Answer:
-1 1/2
Step-by-step explanation:
9/10 ÷ -3/5
Copy dot flip
9/10 * -5/3
-45/30
Divide the top and bottom by 15
-3/2
Change this to a mixed number
-1 1/2

1. Replace x with the given values and see if the equation equals the Y value:
y = -5x +4
-5(5)+4 - -25 +4 = -21
The answer is D.
2. -4 = g+1
Subtract 1 from each side:
-5 =g
The answer is C.
3. The 2nd chart is correct, ( the top one on the picture with 2) because when Tony is 5 the line is on Y = 0, when the line is on 6 it is on Y=1, which keeps Tony at 5 years older.
Well all you need to do to write the linear equation for this function. I assume you want to know, is that you must obtain 2 points, and calculate the slope, then place the info within the following form.
Y = mx + b
1 of the points has to be the y intercept, which can be obtained from the graph, and the other, any other point, which can also be the X intercept.
So, X intercept - (2,0)
Y intercept - (0,3).
Slope = y/X = 3-0/0-2
Slope = 3/-2 or -3/2.
Now put everything together in form:
Y = mx + b
Y = -3/2x + 3.
I believe this is the solution.
Answer:
x = 70
y = 110
z = 30
Step-by-step explanation:
all triangles add up to 180
30 + 80 = 110
180 - 110 = 70
x = 70
30 + 40 = 70
70 + 80 = 150
180 - 150 = 30
z = 30
40 + 30 = 70
180 - 70 = 110
y = 110
