<span>Two </span>Angles<span> <span>are </span></span>Complementary<span> <span>when they add up to 90 degrees (a Right </span></span>Angle). They
don't have to be next to each other, just so long as the total is 90 degrees.
So (5x + 4) + ( 7x + 2) = 90
12x + 6 = 90
12x = 90 – 6
12x = 84
<span>X = 7</span>
Ok so if you divide that it will be a decimal
so it is 0.68
Answer:
53
Step-by-step explanation:
To evaluate 6x + 11, we must substitute the value of x.
Since we know that x = 7, it is easier to evaluate the expression;
6x + 11
6(7) + 11
Since 6 is outside the parenthesis, we must multiply everything inside the parenthesis by 6;
6(7) + 11
42 + 11
When you add the two numbers you get:
53
That would be D) The slope of the graph will be changed.
