Answer:
x = 145°
Step-by-step explanation:
We know that y = 98°, so we can find ∠DBC:
180°-y = ∠DBC
180°-98° = 82°
We also know that z = 63°, therefore we can apply <u>exterior angle of triangles</u> to find x.
∠DBC + z = x
82°+63° = x
x = 145°
Answer:
Step-by-step explanation:
12) The amount of the initial deposit is $1000
13) the slope is (y2 - y1)/(x2 - x1)
Slope = (4000 - 3000)/(6 - 4)
Slope = 1000/2 = 500
The y intercept is the value of y when x is zero. Therefore,
y intercept = 1000.
14) The equation of a straight line represented in the slope intercept form is
y = mx + c
Where
m represents slope
c represents intercept
Therefore the equation is
y = 500x + 1000
15) The slope represents rate of change in the amount saved with respect to time in months.
Answer:
see below
Step-by-step explanation:
2d+21 ≤11
Subtract 21
2d+21-21 ≤11 -21
2d ≤-10
Divide by 2
2d/2 ≤-10/2
d≤-5
You will need to follow order of operations, which states that operations must be completed in the following order: parentheses, exponents, multiplication and division, and then addition and subtraction.
In this case, there are no parentheses and no exponents, so we will start with the multiplication and division:
Now, we will finish by doing addition and subtraction:
Our answer is .
1 + 1x
OR
1 + x
They mean the same thing! Hope this helps!
