9x+5y=8
3x–y=4
what is the y-value of the solution to the system?

Answers

Answer 1

Answer:

y=7.51

Step-by-step explanation:

First, you have to simplify one of the equations down

3x-y=4

y=-4+3x

Second, you insert the value of y into the other equation and then solve for x

9x+5(-4+3x)=8

9x-20+15x=8

24x=28

x=1.17

Last, insert the value of x into the original equation and then solve for y

y=4+3(1.17)

y=7.51

Identify the type of function that models the situation below: The cost of mailing a letter is $0.37 for the first ounce and $0.23 for each additional ounce or portion thereof. a. greatest integer function c. absolute value function b. step function

Answers

Answer:

The correct option is;

Step function

Step-by-step explanation:

The given information are;

The cost of mailing a letter for the first ounce= $0.37

The cost for each additional ounce = $0.23

Therefore, the cost of mailing a letter can be found from the relation;

y = (N-1) × $0.23 + $0.37

The step function can be represented as follows;

f(x) = a[b(x - h)] + k

Where;

(h. k) = The starting points

a = The vertical step separation

b = The horizontal step separation

Therefore, in the question, we have;

a = $0.23

b  = 1

h = 1

k = $0.37

Which gives;

f(x) = $0.23 × [1(x - 1)] + $0.37 = $0.23 × (x - 1) + $0.37

f(x) = $0.23 × (x - 1) + $0.37 which is similar to y = (N-1) × $0.23 + $0.37

Therefore the function that models the situation is step function.

Answer:

  |h -1.7| ≤ 0.5

Step-by-step explanation:

Consider the absolute value inequality ...

  |x -a| ≤ b

This is fully equivalent to ...

  -b ≤ x -a ≤ b

because the value between the absolute value bars can be either positive or negative. If we add a to this, we get ...

  -b +a ≤ x b +a

__

Comparing this to your given expression, we find ...

  -b +a = 1.2

  b + a = 2.2

If we add these equations together, we get ...

  0 +2a = 3.4

  a = 1.7 . . . . . . . the midpoint of the interval [1.2, 2.2]

  b = 2.2 -a = 0.5 . . . . half the width of the interval [1.2, 2.2]

So, your absolute value inequality is ...

  |h -1.7| ≤ 0.5

on a school trip, 56 girls and 91 boys go to south Korea they were divided into groups as possible so that each group has an equal number of girls and boy in each group, how many in each group?

Answers

Answer:

21

Step-by-step explanation:

You must find a number that will divide into the total of the girls and boys and come up with an even number.  By looking at the numbers, you can see that both 56 and 91 will divide evenly by 7. The common denominator for both calculations is 7.

56/7=8 girls  

91/7= 13 boys

Add 8 girls and 13 boys and you will have 21 in each group.  That way, all groups are equally boys and girls.

8+13=21

8x11=(8x10)+(1x10) how can I make it true?

Answers

Since 8x 11 =88, 8x10=80 and 1x10 =10. It can not be true because 88 and 90 are not the same

By applying subtraction property in RHS of the expression, we make it true.

What is mean by Subtraction?

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

The expression is,

⇒ 8 × 11 = (8 × 10) + (1 × 10)

Now, Take LHS of the expression,

⇒ 8 × 11

⇒ 88

And, By RHS;

⇒  (8 × 10) + (1 × 10)

⇒  (80) + (10)

⇒ 90

Subtract 2;

⇒ 90 - 2

⇒ 88

Thus, By subtracting 2 from RHS of the expression, we make it true.

In one baseball season, Peter hit twice the difference of the number of home runs Alice hit and 6. Altogether, they hit 18 home runs. How many home runs did each player hit that season.

Answers

Answer:

Peter hit 12 home runs and alice hit 6 home runs

Step-by-step explanation:

this is right because if Peter hit 6 and then he hit twice the amount that would bring his total to 12 due to 6 x 2 = 12 and if together they hit 18 home runs that would mean you want to subtract the total from Peter's and that would be explained as 18-12=6 and the 6 left over would leave you with alice number of home runs.

90°  90°

Step-by-step explanation:

The measure of each angle of the reflected polygon is same as the corresponding angle of the original one.

What is the reflection of polygon about a line?

By reflection about a line, the polygon changes its position such that the distance of every point from the original one will be the same as the distance from every corresponding point of the reflected one from that line.

So according to the question,

Let polygon ABCD is reflected about line GH then the reflected polygon will be A'B'C'D'

Let ∠ABC= 120°

∠BCD= 80°

∠CDA= 70°

∠DAC= 90°

Now if we measure the corresponding angle of the reflected polygon A'B'C'D', then the reflected corresponding angle will be

∠A'B'C'= 120°

∠B'C'D'= 80°

∠C'D'A'= 70°

∠D'A'C'= 90°

Therefore the measure of each angle of the reflected polygon is the same as the corresponding angle of the original one.

You roll a 6-sided die two times.
What is the probability of rolling a divisor of 10 and then rolling a prime number?

Write your answer as a decimal.

Answers

Answer: 0.25

Step-by-step explanation:

The numbers on a 6-sided dice are 1,2,3,4,5, and 6.

The probability of rolling a divisor of 10 is 3/6 because 1, 2, and 5 are the divisors of 10 out of 1 to 6.

The probability of rolling a prime number is 3/6 because 2, 3, and 5 are prime numbers out of 1 to 6.

To know the probability of both of these, you will have to multiply them:

3/6 x 3/6 = 9/36 or 1/4

1/4 as a decimal is 0.25

The length of a reſtangle is 3 ft more than the width. The perimeter is is 62 ft. Find the length and
width of the rectangle.

Answers

Solution:-

Given that length of rectangle is 3 ft more than its breadth . Also , perimeter of rectangle is 62 ft . And we are asked to find the Length and breadth .

So , we know we can find perimeter of rectangle as :

[tex]\boxed{\red{\bf \dag Permiter_{rectangle}=2(l+b)}}[/tex]

Now , let us take the

Breadth be x .Length be x + 3 .

So , as per Question :

[tex]\tt :\implies Perimeter=2(l+b)[/tex]

[tex]\tt :\implies 62 \cancel{ft.} = 2( x + 3 + x ) \cancel{ft.} [/tex]

[tex]\tt :\implies 62 = 2 ( 2x + 3 ) [/tex]

[tex]\tt :\implies 62 = 4x + 6 [/tex]

[tex]\tt :\implies 4x = 62 - 6 [/tex]

[tex]\tt :\implies4x = 56. [/tex]

[tex]\tt :\implies x =\dfrac{\cancel{56}}{\cancel{4}} [/tex]

[tex]\underline{\boxed{\red{\tt\longmapsto \:\:x\:\:=\:\:14}}}[/tex]

Hence we got x as 14 .

So , let's put the value in our assumption:

[tex]\boxed{\green{\bf \pink{\dag} Length = x + 3 = 14 + 3 = 17 ft.}}[/tex]

[tex]\boxed{\green{\bf \pink{\dag} Breadth = x = 14 ft.}}[/tex]
