Answer:
The rule is y = -7x + 5
→ Other values of x;
→ Other values of y;
Step-by-step explanation:
» Take points (1, -2) and (3, -12) from the table.
☑ General equation of a line is y = mx + c
- m is the slope
- c is y-intercept

Answer:
given
x=5
y= -2
expression :-> 7(2(5)-3(-2))
7(10+6)
7 * 16
112
therefore 112 is ur ans
Answer:
um 1/2???
Step-by-step explanation:

Answer: PC = 5</h3>
================================================
Work Shown:
AB+BC+CD = AD .... segment addition postulate
BC+BC+CD = AD ... replace AB with BC (since AB = BC)
BC+BC+BC = AD ... replace CD with BC (since BC = BC)
3*BC = AD .... combine like terms
3*BC = 12 .... replace AD with 12
BC = 12/3 .... divide both sides by 3
BC = 4
For right triangle PBC, the legs are BP = 3 and BC = 4. We can use the Pythagorean Theorem to find that the hypotenuse is PC = 5
The steps are shown below
(BP)^2+(BC)^2 = (PC)^2
3^2+4^2 = (PC)^2
9+16 = (PC)^2
25 = (PC)^2
(PC)^2 = 25
PC = sqrt(25)
PC = 5
The other parts of the diagram seem to be thrown in as a distraction.
Answer:
A. (x-5)(x-5)
Step-by-step explanation:
We need to factor x^2-10x+25 into the form (x+y)(x+y) where 2y=-10 and y^2=25
2y=-10
y=-5
So this becomes (x-5)(x-5)
Hope this helped!
