Find the product of 51 and -2.5. Use the distributive property to rewrite and solve. The first step is done for you. 51(-2.0) + 51(-0.5) What is the next step in using the distributive property to solve this equation?
Answer:
-12.75
Step-by-step explanation:
Find the product of 51 and -2.5. Use the distributive property to rewrite and solve.
The next step using Distributive property is to expand the brackets
5.1 × 2.5
Step 1: Distributive property
51(-2.0) + 51(-0.5)
Step 2: Expand the brackets
-10.2 + -2.55
Step 3
- 12.75
Answer:
-12.75
The next step using Distributive property is to expand the brackets
5.1 × 2.5
Distributive property
51(-2.0) + 51(-0.5)
Expand the brackets
-10.2 + -2.55
- 12.75

Solve (y-4)^2+63=0 where y is a real number.
Answer:
[tex] y = 4 + 3 \sqrt{7} i[/tex]
Step-by-step explanation:
[tex](y-4)^2+63=0 \\ \\ (y-4)^2 = - 63 \\ \\ (y-4)= \sqrt{ - 63} \\ \\ y - 4 = 3 \sqrt{7} i \\ \\ y = 4 + 3 \sqrt{7} i[/tex]
Which of the following tables does not repesent a function
Answer:
C
Step-by-step explanation:
It's not A because 7 is being repeated for y more than once. It's not B because 5 has been repeated more than once for y. It's not D because 7 is being repeated more than once for x. If you look at C, you can see that no numbers are being repeated for x, and no numbers are being repeated for y.

The value of a new car decreases by about 15% in the first year. How much will a car be worth after one year if its initial value was $1,500? If you get stuck, consider using diagrams or a table to organize your work.
Answer:
After one year, the car will be worth $1,275.
Step-by-step explanation:
We know that a new car value decreases by 15% every year. So, we first need to find 15% of $1,500.
1,500 x 0.15 = $225.
Now, me must subtract $225 from the initial value, or $1,500.
1,500 - 225 = $1,275
Therefore, after one year, the car will be worth $1,275.
Hope this helps! :D

Larissa takes a dose of 4 drops of medicine every day, three times a day. One milliliter (mL) of the medicine contains about 20 drops. If the medicine comes in a 12 mL bottle, approximately how many days will the bottle last?
Answer:
The bottle will last for 20 days.
Step-by-step explanation:
Given that:
Number of drops in a dose = 4 drops
Dose is taken three times a day, therefore,
Number of drops taken in a day = 4*3 = 12 drops
One milliliter = 20 drops
12 mL = 20*12 = 240 drops
Number of days the bottle will last can be find out by calculating total number of drops by the number of drops consumed in a day.
Number of days bottle will last = [tex]\frac{240}{12}=20[/tex]
Hence,
The bottle will last for 20 days.
Determine the output if the function rule is
2x+5 : input = 5
Answer:
2x
Step-by-step explanation:
Answer:
15
Step-by-step explanation:
The input is 5 , the output is the value of 2x + 5 for x = 5 ( input ), that is
output = 2(5) + 5 = 10 + 5 = 15
Solve the inequality 7x - 11 < 9x + 22.
Answer:
x>-33/2
Step-by-step explanation:
this is because you must solve the equation. when you divide by a negative number in order to get the x alone the sign of the inequality flips.
Answer:
[tex]x > \frac{ - 11 - 22}{2} [/tex]
Step-by-step explanation:
Step 1: Subtract 7x7x from both sides.
−11<9x+22.−7x
Step 2:Simplify 9x+22.-7x9x+22.−7x to 2x+22.2x+22.
−11<2x+22.
Step 3:Subtract 22.22. from both sides.
−11−22.<2x
Step 4:Divide both sides by 22.
[tex] \frac{ - 11 - 22}{2} < x[/tex]
Step 5, Switch sides.
[tex] x > \frac{ - 11 - 22}{2} [/tex]
I hope it helps you.

Solve the quadratic equation: x^2+ 2x + 7 = 21
Answer:
x1 = -4.872983346
x2 = 2.872983346
Step-by-step explanation:
Given:
x^2+2x+7=21
Subtract 21 on both sides to get the right side equal to 0:
x^2+2x-14=0
Use the quadratic formula:
x1 = -4.872983346
x2 = 2.872983346

Is xy = yx? Explain how you know
Answer:
Yes
Step-by-step explanation:
xy=yx because either way, you would end with the same product. For example, if x was 3 and y was 2, you would have (3)(2)=(2)(3), giving you 6=6 which is, in fact, a true statement.
The lines represented by the equations y = 1x – 5 and 3y + x = -15 are
O
parallel
Submit Answer
the same line
neither parallel nor perpendicular
perpendicular
Answer:
Neither parallel nor perpendicular
Step-by-step explanation:
The lines represented by the equations y = 1x – 5 and 3y + x = -15 are .....
Solve for y in 3y + x = -15.
[tex]3y + x = -15 \\ \frac{ - x = - x}{3y = - x - 15} \\ \\ \frac{3y = - x - 15}{3 \: \: = \: \: \: \: \: \: \: \: \: 3} \\ y = - \frac{1}{3}x - 5[/tex]
[tex]y = - \frac{1}{3}x - 5 \: and \: y = 1x - 5[/tex]

Answer:
= 18 square units
Step-by-step explanation:
area = full square units + 1/2 x half-full square units
2
remember that if a square is not full it is NOT full: hence it will be considered as half full.
full square units =12
1/2 full square units =12
12 + 12/2
12 + 6
= 18 square units
Estimate a 15% tip on a dinner bill of $41.35 by first rounding the bill amount to the nearest ten dollars.
Answer:
Total you have to pay: $47.55
Tax amt: $6.20
Step-by-step explanation:
Multiply $41.35 by 1.15
How this works, when your increasing an amount you first change the percentage to a decimal number. Afterwards you add the decimal number
Ex: 1 + .15= 1.15
Or the opposite: 1 - .15= .85
Then multiply your original number by the number you got from the previous step.
Ex: $41.35 x 1.15=47.55
And to find how much you increase just do (Final amount-Initial Amount)
