Answer:
D. 10x - 5
General Formulas and Concepts:
<u>Algebra I</u>
- Terms/Coefficients/Degrees
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 2x + 5x
g(x) = 3x - 5
(f + g)(x) is f(x) + g(x)
<u>Step 2: Simplify</u>
f(x) = 7x
g(x) = 3x - 5
<u>Step 3: Find</u>
- Substitute: (f + g)(x) = 7x + (3x - 5)
- Combine like terms: (f + g)(x) = 10x - 5
Answer:
Answer is at the bottom!!
Step-by-step explanation:
y = - \frac{2}{5} x - 2
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
rearrange 2x + 5y = 10 into this form
subtract 2x from both sides
5y = - 2x + 10 ( divide all terms by 5 )
y = - \frac{2}{5} x + 2 ← point- slope form with slope m = - \frac{2}{5}
Parallel lines have equal slopes hence
y = - \frac{2}{5} x + c is the partial equation of the parallel line
to find c, substitute ( 5, - 4 ) into the partial equation
- 4 = - 2 + c ⇒ c = - 4 + 2 = - 2
y = - \frac{2}{5} x - 2 ← equation of parallel line
Hope this helps!!
He started at 418 above sea level. descended means he moved down so subtract 88 from 418:
418 - 88 = 330 feet.
He then climbed 120, so now add that to the 330:
330 + 120 = 450
He is now at 450 feet above sea level.
Answer: A) AD
Step-by-step explanation:
Given: Quadrilateral ABCD is the result of a reflection of quadrilateral EFGH over the line.
We know that after reflection each point on the pre-image has a corresponding point on its image that is equidistant from a given line of reflection.
Since, EH shows the first and the last character of the name .
Thus, the line segment in the image corresponds to EH in the pre-image is AD because A is the first and D is the last character of the pre-image.
