Question on picture!!!!!!!!
Answer:
1st option
Step-by-step explanation:
Given y varies inversely as x then the equation relating them is
y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation
To find k use (3, 8 ) , that is x = 3 when y = 8 , then
8 = [tex]\frac{k}{3}[/tex] ( multiply both sides by 3 )
24 = k
y = [tex]\frac{24}{x}[/tex] ← equation of variation

A circle is centered at the point (-7, -1) and passes through the point (8, 7).
The radius of the circle is
units. The point (-15, lies on this circle.
Answer:
radius = 17 units
equation of the circle =( x -h)^2 +(y -k) ^2 = r^2
or , (8 -(-7))^2 + (7-(-1))^2 = r^2
or, (8+7)^2 + (7 + 1)^2 = r^2
or, (15)^2 + (8)^2 =r^2
or, 225 + 64 = r^2
or 289 =r^2
or, 17^2 = r^2
or, r = 17 units
Please check the point by inserting centre(-7,-1) in place of (h,k ) and point in (x , y) and radius in r in the following equation
(x-h)^2 + (y - k)^2 = r^ 2.

Answer:
1, 3, and 4 would be correct answers
Step-by-step explanation:
1.) -x - 2x - 3y - 2y + 1 + 1 = -3x -5y + 2
2.) -3x + 2y + 3y + 2 = -3x + 5y + 2
3.) -3x - y - y - y - y - y + 2 = -3x - 5y + 2
4.) -x - x - x - y - y - y - y - y + 1 + 1 = -3x - 5y + 2
5.) x + x + x + y + y + y + y + y + 1 + 1 = 3x + 5y + 2
Hope this helps!

Find the GCF of the first two terms and the GCF of the last two terms for the polynomial.
2z3 + 12z2 – 5z – 30
A.
z2; –5
B.
2z; –5
C.
2z2; –5
D.
2z2; 5
Answer:
C.
2z2; –5
Step-by-step explanation:
Add and subtract the second term to the expression and factor by grouping.
( z + 6 ) ( 2 z 2 − 5 )
Answer:
2z^2; –5
Step-by-step explanation:
2z3 = 2 • z • z • z 12z2
= 2 • 2 • 3 • z • z
The GCF is 2z2.
–5z3 = –1 • 5 • z • z • z
–30 = –1 • 5 • 6
The GCF is –5.

In the figure, d || m. What is the value of x?
Answer:
x = 53
Step-by-step explanation:
The angle labeled with the expression "2x - 20 " and the angle with the measure of 86 degrees are opposite interior angles.
Opposite interior angles are congruent
This means that 2x - 20 = 86
This is our equation.
We now solve for x using basic algebra
2x - 20 = 86
step 1 add 20 to each side
-20 + 20 cancels out
86 + 20 = 106
now we have 2x = 106
step 2 divide each side by 2
2x / 2 = x
106 / 2 = 53
we're left with x = 53

If 12 cans of cat food cost $40.00 then
how much would it cost for 60 cans ?
Answer:
$200.00
Step-by-step explanation:
because if you do a ratio:
12=40
60=?
60 divided by 12 is 5, and whatever you do to the top you must do to the bottom, so then you gotta do 40 times 5=200
pls help with this !!!!!!!
Both methods assume a normal distribution of the data, but the z-tests are most useful when the standard deviation is known.
OR u can use , z-tests are used when we have large sample sizes (n > 30), whereas t-tests are most helpful with a smaller sample size (n < 30). Both methods assume a normal distribution of the data, but the z-tests are most useful when the standard deviation is known.
A transformation is a of a figure to the or
Answer: change, position, shape
Step-by-step explanation:
A line has this equation: y = -8x + 8,
Write an equation for the parallel line that goes through (9,7)
[tex]=======================================[/tex]
parallel lines have the same slope; it means that if we have a line with a slope of -8, then the line parallel to the given line has the same slope (-8)
now, we are also given a point that the line passes through:
(9, 7)
we can use point-slope form:
[tex]\pmb{y-y1=m(x-x1)}[/tex]
[tex]\pmb{y-7=-8(x-9)}[/tex] (point-slope form)
now, convert to slope-intercept form, if necessary:
[tex]\pmb{y-7=-8x+72}[/tex]
[tex]\pmb{y=-8x+72+7}[/tex]
[tex]\pmb{y=-8x+79}[/tex]
[tex]================================[/tex]

A triangle has angle measurements of 56°, 54°, and 70°. What kind of triangle is it?
Answer and Step-by-step explanation:
The answer is acute.
Acute angles are angles that have a degree that is less than 90 degrees.
Obtuse angles are angles that have a degree that is more than 90 degrees.
Right angles are angles that are 90 degrees.
Our triangle has all angles that are less than 90 degrees, so it is an acute triangle.

Please answer with an equation that would represent the situation.
A bagel shop offers a mug filled with coffee for $7.75, with each refill costing $1.25. Kendra spent $31.50 on the mug and refills last month. How many refills did Kendra buy?
Answer:
7.75+1.25x=31.50
Step-by-step explanation:
so in the end the answer is 19
Answer:
19 refills
Step-by-step explanation:
7.75+1.25x=31.50
Subtract the 7.75 on the other side..
1.25x=23.75
Then divide 1.25 from the 23.75
So, x which is the refills equal 19
Given the Production Function Q = 72X + 15X 2 - X 3 , where Q =Output and X=Input (5 marks) a) What is the Marginal Product (MP) when X = 8? B) What is the Average Product (AP) when X = 6? C) At what value of X will Q be at its maximum? D) At what value of X will Diminishing Returns set in?
Answer:
a.) Marginal Product (MP) = 120
b.) Average Product = 126
c.) At x = 12, the output is maximum.
d.) After 5 levels of inputs diminishing returns set in.
Step-by-step explanation:
Given that,
Q = 72x + 15x² - x³
a.)
Marginal Product is equal to
[tex]\frac{dQ}{dx} = 72 + 30x - 3x^{2}[/tex]
At x = 8
MP = 72 + 30(8) - 3(8)²
= 72 + 240 - 192
= 120
∴ we get
Marginal Product (MP) = 120
b.)
Average Product is equals to
= [tex]\frac{Q}{x}[/tex]
= 72 + 15x - x²
At x = 6
Average Product = 72 + 15(6) - 6²
= 72 + 90 - 36
= 126
∴ we get
Average Product = 126
c.)
For Maximizing Q,
Put [tex]\frac{dQ}{dx} = 0[/tex]
⇒72 + 30x - 3x² = 0
⇒24 + 10x - x² = 0
⇒x² - 10x - 24 = 0
⇒x² - 12x + 2x - 24 = 0
⇒x(x - 12) + 2(x - 12) = 0
⇒(x + 2)(x - 12) = 0
⇒x = -2, 12
As items can not be negative
∴ we get
At x = 12, the output is maximum.
d.)
Now,
For Diminishing Return
[tex]\frac{d(MP)}{dx} = \frac{d^{2}Q}{dx^{2} } < 0[/tex]
⇒30 - 6x < 0
⇒-6x < -30
⇒6x > 30
⇒x > 5
∴ we get
For x > 5, the diminishing returns set in
i.e.
After 5 levels of inputs diminishing returns set in.

In the above figure, m∠A = 22° and m∠B = (2x + 16)°. If angles A and B are complementary angles, what are the value of x and the measure of angle B?
A.
x = 26, m∠B = 68°
B.
x = 71, m∠B = 158°
C.
x = 48, m∠B = 68°
D.
x = 26, m∠B = 52°
Answer:
A.
Step-by-step explanation:
22+(2x + 16)+90=180
combine like terms: 90+22+16=128
180-128=52
52=2x
52/2 = 2x/2
