A, B and D are your answers according to e2020
First, we find the equation of the line...
(1,3),(-3,7)
slope = (7 - 3) / (-3 - 1) = 4/-4 = -1
y = mx + b
slope(m) = -1
use either of ur points.... (1,3)...x = 1 and y = 3
now sub into the formula and find b, the y int
3 = -1(1) + b
3 = -1 + b
3 + 1 = b
4 = b
so the equation for this line is : y = -1x + 4 which is usually written as :
y = -x + 4
Now...to find where the line crosses the x axis (or the x intercept)...we sub in 0 for y and solve for x
y = -x + 4
0 = -x + 4
x = 4... so ur x intercept (where the line crosses the x axis) is : (4,0)
Answer:
h = 3 cm
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = 
bh ( b is the base and h the height )
Here A = 7 
= 
← expressed as an improper fraction
and b = 5 
= 
, thus
× × h = , that is
h =
Multiply both sides by 8 to clear the fractions
21h = 63 ( divide both sides by 21 )
h = 3
Answer: is A
Step-by-step explanation:
i just took the test
Answer:
12 cm
Step-by-step explanation:
20² = length² + 16²
length² = 400 - 256 = 144
length = 12
Check
20² - 16² = 12
Hopefully I'm right!!
