Answer:
y + 3 = 1 ⋅ (x + 2).
Step-by-step explanation:
Find the equation using point-slope formula.
Slope-intercept form:
y = x − 1
Point-slope form:
y + 3 = 1 ⋅ (x + 2)
Step-by-step explanation:
when you add integers remember that the positive integers move you to the right (so the integer will increase) and negative integers move you to the left (so the integer will decrease)
Hope this helps.
<u>X AND Y INTERCEPTS</u>
1st Answer:
x = 9
Step-by-step explanation:
<u>first you want to substitute the y</u>
<h3>
0 = -2 √(25 - x + 8)</h3>
<u>move the expression to the left</u>
<h3>
2 √(25 - x) = 8</h3>
<u>divide both sides</u>
<h3>√25 - x + 4</h3>
<u>move the constant to the right</u>
<h3>
25 - x = 16</h3>
<u>calculate</u>
<h3>
-x = -9</h3>
<u>change the signs</u>
<h3>
x = 9</h3><h3>

2nd Answer:
x = -65/9 OR x = - 7 2/9, x = - 7.2
Step-by-step explanation:
<u>first you want to substitute the y</u>
<h2>
0 = -3 √(x + 9) = 4</h2>
<u>move the expression to the left</u>
<h2>
3√(x+9) = 4</h2>
<u>divide both sides</u>
<h2>
√(x+9) = 4/3</h2>
<u>move the constant to the right</u>
<h2>
x = 16/9 - 9</h2>
<u>calculate</u>
<h2>
x = -65/9</h2>
Answer:
C
Step-by-step explanation:
3/4/2/5 = 3*5/4*2
= 15 / 8
1/2x = 20
x = 20 / (1/2)
x = 20 * 2/1
x = 40 <==
