Answer:
y=3(x+8)+1 or y=3x+25
Step-by-step explanation:
Make the problem into y=mx+b (standard form) by adding 1 to both sides. Then you can simplify 3(x+8)+1 into 3x+25 by distributing and combining like terms. then graph starting from the y-intercept 25 and use the slope of 3 or 3/1 to plot the points around the y-intercept. then draw the graph. :3
110*0.6=66 blue blocks
110*0.1=11 green blocks
The answer is C, 55x-26
-11x*-5 that is 55x
7*-5=-35
9-35=-26
so the ending expression is 55x-26
Answer:
(k + 7) • (k - 6)
Step-by-step explanation:
Final result :
(k + 7) • (k - 6)
Reformatting the input :
Changes made to your input should not affect the solution:
(1): "k2" was replaced by "k^2".
Step by step solution :
Step 1 :
Trying to factor by splitting the middle term
1.1 Factoring k2+k-42
The first term is, k2 its coefficient is 1 .
The middle term is, +k its coefficient is 1 .
The last term, "the constant", is -42
Step-1 : Multiply the coefficient of the first term by the constant 1 • -42 = -42
Step-2 : Find two factors of -42 whose sum equals the coefficient of the middle term, which is 1 .
-42 + 1 = -41
-21 + 2 = -19
-14 + 3 = -11
-7 + 6 = -1
-6 + 7 = 1 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -6 and 7
k2 - 6k + 7k - 42
Step-4 : Add up the first 2 terms, pulling out like factors :
k • (k-6)
Add up the last 2 terms, pulling out common factors :
7 • (k-6)
Step-5 : Add up the four terms of step 4 :
(k+7) • (k-6)
Which is the desired factorization
Final result :
(k + 7) • (k - 6)
