Use the substitution method.

Answers

Answer 1

Answer:

y=2x-6. ---------(1)

4x-2y=14. --------(2)

substituting equation 2 in 1

4x-2(2x-6)=14

4x-4x+12=14

so it has no solution

Ok so 2(x+1) would be two times the sum of a number and one. “Sum of a number and one” is just “x+1” and then it’s two times that because the two is outside of the parentheses.

And then 2x+1 would be the product of two and a number increased by 1. The product is two and a number is 2x and then increased by 1 is the +1

2x+5+3x+6= combine like terms to simplify each expression

Find the slope using points: (2,5) and (8,9)

Answers

Answer: The slope is 2/3:)

Step-by-step explanation: (2,5) and (8,9)

9-5 =4 /2=2

8-2 =6 /2= 3

Answer: 2/3 or 4/6.

Step-by-step explanation:

Slope = (y2-y1) / (x2-x1)

(9 - 5) / (8-2)

= 4/6, which reduces to 2/3.

The slope of the line between the two given points is 4/6, or 2/3 in simplest terms.

so first you have to subtract 12 from both sides
this will give you
:square root(1-5x)=6
then we must square both sides to get

we then subtract 1
:-5x=35
and divide by -5 to get a final answer of

Answers

Answer:

21.53 in of fabric on headbands

7.67 in of fabric on wristbands.

Step-by-step explanation:

Step one:

given data

the total amount of person players plus coaches= 27+4= 31

for each person, she uses = 667.43/31= 21.53 in of fabric on headbands

She also uses 237.87inches of fabric on wristbands for just the players

For each player, she will use= 237.87/31= 7.67 in of fabric

Hence for each player, she used

21.53 in of fabric on headbands

7.67 in of fabric on wristbands

From the question we have

[tex]d = \sqrt{ ({ - 9 - - 10})^{2} + ({1 - - 11})^{2} } \\ = \sqrt{ ({ - 9 + 10})^{2} + ({1 + 11})^{2} } \\ = \sqrt{ {1}^{2} + {12}^{2} } \\ = \sqrt{1 + 144} \\ = \sqrt{145} \: \: \: \: \: \: \: \: \\ = 12.041594[/tex]

there's a property for Alternate Interior Angles

Answer:

Choice B

Step-by-step explanation:

The reason why < 3 is equal to < 6 is because they are alternate interior angles.

The first choice are supplementary angles they add up to 180 so they can't be equal.

The third one is false because we don't actually know the measurements of the angles but they both need to be 45° to add up to 90 since they are equal to each other.

The last one is also incorrect because they are vertical angles just like the third choice and they aren't on a line so they can't add up to 180.

5. Choose the best answer.
Find the slope and y-intercept of the equation; then choose the equation in slope-Intercept form.
3.3x– 3y = 2.4
slope
y -intercept
slope-intercept form

Answers

The slope-intercept form: y = mx + b

So we need to "solve" given equation for y

3.3x - 3y = 2.4           {subtracting 3.3x from both sides}

- 3y = 2.4 - 3.3x        {dividing both sides by (-3)}

  y = -0.8 + 1.1x

Therefore:

Slope:                         m = 1.1y -intercept :               b = - 0.8slope-intercept form:   y = 1.1x - 0.8
