BRAINLIEST: the Spanish club sold homemade tamales to raise money for field trips their goal was to raise $400. on the first day, they made $100 the second day their sales totaled $143 how much money did the Spanish club need to make to reach their goal after the first two days of sales?

Answer:

a) 10.5

b) 25.32

Step-by-step explanation:

Plug in 2.3 for n in both equations.

First equation:

5 (2.3 - 2) + 9

5 (0.3) + 9

1.5 + 9

10.5

Second equation:

8 (2.3^2) - 17

8 (5.29) - 17

42.32 - 17

25.32

Step-by-step explanation:

For every increase in the x-value by 1,

the y-value decreases by -2.

(From 3 to 1 and from 1 to -1)

Hence, slope of line k

= Rise/Run = (-2)/1 = -2. (A)

Using it's formula, it is found that the slope of line k is of -2, hence option A is correct.

Given two points (x,y) on a line, the slope is given by the change in y divided by change in x.

In this problem, two of the points are: (1,3) and (2,1).

Hence, applying the division:

[tex]m = \frac{1 - 3}{2 - 1} = -\frac{2}{1} = -2[/tex]

The slope of the line is of -2, hence option A is correct.

1,15 is not the same ratio of 2,24

Answer:

No, because 1:15 is not the same ratio as 2:24.

Step-by-step explanation:

2/24 reduces to 1/12 not 1/15 so these ratios are not the same.

Answer:

h=200

Step-by-step explanation:

h/10+5=25

h/10=20

h=200

h/10 + 5 = 25

Subtract 5 from each side to get h/10 alone.

h/10 + 5 - 5 = 25 - 5

h/10 = 20

Multiply both sides by 10 to get h alone.

h/10 • 10 = 20 • 10

h = 200

h = 200. I hope this helps!

==========================================

Explanation:

1/2 = 0.5

Every 60 days, the amount cuts in half.

We start with 904 grams and after 60 days, we have 904*0.5 = 452 grams left over.

After another 60 days, we have 452*0.5 = 226 grams left over.

-------------

Alternative Method:

We can apply the half-life formula.

y = a*(0.5)^(x/H)

where,

In this case,

When x = 120 days go by, we have....

y = a*(0.5)^(x/H)

y = 904*(0.5)^(x/60)

y = 904*(0.5)^(120/60)

y = 904*(0.5)^(2)

y = 904*(0.25)

y = 226 grams of antimony left over.

This method is preferred over the first method if you have x be some non-multiple of 60, or if x is fairly large.

Answer:

15x^2-14x-4

Step-by-step explanation:

(8x^2 * x-7x+2)+(7x^2 -7x-6)

you take out the parentheses

you add the common ones so -7x+-7x= -14x

8x^2 +7x^2 = 15x^2

and 2-6= -4

so in total it's 15x^2-14x-4

Answer: 11x^2 -16x-3

Step-by-step explanation:

Solution:

Your problem → (8x^2-7x+2) + (3x^2-9x-5)

(8x2-7x+2)+(3x2-9x-5)

=8x2-7x+2+3x2-9x-5

=8x2+3x2-7x-9x+2-5
