Answer:
The kitchen has a bigger actual area than the bedroom
Step-by-step explanation:
Here, we want to know the compartment with the bigger area
Since the bedroom has a drawing measure of 1 to 40; compared to the actual measurement;
The real dimensions will be;
10 * 40 and 18 * 40
= 400 by 720
So, its area which is length * width will be;
400 cm * 720 cm = 288,000 cm^2
we can see that the kitchen with an area of 300,000 cm^2 is bigger than this area of the bedroom
Answer:
y=-6x-14
Step-by-step explanation:
1. y=mx+b
2. y=-6x+b
3. plug in the point to y and x
4. -8=-6(-1)+b
5. -8= 6+b
6. -8-6=b
7. -14=b
8. Equation = y=-6x-14
Y – 3x = 7
y -3x +3x = 7+3x
y = 7+3x
21 + 9x = 3y
21 + 9x = 3(7+3x)
21 + 9x = 21 + 9x
The answer is B.There are an infinite number of solutions.
Answer:
$35.70
Step-by-step explanation:
15% of 42 = 6.3
42 - 6.3 = 35.7
x - 4y = 15
-x -x (subtract x on both sides)
-4y = 15 -x
---- -------- (divide by -4 on both sides)
-4 -4
y = -3.75 - 1/4x (change to slope-intercept form which will be y = -1/4x -3.75)
substitute that equation for y on the other equation so you will get
x - 4(-1/4x - 3.75) = 15
x + 1x + 15 = 15 (use distributive property)
2x + 15 = 15 (combine like terms)
2x = 0 (subtract 15 on both sides)
x = 0 (divide both sides by 2)
substitute for x on any equation (Im going to be using x - 4y = 15)
0 - 4y = 15
-4y = 15 (add 0 to both sides)
y = -3.75 (divide both sides by -4)
Point of intersection is (0, -3.75)
