Answer:

We have the equations:

1.15x + 0.65y = 8.90

and

x − 3y = -15

First, let's write them in the slope-intercept form:

The first one will be:

y = -(1.15/0.65)*x + 8.90/0.65  

The second:

y = (1/3)*x + 15/3 = (1/3)*x + 5.

then our system is:

y = -(1.15/0.65)*x + 8.90/0.65  

y  = (1/3)*x + 5.

To graph each line, you can just evaluate the line in two points (for x = 0 and x = 1, for example) and then locate those points in the coordinate axis, and then draw a line that connects them.

For example with the second line:

y(0) = (1/3)*0 + 5 = 5

then we have the point (0,5)

and

y(3) = (1/3)*3 + 5 = 8

Then we have the point (3,8)

With the first equation may be a little harder, as the coefficients are not whole numbers, we can rewrite it as:

y = (1.15/0.65)*x + 8.90/0.65  = (115/65)*x + (890/65)

Where i multiplied and divided by 100 the numerators and denominators in the right side, so now is easier to work with it.

The points you can use are:

y(0) =  (115/65)*0 + (890/65) = 13.7

the point is (0, 13.7)

and:

y(1) = (115/65)*1 + (890/65) = 15.5

The point is (1, 15.5)

Below you can see the graphs of both functions:

blue: y = -(1.15/0.65)*x + 8.90/0.65

red: y  = (1/3)*x + 5

The answer is in the picture below!

Answer:

I think it is 0.257 kg

Step-by-step explanation:

To change units from the gram to kilogram, you need to divide by 1000, because 1kg=1000g:

257÷1000= 0.257 Kg

The mass of the fruits in kilogram (kg) is 3.556 kg

Given:

Mass of the bag containing fruits = 3.813 kg

Mass of the empty bag = 257 g

convert

257 g to kg

257 g = 0.257 kg

Mass of the bc fruits = Mass of the bag containing fruits - Mass of the empty bag

= 3.813 kg - 0.257 kg

= 3.556 kg

Therefore, the mass of the fruits in kilogram is 3.556 kg

Answer:

x + 2y = 13}(add the both eqns)

-x + y = 5}

x +(-x) = 0

2y + y = 3y

13 + 5 = 18

then,

3y = 18

y = 6

from

x + 2y = 13

x = 13 - 2(6)

x = 1

Answer:

x = 19

Step-by-step explanation:

l, m and n are the parallel lines.

Two transversal lines are intersecting these parallel lines.

By Intercept theorem,

Lengths of intercepts between the parallel lines are proportional.

[tex]\frac{38}{8}=\frac{x}{4}[/tex]

x = [tex]\frac{4\times 38}{8}[/tex]

x = 19

Therefore, x = 19 will be the answer.

Answer:

c. The slope is -11 and the y-intercept is (0,6)

Step-by-step explanation:

the slope formula is y=mx+b, where m= slope, and b is the y-intercept. so that would mean -11x is the slope and (0,6) is the y-intercept

so that would make c the correct answer.

Answer:

The answer is B, S=20R+60.

Step-by-step explanation:

To check if the answer is true we can plug in the numbers. For the first line, it would be S = 20(20) + 60. 20 times 20 = 400, and 400 + 60 is 460. 460 is the number of seats in the row so the answer is true.

Answer:

the answer is 0.204

Step-by-step explanation:

The probability that if 5 tires are inspected, exactly 1 has a defect is 0.204

The probability that a tire is defect is given as:

p = 5%

The required probability is then calculated using:

[tex]P(x) = ^nC_x * p^x * (1 - p)^{n - x}[/tex]

Where:

n = 5 --- number of tires

x = 1 ---number of tires with defect

So, we have:'

[tex]P(1) = ^5C_1 * (5\%)^1 * (1 - 5\%)^{5 - 1}[/tex]

This gives

[tex]P(1) = 5 * (5\%) * (1 - 5\%)^4[/tex]

Evaluate the product

P(1) = 0.204

Hence, the probability that if 5 tires are inspected, exactly 1 has a defect is 0.204
