X=9. x=-15. you also have to turn the 24 into a negative and solve the equation
Answer:
y= -x+0: has a negative slope.
y=x: has a negative slope.
y=-4: has a slope of zero, a straight line from left to right, passing thru 4
Answer:
C. 
Step-by-step explanation:
The formula for surface area is
LA + 2B
LA indicated Lateral Area and can be found multiplying perimeter of base by the height.
7 + 7 + 14 + 14 = 42 * 7 = 294
Multiply the LA from above with the area of base times 2.
98 * 2 = 196
294 + 196 = 490, so the surface area of the rectangular prism is 490 units.
C = 3
You isolate the variable by dividing each side by factors that don’t contain the variable
