Answer:
10 units
Step-by-step explanation:
Formula to find the distance between two points 
and 
is,
d = 
Distance between two points (0, -7) and (-6, 1) will be,
d = 
= 
= 
= 10
Therefore, distance between the given points is 10 units.
Answer:
Step-by-step explanation:
Let p represent the number of pages that she read on each day after the first day.
Reggie read a 400-page book in 5 days. On the first day, he read 120 pages. The means that the remaining number of pages would be 400 - 120 = 280
The number of days remaining would be 5 - 1 = 4
Since she read the same number of pages on each day after the first day, then
4p = 280
p = 280/4 = 70 pages
Answer:y = 2x + 4
Explanation:
1) The slope - intercept form is of the kind y = mx + b, where m is the slope and b is the y-intercept.
2) Given two points you can find the slope (using the two points) and then the equation using one of the points.
3) slope = m = Δy / Δx
points given (3,10) , (0,4)
m = [y2 - y1] / [x2 - x1] = [10 - 4] / [3 - 0] = 6 / 3 = 2
4) equation
y - y2
-------- = m
x - x2
y - 4
---------- = 2
x - 0
=> y - 4 = 2 (x - 0)
y - 4 = 2x
y = 2x + 4
Answer:
Step-by-step explanation:
1) ΔCPD & ΔEPF
∠CPD = ∠EPF { Vertically opposite angles}
∠CDP = ∠PFE {CD║EF, FD is transversal, Alternate interior angles are equal}
ΔCPD ≈ΔEPF {AA criteria for similarity }
Cross multiply
EF * 15 = 27 * 7.5
EF = 27 * 0.5
EF = 13.5 cm
ii) EF // AB, so Triangles ACB & ECF are similar triangles
AC = 37.5 cm
Answer:
That guy is correct a because its both greater than and equal to 8
