Answer:

88°

Step-by-step explanation:

The triangle is an isosceles triangle, so two of the angles are both 46°. We also know that the sum of all the angles in any triangle is 180°, so we can set up the following equation:

46° + 46° + e = 180°

Solving this gets e = 88°.

Step 1) Draw a dashed line through the points (0,6) and (4,7). These two points are on the line y = (1/4)x+6. To find those points, you plug in x = 0 to get y = 6. Similarly, plug in x = 4 to get y = 7. The dashed line indicates that none of the points on this line are part of the solution set.

Step 2) Draw a dashed line through (0,-1) and (1,1). These two points are on the line y = 2x-1. They are found in a similar fashion as done in step 1. 

Step 3) Shade the region that is above both dashed lines. We shade above because of the "greater than" sign. This is shown in the attached image I am providing below. The red shaded region represents all of the possible points that are the solution set. Once again, any point on the dashed line is not in the solution set.

Solve the simultaneous equations. You must show all your working to find x and y. 1/2x -3y = 9 5x y + y = 28
dedylja [7]

Answer:

\huge\boxed{x = 6 , y = -2}

Step-by-step explanation:

\sf \frac{1}{2} x - 3y = 9-----------(1)\\5x + y = 28 ----------(2)

Taking equation (1)

\sf \frac{1}{2} x -3 y=9

Multiplying both sides by 2

\sf x-6y = 18

Adding 6y to both sides

\sf x = 18+6y

Putting this in (2)

5(18+6y) + y = 28

5(18+6y) + y = 28

90 + 30y+y = 28

31y+90-28 = 0

31 y + 62 = 0

31y = -62

Dividing both sides by 31

y = -2

Now,

x = 18 + 6y

x = 18+6(-2)

x = 18-12

x = 6

Which angle is an x-intercept for the function y = cos(1)<br> A.0<br> B.2<br> C. £<br> D. 2£
noname [10]

Answer: C. \pi

=======================================================

Explanation:

The x intercept always occurs when y = 0.

Use the unit circle to determine that \cos(\theta) = 0 when \theta = \frac{\pi}{2} \text{ and } \theta = \frac{3\pi}{2}

So if x = \pi, then we have

y = \cos\left(\frac{1}{2}x\right)\\\\y = \cos\left(\frac{x}{2}\right)\\\\y = \cos\left(\frac{\pi}{2}\right)\\\\y = 0\\\\

which shows us that (\pi, 0) is the location of one of the infinitely many x intercepts for this function.
