Answer:
y = x^2 +2x -35
Step-by-step explanation:
Multiply the binomials. The distributive property is helpful.
y = x(x -5) +7(x -5) . . . . the terms of the first binomial multiplied by the second
= x^2 -5x +7x -35 . . . . eliminate parenthses
y = x^2 +2x -35 . . . . . . collect terms
Answer:
7 oof
Step-by-step explanation:
The third one, this is because you take your y2 and y1 values (y2=0 and y1=9 because these are the two y values given to you from each coordinate) and subtract 0-9. then you do the same, but with the x2 and x1 values. so your x1 value is 3 and your x2 value is 0, so you subtract 0 from 3. divide your second answer from the first answer, to get a gradient of -1/3 x. now using the first coordinate (0,9) you know that the y coordinate is 9. as the x value =0, we know that the line is passing through the y axis at 9 so 9 is your y intercept. this gives you the equation -1/3x+9. hope this helped and wasn't too confusing!

15)
∠EAD ≅ ∠CAB . . . . . . reflexive property. An angle is congruent with itself.
∠AED ≅ ∠ACB . . . . . . given
ΔABC ≅ ΔADE . . . . . . angle-angle similarity: If two angles are congruent, all three angles are congruent and the triangles are similar.
