y = mx + b
y = 2x + 1
y - y₁ = m(x - x₁)
y - 4 = 2(x - 5)
y - 4 = 2(x) - 2(5)
y - 4 = 2x - 10
+ 4 + 4
y = 2x - 6
Answer:
Question 13: x = 47°
Question 14: x = 67°
Step-by-step explanation:
Question 13:
add up all the known factors meaning 16, 27 and 90°, then subtract 180 from what you got from adding known factors
Question 14:
out out of all numbers meaning 19, 4 and 90°, then subtract 180 from what you got from adding all known factors
-4 = 3x + 6y
6y = -3x - 4
y = -1/2x - 2/3.....slope here is -1/2. A parallel line will have the same slope
ax - 8y = 12
-8y = -ax + 12
y = (-a/-8)x + 12......so a would have to be -4 because -(-4) / -8 = -4/8 = -1/2
ur answer is : a = -4
The area of Victoria's poster is twice the area of Krystal's poster.
<h3>How compare the areas of two similar posters</h3>
The two areas are shown in the image attached below. Each poster represents a rectangle and the ratio between the two areas (
), no unit, is defined by the following formula:
(1)
Where:
- Width of Victoria's poster, in feet.
- Height of Victoria's poster, in feet.
- Width of Krystal's poster, in feet.
- Height of Krystal's poster, in feet.
If we know that 
, 
, 
and 
, then the ratio between the two areas is:
The area of Victoria's poster is twice the area of Krystal's poster.

Answer:
11
Step-by-step explanation:
1+red/3=4/1 so 1+red=12 so red=11. we should add 11 red counters
