Answer:
7+<u>21</u>+15+19+.....+79
Here 21 be replaced by <u>11</u>.
Now., common diffrence btw terms , d = 11-7 = 4
first term , a = 7
Last term , l = 79
number of terms = ( a + l ) ÷ d
=( 7 + 79 ) ÷ 4 = 86 ÷ 4 = 21.5 { It cannot be in decimal }
<u>There's some mistake in the terms you provided please check your question again...</u>
Answer:
The x-intercept is the point (22,0)
Step-by-step explanation:
step 1
Find the slope
The formula to calculate the slope between two points is equal to
take the points
(-38,40) and (-23,30)
substitute the given values
step 2
Find the equation of the line in point slope form
we have
substitute
step 3
Find the x-intercept
Remember that the x-intercept is the value of x when the value of y is equal to zero
so
For y=0
solve for x
Multiply by 3 both sides
therefore
The x-intercept is the point (22,0)
Hm it’s false , your welcome have a great day!
In this question, you're solving by adding the two expressions together.
(f+g)(x) is the same as:
3x - 1 + x + 2
Solve:
3x - 1 + x + 2
<em>combine like terms:</em>
4x - 1 + 2
4x + 1
Answer:
4x + 1
