Answer:
8/35
Step-by-step explanation:
5/7-2/5=25/35-17/35=25-17/35=8/35
Answer:
Step-by-step explanation:
You can tell by looking at the form of each equation.
y = tx
This is a straight line that passes through the origin, so it symmetric with respect to the origin.
y = x²+1
This is an up-opening parabola with vertex at (0,1), so it is symmetrical about the y-axis.
y = x²+x = (x+½)² - ¼
This is an up-opening parabola with vertex at (-½,-¼). Not symmetrical to either axis nor to the origin.
Can't tell what "y = (1 + x2)3" means. Which terms are exponents?
Answer:
Step-by-step explanation:
The slope-intercept of 4x-2y=3 is (-3/2) which is -1.5 in decimal form.
The slope-intercept of 3y+x=5 is (5/3) which is 1.666...
Answer:
15
Step-by-step explanation:
Opposite angles, angles that are opposite each other when two lines cross, are also known as vertical angles because the two angles share the same corner. Opposite angles are also congruent angles, meaning they are equal or have the same measurement.
Therefore 60 = x + 45 or 60 - 45 = x =15
Answer:
x=30°
Step-by-step explanation:
50 + x =80 degree (sum of two interior opposite angles is equal to the exterior angles formed)
x=80-50
x=30 degree
