Which equation represents the number of points in the problem below?

Mathematics
1 answer:
Akimi4 [234]3 years ago
6 0

Answer:

Step-by-step explanation:

Let the number of MC questions = x

Let the number of SA questions = y

x + y = 15

2x + 5y = 60

Multiply the top equation by 2

2x + 2y = 30

Put this underneath the second equation and subtract

2x + 5y = 60

2x + 2y = 30           Subtract

 3y = 30

   y = 10                  Subtract

2y = 20

y = 10

x + y = 15

x + 10 = 15

x = 5

HELP Apex need fast please!!
Burka [1]

Answer:

35 degrees

Step-by-step explanation:

The angles in a triangle and a straight line add up to 180 degrees.

So adding the angles together:

BCD + BCA = 180

75 + BCA = 180

BCA = 115

Then,

BCA + BAC + ABC = 180

115 + 40 + ABC = 180

Therefore,

ABC = 35 degrees

kipiarov [429]

y=2

\lbrack0,1)\text{ }\cup\text{ (3,4}\rbrack

\begin{gathered} so,\text{ the function is negative in } \\ (1,3) \end{gathered}

Explanation

Step 1

The y -intercept of a graph is the point where the graph crosses the y -axis.

so , let's check the graph

therefore, the y-intercept is 2

Step 2

The positive regions of a function are those intervals where the function is above the x-axis. It is where the y-values are positive (not zero)

hence, the function is potive in ( in x axis)

\lbrack0,1)\text{ }\cup\text{ (3,4}\rbrack

Step 3

negative region

The negative regions of a function are those intervals where the function is below the x-axis. It is where the y-values are negative (not zero).

\begin{gathered} so,\text{ the function is negative in } \\ (1,3) \end{gathered}
