Answer:

(−4, −8), because the point satisfies both equations

Step-by-step explanation:

Line A  

y = x - 4

Line B

y = 3x + 4

If we equate those 2 equations

x - 4 = 3x + 4

2x = -8

x = -4

y = -8

Answer:

C. (-4,-8), because the point satisfies both equations

Step-by-step explanation:

You need to graph both equations. For line A, the y-intercept is -4, so you plot a point on -4. The slope is one, so you rise up one and run right 1. For line B, the y-intercept is 4, so you plot a point on 4. The slope is 3, so you rise up 3 and run right 1. Then, you look for where the 2 lines intersect. In this case, line A and line B intersect at the point (-4,-8).

sveticcg [70]

The options aren't given, however, the range of amount spent could be calculated

Answer:

Kindly check explanation

Step-by-step explanation:

Paula purchase 3 dvd and 7 cds and spent between 90 and 100. Each dvd costs the same amount the price of cd is 10 select all amounts that could be the price of the dvd

Given that :

DVD costs the same amount

Number of DVD's = 3

Cost of cds = 10

Number of cds = 7

Total cost of cd's = 10 * 7 = 70

Let the price of DVD = x

Total amount spent = 90 - 100

Lowest price of DVD :

(amount spent - price of cd) / number of dvd

(90 - 70) / 3 = 20 /3 = 6.667

Highest price :

(100 - 70) / 3 = 30 / 3 = 10

Hence the pice of each DVD will range between /

6.6666 and 10.

Hence, prices listed within the range above are possible.

12(5 x-4.5)=36 what is the value of x
-Dominant- [34]

Answer:

x=

3 /2

Step-by-step explanation:

12(5x−4.5)=36

(12)(5x)+(12)(−4.5)=36(Distribute)

60x+−54=36

60x−54=36

Step 2: Add 54 to both sides.

60x−54+54=36+54

60x=90

Step 3: Divide both sides by 60.

60x

60

=

90 /60

x=

3 /2
