Answer:

(-2,21)

Step-by-step explanation:

2 days ago, Paulo's commute time was halfway between his commute times 8 and 9 days ago.

8 days ago means that x-coordinate -8 represents this day. Count 8 units to the left and find that when x = -8, y = 24 minutes.

9 days ago means that x-coordinate -9 represents this day. Count 9 units to the left and find that when x = -9, y = 18 minutes.

Find halfway commute time between points (-8,24) and (-9,18):

$y=\dfrac{24+18}{2}=\dfrac{42}{2}=21,$

then coordinates that Paulo should graph are

(-2, 21)

(-2 means 2 days ago, 21 is the halfway)

A square cake is cut into 16 equal parts.

So 4 times 4 is 16 so the 1/4 is now 4/16 plus the 7/16 equals 11/16 so the left number is 5/16

Urgent help!

Answer:

4x³ − 15x² − 10x + 24

Distribute

x · 4x² + x · x + x · -6 + (-4) · 4x² + (-4) · x + (-4)(-6)

Simplify:

4x²x + xx - 6x - 4 · 4x² - 4x + 4 · 6

Further simplify (by adding and subtracting like terms)

4x³ − 15x² − 10x + 24

Hope this helps :)

Solve each given equation and show your work. Tell weather each equation has one solution, an infinite number of solutions, or n

galben [10]

Hello!

To solve algebraic equations, you need to SADMEP it. SADMEP is only used to solve these equations, and it is an acronym for subtraction, addition, division, multiplication, exponents, and parentheses. The goal here is to get x on one side of the equation.

(a) 4x + 2(x - 1) = 10 + 2x (use the distributive property)

4x + 2x - 2 = 10 + 2x (add alike terms)

6x - 2 = 10 + 2x (subtract 2x from both sides)

4x - 2 = 10 (add 2 to both sides)

4x = 12 (divide both sides by 4)

x = 3

This equation has one solution because if you substitute 3 for x into the original equation, then both sides of the equation will be equal.

(b) 30 - x = 10 + -1(6x + 10) (use the distributive property)

30 - x = 10 + -6x - 10 (simplify)

30 - x = -6x (add x to both sides)

30 = -5x (divide both sides by -5)

x = -6

This equation has one solution because if you substitute x = -6 into the given equation, then the left and right side of the equation will be equivalent to each other.

8x = 8x + 10(0) (multiply)

8x = 8x

This equation has an infinite number of solutions because if you substitute any number into the given equation, both sides of the equation will be equal.

Does anybody know this ?

Aleonysh [2.5K]

Answer:

0, 1, 2, 3, 4

Step-by-step explanation:

Multiply each x value by 1/3 then add 2. Since the numerator is 1, you would multipy by one and divide by the denominator of 3, so you really need to divide each x value by 3 then add 2.

-6:

-6/3 = -2

-2 + 2 = 0

-3:

-3/3 = -1

-1 + 2 = 1

0/3 = 0

0 + 2 = 2

3/3 = 1

1 +2 = 3

6/3 = 2

2 + 2 =4

which set of side lengths form a right side?a) 3ft,6ft,5ft b)50 in,48in,14in c)53m,48m,24m d)8cm,17cm,14cm

muminat

Answer:

Step-by-step explanation:

If a ≤ b < c form of a right side, then a² + b² = c²

a) 3ft, 6ft, 5ft

3² + 5² = 6²

9 + 25 = 36

34 = 36 FALSE

b) 50in, 48in, 14in

14² + 48² = 50²

196 + 2304 = 2500

2500 = 2500 CORRECT :)

c) 53m, 48m, 24m

24² + 48² = 53²

576 + 2304 = 2809

2880 = 2809 FALSE

d) 8cm, 17cm, 14cm

8² + 14² = 17²

64 + 196 = 289

260 = 289 FALSE
