Idon’t really understand how to do the equation! due to tomorrow !

the equation means that overall the distance is 200 miles per a hour the car has 2 speed it travels at. Sometimes it will travel at 35 miles per a hour and sometimes it will travel at 55 miles per a hour.

Step-by-step explanation:

ex.

55(3)+35y=200

165+35y=200

35y=35

she will spend 1 hour going at 35 mph

can you add an image ?

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
