Answer:
4m3−14m2+7m+4
Step-by-step explanation:
so you do 5m3+7m−7m2+4−7m2−m3
=5m3+7m+−7m2+4+−7m2+−m3
Combine Like Terms:
=5m3+7m+−7m2+4+−7m2+−m3
=(5m3+−m3)+(−7m2+−7m2)+(7m)+(4)
=4m3+−14m2+7m+4
Hope this helps
Answer:
y = -
+ 8
Step-by-step explanation:
So the y-intercept is already given; (0, 8)
So lets calculate the slope; 
The slope is -
Let's put it in slope-intercept form;
y = - + 8
Answer:
Angle 1 and angle 4 are congruent because all vertical angles are congruent. Angle 1 and angle 5 are congruent because corresponding angles are congruent. Idk the rest.
Step-by-step explanation:
The question is incomplete, the complete question is;
If in 0.5 min the tank gets 0.8 gallons of the water then
how many gallons will be in 1 min ?
how many gallons will be in 3 min?
and how long it takes for 40 gallons?
Answer:
1.6 gallons
4.8 gallons
25 mins
Step-by-step explanation:
This question has to do with proportion.
If it takes 0.5 mins for the tank to get 0.8 gallons
in 1 minute the tank will get 0.8 * 1/0.5 = 1.6 gallons
In 3 minutes the tank will get 3 * 1.6 gallons = 4.8 gallons
if it takes 1 min to get 1.6 gallons
it will take x mins to get 40 gallons
x = 1 * 40/1.6 = 25 mins
Answer:
Step-by-step explanation:
( Being vertically opposite angles)
Vertically opposite angles are always equal.
Move variable to L.H.S and change it's sign
Similarly, Move constant to R.H.S and change it's sign
⇒
Collect like terms
⇒
Subtract 18 from 50
⇒
Divide both sides of the equation by 2
⇒
Calculate
⇒
The value of x is 16
Now, let's find value of m<AFD :
( sum of angle in straight line )
plug the value of x
⇒
Multiply the numbers
⇒
Add the numbers
⇒
Move constant to R.H.S and change it's sign
⇒
Subtract 98 from 180
⇒
Value of m<AFD = 82
Hope I helped!
Best regards!!
