<span>To determine whether (−1,4) is a solution to the equation 3x+8y=29, substitute ...-1... for x and ...4... and for y.
In a pair of values like (-1, 4), the first coordinate, or entry, occupied by -1 always represents x.
Similarly, the second coordinate occupied by 4 represents y.
Answer: </span>substitute ...-1... for x and ...4... and for y.
What grade is this? can you maybe break it down
Answer:
Milk $3.60
Water $1.80
Chips $0.90.
Step-by-step explanation:
If w = cost of 1 bottle of water, m = cost of 1 gal of milk and c cost of 1 bag of chips we have.
4m + 6w + 5c = 29.7
Also we have w = 2c and m = 1.8 + w.
From the first equation we have c = w/2.
So substituting for c and m in the initial equation we have:
4(1.8 + w) + 6w + 5(w/2) = 29.7
7.2 + 4w + 6w + 2.5w = 29.7
12.5w = 22.5
w = 1. 80.
So c = w/2 = 1.8/2 = 0.90.
and m = 1.8 + 1.8 = 3.60.
Answer:
The two points are (1,-4) and (1,4)
Step-by-step explanation:
Given that distance between points is 8 units.
Also, Points have the same co-ordinate of x-coordinates.
Let one point be (1,-4)
Distance between two points is given by L=
Putting into the formula,
L=8 and (X1, Y1)=(1,-4) and (X2,Y2)=(1,Y2)
Thus, the two points are (1,-4) and (1,4)
Answer:
