Answer: i think the answer is 0, -3
Step-by-step explanation:
Answer:
D)
Step-by-step explanation:
Since we see the whole angle is 90° and it's split into two smaller angles, 7x° and 11x°, then we can conclude that 7x°+11x°=90°
*And x=5
Answer:
4,5

P= 2l+2w
P-2l= 2w
1/2P -l= w
Rearrange into standard form.
w= 1/2P -l
Answer & Step-by-step explanation:
Slope-intercept form:
m is the slope and b is the y-intercept. Insert the given slope:
To find the y-intercept, take the given coordinate point and insert:
Solve for b:
Simplify multiplication:
Subtract 45 from both sides:
The y-intercept is -50. Insert:
Use the slope formula for when you have two points:
The slope is the change in the y-axis over the change in the x-axis, or rise over run. Insert the points:
The slope is . Insert:
Now follow the steps from the last problem to find the y-intercept. Choose a point and insert into the equation:
Solve for b:
Simplify multiplication:
Re-insert:
Subtract b from both sides:
Subtract 4 from both sides:
Simplify subtraction:
Re-insert:
Divide both sides by -1 to make the variable positive (can be seen as -1b):
The y-intercept is .
Write the equation:
