Answer:
2(x-5)(x+4)
Step-by-step explanation:
2x^2 − 2x − 40
Factor out a 2
2(x^2 -x -20)
What 2 numbers multiply to -20 and add to -1
-5*4 = -20
-5+4 = -1
2(x-5)(x+4)
Answer:
m∠E=57°
Step-by-step explanation:
∠FDE=∠FED=(4x+1)° (base angles of isos triangle)
2(4x+1)+(5x-4)=180 (angle sum of triangle)
8x+2+5x-4=180
13x-2=180
13x=180+2
=182
x=182÷13
=14
Hence, m∠E = (4x+1)°
= [4(14)+1]°
= (56+1)°
= 57°
I think the answer is option c.one
there is only one sign change in the whole equation so possiblythe answe must be one. correct me if i am wrong
B. sometimes
sometimes it’s a line and sometimes it’s dashed depending on the less than great than sign
Answer:
y= 7/10x -1
Step-by-step explanation:
Assuming you want the equation is slope intercept form, this is the format for slope intercept: y=mx+b. Since you have the slope, this is your current equation: y=7/10x+b. Next, you want to find the y-intercept. So, plug in the coordinate to the equation. This is what it should look like: -1=7/10(0) +b/ Multiply 7/10 by 0 to get 0. So, here is what you're left with: -1=b. -1 is your y-intercept. Go back to your original equation and plug in the -1. This is your final answer: y= 7/10x-1. Hope this helped!
