Answer:
2) (i) 224 (ii) -524
3 a and b are correct
Answer:
2) Subtract: (i) -244 (ii) -96
3) Verify the following: (a) 48 = 48, TRUE (b) 230 = 230, TRUE
Step-by-step explanation:
2) Subtract:
(i) 119 from -125
= -125 - 119
= -244
(ii) -214 from -310
= -310 - (-214)
= -310 + 214
= -96
3) Verify the following:
a. 16 [7 + (-4)] = [16 × 7] + [16 × (-4)]
= 16 [7 -4] = [112] + [16 × -4]
= 16 [3] = [112] + [-64]
= 48 = 112 - 64
= 48 = 48
This is true because both sides are equal.
b. -23 × [(-8) + (-2)] = [(-23) × (-8)] + [(-23) × (-2)]
= -23 × [-8 - 2] = [-23 × -8] + [-23 × -2]
= -23 × [-10] = [184] + [46]
= -23 × -10 = 184 + 46
= 230 = 230
This is true because both sides are equal.

Find WV 2X+26 2X+31
I'm not sure how to finish this problem or if I'm doing it right. Please help
Answer:
4
Step-by-step explanation:
Yes u are doing it right
So just find x first
2x + 26 + 2x +31 =13
4x + 57 = 13
4x = - 44
x = - 11
Since now u know x = - 11, and u know
WV =2X+26
So...
2x + 26
=2(-11) + 26
= - 22 + 26

Name a 3 digit number divisible by 4,5,9
9514 1404 393
Answer:
180
Step-by-step explanation:
The smallest such number is 4·5·9 = 180. Any multiple of 180 will be divisible by 4, 5, and 9.
The scatterplot shows the number of minutes Tyler played in his last eight basketball games and the points he
scored in each game. Estimate the location of the line of best fit. About howmany points would Tyler score if he
played for 40 minutes?
The equation of the line is : Ŷ = -0.1667+0.5935X.
The estimated number of points that will be obtained if Tyler played for 40 minutes is 24 points
To obtain the location of the line of best fit, we wrote out the coordinates of the points on the graph :
(6, 10) ; (8, 18) ; (10, 17) ; (12, 20) ; (17, 21) ; (11, 23) ; (14, 25) ; (18, 30)
Using technology, we can estimate the line of best fit :
Using a linear regression solver :
Y :
6, 8, 10, 12, 17, 11, 14, 18
X:
10, 18, 17, 20, 21, 23, 25, 30
The equation of the regression line obtained is :
Ŷ = -0.1667+0.5935X
The Number of points of Tyler played for 40 minutes :
x = 40
Ŷ = -0.1667+0.5935(40)
Ŷ = 23.5733 = 24(nearest whole number).
The estimated number of points that will be obtained if Tyler played for 40 minutes is 24 points.

Your cellular telephone provider offers two plans. Plan A has a monthly fee
of $15 and $0.25 per text. Plan B has a monthly fee of $20 and $0.05 per text.
Write and solve an equation to find the number of texts than you must send to
have the same cost for each of the plans.
Answer:
you must send 25 msgs to have the same cost
Step-by-step explanation:
x = n of messages
15+ (0.25x ) = 20 + (0.05x)
0.2x = 5
x = 25
Answer:
at 25 text the plan costs are equal
Step-by-step explanation:
Plan A = $15 + .25t
Plan B = $20 + .05t
when the plan costs are equal $A = $B
then
15 + .25t = 20 + .05t
.25t - .05t = 20 - 15
.2t = 5
t = 25

The equation y = 0.5x represents the distance Henry hikes in miles
per hour. The graph represents the rate that Clark hikes. Determine
which hiker is faster. Explain
Answer:
Clark is faster because the slope of his graph is bigger.
Step-by-step explanation:
The slope of Henry’s graph can be found as 0.5 because the equation is in slope intercept. (The coefficient of the x value is the slope)
Since there is a point at (12,18) in Clark’s graph, you can conclude Clark’s slope as 18/12. (Rise over run)
18/12 = 1.5
1.5 is bigger than 0.5 so Clark travels faster.
Closure illustrates that a characteristic of a set is not
necessarily a characteristic of all of its subsets. The real
numbers are closed with respect to multiplication, but the irrational numbers, a subset of the real numbers, are not. Give an example of a set that is not mathematical that has a particular characteristic, but which has a subset without this characteristic.
There are many examples to pick from, but one example is this:
The set of rational numbers (aka any fraction of two integers) is closed under the operation of division. Divide any two rational numbers and we get some other rational number.
However, the set of integers is not closed under division. If we divided 10 over 3, then we get 10/3 = 3.333 approximately which isn't an integer. So just because the set of integers is a subset of the rationals, it doesn't mean that the idea of closure follows suit from superset to subset.
Side note: The term "superset" is basically the reverse of a subset. If A is a subset of B, then B is a superset of A.
