Answer:
$250
Step-by-step explanation:
The numbers in the table indicate a proportional relationship between earnings and hours worked. Among other things, that means you can find the earnings for 20 hours by using any table values that sum to 20 hours.
For example, 9 hours + 11 hours = 20 hours, so the earnings would be ...
$112.50 +137.50 = $250.00 . . . for 20 hours
You could also use 4×5 hours = 20 hours, so ...
4×$62.50 = $250 . . . for 20 hours
__
Or, you can figure ...
$37.50/(3 h) = $12.50/h
so the pay for 20 hours is ...
(20 h)×($12.50/h) = $250.00
1. 9.5x + 1.5
2. 9x + 36
3. 4.8x + 2
4. 22x + 2
Answer:
(23,-4):
units
Step-by-step explanation:
We are given that M(-19,4)and P(4,0)
We have to find the ordered pair that represents MP and find the magnitude of MP.
MP=P-M
MP=(4,0)-(-19,4)=(4+19,0-4)
MP=(23,-4)
Magnitude of MP=
Magnitude of MP=
Magnitude of MP= units
Hence, .option c is true.
Answer:c.(23,-4): units
Answer:
A. 0
B. -66
C. 4
D. 998
E. -12
Step-by-step explanation:
A. By definition, the sum of anything and its additive inverse is zero.
__
B. If you have trouble with sums, your calculator can help.
-22 + (-44) = -22 -44 = -66
__
C. -36/x = -9 can be solved by multiplying by x and dividing by -9:
-36 = -9x
-36/-9 = x = 4
Since the product of the divisor and quotient is the dividend, dividing the dividend by either gives the other. Here, your dividend is -36 and your quotient is -9. To find the divisor, you can divide -36 by -9, as we did.
__
D. The absolute value function changes the sign of negative numbers to positive:
|-998| = 998
__
E. If you have trouble with sums, your calculator can help.
(−2)−[(−3)−(−7)−(−6)]
= -2 -(-3 +7 +6) = -2 -10 = -12
Answer:
see below
Step-by-step explanation:
1.
a)
the relation is
b)
we can use it because for every value of x there is just one value, as the definition of function states
c)
and
2.
the points are
(-2,2) with
(1,-3) with
so the change in y is 
and the change in x is 
so the slope is
and the general formula is
so with a=-5/3
we plug in point 1
so the formula is
expressed as a function is
3.
this is bassically all the work of number 2, so we have
(-2,-5)
(4,31)
so the slope will be
the change in y
the change in x
so the slope will be
(the triangle means change)
so the formula we have
we plug some point, let's say 1
so the formula is
as a function is
so there you have it
Just as a note, for the next one, put more points :)
