Answer:
x=12, y=-3
Step-by-step explanation:
Plug (-4y) in for x in the top equation. The equation will now read 2(-4y) + 7y = 3. Distribute the 2 into the perenthecies getting: -8y+7y=3. -8+7 is -1 giving -y+3. Divide by -1 making y = -3. Plug -3 back into the top equation and solve for x: 2x + 7(-3)=3. 2x-21=3. 2x=24. x=12.

Answer:
see explanation
Step-by-step explanation:
Writing an expression for the perimeter (P) of the triangle
P = x - 4.5 + x - 4.5 + x - 4.5 ← as a sum
P = 3(x - 4.5) ← as a product

Answer:
V = x³ - 3x² + 3x - 1
Step-by-step explanation:
The volume (V) of a cube is calculated as
V = s³ ( s is the measure of the side )
Here s = x - 1 , thus
V = (x - 1)³
= (x - 1)(x - 1)(x - 1) ← expand the second pair using FOIL
= (x - 1)(x² - 2x + 1) ← distribute
= x³ - 2x² + x - x² + 2x - 1 ← collect like terms
= x³ - 3x² + 3x - 1

5Step-by-step explanation:
Describe how you can tell whether a line’s slope is greater than 1, equal to 1, or less than 1
If the slope is greater than one, it would have a positive slope and it is moving vertically up the y axis.
If the slope is equal to one, Guessing that the y axis is counting by 1 you could tell the slope is 1 by looking to see if first, it is moving positively up the y axis or look at what points it is intersecting. If it's counting every 1 point (For example) If the start of the slope began on the origin (0, 0) than it should count (0, 0) - (1, 1) - (2, 2) - (3, 3) etc..
Now the more "confusing" one. if the slope is less than one it can be a flat line on the graph. Not negative nor positive, Its neutral. You can also tell if its positive if it is moving down the graph, Negatively. or if it is moving into a different quadrant from. (0, 0)

For what value of k does the equation 5x – 32 = kx + 3 have no solution?
Step-by-step explanation:
5x - 32 = kx + 3
(5 - k)x = 35
This equation fails when (5 - k) = 0, or k = 5.
Solve for b.
b + 0.9 = 5.1
Enter your answer, as a decimal, in the box.
Answer:
4.2
Step-by-step explanation:
This one is pretty easy cause all you need to do is subtract 0.9 from 5.1
5.1 - 0.9 = 4.2
And to check it plug and play
4.2 + 0.9 = 5.1
Therefore, your answer is 4.2

ted's company has recieved an order to print 10^6 pages. ted's company has 100 machines , each of which can print 10^4 pages a day. ted's company can print the 10^6 pages in blank.
in exponent form, this number of days can be represented as blank
Answer:
1 day ; 10^0
Step-by-step explanation:
Given that:
Order received = 10^6 pages
Number of machines = 100
Daily printing capability by each machine = 10^4
Hence, total output per day = (10^4) * 100 = 10^4 * 10^2 = 10^4+2 = 10^6
Number of days required = number of order / daily output
Number of days = 10^6 / 10^6 = 1
In exponent form:
10^6 / 10^6 = 10^6-6 = 10^0

Describe and correct the error a student made when graphing the linear equation y=−
3
4x−6.
Answer:
In step 1 the y-intercept should be plotted at (0,-6)
Step-by-step explanation:
Remember that to find the Y intercept in any linear equation you need to use 0 as your X value, this means taking the formula in the y=mx+b form and replacing X with a 0.
Since the formula is y = -3/4x -6
We just insert a 0 insted of the "x"
y = -3/4(0) -6
y=0-6
y=6
So the y-intercept sould be placed in (0,-6)
That's what he did wrong when graphing the equation.

a triangle has side lengths 6,11 and 14. Is it acute, obtuse or right
Answer:
acute
Step-by-step explanation:
sorry if im wrong how I did it is on a paper or create a picture in your mind have a good night if you have a question please ask away in the comments
This triangle is obtuse.
What is right triangle?Triangle is defined as a triangle which one angle is a right angle or two sides are perpendicular.
Let a = 6 ,b = 11 & c = 14 be the sides of a traingle, c being longest of three
If a²+b²=c² it is right angled,
If a²+b²>c² it is acute,
If a²+b²<c² it is abtuse,
Substitue the values of a, b and c,
a²+b²= 6²+11² = 157
c² = 14² = 196
Since a²+b²<c²
Hence, this triangle is obtuse.

Kamal got married 5 years ago. Today his age is 1 1/4 times his age at the time of marriage. His sons age is 1/10 times his present age. What is hisson's age ?
Answer:Son's age =2.5 years old
Step-by-step explanation:
Step 1
Let the age of Kamla at marriage be represented as x
Age after five years = x+5
Given that today his age is 1 1/4 times his age at marriage, Our equation to express his age at marriage will be
x+ 5= (5/4)x
Multiplying 4 by both sides gives
4(x+5) = (5/4 x 4 )x
4x+20 = 5x
20=5x-4x
x= 20 years at Marriage
Therefore his present age = 20+5= 25
Step 2
Son' s age = 1/10 times his present age
Son's age = 1/10 x 25= 2.5 years old
Ms. Raab and Ms. Levy both drink coffee in the
mornings.
Ms. Raab adds 1 more teaspoon to each cup of
coffee than Ms. Levy. Together, they both add 5
teaspoons of sugar to their coffees.
How many teaspoons of sugar does Ms. Raab add?
How many teaspoons does Ms. Levy add?
Set up an equation to show this, and then solve.
Answer:
Ms Levy = 2
Ms Rabb = 3
Step-by-step explanation:
Let :
Number of teaspoons taken by Ms Levy = x
Number of teaspoons taken by Ms Rabb = x + 1
Total number of teaspoons taken by both = 5
(Number of teaspoons taken by Ms Rabb + Number of teaspoons taken by Ms Levy) = total number of teaspoons taken
x + 1 + x = 5
2x + 1 = 5
2x = 5 - 1
2x = 4
x = 4/2
x = 2
Hence,
Number of teaspoons of sugar added by Ms Levy = x = 2
Number of teaspoons of sugar added by Ms Rabb = x + 1 = 2 + 1 = 3
