Mrs. Dyson works at a music camp She has $90 to spend on guitar strings for her students. A pack of bronze strings costs $6 00. A pack of nickel strings costs $450 The following equation represents her situation 6x + 4.5y = 90 How can you use the equation to find the total number of packs Mrs Dyson can buy if she only buys nickel strings?
Substitute o for y and solve for x O
Substitute o for x and solve for y O
Substitute y for x and solve for y O
Substitute x for y and solve for x​

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?

coins of silver or gold

step-by-step explanation:

1010: 3030

is it i think

it would not be increasing by nothing that i can see probably by 25 percent that is all i can sat\y for now if i have any thing else to say i will edit this.
