Step-by-step explanation:

Mr. Martin is giving a math test next period. The test, which is worth 100 points, has 29 problems. Each problem is
worth either 5 points or 2 points. Write a system of equations that can be used to find how many problems of each
point value are on the test.
Let x be the number of questions worth 5 points and let y be the number of questions worth 2 points.
O x + y = 29, 5x + 2y = 100
x + y = 100, 5x + 2y = 29
5x + y = 29, 2y + x = 100
O 2x + y = 100, 5y + x = 29

Answers

Answer:

Step-by-step explanation:

From the conditions given, the total number of the problems should be 29. This means that the sum of x and y should be 29. With this and the point-system, the best system of equation that is useful for this problem is,

                                     x + y = 29

                                     5x + 2y = 100

The answer is the second choice.  

Answer:

The correct answer is A

A. x + y = 29, 5x + 2y = 100

5. Write equations in slope-intercept form for three different lines that intersect at (–2, 3). Show your work.

Answers

Answer:

Equations in slope-intercept form for three different lines that intersect at (–2, 3) are y=-x+1  ,  y=3  and y=x+5

Step-by-step explanation:

General equation of slope intercept form : [tex]y-y_1=m(x-x_1)[/tex]

We are supposed to find equations in slope-intercept form for three different lines that intersect at (–2, 3).

[tex](x_1,y_1)=(-2,3)[/tex]

Substitute the value in the general equation

y-3=m(x+2)

Now substitute any 3 values of m

At m = -1

[tex]\Rightarrow y-3=-x-2 \\\Rightarrow y=-x+1[/tex]

At m =0

[tex]\Rightarrow y-3=0 \\\Rightarrow y=3[/tex]

At m =1

[tex]\Rightarrow y-3=x+2 \\\Rightarrow y=x+5[/tex]

They all intersect at the given point.

So, equations in slope-intercept form for three different lines that intersect at (–2, 3) are y=-x+1  ,  y=3  and y=x+5

Answer:

y-3=-x-2

   y=-x+1

y-3=0

 y=3

y-3=x+2

y=x+5

Solve for X please help

Answers

Answer:

71 degrees

Step-by-step explanation:

Sum of three angles of triangle=180

Let's find the third angle

73+36=109

180-109=71

Vertical angles are congruent so x= angle 3

So x is 71 degrees

Answer:

79 degrees

Step-by-step explanation:

Remember: Triangles always add up to 180 degrees.

x is vertical to the missing angle in the triangle, which means x and the missing angle are equal.

to find the missing angle in the triangle, you add up the other angle measurements and subtract from 180.

36+73=109

180-109=71

The third mising angle is 71 degrees.

this means x is also 71.

What are trigonometric functions?

In mathematics, trigonometric functions are real functions that relate an angle of a right-angled triangle to ratios of two side lengths. The six trigonometric functions are Sine, Cosine, Tangent, Secant, Cosecant, and Cotangent.

Given here Sin 45° and Sin 45 degrees is the value of sine trigonometric function for an angle equal to 45 degrees. The value of sin 45° is 1/√2 or 0.7071 (approx).

Hence, the value of Sin 45° is 1/√2
