find the ordered pair (x,y) that is a solution to the equation

x-4y=8

Answers

Answer:

(4,-1)

Step-by-step explanation:

x-4y=8

-4y=-x+8

y=1/4x-2

The solution to the equation x - 4y = 8 is an ordered pair (4,-1).

What is the solution to the equation?

A solution to an equation is a number that can be substituted for the variable to provide a true number statement.

The equation is given in the question, as follows:

x - 4y = 8

To determine the ordered pair (x,y) of the solution, substitute the value of x = 4 in the equation, and solve for y:

4 - 4y = 8

- 4y = 8 - 4

- 4y = 4

y = - 4/4

Divided by -4 into both sides of the equation, we get

y = - 1

Thus, the solution to the equation is an ordered pair (4,-1).

Part B
For how many days must the family drive to travel at least 1,300 miles? Enter your answer in the box.

days

Answers

Answer:

Part A = the middle one

Part B = 4 days

Step-by-step explanation:

1,300 / 4 = 325

325 x 4 = 1,300

Inequality to represent number of days is 325d ≥ 1300.

Number of days to travel at least 1300 is 4.

What is inequality?

An inequality is a mathematical expression in which both sides are not equal. Unlike equations, inequalities compare two values. Equal signs between are replaced by less than (or less than), greater than (or greater than), or not equals signs.

Given,

Family drives 325 miles per day

To travel at least 1300 miles

Let number of days be d

then

325d ≥ 1300

Dividing with 325 on both sides

d ≥ 1300/325

d ≥ 4

Hence, 325d ≥ 1300 is the inequality that represents number of days d to travel at least. 4 days is the least number of days.

A football team loses 3 yards on each of 4 consecutive plays. Find the total change in yards from where the team started.

Answers

Answer:

-12

Step-by-step explanation:

If you lose 3 yards for EACH of the 4 plays, than the equation is -3x4=-12

-12, If your loosing 3, it’ll be a negative number. If you loose 3 yard 4 times, it’ll be multiplying -3 • 4 and when multiplying two numbers that have different signs, the product will be negative. So, if you just multiply 3x4 it’ll equal 12. But they have different signs so it’ll be -12. :)

zach is 4 years older than twice his sister maya's age. zach is 28 years old.
which expression would you use to represent zach's age?

Answers

Answer:

Lets take:

Z - Zach

M - Maya

Now forming the equation:

Z = 2M+4

Z = 28

Solving:

2M+4 = 28

2M = 24

M = 12

Zach's age is 28; whereas Maya's age is 12.

Answer:

2m + 4 = 28

Step-by-step explanation:

Let m be Maya's age

4 years older than twice his sister Maya's age = 2m + 4 If "4 years older than twice his sister Maya's age" and "Zach is 28 years old" are equal, then this is how you'd write it: 2m + 4 = 28

The answer would be 5 1/3.

solution:

if you were to divide 16 and 3, you wouldn’t have an exact whole number to divide it by. The closet would be 5. 5x3= 15 with a remainder of 1. You take the denominator and make it 1/3. Now, you have your whole number 5 and fraction 1/3. That would mean the answer is 5 1/3

A pair of parallel lines is cut by a transversal. One of the angles formed measures 58°. Which statements about the other seven angles formed are true?
There are three more angles with the same measure.
All the other angles have the same measure.
The rest of the angles measure 122°.
Only three of the angles measure 122°.
Four of the angles measure 122°.

Answers

Answer:

There are three more angles with the same measure. A pair of corresponding angles and a pair of vertical angles.

Step-by-step explanation:

3 Answers:A) There are three more angles with the same measure. C) The rest of the angles measure 122°. E) Four of the angles measure 122°.

==========================================================

Explanation:

I recommend drawing out a diagram as shown below. Angle 1 is 58 degrees.

Angle 3 is also 58 since the two angles are congruent vertical angles.

Angle 5 is equal to angle 1 due to them being corresponding angles (this only works if the lines are parallel)

Angle 8 is congruent to angle 5, for similar reasonings with angle 3 above.

So that means we have three additional angles that are 58 degrees: angle 3, angle 5, angle 8

-------------------

The rest of the angles are 122 as the diagram shows. We have four angles that make up the rest of the angles. Angle 2 and angle 1 add to 180, so

x+y = 180

58+y = 180

y = 180-58

y = 122

And you'll find the other unknown angles fit this pattern as well. Or you could use corresponding angles and vertical angles to fill out the rest of the diagram.
