Mathematics
1 answer:
jekas [21]4 years ago
7 0

Answer:

First Equation answer: r > 2

Second Equation answer: 7 (r+3)

Step-by-step explanation:

First Equation Explanation: Move variable to the left side (2r + 2r + 8 > 16)

See the like terms (4r > 16-8)

Divide both sides by inequality of 4 (4r > 8) 4r----> r > 2

Second Equation Explanation: Factor out 7.

A cashier earns $7 an hour. If x is the number of hours worked, which function represents the cashier’s earnings? y = 7x y = x 7
Vilka [71]
I think its 7x since x represents the hours she worked. So lets say that she worked for 5 hours this day. It would be 5*7 which is $35. So it is 7x and if there is any choices you might say it as well so we can help you better

Part A: the radicand is the same as the discriminant, therefore is b2 - 4ac
In 9x^2 - 16x + 60 = 0, a = 9, b = -16, c = 60
so b2 - 4ac =
{b}^{2}  - 4ac =  {( - 16)}^{2}  - 4(9)(60) \\  = 256 - 2160 = 1904 \\  \sqrt{1904}  =  + 43.63 \: and \:  - 43.63

Part B: Solve 4x^2 + 8x - 5 = 0
What would make 8? (5×2)-2 = 8, so:
(2x+5)(2x-1) = 0
2x+5 = 0
2x = -5
x = -5/2
2x-1 = 0
2x = 1
x = +1/2
So the solutions are: -5/2, +1/2

Which of the following could be a function with zeros of —3 and 2? А f(x) = (x - 3)(x + 2) B f(x) = (x = 3)(x - 2) © f(x) = (x+3
Zinaida [17]

Answer:

C

Step-by-step explanation:

to find the zeros you look at what value you would fill in for x to make zero, so (x+3) would have a zero of -3 and (x-2) would have a zero of 2

Hannah was adding 5 plus -4. When explaining her work she said that the sum is 9 because you add the numbers and take the sign o
Scilla [17]

Answer:

The sum is 1

Step-by-step explanation:

When you add a negative number to a positive number, it is basically just subtracting the negative from the positive. To make it simple, 5 + -4 is just 5 - 4.

Hannah was wrong in saying you take the sign of the larger number because it would not matter if the first number was a million, the signs don't change based on the size of numbers.
