<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>
</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: = 5wx
Step-by-step explanation:
you revers the equation like this
= 35 divided by 7
= 5 then you place the wxy together
Answer:
3B
Step-by-step explanation:
The greatest common factor is the greatest number that will divide two values. We have two values 3B and 30B. Each has numbers which multiply together to give the number. We need to find the highest value or most in common they share. Each has the factors:
3B: 1,3,B
30B: 1, 3, 5, 6, 10, B
Both have 3 and B has factors. Our GCF is these two factors.
Number of possible outcome = 6
Number of outcomes greater than 4 = 2
<em>(face with number 5 + face with number 6)</em>
P(greater than 4) = 2/6 = 1/3
If she rolled it 60 times,
P(she will get greater than 4) = 1/3 x 60 = 20
Answer: 20 times
5.8 to 1 decimal place would be 0.58
