Answer:
Step-by-step explanation:
-7k = 0
Divide both sides by (-7)
k = 0
17) c - 4 = -23
Add 4 to both sides
c - 4 + 4 = -23 + 4
c = - 19
Answer:
y = 2x + b (the second answer choice)
Step-by-step explanation:
The slope-intercept form is y = mx + b (the m representing slope and the b representing y-intercept). Put the points in ratio form as a fraction and subtract the ratio with the smallest numbers from the ratio with the largest ratio (5/1 - 1/-1) to get 4/2. When simplified, it becomes 2/1, so the slope is 2. Using the slope found previously, subtract 1 from the x of (1, 5) and 2 from the y of (1, 5) to get the y-intercept. The resulting point is (0, 3), so the y-intercept is 3. Replace the m with the found slope (2) and b with the found y-intercept (3) to end up with y = 2x + 3.
Answer:Take the alternating sum of the digits in the number, read from left to right. If that is divisible by 11, so is the original number. So, for instance, 2728 has alternating sum of digits 2 – 7 + 2 – 8 = -11. Since -11 is divisible by 11, so is 2728.

Answer:
negative 5
Step-by-step explanation:
4-9= -5
Answer:
<h2>y=2x+0 (y=2x)</h2>
Step-by-step explanation:
so we know that y=mx+c
c is the point where the line crosses the y-axis
y=mx+0
m is the gradient
the gradient is rise/run
pick any two points
so it is 2/1
2/1 is 2
therefore it is
y=2x+0
