Step-by-step explanation:

Answer 2

Answer:

x = 34°

Step-by-step explanation:

(x + 7) + (63° + (2x + 8) = 180°

combine like terms:

3x + 78° = 180°

subtract 78 from each side of the equation:

3x = 102°

divide both sides by 3:

x = 34°

(1a) There is a closed carton of eggs in Mai's refrigerator. The carton contains e eggs and it can hold 12 eggs. What does the inequality e<12 mean in this context?

Answers

Answer:

e<12 mean in this context means that the number of eggs in the carton is not up to 12

Step-by-step explanation:

The number of eggs in the carton = 12

The capacity of egg carton is depicted as e

Hence, the inequality e<12 in this context means that :

The number of eggs in the carton is less than the capacity of the egg carton

Thus we can conclude that the number of eggs in the carton is not up to 12, which is the number of eggs the carton can hold.

Write in Slope-Intercept Form an equation of the line that passes through the given points.
(-3,1) and (3,9)

Answers

Answer:

do u hate people like that to who tell you to downlaod viruses

Step-by-step explanation:

3. Choose the equation of the line parallel to the line 5 = -10x - 5y that passes through the point (-2,5). A y=-2x + 1 C y=x-5 By=-12x + 5 D y = 5x + 11​

Answers

Answer:

y = -2x + 1

Step-by-step explanation:

The equation is in standard form, first, we need to convert it to slope-intercept form.

5 = -10x - 5y

5 + 10x = -5y

Divide both sides by -5 to isolate y variable.

y = -2x - 1

If the line is parallel, the slope remains the same.

To find the y-intercept, you need to plug the values of x and y into the equation, which is y = 2x + b

5 = -2(-2) + b

5 = 4 + b

1 = b

The equation is -2x + 1

Answers

Answer:

D

Step-by-step explanation:

let's rewrite this

x + y = 11                  - equation 1

   - x = - y - 9           - equation 2

solve the first equation for x

x + y = 11            (add -y to both sides to get x by itself)

     x = -y + 11           - equation 3

now substitute -y + 11 for x in the second equation

 y - 11 = - y - 9        (2 negative signs next to each other equals positive)

2y - 11 = -9              (add y to both sides)

      2y = 2               (add 11 to both sides)

        y = 1                (divide both sides by 2)

now substitute y = 1 into equation 3

x = -1 + 11

x = 10

therefore, x = 10 and y = 1. in coordinates, x goes before y

therefore, the coordinates are (10, 1)

therefore the answer is D

good luck my friend! hope this helped a lot! also, i found a website if you don't fully understand this, its called MathPapa, i didn't use it to work this out so my working might be different but it definitely helps me sometimes. for an equation like this, type it likes this: x+y=11; -x=-y-9

The number of students that  should the teacher predict will participate in the program is option C. 108 students

Calculation of the number of students:

Since 15% of the students would be interested in a summer creative writing program and there are 720 students

So, the number of students should be

= 15% of 720

= 108

Therefore, The number of students that  should the teacher predict will participate in the program is option C. 108 students

Nalani says the expression 9+7r cannot be factored using the GCF. Is she ​correct? Explain why or why not

Answers

Answer:

Nalani is correct.

Step-by-step explanation:

Given - Nalani says the expression 9+7r cannot be factored using the GCF.

To find - Is she ​correct? Explain why or why not.

Proof -

GCF - Greater Common factor

Given that, the expression is - 9 + 7r

As

HCF(9, 7) = 1

So , we can not factor the expression.

i.e. there does not exist any number who is a multiple of 9 and 7 both.

So,

Nalani is correct.

Example -

Let the expression be 24 + 18x

HCF(24, 18) = 6

So,

24 + 18x = 6(4 + 3x)
