Answer:
If a is greater than 0 that means the variable has to be a number above 0
Step-by-step explanation:
If you have a right triangle, you can use the Pythagorean theorem, which is a²+b²=c². (c is the longest side or the hypotenuse)
You plug in the shorter sides for a and b, then you square root the answer.
A 14m, 20m, 25m
14² + 20² = 25²
196 + 400 = 625
596 = 625 X
B 10cm, 6cm, 8cm
6²+8²=10²
36+64=100
100=100 So your answer is B
Let x be the smaller number and y the larger:
As the numbers are consecutive y - x = 1
And 3y + x = 31 (3 times the large added to the smaller)
From the first equation y = x + 1
By substituting:
3(x + 1) + x = 31
3x + 3 + x = 31
4x = 28
x = 7
y = x + 1
y = 7 + 1 = 8
Your equation is already in one of the standard form. Specifically, the slope intercept form.
y=mx + b.
m is the slope, b is the intercept.
Start with the intercept y= 2, the point (0,2).
A slope of 3 would give you (1,5) as a second point for your line.
Get a ruler and draw a line through the two points.
x=15
multiply each side by 3/2
x becomes isolated, 10*1.5=15
x=15
