Answer:
c
Step-by-step explanation:
Answer:
Infinitely many solutions.
Explanation:
In this case we gonna use ELIMINATION BY ADDITION method.For that first we are gonna eliminate the terms containing ( X ).
Equation no 1:
3x + 3y = 10
Equation no 2:
-9x - 9y = -30
Now multiply equation no 1 with (3 )
3(3x + 3y) = 3(10)
9x + 9y = 30 ( equation no 1 )
Now ADD both the equations
9x + 9y = 30
<u> -9x - 9y =-30</u>
0 = 0
Answer:
the answer is c
Step-by-step explanation:
We know that
area of lateral faces of the <span>right triangular prism=perimeter of base*height
perimeter of the base=[3+4+5]----> 12 cm
height of the prism=5 cm
so
</span>area of lateral faces of the right triangular prism=12 cm*5 cm---> 60 cm²
the answer is
60 cm²
Answer:
y=-8x-2
Step-by-step explanation:
The formula for slope is y2-y1/x2-x1. Take coordinate (0,-2), which is the y-intercept. We'll call that (y2,x2). Coordinate (8,-3) is (y1,x1). Put that into the formula you get, 0-8/-2-(-3). You get -8/1 which is negative 8. We now have the slope. Slope intercept form equation is y=mx+b. M is slope, so we put our slope in the equation and get, y=-8x+b. B is the y-intercept which is given. So we know that the equation to this line in slope-intercept form is y=-8x-2.
