Answer:
(-1, 5)
Step-by-step explanation:
using substitution method
y = -2x + 3 plug y into second equation
-x + 3y = 16
-x + 3 (-2x + 3) = 16
-x - 6x + 9 = 16
-7x + 9 = 16
-7x = 7
x = -1 now that you know what x equals, plug it into one of the original equations
y = -2 (-1) + 3
y = 2 + 3
y = 5
thus you get the answer (-1, 5)
Michael draws a quadrilateral that has four congruent sides, but does not have congruent angles which best describes
the quadrilateral formed?
A rectangle
B rhombus
C square
D trapezoid
Answer: Rhombus
Step-by-step explanation:
Quadrilaterals have four sides
The quadrilateral Michael drew is best described as a (b) rhombus
From the question, we understand that:
The four sides of the shape are congruentThis means that the shape can be a rhombus or a square (because they have congruent sides)
The four angles of the shape are not congruentA square has four congruent angles, while the angles in a rhombus are not congruent
Hence, the shape is best described as a rhombus

find the slope of the following ^ :))
|
Answer:
m [slope] = 0
Step-by-step explanation:
When the slope is 0, x cancels out so the y value will remain the same.
There are several methods to finding slope but the easiest way to do this is by dividing the second y value - first y value by the second x value - first x value.
m = ∆y/∆x = y2-y1/x2-x1
You y2 and x2 are interchangable with y and x, because y1, and x1 are part of the starting coordinate,.
The reason you subtract the second
value from the first is because in a directly proportional relationship, y increases as x increases so the next x values will have a greater y value, this is a measure of steepness.
So the slope is:
-1 - -1 / 3 - -2 = -1 + 1 / 3 + 2 = 0 / 5 = 0.

The fox population in a certain region has a continuous growth rate of 6 percent per year. It is estimated that the population in the year 2000 was 19100.
(a) Find a function that models the population t years after 2000(t=0 for 2000).
Hint: Use an exponential function with base e.
Your answer is P(t)=
(b) Use the function from part (a) to estimate the fox population in the year 2008.
Your answer is (the answer must be an integer)
a)
[tex] P(t) = 19100. e^{0.06t} [/tex]
b) P(8) =30866
Use formula:
[tex] P(t) = P. e^{rt} [/tex]
a)
Here, P = 19100
r = 6% = 0.06
[tex] P(t) = 19100. e^{0.06t} [/tex]
b) t = 2008 - 2000 = 8

Mahmoud is doing some plumbing repairs. He runs a pipe through a rectangular wall making a 70 angle. Afterward, he puts the pipe
through another wall which is parallel to the first. Mahmoud can therefore assure the homeowner that the pipe forms a ____ angle
with the second piece of wall.
Answer:
The correct option is;
(D) 70°
Step-by-step explanation:
By running the pipe through the first wall, to the second wall which is perpendicular to the first, we have;
The angle the pipe makes = 70°
Therefore, due to the spring back effect the formed by the pipe when bent 90° is 70°
Therefore, By running the pipe from the second wall, to the third wall which is parallel to the first, and perpendicular to the second wall, the angle the pipe forms is also a 70° angle
Mahmoud can therefore assure the home owner that the pipe forms a 70° angle with the second piece of the wall.

A video screen is 16 in. by 12 in. tall. What is the width of the largest complete image possible for a photograph that is 4 in. wide by 6 in. tall?
Answer:
16 inches, and 10 inches tall, aka Answer D.
So because, they are asking the largest image for the photograph,
so 8 * 2 = 16
and 10 * 2 = 20 but 20 can't go into 12.
Step-by-step explanation:
I think this is right sry if its not
The width of the largest complete image possible for a photograph that is 4 in. wide by 6 in. tall is 8 in option (B) 8 in is correct.
What is a scale factor?The ratio among comparable dimensions of an object and a model with that object is known as an exponent in algebra. The replica will be larger if the scale factor is a whole number. The duplicate will be lowered if the step size is a fraction.
We have:
A video screen is 16 in. by 12 in. tall.
To find the width of the largest complete image possible for a photograph that is 4 in. wide by 6 in. tall, we can use the scale factor:
Applying the similarity law:
6/12 = 4/x
1/2 = 4/x
x = 4×2
x = 8 in
Thus, the width of the largest complete image possible for a photograph that is 4 in. wide by 6 in. tall is 8 in option (B) 8 in is correct.

The total cost of five pens and eight mechanical pencils is 12.65. The cost of each mechanical pencil is 0.75 cents. Which represents the cost of each pen
Answer:
the cost of each pen is 1.33
Step-by-step explanation:
if you multiply 0.75 by 8 you get 6 after that you subtract 6 from 12.65 which means you have 6.65 which you divide by 5 which equals 1.33
