Hello,
Adding the 2 equations,
x+y+x-y=k+k ==>2x=2k==>x=k
if x=k, y=k-k=0
solution is (k,0)

Answer:

(k,0)

Step-by-step explanation:

x+y=k

x-y=k

To solve for x  and y we add both equations

x+y=k

x-y=k

---------------------------

2x=2k

Divide both sides by 2

x=k

Now plug in k for x and find out y

x+y=k

k+y=k

Subtract k on both sides

y=0

Ordered pair is (x,y) that is (k,0)

The equation of a quadratic is =2^2+3−2and after you factorizing 2^2+3−2=0you got x = -2 and x = 1/2 and the curve crosses the y
Lelechka [254]

Given the next quadratic function:

y=2x^2+3x-2

to sketch its graph, first, we need to find its vertex. The x-coordinate of the vertex is found as follows:

x_V=\frac{-b}{2a}

where <em>a</em> and <em>b</em> are the first two coefficients of the quadratic function. Substituting with a = 2 and b = 3, we get:

\begin{gathered} x_V=\frac{-3}{2\cdot2} \\ x_V=-\frac{3}{4}=-0.75 \end{gathered}

The y-coordinate of the vertex is found by substituting the x-coordinate in the quadratic function, as follows:

\begin{gathered} y_V=2x^2_V+3x_V-2 \\ y_V=2\cdot(-\frac{3}{4})^2+3\cdot(-\frac{3}{4})-2 \\ y_V=2\cdot\frac{9}{16}+3\cdot(-\frac{3}{4})-2 \\ y_V=\frac{9}{8}-\frac{9}{4}-2 \\ y_V=-\frac{25}{8}=-3.125 \end{gathered}

The factorization indicates that the curve crosses the x-axis at the points (-2, 0) and (1/2, 0). We also know that the curve crosses the y-axis at (0,-2). Connecting these points and the vertex (-0.75, -3.125) with a U-shaped curve, we get:

Multiply: (9x − 5)(2x2 + 12x − 3)
Shtirlitz [24]

Answer:

A) is your answer

Step-by-step explanation:

Multiply the 2x by 9x

then you take the second variable in the second equation and mulitply it by 9x. giving you 98 x squared

THEN you take 9x times Negative 3 and get -87

AND NEGATIVE 5 TIMES NEGATIVE 3 IS

Raul has $460 in his checking account. Each month, $45 is automatically deducted from his account to pay for his cell phone plan
MissTica
X=number of months
how much is deducted total=number of months times amount deducted per m onth
amount deducted per month=45
number of months=x
how much deducted total=45x

460-deducted total is more than 100
460-45x>100
solve for x
add 45x to both sides
460>100+45x
subtract 100
360>45x
divide both sides by 45
8>x
answer is 7 months
if he does 8 months, then he will have exatly 100 and 100 is noe more than 100



answer is 7 months
