Hey there :)
( 5y + 9 )( 6y - 1 )
We need to use FOIL to expand, that is
First Terms
Outer Terms
Inner Terms
Last Terms
First Outer Inner Last
( 5y )( 6y ) + ( 5y )( - 1 ) + 9 ( 6y ) + 9 ( - 1 )
30y² - 5y + 54y - 9
Combine, if any, the like-terms
30y² + 49y - 9
Answer:
Step-by-step explanation:
it is hard to know exactly by eye balling the graph I can't dissern the y intercept it might be 4.5 but it could be 4.33, but it looks for sure like the x intercept equals 6 but does it
the dots on the line are at (-2, -6) and (2, 3) so we can find the slope m
in the y = mx + b line equation b is the y intercept
m = Δy/Δx = (y1 - y2) / (x1 - x2)
= (-6 - -3) / (-2 - 2)
= -3 / -4
m = 3/4
y = 3x/4 + y intercept which i can't dissern (read directly from the
graph, but we believe y = 0 when x is six
0 = 3(6)/4 + y intercept
-18/4 = 18/4 -18/4 + y intercept
-9/2 = y intercept
-4.5 = y intercept
y = 3x/4 - 9/2 i think exact number means NO FRACTIONS but that is whole number so let me gaggle it What are exact numbers? Gaggle indicates exact numbers are integers example 3 ft in a yard 12 eggs in a dozen
y = 3x/4 - 9/2 multiple both sides by 4
4y = 3x - 36/2
4y = 3x - 18 <------------------ FINAL ANSWER
Answer: 3000cm3
To find the area you need to find the area of the triangle and multiply that by the height of the prism.
The area of the triangle is
.5*12*10 = 60
And the height is .5m = 50cm
So the area will be
60*50 = 3000
Now plug the x value into 9x + 2
Hope that helps!
Answer:
The slope is -10, and the y-intercept is 1.
Step-by-step explanation:
Assuming that the equation is y = -10x+1, the easiest way to identify slope and the y-intercept is by knowing the equation for slope-intercept (y = mx+b)
Equation for slope-intercept (y = mx+b) explained:
The equation is y = mx+b, let's break it down.
y = The line
m = The slope
b = The y-intercept
Now that we know the equation and broke it down you can identify them in your equation
Slope (m)= -10
y-intercept = 1
Conclusion: The slope is -10, and the y-intercept is 1.
