Which inequality can be used to represent this problem? A company spent 2000 developing a waterproof fabric. The company makes $3 on the sale of each yard of fabric after subtracting manufacturing costs. How many yards of fabric , x , will they need to sell to have a profit of at least $12,000 A 3x + 12000 ≥ 2000 B 3x — 2000 > 12000 C 3x + 12000 > 2000 D 3x — 2000 ≥ 12

The isosceles triangle has two sides of equal length, a, that sre longer than the length of the base ,b. the equation 2a+b=15.7 can be used to find the sides length. if one of the longer sides is 6.3 centimeters what is the length of the base

Which mathematical statements are true? 1) if 3 is an odd number, then 3 times 3 is an even number. 2) if 6 is less than 7, then 4 is greater than 7. 3) six is divisible by 3, and 10 is a multiple of 2. 4) the average of the data is greater than the largest value in the data, or it’s less than the largest value in the data. 5) the slope of a linear graph is its rate of change, and the graph’s y-intercept is the initial value. 6) if an equilateral triangle has equal angles, then all its angles will measure 45°.

[10 points, algebra 2]according to my answer key the restrictions are -1 and 4. but why not positive 1?
