Answer:

Step-by-step explanation:
Rachel's cost = $35x + $15
Taylor's cost = $25x + $75
When are the costs equal? Rachel's cost = Taylor's cost?
35x + 15 = 25x + 75
35x - 25x = 75 - 15
10x = 60
x = 6
Check Rachel's 6 month cost is: 35 x 6 + 15 = 225
Check Taylor's 6 month cost is 25 x 6 + 75 = 225

Answers
Answer:
B for me
Step-by-step explanation:
Yun lang po correct me if iam wrong
The Required equation for the ellipse is given by [tex]\frac{(x-4)^2}{49}+\frac{y+1}{100} = 1[/tex] Option B. is correct
What is an ellipse?Ellipse is cross-section part of a cone structure when cutting it out a horizontal cross-section of a cone.
(x-h)^2/a^2 + (x-k)^2/b^2 = 1
(h,k) = centre of the ellipse.
a, b = semi minor or major axis,
[tex]\frac{(x-4)^2}{49}+\frac{y+1}{100} = 1[/tex]
thus, the required equation of ellipse is given by [tex]\frac{(x-4)^2}{49}+\frac{y+1}{100} = 1[/tex].

Answer:
D. 40.0km
Step-by-step explanation:
When rounding to 3 significant figures, we will have to look at the 4th significant figure. If that figure is 1-4, you round the 3rd figure down. If that figure is 5-9, you round the 3rd figure up.
In this case, the 3rd figure is the tenth 9 and the 4th figure is the hundredth 7.
Since 7 is from 5-9, you round the tenth 9 up. This adds one whole to 39, which makes it 40. You also need to keep 3 significant figures so the decimal zeros are significant. Thus, the answer is 40.0km

The following rectangle has an area of 3x^2-5x-12. What are the possible side lengths, in terms of x? Explain your answer and justify how you know that the sides you found are possible lengths
Answers
Answer:
the possible side lengths:
3x+4 and x-3
Step-by-step explanation:
factorize the the expression and you will get two expressions in terms of x. those expressions are the lengths of the rectangle
[tex]3 {x}^{2} - 5x - 12[/tex]
1) write -5x as a difference
[tex]3 {x}^{2} + 4x - 9x - 12[/tex]
2) factor out x from the expression 3x²+4x
[tex]x(3x + 4) - 9x - 12[/tex]
3) factor out -3 from the expression -9x-12
[tex]x(3x + 4) - 3(3x + 4)[/tex]
4) factor out 3x+4 from the expression
[tex](3x + 4)( x - 3)[/tex]
the possible lengths are 3x+4 and x-3
to check whether the answer is correct, you can just multiply the both lengths using the area of rectangle formulae
area of rectangle formulae
[tex]length \times height[/tex]
(3x+4)(x-3)
= 3x²-9x+4x-12
= 3x²-5x-12 ( proven )
Simplify: (5x2 - 9x + 3) + (4x2 + 4x - 12)
(1) 9x2 + 5x - 9
2) 9x2 - 5x + 15
3) 9x² - 5x-9
4) 9x2 - 13x - 9
Answers
Answer:
3) 9x² - 5x - 9
Step-by-step explanation:
Combine like terms
5x² - 9x + 3 + 4x² + 4x - 12 = 5x² + 4x² - 9x + 4x + 3 - 12
= 9x² - 5x - 9

For an absolute value function, the graph will look like an arrow with a sharp inflection point.
Reciprocal function will tend towards a limit when stretched to infinity.
Cube root and square root functions do not tend towards infinity at x = 0, because it is either 0 or the constant value.

if an object has a density of 3.6g/ml and you put it into water, will it sink or float?
Answers
Answer:
Sink
Step-by-step explanation:
We need to find if an object with a certain density will float or sink in water.
The object will sink in water.
The density of the object is 3.6 g/mL
The density of water is generally [tex]1000\ \text{kg/m}^3[/tex]
An object which has a density more than the liquid it is in then the object will sink.
Let us convert the density of the object to [tex]\text{kg/m}^3[/tex]
[tex]1\ \text{g}=10^{-3}\ \text{kg}[/tex]
[tex]1\ \text{mL}=10^{-6}\ \text{m}^3[/tex]
[tex]1\ \text{g/mL}=\dfrac{10^{-3}}{10^{-6}}=10^3\ \text{kg/m}^3[/tex]
[tex]3.6\ \text{g/mL}=3.6\times 10^3=3600\ \text{kg/m}^3[/tex]
The density of the object [tex](3600\ \text{kg/m}^3)[/tex] is greater than that of water [tex](1000\ \text{kg/m}^3)[/tex].
Hence, the object will sink.

On Saturday, a souvenir shop had 125 customers. Sixty-four percent of the customers paid with a credit card. The other customers paid with cash. How many customers paid with cash?
Answers
Answer:
45 customers
Step-by-step explanation:
Given
Total number of customers = 125
percent that paid with credit card = 64%
Customers that paid with credit card = 64% * 125
Customers that paid with credit card = 0.64 * 125 = 80
Number of customers that paid with cash = 125 - 80
Number of customers that paid with cash = 45 customers
P(x) = 2x3 – x2 + 4x + 5 is divided by x + 2. Choose the correct option from each drop-down menu.
When P(x) is divided by x + 2, the remainder is [ ] P(–2) = [ ]. The Remainder Theorem is [verfied/not verified] ]
Answers
The remainder of the division of polynomial, P(x) = 2x3 – x2 + 4x + 5 by (x + 2) is; -23
The remainder of the division of the polynomial, P(x) = 2x3 – x2 + 4x + 5 by (x + 2) can be evaluated by the remainder theorem.
This involves adding evaluating the value of the polynomial at, x = -2.
Since, (x +2) is the Divisor, we evaluate, P(x) at x = -2Therefore, we have;
P(-2) = 2 ×(-2)³ -(-2)² + 4(-2) + 5P(-2) = -16 -4 -8 +5P(-2) = -23.Therefore, the remainder when P(x) = 2x3 – x2 + 4x + 5 is divided by (x + 2) is; -23
