I hope this helps you
slope = 5-0/-6-(-3)= -5/3
(0,0)
m.(x1-x)=y1-y

Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
2*x^2-3*x-(2)=0

</span><span>Step 2 :</span>Trying to factor by splitting the middle term
<span> 2.1 </span> Factoring <span> 2x2-3x-2</span>
The first term is, <span> <span>2x2</span> </span> its coefficient is <span> 2 </span>.
The middle term is, <span> -3x </span> its coefficient is <span> -3 </span>.
The last term, "the constant", is <span> -2 </span>
Step-1 : Multiply the coefficient of the first term by the constant <span> <span> 2</span> • -2 = -4</span>
Step-2 : Find two factors of -4 whose sum equals the coefficient of the middle term, which is <span> -3 </span>.
<span> -4 + 1 = -3 That's it</span>
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -4 and 1
<span>2x2 - 4x</span> + 1x - 2
Step-4 : Add up the first 2 terms, pulling out like factors :
2x • (x-2)
Add up the last 2 terms, pulling out common factors :
1 • (x-2)
Step-5 : Add up the four terms of step 4 :
(2x+1) • (x-2)
Which is the desired factorization
Neither because they are different size and mirrored it could’ve been congruent but it’s double the size and congruent is mirrored and the same size
3.5 + 4.5 = 8

Answer:
B. 67°
Step-by-step explanation:
An acute angle is an angle that has a degree that's less than 90°. This eliminates answers "C," and "D."
The information above states that the triangle is right, meaning that one of its angles is 90°, and there's another angle that's 23°.
So add these together, and subtract from 180 (all triangles are 180°), to get the other acute angle:
90 + 23 = 113
180 - 113 = 67°
<u>The missing acute angle is 67°</u>
