The answer is choice 4. You can do this to ways. One is factoring. To factor you do 2x^2-2x+3x-3. 2x(x-1)+3(x-1). (2x+3)(x-1). You could do that or multiply each answer choice out. Either way you get answer choice 4.

Find an equation, in slope-intercept form, that passes through point (-3, -7) with slope -3.
Thepotemich [5.8K]
Slope-intercept form is y = mx + b, and m is the slope
Because the slope is -3, m = -3
y = -3x + b

Plug in the point and solve for b
-7 = -3(-3) + b
-7 = 9 + b
-16 = b

a. y = -3x -16

1000 tickets were bought at a concert. the amount needed to buy a children’s ticket was $4.50 and the amount needed for an adult
Sholpan [36]

Answer:

The number of children's tickets bought was 300 and the number of adult tickets bought was 700

Step-by-step explanation:

Let

x ----> the number of children's tickets bought

y ----> the number of adult tickets bought

we know that

x+y=1,000

x=1,000-y -----> equation A

4.50x+8.50y=7,300 -----> equation B

Solve the system by substitution

substitute equation A in equation B

4.50(1,000-y)+8.50y=7,300

solve for x

4,500-4.50y+8.50y=7,300

4y=7,300-4,500

4y=2,800

y=700

<em>Find the value of x</em>

x=1,000-700=300

therefore

The number of children's tickets bought was 300 and the number of adult tickets bought was 700
