Answer:

The first: y = -25x + 180

Step-by-step explanation:

In every equation b = 170, so

The equation is y =mx + 170

On the line on the graph, for x=2 we have y = 120,so:

120 = m×2 + 170

-50 = 2m

m = 25

Therefore the equation is:

y = -25x + 180

What is the answer to this equation -14=d/15

Answers

Answer:

d=-210

Step-by-step explanation:

multiply 15 to both sides

-14*15 =-210

the 15 on the side with d cancels

Now you have d=-210

You missed 1 4questions on your math test and 3 out of 10 on your history test. In which class did you earn a higher percentage on your quiz?

Answers

Answer:

You got a higher score on your math test.

AJKM – AJKL
ΔJKM - ΔKML
Ο ΔJMK - ΔJKL
Ο ΔJMK - ΔKML

Answers

Answer:A, D, E

Step-by-step explanation:

ΔJKL and ΔJKM are similar triangles and ΔJKL and ΔKML are similar triangles. Therefore, options A and B are the correct answers.

What are similar triangles?

Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.

From the given figure, ΔJKL, ΔJKM and ΔKML are right angle triangles.

Now, consider ΔJKL and ΔJKM

∠JMK=∠JKL (Measure of angle is equal to 90°)

∠KJM=∠KJL (Reflexive property)

ΔJKL and ΔJKM are similar triangles

Consider ΔJKL and ΔKML

∠KML=∠JKL (Measure of angle is equal to 90°)

∠JLK=∠MLK (Reflexive property)

ΔJKL and ΔKML are similar triangles

Therefore, options A and B are the correct answers.

Solve the equation for x:
-3(x + 4) + 5x = 24

Answers

Answer:

[tex]-3(x + 4) + 5x = 24\\\\-3x - 12 + 5x = 24\\\\2x - 12 = 24\\\\2x = 36\\\\x = 18[/tex]

The solution for x in this equation is 18.

Answer:

x = 18

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define

-3(x + 4) + 5x = 24

Step 2: Solve for x

Distribute -3: -3x - 12 + 5x = 24Combine like terms: 2x - 12 = 24Isolate x term: 2x = 36Isolate x: x = 18

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x: -3(18 + 4) + 5(18) = 24Add: -3(22) + 5(18) = 24Multiply: -66 + 90 = 24Add: 24 = 24

Here we see that 24 does indeed equal 24.

∴ x = 18 is the solution to the equation.

This equation is the total height adding 5 for the top border and 5 for the bottom border. Then multiplying the total height by the width of the border 5, time 2 because there are two sides that are tall Then adding 5 times two widths.

Answers

Answer:

x = x + 7

Step-by-step explanation:

In this equation, it is saying that x is equal to itself plus something else (7). This equation does not make sense at all because x cannot equal to something that is bigger or smaller than itself. If 7 is added to x, like the right-hand side of the equation, it cannot be equal to x from the left-hand side of the equation, so there is no solution to the value of x in this equation.

A gift basket has 2 soaps and 5 lotions and costs $20. A second basket has 6 spas and 15 lotions and cost $60. Is it possible to determine the price of the soap?

Answers

A second basket has 6 spas--- I think you mean 6 soaps , so i will work with that

Answer:it is not possible to determine the price of the soap with the information given.

Step-by-step explanation:

Let s0ap be represented as x

and lotion be represented as y

2 soaps and 5 lotions costing $20 gives us equation 1 as

2 x+ 5y= 20-------- equation 1

second basket with 6 soaps and 15 lotions and costing $60 gives us equation 2 as

6x + 15y= 60------equation 2

Step 2 -- Solving

2 x+ 5y= 20-------- equation 1

6x + 15y= 60--------equation 2

BY elimination method, we multiply equation 1 by (3)

2x + 5y= 20 x (3)

6x + 15y=60-------equation 3

Subtraction of equation 3 from equation 2 gives us

6x + 15y=60-------equation 3

-6x + 15y= 60--------equation 2

0x +0y=0 which is no solution

Therefore it is not possible to determine the price of the soap
