X- int : (1,0)
y-int: (0,-2)

to find x-int plug in 0 for y
0= (x-1)2
Solve for x
2x-2=0
2x= 2
x=1

to find y-int plug in 0 for x
y=(0 - 1) 2
y= (-1)2
y= -2

Answer:

$\mathsf {y =\frac{15}{7}x }$ < $\mathsf {y=\frac{13}{6}x }$ < $\mathsf {y=\frac{11}{5}x }$ < $\mathsf {y=\frac{21}{9}x }$ < $\mathsf {y= \frac{19}{8}x}$

Step-by-step explanation:

<u>Finding the unit rate of the graph</u> :

Take 2 points and find the slope
⇒ (0,0) and (12, 25)
⇒ m = 25 - 0 / 12 - 0
⇒ m = <u>25/12</u>
The equation is : <u>y = 25/12x</u>

Now, the equations with greater unit rates (in increasing order) are :

$\mathsf {y =\frac{15}{7}x }$ < $\mathsf {y=\frac{13}{6}x }$ < $\mathsf {y=\frac{11}{5}x }$ < $\mathsf {y=\frac{21}{9}x }$ < $\mathsf {y= \frac{19}{8}x}$

The polynomial 8x2 – 8x + 2 – 5 + x is simplified to 8x2 – gx – h. What are the value of g and h?

igor_vitrenko [27]

Answer:

Option D: g = 7 and h = 3

Step-by-step explanation:

The polynomial is;

8x² – 8x + 2 – 5 + x

Simplifying this gives;

8x² - 7x - 3

If this is simplified to 8x² – gx – h

Thus, by comparison of terms;

– gx = - 7x

-x will cancel out to get;

g = 7

Similarly, - h = - 3

Thus,h = 3

Therefore; g = 7 and h = 3

In a certain year, the population of Smallburg was $4{,}000.$ In the following year, the population increased by $15\%.$ What wa

makkiz [27]

Answer:

4,600

Step-by-step explanation:

To solve this problem, we need to multiply add 15% of 4,000 back to 4,000.

First, change 15% into a decimal:

15% -> $\frac{15}{100}$ -> 0.15

Next, multiply 4,000 by 0.15:

$x= 4,000(0.15)$

$x=600$

The last step is to add the 600 back to 4,000:

$4,000 + 600 = 4,600$

The population of Smallburg the following year was 4,600.
