7 0

Answer:

x =7, y = 0

Step-by-step explanation:

2x - 9y = 14...(1) \\  \\ x =  - 6y + 7...(2) \\  \\ from \: equation \: (1) \: and \: (2) \\  \\ 2( - 6y + 7) - 9y = 14 \\  \\  - 12y + 14 - 9y = 14 \\  \\  - 21y = 14 - 14 \\  \\  - 21y = 0 \\  \\ y =  \frac{0}{ - 21}  \\  \\ \huge \red{ y = 0} \\  \\ x =  - 6 \times 0 + 7 \\  \\ x = 0 + 7 \\  \\  \huge \purple{x = 7}

A race car is driven around a circular track at a constant speed of 180 miles per hour. If the diameter of the track is 1/2 mile
velikii [3]
F the diameter is 1/2 mile, that is 0.5 mile, then the radius is 0.25 -half of it!

the angular speed is theta/time, which means

 w=theta/time

but another formula for it is Velocity*radians

w=velocity*radians

velocity is 180 mph and radians are (revolution/2 radius), that is:

w=180*(1/2*0.25)
and if we calculate this, we have: w=114.59, which is the correct answer!

Eva is picking fruit at a farm. The fees are $5 for entry to the farm, $2.50 per pound of blueberries, and $2 per pound of apple
olasank [31]

Answer:

The required expression is: y = 5 + 2.50b + 2a

Step-by-step explanation:

Given

Entry = \$5

Blueberry = \$2.50

Apple = \$2

Required

Write an expression for this scenario

If 1 pound of blueberry cost $2.50

then b pounds = 2.50 * b

If 1 pound of apple cost $2

then a pounds = 2 * a

The required expression (y) is then calculated as

y = Entry\ Fee + Blueberry = Apple

y = 5 + 2.50 * b + 2 * a

y = 5 + 2.50b + 2a

Hence, the required expression is: y = 5 + 2.50b + 2a
