Answer:

$5 {x}^{2} - 4x - 3$

Step-by-step explanation:

$(8 {x}^{2} - 5x + 1) - (3 {x}^{2} - x + 4) \\ = 8 {x}^{2} - 5x + 1 - 3{x}^{2} + x - 4 \\ = 5 {x}^{2} - 4x - 3$

Graph the line giving one point and the slope. 2x-6y=12

koban [17]

Y = mx + c

this is the equation of line and here m is the slope

so, 2x-6y =12 can be changed into standard format

y = 2x/6 - 12/6
y=x/3 +(-2)

so, m = 1/3 , so slope will be 1/3

hope it helped :)

A car company is going to issue new ID codes to its employees. Each code will have one digit followed by four letters. The lette

scoray [572]

2734375 employee ID codes can be generated

Solution:

Given that Each code will have one digit followed by four letters

The letter V and the digits 3, 4, and 5 will not be used

So, there are 25 letters and 7 digits that will be used

Assume that the letters can be repeated

Each code = 1 digit + four letters

digits 3 , 4 , 5 cannot be used

Therefore, the remaining digits are 1, 2, 6, 7, 8 , 9, 0

7 digits that will be used

One digit can be chosen from 7 digits in 7 ways

The first letter can be chosen from 25 letters in 25 ways

Since given that letters can be repeated

The second letter can be chosen from 25 letters in 25 ways

Similarly, the third letter can be chosen from 25 letters in 25 ways

Similarly, the fourth letter can be chosen from 25 letters in 25 ways

Therefore, the total number of ways are:

$\rightarrow 7 \times 25 \times 25 \times 25 \times 25 = 7 \times 25^4\\\\ \rightarrow 2734375$

Thus 2734375 employee ID codes can be generated

Abby went to the store to buy ice cream for her party. Each box costs $3. She has a coupon for 20% off her total. If Abby buys 3

ollegr [7]

Answer: 7.2$

hope it helps :)

step-by-step explanation:

Cost of each box = 3$

Cost of 3 boxes without 20% coupon = 9$

With 20% off Coupon = 9 by 100 multiplied by 20

(the zero's cut with each other leaving)

= 9 by 10 multiplied by 2

(9 multiplied by 2 = 18)

= 18 by 10

(18 divided by 10 = 1.8)

= the 20% of 9$ is equal to 1.8

when subtracted with the total cost leaves 7.2$

Find the value of x. Enter only the number.

Sophie [7]

Answer: 5

Step-by-step explanation: These two triangles are similar triangles. Since they are similar, they must be scaled equivalently. The scale factor is 5. To know this, 3 times 5 is 15, and being equivalent, we can figure 5 times 5 is 25. Therefore x is 5. That also means that the scale factor of the smallest triangle to the biggest triangle is 5. Thus, x is 5.
