The school purchased a tablet cart and tablets for a total cost of $10,840.24. the cart cost $852.99 and the tablets cost $399.49 each. if t represents the number of tablets, which equation can be used to find how many tablets were purchased? answer choices
a. 852.99+399.49t=10,840.24
b. 852.99t+399.49t=10,840.24t
c.852.99t+399.49=10,840.24
d.852.99t+399.49=10,840.24t

part 2 how many tablets did the school purchase?
answer choices
a.0.25 b. 9 c.25 d.2,711

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

no

explanation:

you can be freinds, and people but not follow people.

ok so what's the question?

step-by-step explanation:

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
