Answer:

Step-by-step explanation:

m just means measure. So the question is asking you what is the MEASURE of the ANGLE AEB.

Since angles AEB and CED are vertical angles, you can set the two expressions equal to each other and solve for X.

1) 3x + 54 = 7x - 30

2) 54 = 4x - 30

3) 84 = 4x

4) x = 21

3(21) + 54 = 117

m∠AEB = 117°

The equation for profit in slope-intercept form is written as y = 26x - 584

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation is given as y = mx + c

In this problem, the constant or fixed value is the amount he spent on the equipment and the slope is the amount he charges per hour.

The equation of profit can be represented as y = 26x - 584

Answer:

Line W's equation is y= 1/2x - 8

Step-by-step explanation:

The equation which represents the population, P after t months is:

y = 1600(1+ 0.25)^t.

Given,

A population of beetles grows by 25% every month.

the beetle population starts with 1,600 beetles,

we are asked to determine the equation which represents the population, P after t months.

The equation for the population is:

Pf = Pi(1-r)^t

where pf = final value

pi = initial value

r = growth factor

t = time in years.

substitute the values in the equations.

let y represent the final population after t years.

r = 25%

convert percentage to decimal.

r = 0.25

y = 1600(1+ 0.25)^t

Hence we get the required answer.

The annual interest rate is 1.2%

The principal amount = $425

The total interest her earned = $10.20

The final amount = 425 + 10.20

= $435.2

Time period = 2 years

The simple interest

A = P(1 + rt)

Where A is the final amount

P is principal amount

r is the interest rate

t is the time period

Substitute the values in the equation

435.2 = 425(1 + r×2)

1 + 2r = 435.2 / 425

Divide the terms

1 + 2r = 1.024

2r = 1.024 - 1

2r = 0.024

r = 0.024/2

Divide the terms

The required solution will be -30 which is expressed as an integer.

To represent this in a general context, we may utilize functions that are referred to in terms of the number tossed.

We know that if the number he gets is an even number, he will get 5 times the number.

As a result, the function for when the integer x is even is f(x) = 5x.

If the number is an odd number, he will lose 10 times the number.

As a result, the function for when the integer x is odd is f(x)=-10x.

Finally, Joe tosses a 3, which is an odd integer, hence the function we will represent is f(x) = - 10x.

⇒ f(3) = -10(3) = -30

Thus, the required solution will be -30 which is expressed as an integer.

The measure of angle KJL from the given figure is 84°.

Given that, 3(m∠LJM)=2(m∠KJL) and m∠KJM=140°.

An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle.

Here, m∠KJM=m∠LJM+m∠KJL

Now, (m∠LJM)=2/3 (m∠KJL)

140°= 2/3 (m∠KJL) + m∠KJL

⇒ [2(m∠KJL)+3(m∠KJL)]/3 = 140°

⇒ 5m∠KJL=420°

⇒ m∠KJL=420°/5

2. The second figure posses the ASA property.

3. The third figure posses the hypotenuse length property.

4. The fourth figure posses the SAS property.

Given:

1. The first figure shows the SSS property.

Side-Side-Side criterion is referred to as the SSS criterion. According to this standard, two triangles are congruent if their respective triangles' three sides are equal to one another.

hence the two triangles are congruent.

2. The second figure posses the ASA property.

Angle-Side-Angle criterion is also known as ASA criterion. According to the ASA criterion, two triangles are congruent if any two of their included sides and related angles are equivalent in size to those of the other triangle.

hence the two triangles are congruent.

3. The third figure posses the hypotenuse length properety.

RHS criterion stands for right angle-hypotenuse-side congruence criterion. Under this criterion, two triangles are congruent, if the hypotenuse and side of one right-angled triangle are equal to the hypotenuse and the corresponding side of another right-angled triangle.

hence the two triangles are congruent.

4. The fourth figure posses the SAS property.

Side-Angle-Side criterion is referred to as the SAS criterion. According to this standard, two triangles are said to be congruent if their matching sides and included angles are the same on each side of each other.

Step-by-step explanation:2x+9y = -26

-3x-7y = 13

Multiply the first equation by 3

6x +27y = -78

Multiply the second equation by 2

2(-3x-7y = 13)

-6x -14y = 26

Add these two equations together

6x +27y = -78

-6x -14y = 26

13y = -52

Divide by 13

13y/13 = -52/13

y = -4
