Answer:
The correct answer is B) (x - 5)(x + 10)
Step-by-step explanation:
The constants at the end of the parenthesis need to add to the middle term
10 + -5 = 5
And they need to multiply to the end term
-5 * 10 = -50
This makes it the correct choice.
Answer:
D) 10
Step-by-step explanation:
The slope of the line y=10x+3 is 10 because in the slope form y=mxtb m represents the slope. In this case 10 is m, therefore the slope is 10. This mean the slope rises 10 units and runs 1 unit since slope is also known as rise/run.
Answer:
Each person will pay $ 7.20
Step-by-step explanation:
First we find the total bill
Pizza $18.60
Salad $2.50
<u>Soda $2.25</u>
Total $ 23.35
Sales Tax would be= 8 1/4% of $ 23.35 =$ 1.926= $ 1.93
Tip = 15% of $ 23.35= $ 3.5025
Total Bill paid= $ 23.35 + $ 1.93+ $3.50= $ 28.7825 or $ 28.78
Now dividing the bill among 4 persons = $ 28.78/4= $ 7.196 or $ 7.20
Paying the bill equally is better and convenient than paying alone as each person gets an equal share of pizza, salad and the soda.
Answer: 3(x+4)=x+18
Step-by-step explanation: Break down the problem. It says three times the sum of a number and 4. You have to add the number and 4 first. Since you're multiplying by 3, put the sum of a number and 4 in parentheses. This equals the same as eighteen more than the number. It set up how it sounds. Add 18 to the number.
