Answer
87 measures an acute angle
Step-by-step explanation:
Step-by-step explanation:
step 1. what is the question? maybe the question is what is the value of x in the diagram. okay.
step 2. interior angles of a triangle add up to 180°
step 3. the 3 angles inside the triangle are 10x + 8, 13 + 5x, and (180 - 126)
step 4. (10x + 8) + (13 + 5x) + 54 = 180
step 5. 15x + 21 = 126
step 6. 15x = 105
step 7. x = 7.
Answer:
Pairs (2,4), (4,8) and (5,10) makes the equation y=2x true
Step-by-step explanation:
By using the equation y=2x, eval the following points (gathered from the attached picture)
1. (2,4) which leaves us 4=2*2
2. (4,8) which leaves us 8=4*2
3. (5,10) which leaves us 10=5*2
All points from this graph satisfies the equation y=2x
The slope is given as m = 7m=7 and the yy-intercept as b = - \,4b=−4. Substituting into the slope-intercept formula y = mx + by=mx+b, we have
since m=7 and b=-4, we can substitute that into the slope-intercept form of a line to get y=mx+b → y=7x-4
The slope is positive thus the line is increasing or rising from left to right, but passing through the yy-axis at point \left( {0, - \,4} \right)(0,−4).
Step-by-step explanation:
The answer is 2, y=-3x-5
Slope-intercept form is y=mx+b, where m is slope and b is the y-intercept.
So if m=-3 and b=-5, the equation is y = -3x -5
