Use of distributive property will be
(30 x 5) + (9 x 5)

21. the error for x - 28 = 375 is not 347 is because the student subtracted both sides by 28. 347 - 28 is 319 not 375. One must add 28 to both sides of -28 and 375. The -28 and 28 is zero. 375 + 28 = 403.

22. The next three terms are 0.93, 1.02, and 1.11. The rule in the number pattern is one must add 0.09.

You order plant seeds from a catalog. Each packet cost 0.90 each. The shipping charge is 2.50. If you have 18.50 to spend, how m
kramer
<h2>Answer:</h2>

17

<h2>Step-by-step explanation:</h2>

Cost per Packet * Number of Packets + Shipping =  Amount to Spend

0.90 * b + 2.50 = A

You can spend a maximum of $18.50

A < 18.50

Rearrange the formula to find b

Number of Packets  =  Amount to Spend - Shipping / Cost per Packet

18.50 - 2.50 = 16.00 / 0.9 = 17.7...

You can't have 0.7 of a packet so you have to round down to 17.

Now if you put it into the original formula:

0.90 * 17 + 2.50 = 17.80

And 17.80 is less than 18.50.

Ray needs help creating the second part of the coaster. Create a unique parabola in the pattern f(x) = (x − a)(x − b). Describe
MatroZZZ [7]

Answer:

1) The parabola equation faces up

2) The y-intercept = a·b

3) The zeros are x = a and x = b

Step-by-step explanation:

1) The given information are;

f(x) = (x - a)·(x - b) which gives;

f(x) = x² - (b+a)·x + a·b

For an equation of the form a·x² - b·x + c, if a is positive, then the parabola faces up, therefore, the parabola equation, x² - (b+a)·x + ab where a is equivalent to +1 faces up

2) The y-intercept is given at x = 0, which gives;

f(0) = 0² - (b+a)·0 + a·b

The y-intercept = a·b

3) From f(x) = (x - a)·(x - b), when f(x) = 0, we have either;

(x - a) = 0 or (x - b) = 0

Therefore;

The zeros are x = a and x = b
