[/tex]
= [tex]\frac{25}{4}[/tex] ÷ [tex]\frac{25}{4}[/tex]
= [tex]\frac{25}{4}\times \frac{4}{25}[/tex]
= 1
5). [tex]11\frac{1}{4}[/tex] ÷ [tex]\frac{9}{4}[/tex]
= [tex]\frac{45}{4}[/tex] ÷ [tex]\frac{9}{4}[/tex]
= [tex]\frac{45}{4}\times \frac{4}{9}[/tex]
= 5
6). [tex]3\frac{1}{7}[/tex] ÷ [tex]\frac{2}{7}[/tex]
= [tex]\frac{22}{7}[/tex] ÷ [tex]\frac{2}{7}[/tex]

!brainlisest! Find the value of y in the diagram.
Answer:
y=8
Step-by-step explanation:
The two triangles are similar, but scaled to a ratio.
Given the ratio of two corresponding sides AC and NL, the scale is 10:5 which is 2. So, the side MN when scaled to the same ratio, the corresponding side's length y = 4*2 = 8 ft

Select all the sequences of reflections that produce an image equivalent to the image r(180°, O)(△BCD).
Answer:
r(180°,0) is a rotation of 180° degrees over the origin.
Notice that this rotation moves our figure to the opposite quadrant (so a translation of two quadrants).
Then this is equivalent to:
A reflection over the x-axis followed by a reflection over the y-axis.
Or.
A reflection over the y-axis followed by a reflection over the x-axis.
There is another possible reflection, but it depends on where is our figure.
If the figure is in the first or third quadrant, a reflection over the line y = -x is equivalent to the rotation.
If the figure is in the second or third quadrant, then the reflection over the line y = x is equivalent to the rotation.
We can combine those two and write:
A reflection over the line y = (-1)^n*x.
Where n is the number associated with the quadrant where the figure is in.
