Answer:

8x + 4y

here's your solution

=> (10x + 3y) - (2x - 4y)

=>. now multiple - to (2x - 4y)

=> hence we get -2x + 4y

=> now put this in above

=> 10x +3y -2x + 4y

=> solve for common terms

=> 8x + 7y

hope it helps

sarah spent a total of 10 on oranges and apples at the supet market. if she spent 3 dollars less for oranges than she did on app

beks73 [17]

Let's write 2 equations from the two statements given.

Sarah spent 10 dollars on both oranges and apples

Let the price of oranges be "x" and price of apples be "y", thus we can write:

$x+y=10$

Oranges cost 3 less than apples, thus we can say:

$y-3=x$

We can substitute this into the first equation and solve for y:

$\begin{gathered} x+y=10 \\ y-3+y=10 \\ 2y=10+3 \\ 2y=13 \\ y=\frac{13}{2} \\ y=6.5 \end{gathered}$

Thus, let's solve for x now,

$\begin{gathered} x=y-3 \\ x=6.5-3 \\ x=3.5 \end{gathered}$

We want the price of oranges (x), thus,

Price of Oranges = $3.50

Consider the parent quadratic function f(x) = x2.

zloy xaker [14]

F(x)=x+c, where c is an arbitrary constant.
if c is positive then translation above
if c is negative then translation down
reflection of f(x)=x^2 across x-axis then
f(x)=-x^2

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = 4x - 18

y = -5x + 9

Step 2: Solve for x

Substitution

Substitute in y [2nd Equation]: 4x - 18 = -5x + 9
[Addition Property of Equality] Add 5x on both sides: 9x - 18 = 9
[Addition Property of Equality] Add 18 on both sides: 9x = 27
[Division Property of Equality] Divide 9 on both sides: x = 3

Step 3: Solve for y

Substitute in x [1st Equation]: y = 4(3) - 18
Multiply: y = 12 - 18
Subtract: y = -6
