how many solutions does this system of equations have ? PLZ HELP ASAP DUE AFTER CLASS !
Answer:
No Solution
Step-by-step explanation:
For system of equations, you must equal the equations to each other like shown below:
[tex]3x + 1 = 3x + 7[/tex]
Solve for x by subtracting 3x from both sides of the equation:
[tex]1[/tex] ≠ [tex]7[/tex]

Your laptop battery will last for exactly 6 hours before it needs to be recharged.You have had your laptop on for
2 1/2. What fraction of your battery life remains.
Answer:
[tex]3\frac{1}{2} hours[/tex]
Step-by-step explanation:
You have to subtract 2 1/2 from 6 and that will equal 3 and 1/2.
Answer:
75%
Step-by-step explanation:
6 - 3/2 is 4.5.
So the computer has 4.5 hours.
the battery will last for 6 hours so every hour on the computer is 100/6 percentage, which is 16.6666666667.
Finally multiply 16.6666666667 and 4.5 and you will get 75%
Your final answer would be 75%

Answer:
15.1
Step-by-step explanation:
The equation to solve this is 12.3 - -2.8. Since there are two negatives, it becomes a positive.
Therefore the equation becomes 12.3 + 2.8 and the answer is 15.1
Write an equation in point-slope form of the line that passes through the point (−6, 6) and has a slope of m=32
Answer:
y = 32x + 198
Step-by-step explanation:
The fastest way to go about this is to establish "m" and plug in the coordinates you want.
y = 32x + b
6 = 32 (-6) + b
6 = -192 + b
198 = b
y = 32x + 198
If x +9= 2, then x + 9 - 9 = 2 - 9
Answer: The answer is -16
x= -7
Step-by-step explanation:
now that you know the value of x, rewrite the equation, if -7 + 9=2, then -7 + 9 - 9 = 2 -9. now that its easier to understand, add and subtract to get you answer, -16

18. On Faith's math test, she received
a 85%. If there were 40
questions on the test, how many
did she get right?
Answer: 40/10=4
That means 10% of 40 is 4.
Know that means you have to times 4 by 8
4x8=32
Now you know what 80% of 40 is.
Now we need to know what the 5% is. So if 4 is 10% . 5% must be 2.
Next we have to add 2 to 32.
32 + 2 = 34
Answer is 34

Which method would be appropriate to factor the polynomial below. 55x^3-40x^2 -Difference of Squares -Basic Trinomial Factoring -AC Method -Sums of Cubes -Greatest Common Factor -Factors by grouping
Answer:
Greatest Common Factor
Step-by-step explanation:
Let [tex]55\cdot x^{3}-40\cdot x^{2}[/tex], we proceed to demonstrate the appropriate form to factor the polynomial:
1) [tex]55\cdot x^{3}-40\cdot x^{2}[/tex] Given.
2) [tex](5\cdot 11)\cdot (x^2\cdot x) +[5\cdot (-8)]\cdot x^{2}[/tex] Definition of multiplication and subtraction/[tex]a^{b+c} = a^{b}\cdot a^{c }[/tex]/[tex]-a\cdot b = (-a)\cdot b[/tex]/Associative property
3) [tex](5\cdot x^{2})\cdot (11\cdot x)+ (5\cdot x^{2})\cdot (-8)[/tex] Commutative and associative properties
4) [tex]5\cdot x^{2}\cdot (11\cdot x-8)[/tex] Distributive property/Definition of subtraction/Result
Hence, we conclude that this polynomial can be factored by Greatest Common Factor.

Answer:
E. 11
Step-by-step explanation:
Replace the m with 11.
11-8[tex]\leq[/tex] 2 this would simplify to
3 [tex]\leq[/tex]2 which is false.
However if you took m and replaced it with 10
10-8[tex]\leq[/tex]2 and simplified
2[tex]\leq[/tex]2 which is true. Therefore any number 10 or lower would make this true.

a sphere has a volume of 4500 cubic inches. What is the radius off the shpere
Answer:
The radius of sphere with volume 4500 cubic inches is 10.24 inches.
Step-by-step explanation:
Let V be the volume of the sphere
Given
Volume of sphere = V = 4500 cubic inches
Let r be the radius of the sphere
The volume of the sphere is given by the formula
[tex]V = \frac{4}{3}\pi r^3[/tex]
Putting the known values
[tex]4500 = \frac{4}{3} * \frac{22}{7} * r^3\\4500 = \frac{88}{21} * r^3\\r^3 = \frac{21}{88} * 4500\\r^3 = 1073.8636[/tex]
Taking cube root on both sides
[tex]\sqrt[3]{r^3} = \sqrt[3]{1073.8636} \\r = 10.2403[/tex]
Rounding off to nearest hundredth
The radius is: 10.24 inches.
Hence,
The radius of sphere with volume 4500 cubic inches is 10.24 inches.

Give work for each
9514 1404 393
Answer:
There are 95 boys.There are 76 girls.Step-by-step explanation:
The fraction that is boys is 5/(5+4) = 5/9. That fraction of the total is ...
boys = 5/9 × 171 = 95
Girls are the remainder:
girls = 171 -95 = 76
There are 95 boys and 76 girls in the band.

What is the slope of the line shown below?
Answer:
[tex]m = \frac {1}{4}[/tex]
Step-by-step explanation:
Slope formula
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Here
[tex](x_1, y_1) = (-3, -1) \ \ and \ \ (x_2, y_2)= (5, 1)[/tex]
Slope can be calculated as
[tex]m = \frac{1-(-1)}{5-(-3)}[/tex]
[tex]m = \frac{2}{8} \\m = \frac {1}{4}[/tex]
