Answer:
d
Step-by-step explanation:
Plug in 0 for y to find the x intercept:
7x +3(0)= -21
7x=-21
x= -3
Plug in 0 for x to find y intercept:
7(0) + 3y= -21
3y= -21
y= -7
Answer:
C
Step-by-step explanation:
<h3>7.4 x 10 <em>-3</em>= 0.0074</h3><h3>1.3 x 10 <em>-2</em>= 0.013</h3>
In between them would be 0.0092.
Answer:
145
Step-by-step explanation:
The discriminant of quadratic ...
ax^2 +bx +c = 0
is ...
d = b^2 -4ac
For your quadratic, you have a=4, b=-7, c=-6, so the discriminant is ...
d = (-7)^2 -4(4)(-6) = 49 +96 = 145
The discriminant is 145.
