Answer:
Step-by-step explanation:
She needs to practice piano for 2 hours this week:
Lets add the time she played the piano so far:
Monday + Tuesday + Wednesday
Which is
20 + 30 (half an hour) + 15
= 65 minutes
In which 2 hours is equal to 120 minutes
So,
120 - 65 = 55
She needs to practice for 55 more minutes in this week
1) |x| is the absolute value function. Its vertex is at (0,0).
2) |x-1| has the same graph as does y = |x|, except that the vertex is shifted 1 unit to the left.
3) -3|x-1| has the same graph as the previous result, except that we must reflect the previous graph in the x-axis.
4) Replace the solid lines you used in this graph with dashed ones.
5) Shade the area beneath y = -3|x-1|
In summary:
the desired graph is the shaded area below the inverted v-shaped graph of
y = -3|x-1|. Its vertex is at (-1,0).
Answer:
3 time one third (1/3) equals 1
Answer:
y=-1/4x-1/2
Step-by-step explanation:
When two lines are parallel, they have the same slope.
So for this line, we already know that the slope (m) has to equal -1/4x.
Slope intercept form is y=mx+b, where m is the slope and b is the y intercept.
in order to find the equation, we must plug in x and y to solve for b, the y intercept (the value of y when x=0).
Now, let's plug in 2 for x and -1 for y and solve for b:
-1=-1/4(2)+b=-1=-1/2+b=-1+1/2=b
b=-1/2
Hence, the answer is y=-1/4x-1/2
PQRS is an isosceles trapezoid and m < Q=127
so m<Q = m<P =127
answer
127
