Brian received 45 trading cards from his mother and 25 trading cards from his uncle to start a collection.
Each week, Brian uses his allowance to buy a new pack of 15 trading cards to add to his collection.

Write an equation in slope-intercept form to represent the situation. Use x for the independent variable and y for the dependent variable. Identify what both variables represent.

Answers

Answer:

The representation of Brian's situation in slope intercept form is:

y= 15x +70

Step-by-step explanation:

Let x be the number of weeks Brian started his collection.

y be the number of cards Brian has at present.

y= 45+25+ 15 x

or, y= 15 x +70

which is in the form of,

y= mx +c (slope intercept form)

where,

m= slope

x= x- intercept

c= constant.

top and bottom: each is 3 x 2 = 6 square cm, times 2 = 12 square cm.

two sides are 6 x 3 cm = 18, times 2 = 36 square cm

other two sides are 6 x 2 cm = 12, times 2 sides = 24 square cm

Add them all up: 12 + 36 + 24 = 72 square cm

slope-intercept formula(substitute 81 for x, 112 for y, and 2 for m:

y=mx+b

112=2(81)+b

112=162+b

Then subtract 162 from both sides, and b=-50

Plug in all numbers into original equation

y=mx+b m=2 b= -50

So u get y=2x-50

The types of hamster offspring could form if The common hamster has 20 chromosomes Golden hamster, gray dwarf hamster, Chinese hamster, winter white dwarf hamster, roborovski dwarf hamster. So the number is 5.

What is chromosomes?

A chromosome is a lengthy DNA molecule that contains all or a portion of the genetic code for an organism. The histones, which are the most significant of these proteins in eukaryotic cells, coat the very long, thin DNA fibers in most chromosomes.

Given:

The common hamster has 20 chromosomes,

The 22 chromosomes that make up the Chinese hamster chromosome set are divided into 10 pairs of autosomes and XY sex chromosomes. For mouse-like rodents, it is unusual to have a karyotype combination of different-sized metacentrics and acrocentrics (Myomorpha).

The types of hamster offspring could form, is 5.

The x-intercept is the point on the x-axis where the line crosses it. The y-coordinate of the line's x-intercept is always zero. The x-coordinate of the x-intercept is the number where it crosses the x-axis. A line with an x-intercept of (5,0) crosses the x-axis at the number 5. A line with an x-intercept of (-5,0) crosses the x-axis at -5. Which of these coordinates could be a line’s x-intercept?

Answers

Answer:

D. (-7,0)

Step-by-step explanation:

If The two intercets are (5,0) and (-5,0) then (-7,0) will be an x-intercept.

Answer:

d.(-7,0)

Step-by-step explanation:

'd' is the correct answer because just as how the y-intercept has to look something like this: (0,5) as in the given 'x' point is 0 the x-intercept has to look the exact same as well (other than the fact that it's now the x-intercept instead of y.) so it would have to be that the x-axis' point can be any number that isn't 0 and the y-axis' point must always be 0.

good luck :)

Answers

Answer:

It equals 97°

Step-by-step explanation:

The mistake she made was she thought angle t was vertical to angle u and thus it has the same value. Vertical angles have to be across from each other and not on top of each other. So why does it equal 97? If we look at angle y it has the same value and the angles are exactly the same. Look below for the other explanation since it can't really be said by words.

Answer:

a and c

Step-by-step explanation:

so we know that -2 is the greatest number in this inequality and with that, the 'equation' would look like this-

x<-2

now let us solve a-d-

0.25-2.50=-2.50

-4.25-(-2.75)=-1.5

-3.25-1.75=-5

-4.50-(-5.25)=0.75

**with negative numbers the 'smaller' the number is the greater it actually is ex. -2.50<-1** it works this way because the 'larger' the number gets the further away it becomes from 0 or whole numbers making it smaller than the negative numbers closer to zero such as -1**

hopefully, that makes sense

now let us see which equations fit our inequality- **we'll let the bolded ones mean that they fit the inequality**

a)-2.50<-2

b)-1.5<-2

c)-5<-2

d)0.75<-2

good luck :)
