Answer:
The answer is 1
Step-by-step explanation:
2(a+7)−7=9
Step 1: Simplify both sides of the equation.
2(a+7)−7=9
(2)(a)+(2)(7)+−7=9(Distribute)
2a+14+−7=9
(2a)+(14+−7)=9(Combine Like Terms)
2a+7=9
2a+7=9
Step 2: Subtract 7 from both sides.
2a+7−7=9−7
2a=2
Step 3: Divide both sides by 2.
2a

Answer:
4.9 units
Step-by-step explanation:
We are dealing with a Right angle triangle, and the c is actually the hypotenuse. We are given the measures of a and b.
a being 4, and b being 3.
We need to use the Pythagorean Theorem to solve this.

we can rewrite this as;

Calculation time
15 + 9 = c
c = 24
Now we find the square root of each equation to determine what
is.

4 + 3 = 4.89897948557
Let's round that to the nearest tenth.
4.9 units

Answer:
1/2
Step-by-step explanation:
The slope of the points (4,-3) and (3,-1) is -2
The slope of a line perpendicular to said points would be the opposite reciprocal which would be 1/2
heres how you'd find the initial slope of the points
(4, -3)
-1 +2
(3, -1)
Slope= rise/run= 2/-1= -2
Answer:
yes
Step-by-step explanation:
Use substitution method
3(2)+14=2(10)
6+14=20
20=20
Hope this helps. Have a nice day you amazing bean child.
