Answer: B = 1

Step-by-step explanation: The first step is to add 6 to both sides of the equation to get -2b = -2

You then divide both sides by negative 2 so you can get a positive

dividing both sides by negative 2 will leave you with 1b = 1

b = 1

Mrs. Jones bought 6 kilograms of rice. After filling 10 containers with the same

9966 [12]

There are 514 gram rice in each container.

Step-by-step explanation:

Given,

Amount of rice = 6 kg

1 kg = 1000 g

6 kg = 6*1000 = 6000 g

Number of containers = 10

Rice left = 860 g

Let,

x be the amount in each container.

Total amount of rice - Number of containers*Amount in each container = Amount of rice left

$6000-10x=860\\6000-860=10x\\5140=10x\\10x=5140$

Dividing both sides by 10

$\frac{10x}{10}=\frac{5140}{10}\\x=514$

There are 514 gram rice in each container.

2.8y + 6 +0.2 y =5y -14

serious [3.7K]

2.8y + 6 + 0.2y = 5y - 14
(Simplify like terms in first half of equation)
3y + 6 = 5y - 14
(Subtract both sides by 3y)
6 = 2y - 14
(Flip)
2y - 14 = 6
(Add both sides by 14)
2y = 20
(Divide both sides by 2)
y=10

Please help me solve these are quadratic equations: I

julia-pushkina [17]

Answer:

$\boxed {\boxed {\sf a= 3, b=7, c=2}}$

$\boxed {\boxed {\sf Y-intercept = c }}$

$\boxed {\boxed {\sf Minimum}}$

Step-by-step explanation:

a. a, b, c

Quadratic equations in standard form are written as:

$f(x)= ax^2+bx+c$

The exponents are listed from greatest to least. The quadratic is already in this form, so match up the variables and values in the equation.

$f(x)= 3x^2+7x+2$

$a=3 \\b=7 \\c=2$

b. Y-intercept

The y-intercept for a quadratic is c.

You can also substitute 0 in for x, because the y-intercept occurs when the quadratic crosses the y-axis (at x=0).

$f(0)= 3(0)^2+7(0)+2$

$f(0)=3(0)+7(0)+2\\f(0)= 0+0+2\\f(0)=2$

We know that c=2, so the y-intercept is c.

c. Maximum/minimum

The entire quadratic is positive, so the quadratic opens up and has a minimum.
