Answer:

1, 3, and 4 are true

Step-by-step explanation:

1. y=mx+b, m is the slope

2.  Parallel lines have the same slope. -2 is not equal to 2

3. y=mx+b, b is the y-intercept

4. Perpendicular lines,

If you multiply the slopes and the result is -1.

Answer:

A. Store A will cost about $1.28 less

Step-by-step explanation:

Store A:

Unit rate = y/x

Using any given pair, say (3, 7.26),

Unit rate = 7.26/3 = $2.42 per gallon

So, of a customer is buying 16 gallons at Store A, he'd pay:

$2.42 * 16 = $38.72

Store B:

Unit rate = y/x

Using any point on the graph, say (20, 50),

Unit rate = 50/20 = $2.5 per gallon

So, of a customer is buying 16 gallons at Store B, he'd pay:

$2.5 * 16 = $40.

Cost of Store B - Cost of Store A = $40 - $38.72 = 1.28

This means that Store A cost about $1.28 less

Answer:

that put into the advanced course is 396.75

Step-by-step explanation:

The computation of that put into the advanced course is shown below:

P(X>60)

= P((X - mean) ÷ s > (60 - 50) ÷ 10)

= P (Z > 1)

= 0.1587

It could be checked by the standard normal table

Now that put into the advance course is

= 2,500 × 0.1587

= 396.75

Hence, that put into the advanced course is 396.75

Answer:

2.50 dollars every 15 minutes

Step-by-step explanation:

Answer:

The options are not shown, so i will solve this in a general way.

Let's suppose that there are N nuts

If we divide the N nuts into groups of 5, there will be a remainder of 2 nuts.

If we divide the N nuts into groups of 3, there is no remainder.

This means taht N is a multiple of 3. then we can write:

N = 3*k

where k is a random integer.

Now, we know that when we divide N by 5, there is a remainder of 2 nuts, this means that N is equal to a multiple of 5 plus 2, then we can write:

N = 5*j + 2

where j is a random integer.

Now we only need to find a pair of k and j (both positive integers) such that:

3*k = 5*j + 2

We can rewrite this as:

k = (5/3)*j + (2/3)

Now we could just input different values of j, and see if k is also an integer:

j = 2

k = (5/3)*2 + 2/3 = 10/3 + 2/3 = 12/3 = 4

Then the pair j = 2, k = 4 is a possible solution.

N = 3*k = 3*4 = 12

N = 5*j + 2 = 5*2 + 2 = 12

From this we can conclude that N = 12, so Scrat has 12 nuts.

Now with the equation

k = (5/3)*j + (2/3)

We can find other possible combinations of j and k, that will give different values for N.

for example, if j = 5:

k = (5/3)*5 + 2/3 = 25/3 + 2/3 = 27/3 = 9

Then the pair j = 5, k = 9 is also a possible solution:

N = 3*k = 3*9 =  27

N = 5*j + 2 = 5*5 + 2 = 27

In this case, Scrat has 27 nuts.

We conclude that:

[tex]h\left(3k-12.4\right)=3hk-12.4h[/tex]

Step-by-step explanation:

Given the expression

[tex]h\left(3k-12.4\right)[/tex]

Expanding the expression

Let us expand the expression

[tex]h\left(3k-12.4\right)[/tex]

Apply the distributive law: a (b - c) = ab - ac

here a = h, b = 3k, c = 12.4

so th expression becomes

[tex]h\left(3k-12.4\right)=h\cdot \:\:3k-h\cdot \:\:12.4[/tex]

                     [tex]=3hk-12.4h[/tex]

Therefore, we conclude that:

[tex]h\left(3k-12.4\right)=3hk-12.4h[/tex]

Answer:

y= -1

Step-by-step explanation:

subtract, so x cancels out.

you are left with 2y=-2

y= -1

Answer:

y = - 1

Step-by-step explanation:

x + y = 1 .......... (1)

x - y = 3 .......... (2)

(1) + (2)

2x = 4 ⇒ x = 2

2 + y = 1 ⇒ y = - 1

(2, - 1)

Step-by-step explanation:

Answer:

Step-by-step explanation:

2(3x+1)-3(x+2)

or,6x+2-3x+6=2

or,6x-3x=6-2+2

or,3x=6

or,x=2

Step-by-step explanation:

We can find x very easily because the left and right sides are parallel,making the diagonal connecting them a transversal therefore x=33°

To find y we know that the sum of interior angles of a triangle is 180°

y+109°+33°=180°

y+142°=180°

y=38°

Now,

x+38°+z=180

33+38+z=180

z=180-71=109°

Answer:

W is less than or equal to 2200

Step-by-step explanation:

(I don't know how to do the less than or equal to symbol on the computer)

The inequality equation is w ≤ 2200 , where w is the maximum amount of weight in an elevator

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Let the maximum weight in an elevator be w

Now , the maximum weight an elevator can lift is given by = 2,200 pounds

So , the inequality relation is given by

w ≤ 2,200 pounds   be equation (1)

Therefore , the value of A is w ≤ 2,200

Hence , the inequality relation is w ≤ 2,200
