Answer:
7x^2 −12x−10
Step-by-step explanation:
((5x2 - 8x) + 1) + (2x2 - 4x - 11)
Factoring 7x2-12x-10
The first term is, 7x2 its coefficient is 7 .
The middle term is, -12x its coefficient is -12 .
The last term, "the constant", is -10
Step-1 : Multiply the coefficient of the first term by the constant 7 • -10 = -70
Step-2 : Find two factors of -70 whose sum equals the coefficient of the middle term, which is -12 .
-70 + 1 = -69
-35 + 2 = -33
-14 + 5 = -9
-10 + 7 = -3
-7 + 10 = 3
-5 + 14 = 9
-2 + 35 = 33
-1 + 70 = 69
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Answer:
5/3
Step-by-step explanation:
3y = 5x - 6
y = 5/3x - g
using y = mx + b
gradient = m
gradient = 5/3
Answer:
Step-by-step explanation:
Have to assume that you're supposed to "solve y = -2x + 8" for some value of x. If that value happens to be -2, then y = -2x + 8 becomes
y = -2(-2) + 8 = 12.
Check to ensure that you have copied down the entire problem, including the instructions.
To find the experimental probability, you will add the outcomes that resulted in even number and make that a ratio to the total number of outcomes.
<u>(12 + 14 + 18)</u>
(13 + 12 + 12 +14 + 11 + 18)
44/80 = 0.55
0.55 = 55%
The answer is choice D.
Answer:
y = -4
Step-by-step explanation:
This is because any point on that line would have a y coordinate of -4 → e.g. (6, -4), (-2, -4), and it intercepts the y axis at -4.
Hope this helps!
