Answer:
point G
Step-by-step explanation:
There's 14 marks between point A and B(counting point B). 14/2=7, the 7th mark is point G.
Answer:
Step-by-step explanation:
first graph
<h2>height=constant* width ( direct variation describes a linear relation between 2 variable )</h2>
6=8x ⇒ x=6/8=0.75
h=0.75w
<h2>constant is 0.75</h2>
second graph:
<h2>height=constant/width ( inverse variation)</h2>
15=x/4 ⇒x=4*15 ⇒x=60
<h2>constant=60</h2>
For two quantities with inverse variation, as one quantity increases, the other quantity decreases. k(constant)=xy
Answer:
2x - y = - 5
Step-by-step explanation:
First obtain the equation in slope- intercept form
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2, thus
y = 2x + c ← is the partial equation
To find c substitute (1, 7) into the partial equation
7 = 2 + c ⇒ c = 7 - 2 = 5
y = 2x + 5 ← in slope- intercept form
The equation in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Subtract y from both sides
0 = 2x - y + 5 ( subtract 5 from both sides )
- 5 = 2x - y, that is
2x - y = - 5 ← in standard form
Answer:
w + 1.3 = 2.7
Step-by-step explanation:
the 2 boxes above equal the bottom
Because of this we can write the equation w + 1.3 = 2.7
Answer:
Step-by-step explanation:
Distribute 4(x+2).
Subtract 2x and 8 from both sides.
Divide both sides of the equation by 2.
