Answer:  The required solution is [tex]x\leq4.[/tex]

Step-by-step explanation:  We are given to solve the following inequality :

[tex]8+4(x-3)+3x\leq24~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

To solve the given inequality, we must find the value of the unknown variable x.

From inequality (i), we have

[tex]8+4(x-3)+3x\leq24\\\\\Rightarrow 8+4x-12+3x\leq24\\\\\Rightarrow 7x-4\leq24\\\\\Rightarrow 7x\leq24+4\\\\\Rightarrow 7x\leq28\\\\\Rightarrow x\leq\dfrac{28}{7}\\\\\Rightarrow x\leq4.[/tex]

Thus, the required solution is [tex]x\leq4.[/tex]

Answer:

1. Yes

2. Yes

Step-by-step explanation:

1. Lets test Lisa's different solution. Lets times 5 to the first equation:

[tex]5\cdot{x}+10\cdot{y}=35[/tex]

and 2 times the second equation:

[tex]4\cdot{x}-10\cdot{y}=10[/tex]

lets add the two equations:

[tex]9\cdot{x}=45[/tex]

[tex]x=5[/tex]

The second method is multiplying the first equation by -2:

[tex]-2\cdot{x}-4\cdot{y}=-14[/tex]

and add the second equation:

[tex]-9\cdot{y}=-9[/tex]

[tex]y=1[tex]

Substitute into equation 1:

[tex]x+2\cdot{1}=7[/tex]

[tex]x=5[/tex]

The answer to Lisa's question is yes she wull get the same solution if she uses a different method.

2. Yes, The answer would change if the same amout of x and y values are the same and therefore we cannot solve for x and y. If there was infinitely many solutions we would have quadratic equations.

Answer:

The equation of required line is y=3x+2.

Step-by-step explanation:

The slope intercept form of a line is

[tex]y=mx+b[/tex]            ..... (1)

where, m is slope and b is y-intercept.

We need to find the equation of line whose slope is m=3 and the y-intercept is (0,2).

Substitute m=3 and b=2 in equation (1), to find the equation of required line.

[tex]y=(3)x+(2)[/tex]

[tex]y=3x+2[/tex]

Therefore the equation of required line is y=3x+2.

The equation for the line hose gradient/slope is 3 and a y-intercept of (0, 2) is y = 3x + 2

Equation of a straight line can be found when given:

The equation of the straight line with gradient m, passing through a point (x1,y1) is  

y-y1 = m(x-x1)

We are given the y-intercept as (0, 2) and the slope is 3  

Therefore;  

To get the equation, we take another point (x,y)  

(y-2)/(x-0) = 3

y-2 = 3x  

y= 3x + 2

The correct statement describes how the slope relates to the height of the water in the pool is,

The height of the water increases by 2 inches per minute.

Given that,

The slope of the line through the points is 2.

And, the slope relates to the height of the water in the pool.

Here, a table for the height of the water in a pool is shown.

Since the slope of the line through the points is 2.

Hence, It means that,

if the height of the water is increased by 4 inches for 2 minutes, then for 1 minute is increased,

4/2 = 2 inches.

So, the correct statement is,

The difference between the squares of twenty and thirteen will be 234.

To subtract in mathematics is to take something away from a group or a number of objects.

In other meaning, subtraction is a mathematical operation such that two values are going to subtract and give a resultant value.

The group's total number of items decreases or becomes lower when we subtract from it.

Square of twenty = 20²

20² = 20 × 20 = 400

Square of thirteen = 13²

13² = 13 × 13 = 169

Difference ⇒ 400 - 169 = 231.

Final answer:

The area of the inner square is x squared. This is determined by the rule that the ratio of areas of similar figures is the square of the scale factor, with the larger square having dimensions and area four times that of the smaller square.

Explanation:

Considering a larger square with an area of 4x², and given that the dimensions of this square are twice that of a smaller square, we can derive the area of the smaller square by understanding the relationships between the scale factor and the area of similar figures. If Marta's original square has a side length of 4 inches, doubling the dimensions gives a side length of 8 inches for the larger square.

The scale factor for the sides is 2, but when considering area, the scale factor is squared. Consequently, the area of the larger square, which is 8 inches by 8 inches, will be 64 square inches. This area is four times larger than the area of the smaller square, which is 16 square inches (4 inches x 4 inches). Thus, the rule that the ratio of areas of similar figures is the square of the scale factor applies. The area of the inner square would be equivalent to the area of the outer square divided by 4, which in our case, with an outer square area of 4x², leads to an inner square area of x².

Amount of energy released during Earthquake is [tex]5.23*10^{6} kilowatt[/tex]

The Richter scale is used to measure the magnitude of a earthquake. The magnitude R is,  

    [tex]R=0.65log(0.39E)+1.45[/tex]         E is the energy (measured in kilowatt-hours) released by the earthquake.

Answer: We can find the measurement of the angle M using that the sum of the interior angles in any triangle is equal to 180°, then:

m<M=98°

Solution:

m<M=(3x-16)°

To find m<M we need "x".

m<N=x°

m<O=(x+6)°

The sum of  the interior angles of any triangle is equal to 180°:

m<M + m<N + m<O = 180°

Replacing the angles:

(3x-16)° + x° + (x+6)° = 180°

We have one equation with one variable "x", then we can solve for x. Adding the terms:

(3x-16+x+x+6)°=180°

3x-16+x+x+6=180

Adding similar terms:

5x-10=180

Adding 10 both sides of the equation:

5x-10+10=180+10

5x=190

Dividing both sides of the equation by 5:

5x/5=190/5

x=38

Then:

m<M=(3x-16)°

Replacing x by 38 in the formula above:

m<M=(3(38)-16)°

m<M=(114-16)°

m<M=98°

Step-by-step explanation:

We  have to find an expression which illustrate the associative property.

We know that associative property of addition  of three numbers a, b and c

[tex]a+(b+c)=(a+b)+c[/tex]

A.(3+19)-12=(3+12)-19

(3+19)-12=10

(3+12)-19=-4

It is not associative property of addition because both sides are not equal.

B.3+(19-12)=3+(19+12)

3+(19-12)=10

3+(19+12)=34

It is false because both sides are not equal .

C.(3+19)-12=3+(19-12)

(3+19)-12=10

3+(19-12)=10

It is illustrate the associative property of addition.

D.3+(19-12)=3-(19+12)

3+(19-12)=10

3-(19+12)=-28

Answer:

JY = 14

Step-by-step explanation:

Given :  Y is between points J and A.

and JA = 17 and YA = 3.                            

We have to find the length of JY.

Since, Y is between points J and A.

So,  JA = JY + YA

Substitute,  JA = 17 and YA = 3.          

We have,

17 = JY + 3

Solve for JY, we have,

JY = 17 - 3 = 14

Thus, JY = 14
