Answer:
see the explanation
Step-by-step explanation:
we know that
If the absolute value of the scale factor is less than 1, then the dilation produces a contraction of the original image
If the absolute value of the scale factor is greater than 1, then the dilation produces an expansion of the original image
so
<u><em>Verify each value</em></u>
1) -4


therefore
The dilation produces an expansion of the original image
2) 0.25


therefore
The dilation produces a contraction of the original image
3) -2/3


therefore
The dilation produces a contraction of the original image
4) 2.3


therefore
The dilation produces an expansion of the original image
Step-by-step explanation:
x + y = 985
2.95x + 9.95y = 7343.75
-2.95x - 2.95y = -2905.75
7y = 4438
y= 634 steak sandwiches
x + 634 = 985
x = 351 hot dogs
Equation a and equation c

If you would like to know the value of b^2 - 4 * a * c, you can calculate this using the following steps:
x * (x + 8) = 9
x^2 + 8x - 9 = 0
ax^2 + bx + c = 0
a = 1
b = 8
c = - 9
D = <span>b^2 - 4 * a * c = 8^2 - 4 * 1 * (-9) = 64 + 4 * 9 = 64 + 36 = 100
The correct result would be 100.</span>
