Leo had a $30 gift card to use at a coffee shop. He used the entire balance to buy regular-sized coffees, which cost $2, and large coffees, which cost $3. If he bought 13 coffees in total, how many large coffees did he buy?
Select all that apply.
A. 2x+3y=30
B. 2x+3y=13
C. x+y=13
D. x+y = 30
Answer:
B
Step-by-step explanation:
Answer 4
If he bought 4 large coffees that means he spent $12 on them. that leaves $18. Which means he can buy 9 regular sized coffees. All together thats 13 coffees.

Use the graph of the polynomial
function to find the factored form of
its related polynomial. Assume it
has no constant factor
Answer:
The factored form of the polynomial is [tex]y = (x-2)\cdot (x+1)[/tex].
Step-by-step explanation:
According to the graph, we have a second order polynomial with a vertical axis of symmetry. The standard form of the polynomial is:
[tex]y = a\cdot x^{2}+b\cdot x + c[/tex] (1)
Where:
[tex]x[/tex] - Independent variable.
[tex]y[/tex] - Dependent variable.
[tex]a[/tex], [tex]b[/tex], [tex]c[/tex] - Coefficients.
We can obtain the solution of the polynomial by knowing three distinct points. From graph we know that the curve pass through the following three points: [tex](x_{1},y_{1}) = (-1, 0)[/tex], [tex](x_{2},y_{2}) = (0, -2)[/tex], [tex](x_{3},y_{3}) = (2,0)[/tex]. Three linear equations are constructed:
[tex]a^{2}-b+c = 0[/tex] (2)
[tex]c = -2[/tex] (3)
[tex]4\cdot a + 2\cdot b + c = 0[/tex] (4)
The solution of this system is [tex]a = 1[/tex], [tex]b = -1[/tex] and [tex]c = -2[/tex]. Then, the polynomial in standard form is [tex]y = x^{2}-x-2[/tex]. By factorization, we find that factored form is:
[tex]y = (x-2)\cdot (x+1)[/tex] (5)
SOMEONE PLEASE HELP! ITS ALMOST DUE!
Answer and Step-by-step explanation:
For this triangle, to find x, we will use the cosine trigonometric function.
cosine functions look like this:
[tex]cos(\theta) = \frac{adjacent}{hypotenuse}[/tex]
(The weird looking symbol is called theta, and represents an angle measurement)
Plug in the values into the equation.
cos(42) = [tex]\frac{x}{15}[/tex]
Multiply both sides by 15.
15(cos(42)) = x
Plug into a calculator.

Answer:
7x² - 26x + 9
Step-by-step explanation:
(g(x)²) = (3x - 2) (3x - 2)
(g(x)²) = 9x² - 6x - 6x + 4
(g(x)²) = 9x² - 12x + 4
(9x² - 12x + 4) - (2x² + 14x - 5) = 7x² - 26x + 9

Answer: All Real Number
Step-by-step explanation:
This is a system of equation, and generally, there are three ways to solve:
eliminationsubstitutionaugmented matrixHere, we are going to use elimination
------------------------------------------------------------------------------------
Given
-2x-y=1
-6x=3y+3
Put them in the same order
-2x-y=1
-6x-3y=3
Multiply 3 on both sides for the first equation
-6x-3y=3
-6x-3y=3
We subtract the first equation from the second equation
0=0
The answer will be All Real Numbers, which means any real number will fit this equation. In the graphing method, these two equations will overlap each other.
Hope this helps!! :)

Samuel is going to invest $4,900 and leave it in an account for 14 years. Assuming the
interest is compounded monthly, what interest rate, to the nearest tenth of a percent,
would be required in order for Samuel to end up with $10,300?
-
Answer:
Submit Answer
Answer:
0.053
Step-by-step explanation:
Using the compound formula A=P(1+r/n)^nt we can plug in the numbers we know. A being the total, P the initial amount, n is the number of compounds in a year, and t is the number of years passing. So 10300= 4900(1+ r/12)^12(14). We have to isolate r in order to find the rate. We can divide both sides by 4900, giving us 103/49= (1+ r/12)^168. Then we take the 168 square root from both sides. 1.00443… = 1 + r/12. Subtract 1 from both sides. 0.00443… = r/12. Then multiply both sides by twelve . r= 0.053
Solve For X. Solve similar triangles (advanced)
The value of x in the given similar triangles ADB and BCE is 4.5.
To solve for x in the given similar triangles ADB and BCE, we can set up the proportion of corresponding sides:
In triangle ADB, we have:
AB/BD = x/DE
Substitute the given values:
3/4 = x/6
Now, cross-multiply and solve for x:
3 * 6 = 4x
18 = 4x
x = 18/4
x = 4.5
So, the value of x is 4.5.
