Answer:
B
Step-by-step explanation:
In order for something to have infinite solutions, both sides need to be equal to each other.
Example:
3x + 7y = 7y + 3x
That has infinite solutions
3x + 7y = 7x + 3y
That is not equal to each other because the variables are different.

Total number of yards of ribbon available = 25 yards.
Number of yards of fabric available = 30 yards.
Number of yards of ribbon a child need = 1.75 yards
Number of yards of fabric a child need = 2.8 yards.
<em>Total number of children participate in the activity for 25 yards of ribbon = 25/1.75 = 14.28 approximately 15 children.</em>
<em>Total number of children participate in the activity for 30 yards of fabric = 30/2.8 = 10.7 approximately 11 children.</em>
<h3>Therefore, maximum 11 children can participate in the activity because each child required both 1.75 yards of ribbon and 2.8 yards of fabric .</h3>
×≥ 26/7 is the answer.
hope it helps!
We could use the formula, derive the formula, or just work it out for this case. Let's do the latter.
The distance of a point to a line is the length of the perpendicular from the line to the point.
So we need the perpendicular to 5x-4y=10 through (-1,3). To get the perpendicular family we swap x and y coefficients, negating one. We get the constant straightforwardly from the point we're going through:
4x + 5y = 4(-1)+5(3) = 11
Those lines meet at the foot of the perpendicular, which is what we're after.
4x + 5y = 11
5 x - 4y = 10
We eliminate y by multiplying the first by four, the second by five and adding.
16x + 20y = 44
25x - 20y = 50
41x = 94
x = 94/41
y = (11 - 4x)/5 = 15/41
We want the distance from (-1,3) to (94/41,15/41)
