Answer:

b = 5

Step-by-step explanation:

All quadratic equations are formed in the format of a^{2} + bx + c = 0

Using this formula, we can re-arrange the equation to fit the given format.

3x^{2} - 2 = -5x
3x^{2} + 5x - 2 = 0

5 is plugged in for "b" in this equation, therefore b = 5.

Write and solve an inequality that represents the number of days driven without the warning light coming on. Explain clearly wha
marta [7]

Answer:

0.6x < 12.5

x < 20.83 days

Step-by-step explanation:

Diego's family car holds 14 gallons of fuel. Each day the car uses 0.6 gallons of fuel. A warning light comes on when the remaining fuel is 1.5 gallons or less. Write an inequality that represents the number of days Diego's father can drive the car without the warning light coming on. Explain each part of your inequality

Car fuel capacity = 14 gallons

Fuel capacity that shows warning light = 1.5 gallons

Fuel capacity without warning light = Car fuel capacity - Fuel capacity that shows warning light

= 14 gallons - 1.5 gallons

= 12.5 gallons

Fuel used per day = 0.6 gallons

Let

x = number of days Diego's father can drive the car without the warning light coming on

The inequality is

0.6x < 12.5

Solve for x

x < 12.5/0.6

x < 20.83 days

If line segment ab=7cm draw a perpendicular at a point c on line ab such the ac=3.5cm
Reil [10]

See attachment for the drawing of the perpendicular at a point c on line ab such the ac = 3.5 cm

<h3>How to draw the perpendicular at a point c on line ab such the ac = 3.5 cm?</h3>

The given parameters are:

Length of segment AB = 7 cm

Also, we have:

Point C is located on line segment AB

This means that:

Length of segment AC = Length of segment BC = 3.5 cm

When represented on a line segment, we have:

A          C          B

See attachment for the drawing of the perpendicular at a point c on line ab such the ac = 3.5 cm

Knox save $56 during the summer break. He spent 3/7 of his savings on a pair of baseball cleats. He spent 5/8 of the remaining m
iogann1982 [59]

Answer:

12 dollars

Step-by-step explanation:

He spent 3/7 of 56

3/7*56 =24

Take the original amount and subtract what was spent

56-24 =32

He has 32 left

He spent 5/8 of that on a bat

5/8 *32 =20

Take the amount of money he had and subtract what was spent

32-20 = 12

He has 12 left
