Answer:

y = -5x - 3

Step-by-step explanation:

Slope intercept form is y = mx + b, where m=slope, b=y-intercept.

y = mx + b

Slope equals -5:

y = -5x + b

Y-intercept equals -3:

y = -5x - 3

You are making several purchases from the I.B. Electric electronics store. You can buy from this store online or in a physical s

Answer:

Online store will save the most money

Step-by-step explanation:

Amount used in Physical store

Batteries 2packs @$5.99 cost = $5.99*2=$11.98

Stereo 1 system @$100 cost = $100*1=$100

CDs 3 CDs @$7.95 cost = $ 23.85

Total cost= $11.98+$100+$23.85= $135.83

Applying the 10% off coupon = 90/100 * $135.83 =$ 122.25

Applying sale tax 5% = 105/100 * 122.25=$128.36

Amount to spend when using physical store= $128.36

Now calculate for the online store

Batteries 2packs @$4.99 cost= $4.99*2=$ 9.98

Stereo 1 system @$90 cost= $ 90 *1= $90

CDs 3 CDs @$8.95 cost = $8.95*3=$26.85

Total cost=$9.98+$90+$26.85=$126.83

Applying the 5% off coupon= 95/100*126.83=$120.49

Applying the sale tax, $6.99+$120.49=$127.48

Comparing the two ways,

Physical store= $128.36

Online store=$127.48

Online store will save the most money by ($128.36-$127.48)=0.88

Can you order these please?

Nadusha1986 [10]

By making each of these a decimal, it's easier to see which are bigger or smaller

2.1, 2 2/5, 2 1/2, 2.6, 2.95

2 2/5 = 2.4
2 1/2 = 2.5

What are the solutions to the equation x² = 625?

Hoochie [10]

The correct answer would be B. Because if you multiply -25 * -25 (because the x has 2 to the second power) the answer would be 625 :)
Hope I helped.

Factor by Grouping.

Komok [63]

Answer:

The ac product of $35x^2+41x+12$ is 420.

The factors of the ac product that add to 41 are 20 and 21.

$35x^2+41x+12 =$ $(7x+4)(5x+3)$

Step-by-step explanation:

1) The general form of a quadratic is $ax^2 + bx + c$ . Hence, multiplying 35 by 12 gives you the product of ac, which is 420.

2) We need to find two numbers that multiply to 420 and add up to 41 simultaneously. If we pull out the factors of 420, two of them will be 20 and 21, which multiply to 420 as well as add up to 41.

3) Write $41x$ as a sum.

$35x^2+20x+21x+12$

Now, we can factor them out by grouping.

$35x^2+20x+21x+12\\5x(7x+4)+3(7x+4)$

Since, $7x +4$ is common in both of the factors, we only take one of the $7x+4$ along with $5x$ and $3$ .

$(7x+4)(5x+3)$
