A food pantry is making packages. Each package weighs 64 pounds. Situation 1: Each package contains 4 boxes. Each box contains a 7 pound bad of beans and a bag of rice the bags of rice are all identical.
a. write an equation to represent the situation using x [ ]
b. solution to the equation x=[ ]
Situation 2: each package contains 4 identical bags of rice and a 7 pound bag of beans.
c. write an equation to represent the situtation using x [ ]
d. solution to the equation x= [ ]

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

the answer is a.

135 and 80

step-by-step explanation:

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
