Answer:

\boxed{ \bold{ \huge{ \boxed{ \bold{ \sf{x = 2}}}}}}

Step-by-step explanation:

Given, h(x) = 13

To find : value of x

\sf{h(x) = 9 +  {x}^{2} }

\longrightarrow{ \sf{13 = 9 +  {x}^{2} }}

Swap the sides of equation

\longrightarrow{ \sf{9 +  {x}^{2}  = 13}}

Move 9 to right hand side and change it's sign

\longrightarrow{ \sf{ {x}^{2}  = 13 - 9}}

Subtract 9 from 13

\longrightarrow{ \sf{ {x}^{2}  = 4}}

\longrightarrow{ \sf{ \sqrt{ {x}^{2} } =  \sqrt{4}  }}

\longrightarrow{ \sf{x = \: \sqrt{ {2}^{{2}} }}}

\longrightarrow{ \sf{x = 2}}

Hope I helped!

Best regards!

Mr. Gutierrez had $100 to purchase candy for his students that completed their work. He
Sidana [21]

Answer:

$21.50

Step-by-step explanation:

Mr. Gutierrez had $100 to purchase candy for his students that completed their work.

He bought 8 bags of jolly ranchers

Each bag of jolly ranchers cost $3.25.

Hence, the cost of 8 bags of jolly ranchers = 8 × $3.25

= $26

He also bought 25 bags of assorted chocolate and each bag of assorted chocolate cost $2.10.

Hence, the cost of 25 bags of assorted chocolates = 25 × $2.10

= $52.5

Therefore, the amount of money Mr. Gutierrez has left over after these purchases is calculated as:

Total amount - Sum of ( Cost of 8 bags of jolly ranchers + 25 bags of assorted chocolates)

= $100 - ( $26 + $52.5)

= $100 - $78.50

= $21.50

Determine which of the following equations, when graphed, intersect at the point (4, 0). Select all that apply. x - y = 4 -x - y
Elza [17]

Answer: only (x-y=4) and (x+y=4).


Step-by-step explanation:

Notice target point has y=0, so all terms with y are zero. Then all 6 equations reduce to m x = k, for various m and k. So calculate 4×m and compare to k six times.


x - y = 4 4=4 yes

-x - y = 4 -4=4 no

2x - y = 7 8=7 no

x + y = 4 4=4 yes

2x + y = 7 8=7 no

2x + y = -7 8=-7 no.

Alik [6]

Answer:

60 ; - 40 ; 22 ; - 11

Step-by-step explanation:

Given that:

Number of questions = 20

Rules :

Every correct answer scores 3 points.

Each incorrect answer loses 2 points.

A question not answered scores 0 points.

It is possible to finish the quiz with a negative score.

a)

Maximum score : answering all questions correctly :

(3 points * 20 questions)

= 3 * 20

= 60 points

b)

Minimum score is obtainable by answering all questions incorrectly ;

(-2 points * 20)

= - 40 points

c)

10 correct answers = (3 * 10) = 30 points

(14 - 10) = 4 incorrect answers = (-2 * 4) = - 8 points

Net total = 30 + (-8) = 30 - 8 = 22 points

d) Another student answers 18 questions,

5 are correct. How many points does she score?

5 correct answers = (5 * 3) = 15 points

(18 - 5) incorrect answers = (13 * - 2) = - 26 points

Net total = 15 + (-26) = - 11 points
