Y = (x +7)^2. The parabola is going into the negative region. The x value must be positive.
Answer:
y = - 3x - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 3x + 6 ← is in slope- intercept form
with slope m = - 3
Parallel lines have equal slopes.
The line crosses the y- axis at (0, - 4 ) ⇒ c = - 4, thus
y = - 3x - 4 ← equation of parallel line
To give every angle a label:
First angle = 2x
Second angle = x
Third angle = x + 68
So, because the sum of the interior angles of the triangle is 180°, we can say that: 2x + x + (x + 68) = 180
2x + x + x = 4x
4x + 68 = 180
Isolating for x we get: x = (180-68)/4 x = 28
Because the first angle is twice as large and the third angle is greater than the second angle, the measure of the smallest angle is 28°.
Answer:
B
Step-by-step explanation:
Since p and v vary inversely then the equation relating them is
p = 
← k is the constant of variation
to find k use the condition p = 8 when v = 40
k = pv = 8 × 40 = 320
⇒ p(v) = 
→ B
