All the triangles are isosceles meaning that they have to sides that are equal
Answer:
1) vertex:-1
axis of symmetry:-1
y-intercept (0,-10)
x-intercepts (-3.449, 0) and (1.449, 0)
2) vertex: -1
axis of symmetry: -1
y-intercept (0,-15)
x-intercepts (3, 0) and (-5, 0)
Step-by-step explanation:
Answer:
Step-by-step explanation:
1). Let the equation of a line is,
y = mx + b
Here, m = slope of the line
b = y-intercept
From the graph attached,
Slope = =
y-intercept = -2
Equation → y =
2). Slope of the line =
y-intercept 'b' = -3
Equation → y =
3). Slope of the line =
=
y-intercept = 5
Equation → y =
4). Slope of the line =
y-intercept = 4
Equation → y =
5). Since, line is passing through origin (0, 0)
y-intercept = 0
Slope =
Equation → y = x
6). Slope of the line =
y-intercept = -4
Equation → y =
Answer:
benny paid for 5 hours.
Step-by-step explanation:
y=mx+b
M=8
B=18
Y=58
18+8x=58
subtract 18 on both sides
canceling out 18 alltogether leaving you Y as 40 then divied 40 by 8 on each side canceling out 8 and leaving you with the answer of X=5
hope this helps!!
X = 7
y = 8
As 7 is the median as it would be the middle number and the mean would now be 7 as well
