Volume of prism = area of base * height
= area of triangle * height
(in this case triangle)
Volume = ( 0.5*13*13)*7
= (84.5)*7
= 591.5
answer is C
Answer:253.33...
Step-by-step explanation:
I = PRT
21 = 200 * 0.035 * T
21 = 7T
3 years = T
Answer:
$71.61
Step-by-step explanation:
66/22 = 3
3 · $1.87 = $5.61
$66 + $5.61 = $71.61
OR
$23.87 · 3 = $71.61
Sorry if this is wrong!
So, both equations are essentially linear equations.
Linear equations are written in the format
y = mx+b, where
m represents the
slope/slope intercept and
b represents the
y-intercept.
---------------------------------------------------------------------------------------------------------------
Part Athe slope and y-intercept
y = mx +b
m - the slope; b- y-intercept
therefore;
y = 6x - 4
m = 6; b = -4y = 5x - 3
m = 5; b = -3The coordinates of the point where the lines are crossed are the solution to the system of linear equations.
How to graph the lines:
y = 6x - 4
y-intercept (0; -4)
for x = 1 ⇒ y = 6 · 1 - 4 = 6 - 4 = 2 ⇒ (1; 2)
y = 5x - 3
y-intercept (0; -3)
for x=1 ⇒ y = 5 · 1 - 3 = 5 - 3 = 2 ⇒ (1; 2)
***look at the img for graph reference***Part B:
x = 1; y = 2
