From both sides of the equation, 4 should have been subtracted.
The solution should look like this:
X + 4 = 28
From each side, subtract 4 :
<em>X = 24</em>
I'd like to demonstrate more steps, but the answer has already popped up, so there aren't any more steps.
Answer:
Option B is correct.
Step-by-step explanation:
Recall that the domain is the set of (unique) inputs and the range is the set of outputs (which do not have to be unique).
The set of inputs of the given relation is {-1, 9, -10, 1}, and this set is also found in Option B. The set out outputs is {7, 2, 6, -6|, which is in Option B.
Answer:
51.7661748226 degrees; 38.2338251774 degrees
Step-by-step explanation:
First, draw a diagram to illustrate this situation. Looking at angle A, Eric's height, 1.65 m, corresponds to OPPOSITE, and Eric's shadow, 1.30 m, corresponds to ADJACENT. Using SOH CAH TOA, the equation is:
tan(A) = 1.65/1.30
A = arctan(1.65/1.30)
A = 51.7661748226 deg
Looking at angle B, 1.65 m is ADJACENT and 1.30 m is OPPOSITE. Therefore, the equation is:
tan(B) = 1.30/1.65
B = arctan(1.30/1.65)
B = 38.2338251774 deg
Answer:
y = mx + b
-1 = 2/5(-3) + b
-1 = -6/5+b
-1 + 6/5 = -6/5 + 6/5 + b
1/5 = b
y = 2/5x + 1/5
Step-by-step explanation:
- write down the slope-intercept form formula
- identify your x and y of the point
- replace x and y by the point
- multiply m and x
- do addition to get b
- write down the equation by replacing m and b with their values
