Answer:
one solution, no solution, infinitely many solutions
Step-by-step explanation:
I rearranged the first equation into x=6-2y
plug that into the second equation
2(6-2y)-3y=26
12-4y-3y=26
12-7y=26
-7y=14
y=-2
Then you plug that into one of the equations
x+2(-2)=6
x-4=6
x=10
The solution to the first system is (10,-2)
the second system already has one equation as something equal to a single variable so you just plug that into the other one
4x-2(2x-4)=-6
4x -4x +8 =-6
8=-6
this is a false statement so the system of equation has no solution
Lastly I rearranged the first equation into y=2x-4 and then plug that in
6x-3(2x-4)=12
6x-6x+12=12
12=12
this statement is true so the system of equations has infinite solutions

Write a decimal that the model represents
Answer:
number = 0.011
Step-by-step explanation:
Decimal Representation
The model is shown in the figure. It has a form of a cube where each face is divided into 10 equal squares, forming a 10x10x10=1,000 smaller cubes piece.
Out of that 1,000 cubes, only 11 are shaded. This leaves us to think the decimal represented by the model is the division between the shaded cubes by the total cubes, thus:
[tex]number= \frac{11}{1,000}[/tex]
Dividing:
number = 0.011

Jessica is an elite marathon runner. For her most recent long run, she ran 15 miles in 90 minutes. What is her speed?
Answer:
10 mph
Step-by-step explanation:
So speed is usually written in miles per hour (mph) so I'm assuming that's how you want it.
90 minutes is 1.5 hours

You have the same bowl, with 5 orange, 6 blue, 3 green, 4 red and 7 yellow candies. You take out an orange candy
from the bowl. What is the new probability that you will draw another orange candy?
A 1/5
B 1/6
C 1/8
D 5/24
Answer:
A) 1/5
Step-by-step explanation:
There are 25 candies total, and you want to choose the 5 orange candies there.
That's 5/25.
Simplifying, we divide both sides by 5.
Thus, we get:
1/5.
tony is taking a 5 year loan in the amount of $15,000. The interest is continuously compounded at an annual rate of 7%. How much will he owe, in dollars, at the end of the loan term?
Answer:
$21,038.28
Step-by-step explanation:
Use the equation 15000(1.07)^5 since 1.07 equals to 7% and you are loaning more money to Tony's account for 5 years. You should get $21,038.28 as your result.

Step-by-step explanation:
Answer:
D) 28.90
Step-by-step explanation:
28.90 divided by 2 = 14.45 + 1.12 (sales tax) = 15.15 (which was the price he had paid)

An object moves along a straight line so that at any time t , for 0≤t≤8 , its position is given by x(t)=5+4t−t2 . For what value of t is the object at rest?
A. t = 2
B. t = 4
C. t = 9/2
D. t = 5
Answer:
D. t = 5
when the object is at rest => x(t) = 0
<=> -t^2 + 4t + 5 = 0
<=> t^2 - 4t - 5 = 0
<=> (t - 5)(t + 1) = 0
=> t = 5 or t = -1
but t》0
=> t = 5
The value of t if the object at rest is 2 secs: Option A is correct
Given the position of the object moving in a straight line expressed as:
x(t)=5+4t−t²
The velocity of the body at rest is zero
Get the velocity fucntion.
v(t) = d(x(t))/dt = 4 - 2t
Since v(t) = 0
0 = 4 - 2t
-4 = -2t
t = 2
Hence the value of t if the object at rest is 2 secs

Help ASAP find the values of x and y
Answer:
x = 48° and y = 70°
Step-by-step explanation:
As it is an isosceles triangle so base angles of isosceles triangle are equal
x +7° = 55°
x = 55° - 7°
Therefore x = 48°
Now
x + 7 = (48 + 7)°= 55°
Calculating the value of y as sum of angles of triangle is equal to 180°
y + 55° + 55° = 180°
y + 110° = 180°
y = 180° - 110°
Y = 70°
Hope it will help :)
Answer:
x=48
y=70
Step-by-step explanation:
Key skills required are triangles, isosceles triangles, one variable equations, interior angle sums
1) You have to start with the fact that the triangle is isosceles. This means that the 2 base angles (x+7 and 55) are equal to each other.
An isosceles triangle has 2 sides equal and 2 angles equal.
2) With the explanation above --> x+7=55
3) Subtract 7 from both sides and you will get x=48
4) The sum of all the angles in a triangle is 180 degrees. The two bottom angles are 55 degrees each, making their sum 55+ 55= 110 degrees.
5) 110 degrees + y degrees = 180
6) subtract 110 from both sides and y would equal 70.
Hope you understood and have a nice day!! :D

Write the equation in standard form
using factoring.
f(x) = (2x
+
1)(x – 4)
Answer:
2x^2 - 7x - 4
Step-by-step explanation:
Given the expression f(x) = (2x+1)(x – 4)
To write it in standard form, we need to factorize it
(2x+1)(x – 4)
= 2x(x) - 2x(4) + x - 4
= 2x^2 - 8x + x - 4
= 2x^2 - 7x - 4
hence the expression in standard form is 2x^2 - 7x - 4
