Question 2: x<-2

Question 6: 1.75 + 0.65m ≤ 10

Question 3: x ≥ -40

Question 4: Graph B

Step-by-step explanation:

Question 2:

since it needs to be greater than 11, we should add a number greater than 4 to seven. so it would be x>2. but since we are subtracting, we turn the 2 negative and flip the sign. Now it would be x<-2

Question 6:

the flat fee is 1.75 and they pay an additional 0.65 for every mile.

We know that the price has to be either less than or equal to 10. And the symbol is ≤. The inequality is 1.75 + 0.65m ≤ 10

Question 3 :

subtract 3 from both sides:

x/4 + 3 - 3 ≥-7 - 3

x/4≥-10

multiply each side by 4

x/4 * 4 ≥ -10 * 4

x ≥ -40

Question 4:

-3x-5 < -2

add 5 to both sides

-3x -5 + 5 < -2 + 5

-3x < 3

divide by -3

-3x / 3 < 3/3

x>-1

Answer:

y = -2x + 5 [ 1st option ]

Step-by-step explanation:

Consider any two points , say

(1,3) (2,1)

Firstly let's find the slope of the line as ,

=> m = y₁ - y₂ / x₁ - x₂

=> m = 3-1 / 1-2

=> m = 2/-1

=> m = -2

Third point is, (3 , -1) . Using slope point form .

=> y - y₁ = m ( x - x₁ )

=> y - (-1) = -2( x - 3)

=> y + 1 = -2x +6

=> y +2x +1-6=0

=> y +2x -5 = 0

=> y = -2x + 5

On looking at options first one is correct

Hence the equation of line is y = -2x + 5.

Sandy has a total of 35 coins in her money jar. If Sandy's jar contains only nickels and dimes and the value ol
the coins is $2.50, how many nickels does Sandy have?

Answers

you'll have to solve simultaneously

let nickel be x, dime be y

x + y = 35 ... ( 1 )

5x + 10 y = 250
5 ( x + 2y ) = 250
x + 2y = 50 ... ( 2 )

in ( 1 )
x = 35 - y ( 3 )

sub ( 3 ) into ( 2 )
( 35 - y ) + 2y = 50
y = 15

sub y into ( 1 )
x + y = 35
x + 15 = 35
x = 20

therefore, Sandy has 20 nickels and 15 dimes

The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

Profit = total revenue - total cost

total revenue = 80 x b

Since there are no restrictions on the strings, we can think of this problem as drawing 5 random digits in sequence. There is a 9/10 chance each time we draw to NOT get a 4. Every time we draw, we multiply by 9/10 again until we've draw 5 digits. Thus, the answer is (9/10)^5 :)

Answers

Answer:

[tex]Pr = 0.59049[/tex]

Step-by-step explanation:

See Comment for Complete Question

Given that A has 5 digits. A digit in A can be chosen from 0 to 9 (10 digits).

However, selection without 4 means that we can only select from 0 to 3 and 5 to 9 (altogether, that is 9 digits)

The probability of selecting a number other than 4 in each of the digit is:

[tex]1st \to \frac{9}{10}[/tex]

[tex]2nd \to \frac{9}{10}[/tex]

[tex]3rd \to \frac{9}{10}[/tex]

[tex]4th \to \frac{9}{10}[/tex]

[tex]5th \to \frac{9}{10}[/tex]

So, the required probability is:

[tex]Pr = 1st * 2nd * 3rd * 4th * 5th[/tex]

[tex]Pr = \frac{9}{10} *\frac{9}{10} *\frac{9}{10} *\frac{9}{10} *\frac{9}{10}[/tex]

[tex]Pr = \frac{9^5}{10^5}[/tex]

[tex]Pr = \frac{59049}{100000}[/tex]

[tex]Pr = 0.59049[/tex]

.Find the point of intersection of the pair of lines. x + 5y = 8, -x + 2y = -1

Answers

Answer:

the point of interception is where the graphs meets

in this case we will solve using substition method

x + 5y = 8 .... 1

-x + 2y = -1 .....2

solve for the equation

x = 8 - 5y ...... 3

solve the equation in equation 2

-x + 2y = -1

-(8-5y ) + 2y = -1

-8 +5y + 2y = -1

7y = -1 + 8

7y = 7

divided by 7 on both sides

y = 1

solve the value of y in equation 3

x = 8 - 5y

x = 8 - 5(1)

x = 8 -5

x = 3
