Answer:
X=4
Step-by-step explanation:
7x+4y=28
7x+4(0)=28
7x=28
X=4
Cool. I hope she knows how to do it. (ahem)
Answer:
the answer is D
Step-by-step explanation:
the slope is -2 and the y-intercept is 12
Step-by-step explanation:
1. choose two ordered pairs from the table (x1,y1) and (x2,y2).
2. write down the slope formula
3. replace the xs and ys by their values
4. subtract
5. divide
1. to solve for the y intercept, choose any one of the ordered pairs
2. replace the letters by their values
3. multiply
Answer:
(x -5)² + (y +4)² = 100 Should be the correct answer, hope this helps :)
Step-by-step explanation:
A circle centered at (h, k) with radius r will have equation ...
... (x -h)² + (y-k)² = r²
The point satisfies the equation for the circle. Filling in the given numbers, we have ...
... (x -5)² + (y+4)² = (-3-5)² + (2+4)² . . . . . . (h, k) = (5, -4), (x, y) = (-3, 2)
... (x -5)² + (y +4)² = 64 +36
