Answer:

[tex](\frac{5}{2}, 2)[/tex]

Step-by-step explanation:

Hi there!

We are given this system of equations:

2x + y = 7

2x - 3y = -1

And we want to find the solution

There are multiply ways to solve systems of equations, but let's solve this one by elimination, where we will add the two equations together to clear one of them, solve for the un-cleared variable, and then use the value of the un-cleared variable to solve for the cleared one

Before clearing a variable, we need to make sure that the signs on the variables are opposites; for example, -3 and 3, which will add together to get 0

We can multiply the equations beforehand if needed in order to manipulate the numbers.

For example, we can multiply the second equation by -1 in order to switch the signs of each number in that equation:

-1(2x-3y=-1)

-2x+3y=1

Now the signs in front of x are 2 and -2, so we can add the equations together to clear them:

2x + y = 7

-2x + 3y = 1

Add the equations together

4y = 8

Divide both sides by 4

y=2

Now let's use 2 as y to solve for x

In the first equation, substitute 2 for y:

2x + 2 = 7

Subtract 2 from both sides

2x = 5

Divide both sides by 2

[tex]x=\frac{5}{2}[/tex]

As a point, the answer is [tex](\frac{5}{2}, 2)[/tex]

Hope this helps!

Answer:

a. 1 1/2 (or 3/2)

b. 2/3

c. 1

d. 1

Step-by-step explanation:

Part A: (1,1) (7,5)

To determine the slope, you will use the equation m=(y2-y1)/(x2-x1). Keep in mind that it doesn't matter what point you use for (x1, y1) or (x2, y2).

Let's plug in the numbers for part a:

m=(7-1)/(5-1)

Let's then solve the problems inside the parentheses:

m=6/4

And finally, we simplify:

m=3/2 (or 1 1/2 depending on what your teacher wants for an answer)

For these others, I will just go through the steps and not explain them, if you need help or don't understand something I'm doing, either look back at what I did for part a or comment on this answer.

Part B: (1,1) (5,7)

m=(5-1)/(7-1)

m=(4/6)

m=2/3

Part C: (2,5) (-1,2)

m=(-1-2)/(2-5)

m=(-3/-3)

m=1

Part D: (2,5) (-7,-4)

m=(-7-2)/(-4-5)

m=(-9/-9)

m=1

Answer:

Angle 2 = 55

Angle 1 = 125

Step-by-step explanation:

Considering the line vertical lines are parallel:

Angle 2 and angle with measure of 125 are supplementary and their sum is = 180

So m<2 = 180 - 125 = 55

For angle 1:

Again since the vertical lines are parallel:

Angle 1 and angle with given measure 125 are alternate and has same measurement.

Answer:

Angle 2= 55 degrees

angle 1= 125 degrees

Step-by-step explanation:

Angle 2 uses SA, 180-125=55

angle 1 is parallel to the 125 degree line

Answer:

0.05 in decimal form or 1/20

Step-by-step explanation:

Since there are 20 blocks, we are going to divide 1 by 20.

Result: 00.5

To get it in fraction form we are going to multiply 1/4 by 1/5 and get 1/ 20 because 4 x 5 = 20. There is no way to simplify this.

Therefore, your answer would be 1/20.

Answer:

700=25x28

Step-by-step explanation:

The product of the two given numbers is 700.

The given expression is 25 × 28.

We need to find the product of these two numbers in different ways.

The distributive property of multiplication over addition states that multiplying the sum of two or more addends by a number gives the same result as multiplying each addend individually by the number and then adding the products together. This property of multiplication over addition is used when we need to multiply a number by a sum.

Now, direct multiplication 25 × 28=700

Using distributive property we get 25 × (20+8)

=25 × 20 + 25 × 8

=500 + 200

=700

Therefore, the product of two given numbers is 700.

[tex] (3+18+6)+(-4-5)[/tex]

[tex]( 27) + (-9)[/tex]

[tex] 18[/tex]

Step-by-step explanation:

let the 2 numbers be x and x + 4 as their deference is 4.

their sum = 50

now,

→ x + x + 4 = 50

→ 2x + 4 = 50

→ 2x = 50 - 4 = 46

→ x = 46/2 = 23

therefore two numbers are,

x = 23

x + 4 = 23 + 4 = 27

hope this answer helps you dear...take care and may u have a great day ahead!

Step-by-step explanation:

x + y = 50

x - y = 4

x = y + 4

let's use that as substitute in the first equation

y + 4 + y = 50

2y = 46

y = 46/2 = 23

=>

x = y + 4 = 23 + 4 = 27

the 2 numbers are 23 and 27.

Answer:

Slope: 2/3

y-intercept: -3

Step-by-step explanation:

Subtracting both sides of the equation by 3 to make it in 'y=mx+c' form:

y + 3 - 3 = 2/3x - 3

y = 2/3x - 3

Seeing this,

m = 2/3

c = -3

Since m is the slope, the slope is 2/3

Since c is the y-intercept, the y-intercept is -3
