Answer:
y=(8/9)x + 4 and 2/3
Step-by-step explanation:
the slope of this line:
change in y/change in x
change in y=6-(-2)=8
change in x=-6-3=-9
change in y/change in x= 8/9
8/9 is the slope, so you plug it in for m in the standard form equation. You then use one point's x and y values to substitute for x and y in the equation, and solve for b, which is the y intercept
y=mx+b
y=(8/9)x+b
-2=(8/9)*3+b
-2=8/3+b
-4 and 2/3=b
Answer:
The number is -1/2.
Step-by-step explanation:
I am assuming they are fractions. So we have the equation:
5/2 x + 2/3 = -7/12
We multiply through by 12 to eliminate the fractions:
5/2 * 12 x + 2/3 * 12 = -7/12 * 12
30x + 8 = -7
30x = -15
x = -15/30
x = -1/2.
Answer:
You multiply it like normal numbers. But when you do, count how many numbers are behind the decimal, say there are 2 numbers behind the decimal, once you finished multiplying the numbers you would add up all the products you got and then put the first 4 numbers you wrote behind the decimal to get the final product.
Step-by-step explanation:
Say you were multiplying 14.63 and 7.74
14.63
<u> x 7.74 </u><em>Always starting from the right side of the equation</em>
.5852 <em>go to the left </em> <em>four digits and put a decimal then </em>
<em> ↑←←←← just carry the decimal down and you'll end up with </em>
10.2410 <em>the final product</em>
<u> + 102.4100 </u>
113.2362
Answer:
-3x(2y^5+5x^3-3)
Step-by-step explanation:
-6xy^5 - 15x^4 + 9x
-6xy^5-15xx^3+9x
2*3xy^5+5+3xx^3z+3*3x
Factor:
-3x(2y^5+5x^3-3)
