<em><u>Complete Question:</u></em>
What is the y intercept of y = -3-7x
<em><u>Answer:</u></em>
<h3>The y intercept is (0, -3)</h3>
<em><u>Solution:</u></em>
<em><u>Given equation is:</u></em>
y = -3 - 7x
The y intercept is the point where the line crosses the y axis
<u>Finding y intercept:
</u>
To determine the y-intercept, we set x equal to zero and solve for y
Substitute x = 0 in given equation
y = -3 - 7(0)
y = -3 - 0
y = -3
Thus the y intercept is (0, -3)
Answer:
second choice
Step-by-step explanation:
The given sums ∑ have j = 1, j = 2, j = 3, j = 4, j = 5
Consider first j = 1 and substitute in the answers to see if we get the first term of the series -3
✅
2·1 - 5 = 2-5 = -3 ✅
3·1 - 6 = 3-6 = -3 ✅
❌
We see that last choice gives us as first term to be 1 not -3 so eliminate that possibility.
Consider now j = 2 and substitute in the answers to see if we get the second term of the series -1
✅
2·2 - 5 = 4-5 = -1 ✅
3·2 - 6 = 6-6 = 0 ❌
We see that third choice gives us as second term to be 0 not -1 so eliminate that possibility.
Consider now j = 3 and substitute in the answers to see if we get the third term of the series 1
❌
2·3 - 5 = 6-5 = 1 ✅
We see that first choice gives us as third term to be -1/3 not 1 so eliminate that possibility.
Now we are left with the second choice as the only possibility.
It should be b but i don’t have paper with me so i’m not sure
Area of the circle outside
= πr2
= π(5)2
=25 π
Area of the bigger circle inside
= π x(3)2
= 9 π
Area of the smaller circle inside
= π x (2)2
= 4 π
Area of shaded region
= 25π - 9π - 4π
= 12π square unit
Answer:
30
Explanation:
It’s pretty simple actually, you just need to get the square root of 900 by seeing what two equal numbers give you 900. The answer in this scenario would be 30 since 30x30 would give you 900. Since it is a square all sides are equal and your answer would only be 30.
Hope this helped you :)
