Answer:

x=(5+√73)/2 or x=(5-√73)/2

Step-by-step explanation:

a=1 b=-5 c=-12

x= (-b+/-√b^2-4ac)/2a

x= (-(-5)+/-√(5)^2-4(1)(-12))/2(1)

x= (5+/-√25-4(-12))/2

x= (5+/-√25+48)/2

x= (5+/-√73)/2

x=(5+√73)/2 or x=(5-√73)/2

√: This symbol represents the square root if you get confused.

Answer:

x = 4, y = 2

Step-by-step explanation:

x - 6y = - 8 is the same as x = 6y - 8

sub that into x + 6y = 16 :

6y - 8 + 6y = 16

12y = 16 + 8

y = 2

sub that into x = 6y - 8:

x = 12 - 8 = 4

-10 irá el -9

Answer:

100

Step-by-step explanation:

3+7=10

-90+180=90

10+90=100

Answer:

135 degrees

Step-by-step explanation:

(8x-7)+(12x+57)=180

combine like terms

20x+50 = 180

subtract 50 on both sides

20x = 130

divide by 20

x = 130/20

x = 13/2

x = 6.5

cpq = 12x+57

cpq = 78 + 57

cpq = 135

Answer: Mr Brust snored a total of 19,840 times last summer

Step-by-step explanation:

Mr Brust snores in the ratio of 1 nap : 320 snores or 1 nap = 320 snores

Given that he took a  nap everyday,  last summer We have that  .

For the month of July,

he had 31 naps( 31 days are in July)

Number of snores he made =31 x 320=9,920 snores

For the month of August

he also took 31 naps ( 31 days are in AugusT)

Number of snores he made = 31 x 320=9,920 snores

Therefore  Mr Brust snored a total of 9,920+ 9,920 =19,840 times

▶️ 3⁴ = 81

The value of 3⁴ is 81..

Answer:

They both equal 23 so it’s a true statement

Step-by-step explanation:

h(x) = x3 + x and g(x)

=

h(2) = 2^3 + 2

= 8 + 2

= 10

g(h(2))

= g(10)

= 2*10 + 3

= 20 + 3

= 23

2x +3, then g(h(2))

=

h(2) = 2^3 + 2 = 8+2 = 10

Now we will substitute into g(h(2)

g(h(2)) = g(10)

Now we will substitute into g(x).

g(10) = 2*10 + 3 = 23

g(h(2)) = 23
