Answer:
3 for problem
Step-by-step explanation:
Answer:
y = -2
Step-by-step explanation:
The line x = -3 is a vertical one; the slope of a line perpendicular to x = -3 is zero (0). Recall that the slope of a vertical line is undefined and that of a line perpendicular to a vertical line is 0.
Then, to write the equation of the perpendicular line, we borrow the '-2' from (-9, -2) and write y = -2. This line does indeed pass through (-9, -2) and every other point whose y-component is -2.
Answer:
p=7
∠BRG=49
Step-by-step explanation:
∠BRG and ∠YRG are on a straight line together. Therefore, they are supplementary and add to 180 degrees.
∠BRG+∠YRG=180
We know that ∠BRG is 7p and ∠YRG is 131 degrees. Substitute 7p in for ∠BRG and 131 for ∠YRG.
7p+131=180
We want to find out what p is. In order to do that, we have to get p by itself. First, subtract 131 from both sides.
7p+131-131=180-131
7p=49
Next, divide both sides by 7.
7p/7=49/7
p=49/7
p=7
Now, we have to find what ∠BRG is.
∠BRG=7p
We know that p=7, so substitute p in for 7
∠BRG=7*7
∠BRG=49
So, p=7 and ∠BRG=49
Answer:
Step-by-step explanation:
−2/9x+2.7=4
subtract 2.7 from both sides
-2.9x = 1.3
divide -2.9 from both sides
x= -.4482 or x= -.45
