What’s the answer???

Answer:

[tex]b = ( - 8)[/tex]

Step-by-step explanation:

[tex] \frac{1}{4} b + 1 = \frac{1}{2} b + 3 \\ \frac{1b}{4} - \frac{1b}{2} = 3 - 1 \\ \frac{1b}{4} - \frac{1b \times 2}{2 \times 2} = 2 \\ \frac{1b}{4} - \frac{2b}{4} = 2 \\ \frac{1b - 2b}{4} = 2 \\ \frac{ - b}{4} = 2 \\ - b = 2 \times 4 \\ - b = 8 \\ b =( - 8)[/tex]

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.

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

Answer:

isnt it 132:89??

sorry I'm confused

Answer:

FIRST !!!!

anything raised to the zero power is equal to 1 (one)

so I think that three is wrong....

as for 4....

3/3 = 1    5/5= 1    x/x = 1 anything divided by itself is one...

so you have 1*1 = 1

as for 5 ... it is the same as for ALL THE STUFF on the TOP

gets cancelled by the SAME items on the BOTTOM ???/??? if they are the same the answer is 1

NOTE if ??? = zero then we have a problem .. you can't divide by zero that is an exception

Step-by-step explanation:

Answer:

When you have the same numerator and denominator in a fraction, it is always equal 1.

The answer is 1.

The Answer is -467

Step-by-step explanation:

all it did was move the decimal to the right once

So this way we can do it. Thankyou!

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.

Answer:

(- ∞ , 3) u (7 , ∞ )

Step-by-step explanation:

f(x) is negative below the x- axis

This is int the intervals x < 3 , x > 7

domain is (- ∞ , 3 ) u (7, ∞ )

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.

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.

perpendicular lines intersect in at least two points..

ok im not sure sorry

Step-by-step explanation:

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

= 4
