With the b2+b- 12 your gonna want to do this
b2+b-12
b2+4b-3b-12
which is the sum product
after doing that you wanna common the factors from the two pairs. Which is b2+4b-3b-12 then you do you parentheses around b(b+4)-3(b+4) just like that after you do that then you rewrite it in factored form b(b+4)-3(b+4) you then want to rewrite it to this (b-3)(b+4) after that your solution will be (b-3)(b+4) for the first one.

$45.50
2 bags = $7
13 bags=?
7÷2=3.5
3.50=1 bag
$3.50 × 13 bags = $45.50 for 13 bags of Doritos

the relationship between the x- and y- values in each table is linear. write a function. find the amount and rate of change. (5

Doss [256]

(5)

Since, the relationship is linear

so, we can use point slope form of line and find equation of line

we can select any two points

first point is (4,10)

so, x1=4 , y1=10

second point is (7,17.5)

so, x2=7 , y2=17.5

now, we can find slope

$m=\frac{y_2-y_1}{x_2-x_1}$

now, we can plug values

$m=\frac{17.5-10}{7-4}$

$m=2.5$

now, we can use point slope form of line

$y-y_1=m(x-x_1)$

now, we can plug values

$y-10=2.5(x-4)$

we get

$y=2.5x$

Initial amount:

It is the value of y when x=0

so, we can plug x=0 and find y

$y=2.5\times 0$

$y=0$

So, initial amount is 0

Rate of change:

we know that rate of change is slope

so, m=2.5

so, the rate of change is 2.5

(6)

Since, the relationship is linear

so, we can use point slope form of line and find equation of line

we can select any two points

first point is (2,29)

so, x1=2 , y1=29

second point is (5,41)

so, x2=5 , y2=41

now, we can find slope

$m=\frac{y_2-y_1}{x_2-x_1}$

now, we can plug values

$m=\frac{41-29}{5-2}$

$m=4$

now, we can use point slope form of line

$y-y_1=m(x-x_1)$

now, we can plug values

$y-29=4(x-2)$

we get

$y=4x+21$

Initial amount:

It is the value of y when x=0

so, we can plug x=0 and find y

$y=4\times 0+21$

$y=21$

So, initial amount is 21

Rate of change:

we know that rate of change is slope

so, m=4

so, the rate of change is 4
