-5y + 4x = 4
-7y - 10x = - 10

Answers

Answer 1

Answer:

The answer is    

Step-by-step explanation:

use system of equations and substitution.

to solve this equation, one variable needs to be cancelled out to solve for the other.

[tex]-5y+4y=4\\-7y-10x=-10\\[/tex]

looking at this problem, we can manipulate -5 and -7 to equal 35 and -35 to get rid of the variable x to solve for y.

[tex]-7(-5y+4x=4)\\5(-7y-10x=-10)\\\\35y-28x=-28\\-35y-50x=-50[/tex]

with this, we can cancel out 35x and -35x.

[tex]-28x=-28\\-50x=-50[/tex]

manipulate the equation to equal x.

[tex]x=1\\x=1.[/tex]

plug 1 for x back into one of the equations to solve for y.

[tex]-5y+4(1)=4\\-5y+4=4\\-5y=0\\y=0[/tex]

therefore, (1,0)

hope this helps :)

Step-by-step explanation:

Let's solve for f.

y=−3x+2f(6)

Step 1: Flip the equation.

12f−3x=y

Step 2: Add 3x to both sides.

12f−3x+3x=y+3x

12f=3x+y

Step 3: Divide both sides by 12.

Elena collects 112 specimens of beetle and records their lengths for an ecology research project. When she

returns to the laboratory, Elena finds that she incorrectly recorded one of lengths of the beetles as 122

centimeters (about 4 feet). What should she do with the outlier, 122 centimeters, when she analyzes her data?

A.

She should exchange the recording error with the average length from her other measurements.

B. She should take the 4 foot long beetle to Guinness Book of Records

C.She should go back and remeasure all of her specimens again to find the error. If she can't do this, she should eliminate the

outlier from her analysis, because this is an error in recording.

Answers

Answer:

The correct option is;

C. She should go back and remeasure all of her specimens again to find the error. If she can't do this, she should eliminate the outlier from the analysis, because this is an error in recording

Step-by-step explanation:

In order to minimize error in measurement, some valuable steps includes;

1) Perform a double check on all measurements to ensure that the measurements recorded are accurate

2) Ensure proper training before taking measurements

3) Measurements should only be taken under controlled conditions

4) Separate the entire population into smaller groups for proper recording

5) Have a second observer double check the records

True or False: If two angles are vertical, then they are congruent

Answers

Answer:

True

Step-by-step explanation:

Vertical angles should always be congruent.

I hope this helps

if you could, feel free to mark me Brainliest it would be much appreciated :D

The statement "if two angles are vertical, then they are congruent" is true.

Vertical angles are formed when two lines intersect.

When two lines intersect, they create four angles at the intersection point.

Vertical angles are the angles that are opposite each other when two lines intersect.

These angles have equal measures, which means they are congruent.

If there are two vertical angles, their measures will be the same, and therefore, they are congruent.

Hence, the statement "if two angles are vertical, then they are congruent" is true.
