Answer:

y = 55

Step-by-step explanation:

The sum of the angles of a triangle are 180

40 + y+30 + y = 180

Combine like terms

70 +2y = 180

Subtract 70 from each side

2y = 180-70

2y = 110

Divide each side by 2

2y/2 = 110/2

y = 55

I need to know which points go wj ere please
g100num [7]
The equations give you information as to where to plot points.

For y = -x + 1, you know the slope is -1, and the line intersects the y-axis at (0, 1). The y-axis is the vertical line; to plot (0, 1), find 1 on the vertical line and mark it. Now, the slope is -1; that means the line will slope downwards. To plot more points, count 1 unit down from (0, 1) and 1 unit to the right. You should end up at (1, 0).Connect those and you have a line.

For y = -2x + 4, the slope is -2 (so it will also slope downwards), and the y-intercept is 4. Find (0, 4) and plot it. The -2 tells you to count 2 units down (instead of 1 like we did for the last equation) and 1 over. That is the second line.

I hope this helps.

21$ with 8.5% tax.How much
PilotLPTM [1.2K]
First find the amount of tax by multiplying 21 × 8.5%.

.085 × 21 = 1.785 = 1.79 (rounded)

Now add the tax back into the price...

21 + 1.79 = $22.79

Can someone help me with this diagram problem?
mart [117]

Answer: the diagonal is 10 units

Step-by-step explanation:

The rectangle has 2 parallel and equal sides. Each of the 4 angles in a rectangle is 90°. Therefore, the diagonal of the rectangle divides it into 2 equal right angle triangles and the diagonal represents the hypotenuse of both right triangles.

To determine the length of the diagonal of the rectangle, d, , we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

Therefore

d² = 5² + (5√3)²

d² = 25 + 25×3 = 100

d = √100

d = 10 units
