Answer:
Step-by-step explanation:
first find the slope
m = Δy/Δx = (-1 - (- 5)) / (4 - (-2)) = 4/6 = 2/3
Then plug either point into the equation
y - y₁ = m(x - x₁)
y + 1 = 2/3(x - 4)
which is equivalent to
y + 5 = 2/3(x + 2)
The answer is b. (-2,2)
Since it is a dilation of 2, multiply each number by 2.
-1*2=-2
1*2=2
So after the dilation, it would be (-2,2)
There are 62 dimes and 44 nickels.
N + D = 106 (There are 106 coins in all.)
1 nickel = 5 cents.
1 dime = 10 cents.
5*N + 10*D = 840 ($8.40 = 840 cents)
N + D = 106 -------(1)
N = (106 - D)
5*N + 10*D = 840 ---------(2)
5*(106-D) + 10*D = 840
530 - 5*D + 10*D = 840
5*D = 840 - 530
5*D = 310
D = 310/5 = 62
Eq(1) N + D = 106
N + 62 = 106
N = 106 - 62
N = 44
The square root of 224 is: 14.9666295471
