Answer:
10
Step-by-step explanation:
give brainliest please!
hope this helps :)
so these two angles add up to 180 degrees
7x -3 + 12x -7 = 180
7x+12x=180+7+3
19x=190
x=10
to check if this is true we can input 10 for x in each side.
7(10)-3 = 67
12(10)-7 = 113
113+67 = 180
Website 1 : y = 1.50x + 30
website 2 : y = 2x + 0...or just y = 2x
=======================
y = 4x - 4
y = -4x + 4
4x - 4 = -4x + 4
4x + 4x = 4 + 4
8x = 8
x = 1
y = 4x - 4
y = 4(1) - 4
y = 4 - 4
y = 0
so this is a consistent system because it has one solution (1,0)
Answer:
<u>First blank:</u> 2. Extrapolation
<u>Second blank:</u> 2. 69
Step-by-step explanation:
Extrapolation should be used because the point (x, y) is further than the points included in the table, that is, the x-coordinate will be greater than 12 when y = $0
Replacing y = 0 into the equation, we get:
0 = -115.9x + 8,007.30
115.9x = 8,007.30
x = 8,007.30/115.9
x = 69
Step-by-step explanation:
f(x) = 2x - 1
f(10) = 2(10) - 1
= 20 - 1 = 19
Answer: A8 3b c730
Step-by-step explanation: The number A8 is a two-digit number with tens digit A and units (ones) digit 8. Similarly, 3B is a two-digit number with tens digit 3 and units digit B. When A8 is multiplied by 3B, the result is the four-digit number C730.
