Answer:

12 weeks

Step-by-step explanation:

25x = 300

so 25 times what equals 300, or the amount he can spend before going under 200 in his account.

25 (times) 12 = 300

Can Someone tell me how to find a rate of change and an initial value

kow [346]

Depends on which rate of change you're talking about. The rate of change is another term for a slope of a function. There's two(2) different version of rate of change.

First version one is the instantaneous rate of change. aka derivative. This one is found simply by taking the derivative of a function.

Second version is the average rate of change, which is found using the slope formula, (y₂ - y₁)/(x₂ - x₁)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Initial value problem should give you an initial point (x, y) to plug into your function. You plug those x,y value in to find your answer.

There's variation of initial value problems so I can't give you any specific details on how to do it unless you can post the question.

You buy the following materials for the new extension. Calculate the cost of the bricks and cement and then work out the total c

bogdanovich [222]

Answer:

Cost of sand = £150

Cost of bricks = £157.5

Cost of cement = £134

Total cost = £441.50

Step-by-step explanation:

We are given that:

2 tonnes of sand is for £75.00 per tonne,

20 bags of cement are for £6.70 per bag,

350 bricks at 45p each,

So, 2 tonnes of sand at £75.00 per tonne = 2 * £75.00 = £150.00

20 bags of cement at £6.70 per bag = 20 * £6.70 = £134.00

350 bricks at 45p each = 350 * £0.45 = £157.50

Therefore, the total cost of all the materials = £150 + £134 + £157.5 = £441.50

How to solve this step by step n get the answer

lana66690 [7]

Answer:

Answer 1 :-

$\implies m_1 = -3$

$\implies y - intercept = 7$

Answer 2 :-

$\implies m_1 = -\dfrac{1}{2}$

$\implies y - intercept = -4$

Step-by-step explanation:

The Slope Intercept Form of the line is given to us . The equations given are ,

$\implies y + 3x = 7$

$\implies y + \dfrac{1}{2}x = -4$

Now we know the standard equation of slope intercept form , is

$\implies y = mx + x$

Where ,

m is slope
c is y intercept .

So , we can write about the equations as ,

$\implies y = -3x + 7$

$\implies y = - \dfrac{1}{2}x -4$

On comparing to the Standard form ,

Answer 1 :-

$\implies m_1 = -3$

$\implies y - intercept = 7$

Answer 2 :-

$\implies m_1 = -\dfrac{1}{2}$

$\implies y - intercept = -4$
