(trigonometry question)
-I'll give branliest as a reward-

Answer:

3. Since it asked us to write question 3 in the from y=mx + c

m is the gradient

c is the intercept on y axis or where the line enters or cuts the y axis. This can be seen from the diagram. The line cuts the y axis at "9". (Check the diagram for this).

Now to find m.

Pick points on the line

Say (1,6) and (2,3)

Gradient = m = y2 - y1/(X2 - X1)

x1 = 1

y1 =6

x2 = 2

y2 = 3

Substituting into that formula

m = 3 - 6/2 - 1

m= -3/1

m= -3.

Since we've gotten what we need

y=mx + c

Y= -3x + 9.

4. 4x + 2y = 12

Rearranging by making y subject to suit the eqn...y=mx + c

you have

m is the gradient and c is the intercept.

2y = -4x + 12

Divide through by 2

y= -2x + 6

y=mx + c

By comparing...

m==gradient = -2

c== Intercept = 6

5). Doing the same thing we did above

-6x + 3y =21

Making y subject

3y = 6x + 21

Divide through by 3

y= 2x + 7

y=mx + c

m==gradient =2

c==Intercept =7.

Hope this helps.

Have a great day!

Answer:

3x + 132⁰ = 180⁰

3x = 48

x = 16⁰

Answer:

3x + 132 = 180°

Step-by-step explanation:

There are 3 x's and all of them need to be added in order to find the angle. Looking at the overall sum of the angle, a strait line would = 180°. Also, remember to use PEMDAS rules, before writing down your equation.

Answer:

8 1/2

Step-by-step explanation:

I converted to decimals to make it easier :)

9.75 - 2.2 + 0.5

This is equal to 8.05, which is equal to 8 and 5/100, or 8 and 1/20

Answer:

6/23

Step-by-step explanation:

spinner was spun 23 times, 5 times it landed on 5 and once on 7, so:

P(5 or 7) = 5/23 + 1/23 which is 6/23

Answer: 6/23

Step-by-step explanation:

Experimental probability uses the numbers from the experiment.

The number of 5s and 7s total is 6.

Total spins is 23.

6/23

Answer:

f(x)=x+4

g(x)=x+10

g(x)=f(x+k)

x+10=x+k+4

x-x+10-4=k

6=k

k=6

Step-by-step explanation:

angle 13 is supplementary to angle 16 bcoz of the property of linear pair

Answer:

C)

Step-by-step explanation:

First, multiply the 2 factors that add up to 8.

1/3 x 2. Since this equation does not have one x but 2 (x and y), we will not subtract or divide any sides.

Divide and multiply 2 by 8 and 1/3. Then, we solve for y.  

y = 2/3x - 4

Hope this helps!

Answer:

D

Step-by-step explanation:

First, plot the points they gave you onto a graph (shown in the attached image). The slope is the rise (units up or down from a given point) over the run (units left or right from a given point).

So the slope is 6/4 because to get from the red point to the blue point, you rise 6, and run 4. And from blue to red you rise (remember rise goes up or down) 6 and run 4. 6/4 can be simplified to 3/2 so D is your answer :)

Answer:

a = 3/4

Step-by-step explanation:

2/3a - 1/6 = 1/3​

Multiply each side by 6 to clear the fractions

6*(2/3a - 1/6) = 6*1/3​

Distribute

4a - 1 = 2

Add 1 to each side

4a -1+1 = 2+1

4a = 3

Divide each side by 4

4a/4 = 3/4

a = 3/4

Answer:

a= 1/3

Step-by-step explanation:

-1/4

This will remain its absolute value

Answer:

absolute value is the oppistie of the number so if it is positive is will turn negative so i think the answer is C

Answer:

a) 60°

b) 60°

c) 30°

Step-by-step explanation:

Get 60 by subtracting 30 from 90 because the angle is a right angle. Since b is identical to a and also is a right triangle, it will also be 60. Get c as 30 by looking at its vertical angle across from it.

C 10ft

Step-by-step explanation:

The diameter of a circle is always double the radius of a circle.

Answer:

C

Step-by-step explanation:

1. π ≈ 3.1415. π + 10 ≈ 13.1415.

2. Find the square root of 20. It is about 4.4721. 4.4721 + 1/2 (or .5) = 4.9721

3. The square root of 100 is 10.

4. Order them.

5. It is most obvious that the answer to [tex]\sqrt{20\\}[/tex] + 1/2 is first. The square root of 100 is ten, so that goes second because pi + 10 is greater than 10. (pi + 10 goes last)

6. [tex]\sqrt{12} + 1/2, \sqrt{100}, \pi + 10[/tex]

Answer:

isosceles triangle

Step-by-step explanation:

Answer:

[tex]6\frac{1}{2}[/tex]

Step-by-step explanation:

When given the following problem:

[tex]7\frac{1}{7}-\frac{9}{14}[/tex]

Convert the first mixed number to an improper fraction. This can be done by multiplying the "number" part of the mixed number by the denominator of the fraction, the number under the fraction bar. Then add the result to the numerator.

[tex]\frac{50}{7}-\frac{9}{14}[/tex]

To perform this operation, one must ensure that both denominators have the same value. Multiply the numerator and denominator for the first fraction by (2), so that the denominators of both fractions is (14),

[tex]\frac{100}{14}-\frac{9}{14}[/tex]

Perform the operation, subtract one numerator from the other, leave the denominators the same,

[tex]\frac{91}{14}[/tex]

Simplify, divide the numerator by (14) (the denominator), write the whole part as the "number" part of the mixed number. Then write the remainder on top of the fraction bar.

[tex]6\frac{7}{14}[/tex]

Reduce, divide the numerator and denominator by a common fraction,

[tex]6\frac{1}{2}[/tex]
