Answer:
5p + 4c = 20
Step-by-step explanation:
lets have p stand for the number of popcorn we buy and c stand for the number of candy we buy
you can only spend $20, so we know we need to set our equation equal to $20
now we take the price of of popcorn and multiply it p, the number of popcorn we buy. and we can do the same thing with candy.
so we end up with 5p + 4c = 20
3. An isosceles right triangle is a right triangle with congruent legs. If the length of each leg is represented by x, what algebraic expression can be used to represent the length of the hypotenuse? Explain your reasoning
please don't answer if you don't know
Answer:
Step-by-step explanation:
right triangle means Pythagorean theorem!
a^2+b^2=c^2
if each leg (a and b) = x, then
x^2+x^2=c^2
2x^2=c^2
solving for c by taking the square root of both sides leaves
c=x×sqrt(2)
c must be positive since its a length, so no need for a +- I. this case
Which equation is a point slope form equation for line AB?
y+2=−2(x−5)
y+5=−2(x−2)
y+6=−2(x−1)
y+1=−2(x−6)
Step-by-step explanation:
none of these are correct because beside the y it is a plus sign and it needs to be a minus sign but the awnser would be. y-6=-2(x-1) the way your supposed to set this up is y-y¹=slope(x-x¹) the only way their would be a addition sign in the equation is if one of the numbers in the parentheses that you put down is negative.

Find all zeros to the following polynomial function. f(x)= 5x^4 -10x^3 +4x^2 -8x.
Please answer in detailed steps I’m confused.
Answer:
Please check the explanation.
Step-by-step explanation:
Given the function
[tex]f(x)= 5x^4 -10x^3 +4x^2 -8x[/tex]
To determine the zeros, set f(x) = 0
[tex]0=\:5x^4\:-10x^3\:+4x^2\:-8x[/tex]
switch sides
[tex]5x^4-10x^3+4x^2-8x=0[/tex]
as
[tex]5x^4\:-10x^3\:+4x^2\:-8x=x\left(x-2\right)\left(5x^2+4\right)[/tex]
so the equation becomes
[tex]x\left(x-2\right)\left(5x^2+4\right)=0[/tex]
Using the zero factor principle:
[tex]\mathrm{\quad \:If}\:ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)[/tex]
[tex]x=0\quad \mathrm{or}\quad \:x-2=0\quad \mathrm{or}\quad \:5x^2+4=0[/tex]
so solving
[tex]x=0[/tex][tex]x-2=0[/tex]
[tex]x=2[/tex]
Therefore, the real zeros are:
[tex]x=0[/tex] and [tex]x=2[/tex]
[tex]5x^2+4=0[/tex] has all the imaginary zeros.
solving
[tex]5x^2+4=0[/tex]
[tex]5x^2=-4[/tex]
[tex]x^2=-\frac{4}{5}[/tex]
[tex]\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}[/tex]
[tex]x=\sqrt{-\frac{4}{5}},\:x=-\sqrt{-\frac{4}{5}}[/tex]
[tex]x=i\frac{2\sqrt{5}}{5},\:x=-i\frac{2\sqrt{5}}{5}[/tex] ∵ [tex]\sqrt{-1}=i[/tex]
Therefore, the total zeros are:
[tex]x=0,\:x=2,\:x=i\frac{2\sqrt{5}}{5},\:x=-i\frac{2\sqrt{5}}{5}[/tex]

Camila has had a collection of sports cards for several years. If the time in years since the collection started is represented by t, and the number of cards in the collection is represented by B, match each of the statements below with an equation that models the function described. Camila had started her collection with 250 cards and her collection decreased by 60 cards each year. Camila didn't have any cards when she started her collection, but her collection grew by 60 cards each year.
Answer:
1). 250 - 60t
2). 60t
Step-by-step explanation:
"Camila started her collection with 250 cards and decreased by 60 cards each year"
Starting number of cards with Camila = 250
Decrease in number of cards each year = 60
Decrease in number of cards after 't' years = 60t
Number of cards after 't' years = 250 - 60t
"Camila didn't have any card when she started her collection, but her collection grew by 60 cards each year."
Number of cards with Camila = 0
Number of cards grew each year = 60
Number of cards after 't' years = 60t + 0 = 60t
Point P is a point on a circle with center point O. Point P is also a point on PQ←→, which is tangent to circle O.
Which of the following describes the relationship between radius OP and tangent PQ←→?
A.) OP and PQ←→ are sometimes perpendicular
B.) OP and PQ←→ are always perpendicular
C.) OP and PQ←→ are never perpendicular.
D.) The relationship is dependent on the placement of point P on the circle.
The radius of the circle and tangent of the circle are perpendicular to each other. Then the correct option is B.
What is a circle?It is the centre of an equidistant point drawn from the centre. The radius of a circle is the distance between the centre and the circumference.
Point P is a point on a circle with a center point O. Point P is also a point that lies on line PQ, which is tangent to circle O.
Then the relationship between radius OP and tangent PQ will be
We know that the radius of the circle and tangent of the circle are perpendicular to each other.

22.9885 rounded to the nearest 10th
Answer: 22.9890 is the answer
Answer:
23.0 will be your answer.
Step-by-step explanation:
When you round to the nearest tenth, you go one decimal place past the decimal. This is the number that will be rounded up or stays the same.
Then we go to 1 decimal place past that one. This number determines if the number will round up or stay. If the number is 5 and greater, then it will make the number before round-up. If the number is 4 or less, then the number will stay the same.
In this case, the 8 will make the 9 round up, resulting in the 9 become a "10", and that one gets added to the 2, or the next digit to the left.

Answer:
Ten over two would be at the very right side of this number line. It would be located at the number 5. Negative nine over two would be located two segment or lines after negative five.
Step-by-step explanation:
Ten over two would come out to a positive and whole number of five. Negative nine over ten comes out so negative four wholes and one half. So this gets located two segments after negative five because it is not fully negative five but it is negative four and one half. I got these whole numbers by simplifying the numbers that we started off with. Hope you have an amazing day and do well on your assignments.

What is the equation in slope-intercept form of the line that passes through the points ( -4 , 2) and (12, 6)?
Group of answer choices
y = 0.25x − 4.5
y = 4x − 42
y = 4x + 18
y = 0.25x + 3
Step-by-step explanation:
let the equation be y = mx + b.
m = (6 - 2)/(12 - (-4)) = 1/4
sub (12, 6):
6 = 1/4(12) + b
b = 3
therefore, equation of the line is y = 1/4x + 3, aka option 4

Answer:
y = 0.25x + 3
Step-by-step explanation:
solve for slope:
(6-2)/(12+4) = 1/4
solve for b:
6 = 12(1/4) + b
6 = 3 + b
b = 3
equation can also be y = 1/4x + 3
