Answer:
z is equal to -0.88235294117
Step-by-step explanation:
so you first need to do is z minus 16z which is -17z.
you now have -17z is 15
you need to divide each side by -17z
so -17z divided by -17 is 1 z
and 15 divided by -17 is -0.88235294117
so z is equal to -0.88235294117
Hey there!
z - 16z = 15
-15z = 15
DIVIDE -15 to BOTH SIDES
-15z/-15 = 15/-15
CANCEL out: -15/-15 because that gives you 1
KEEP: 15/-15 because gives you the result of the z-value
SIMPLIFY IT
z = -1
Answer: z = -1
Good luck on your assignment and enjoy your day!

The equation x²– 8x – 5 = 0 can be transformed into the equation (x - p)² = q, where p and q are real numbers. What are the values of p and q?
The form (x - p)^2 = q is the form that completing the square will leave us with.
---Add 5 to both sides
x^2 - 8x = 5
---Divide the b term by 2, and square it. Then, add that number to both sides.
-8/2 = -4
(-4)^2 = 16
x^2 - 8x + 16 = 5 + 16
x^2 - 8x + 16 = 21
---Factor!
(x - 4)^2 = 21
p = 4
q = 21
Hope this helps!! :)
P and q have values of 4 and 21, respectively.
What is an expression?In mathematics, expression is defined as the relationship of numbers, variables, and functions using mathematical signs such as addition, subtraction, multiplication, and division.
The form (x - p)²= q is what we get when we complete the square.
Adding the number 5 on both sides,
x² - 8x = 5
After dividing by two, square the b term. Then divide both sides by that figure.
-8/2 = -4
(-4)² = 16
x² - 8x + 16 = 5 + 16
x² - 8x + 16 = 21
Solve the factors,
(x - 4)² = 21
p = 4
q = 21
As a result, the values of p and q are 4 and 21, respectively.

What is a quadrilateral?A quadrilateral is a four-sided polygon with four edges and four corners in geometry. The word comes from the Latin words quadri, a variant of four, and latus, which means "side." A quadrilateral is a closed shape that has four sides, four vertices, and four angles. It's made by connecting four non-collinear points. The sum of quadrilateral interior angles is always 360 degrees.
A rectangle is a quadrilateral with four right angles in Euclidean plane geometry. It can also be defined as an equiangular quadrilateral because all of its angles are equal; or a parallelogram with a right angle. A square is a rectangle with four equal-length sides.
A parallelogram is a simple quadrilateral with two pairs of parallel sides in Euclidean geometry. A parallelogram's opposite or facing sides are equal in length, and its opposite angles are equal in size.

Answer:
s = 19°Step-by-step explanation:
The angles that are directly opposite to each other are known as opposite angles. They are also termed as vertical angles or vertically opposite angles and are equal to each other.
so
106 = 6s - 8
106 + 8 = 6s
114 = 6s
s = 114 : 6
s = 19°

Answer:
3) parallel
4) y = -1/2x +5
Step-by-step explanation:
3) Two equations are parallel if they have the same slope
The equations are written in y=mx+b (standard) form, where m is the slope. Both equations have a slope of 5/4
4) The two points that are plotted are (0,5) and (4,3).
We can find the slope by using the slope equation
(3) - (5) / (4) - (0) = -2/4 = -1/2
then we can plug it in both points to find b
-1/2(4) = -2
-2 + b = 3
b = 3

rectangle, which is 4 cm wider and 2 cm shorter than the red one, has
perimeter 72 cm. Make a sketch of the rectangles expressing all dimensions in
terms of w. Then find the dimensions of the red rectangle.
Answer:
For the red triangle the width is 9 cm and the length is 24 cm. For the blue triangle, the width is 14 cm and the length is 22 cm.
Step-by-step explanation:
Red triangle: width is 9 cm, length is 24 cm, blue one width is 14 cm and the length is 22 cm. hope this helps. did this quickly! <3
Answer:
Step 1. Perimeter P means adding up all 4 sides of a rectangle.
Step 2. Let w be the width of the red rectangle
Step 3. Let w+15 be the length of the red rectangle
Step 4. Let w+5 be the width of the blue rectangle
Step 5. Let w+15-2=w+13 be the length of the blue rectangle
Step 6. Then for the blue rectangle, P=w+5+w+5+w+13+w+13=4w+36=72
Step 7. Solving 4w+36=72
Subtract 36 from both sides of the equation
4w=36
Divide by 4 to both sides of the equation
ANSWER: For the red triangle the width is 9 cm and the length is 24 cm. For the blue triangle, the width is 14 cm and the length is 22 cm.

Can someone help me with part b?
Step-by-step explanation:
the average rate of change of a function f in an interval [x-low, x-high] is
(f(x-high) - f(x-low)) / (x-high - x-low)
the year 2000 means t = 2000-1980 = 20
the year 2015 means t = 2015-1980 = 35
so, we have
(A(35) - A(20)) / (35 - 20)
((-0.6(35)² + 37.2×35 + 243) - (-0.6(20)² + 37.2×20 + 243)) / 15
((-735 + 1302 + 243) - (-240 + 744 + 243)) / 15
(810 - 747) / 15 = 63/15 = 4.2
the average change rate between 2000 and 2015 is 4.2.
that means that the use of nuclear energy in the USA increased by 4.2 billions of kilowatt hours per year during that period.
