Answer:
Figure B
Step-by-step explanation:
Step-by-step explanation:
Let the two numbers be X and Y respectively.
<u>We know that</u> :
(a) X = 6Y + 5
(b) X + Y = 75
7Y + 5 = 75
X = 65
Y = 10
Answer:
The photographer will take 80 pictures in 10 minutes
Step-by-step explanation:
if 64 pictures were taken in 8 minutes that's 8 pictures every minute, with that knowledge 8 pictures in 10 minutes would be 80 pictures.
Answer:
y = 
x + 
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 = - 2x - 4 ← is in slope- intercept form
with slope m = - 2
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
= , thus
y = x + c ← is the partial equation
To find c substitute (3, 4) into the partial equation
4 = 
+ c ⇒ c = 4 - =
y = x + ← equation of line
