I think (jk) (x) means j times k

(jk) (x) = -7x(9 - 2x) //Using Distributive Property.

(jk) (x) = -63x + 14x^2 = 14x^2 - 63

//Hope it helps.

Enter the correct answer in the box. Add the two functions. f(x) = 3x3 + 7x − 26 g(x) = x + 2 Write your answer in the standard

kotykmax [81]

f(x) + g(x) = 3x³ + 8x - 24

that is 3x³ + 7x - 26 + x + 2 = 3x³ + 8x - 24

The little Mexican restaurant sells only two kinds of beef burritos mucho beef sandwich Lucho beef last week the restaurant orde

Finger [1]

Answer:

Cost of a single Mucho beef burrito: $\$5.5$

Cost of a double Mucho beef burrito: $\$6.5$

Step-by-step explanation:

<h3> The exercise is: "The Little Mexican restaurant sells only two kinds of beef burritos: Mucho beef and Mucho Mucho beef. Last week in the restaurant sold 16 orders of the single Mucho variety and 22 orders of the double Mucho. If the restaurant sold $231 Worth of beef burritos last week and the single neutral kind cost $1 Less than the double Mucho, how much did each type of burrito cost?"</h3>

Let be "x" the the cost in dollars of a single Mucho beef burrito and "y" the cost in dollars of a double Mucho burrito.

Set a system of equations:

$\left \{ {{16x+22y=231} \atop {x=y-1}} \right.$

To solve this system you can apply the Substitution Method:

1. Substitute the second equation into the first equation and solve for "y":

$16(y-1)+22y=231\\\\16y-16+22y=231\\\\38y=231+16\\\\y=\frac{247}{38}\\\\y=6.5$

2. Substitute the value of "y" into the second equation and evaluate in order to find the value of "x":

$x=6.5-1\\\\x=5.5$

What is the equation of the following line? (0,0) (6,2)

leva [86]

If you want it to be a slope intercept form, the first you have to find slope.

y2-y1/x2-x1

2-0/6-0

2/6 = 1/3

Then you need to find the y intercept. Plug in the x and y value in y=mx+b.

2=1/3(6)+b

2=2+b

0=b

ANSWER: y=1/3x+0

Hope this helps and is correct :)
