Answer:
pretty sure ypu arent suppose to send your entire math homework like this
how do you solve this problem
Answer:
(-6,1)
Step-by-step explanation:
-x + y = 7 [Equation (1)]
2x + 5y = -7 [Equation (2)]
Multiplying equation (1) by 5, to make the coefficients of y equal in both equations.
5(-x + y) = 5(7)
=> -5x + 5y = 35 [Equation (3)]
Subtracting equation (3) from equation (2).
(2x + 5y) - (-5x + 5y) = -7 - 35
=> 2x + 5y + 5x - 5y = -7 - 35
=> 7x = -42
=> x = -42/7
=> x = -6
Putting the value of x in equation (1).
-(-6) + y = 7
=> 6 + y = 7
=> y = 7 - 6
=> y = 1
So, x = -6 and y = 1.

Suppose that NOP is isosceles with base.
Suppose also that and.
Find the degree measure of each angle in the triangle.
Step-by-step explanation:
In isocseles triangle, base angles are equal :
base angles are angle N and angle P:
angle N=angle P
3x+17=4x+2
4x-3x=17-2
x=15
For angle N:
subtitute x in angle N
=3(15)+17
=45+17
=62
For angle P:
subtitute x in angle P:
=4(15)+2
=60+2
=62
For angle O:
sum of all angles in a triangle is 180.
angle N +angle P+angle O=180
62+62+angle O=180
angle O=180-62-62
angle O=56

A soda company had sales of $35,107 million in 2010 and $45,984 million in 2014. Use the Midpoint Formula to estimate the sales in 2012. Assume that the sales followed a linear
pattern.
$ __ million
Answer:
40545.50 mill
Step-by-step explanation:
so the average rate from 2010 to 2014 is a change of 4 years with a increase of 2719.25 milllion per year so if that rate started at the 2010 value (35107 million) then if you add the average rate twice you get how much they would of made in 2012 so 35107 plus 2719.25 plus 2719.25 you get 40545.50 million so that the answer oh yea and its like a 5 million pattern over 2 years that why average rate is 2.5ish

If helpful, brainliest please !
Answer and Step-by-step explanation:
If you're confused by what this expression means by looking at it, then try writing or saying out loud the expression.
Two minus negative 6. (2 - (-6))
We know from math that when two negative numbers multiply together, they result in a positive.
We have here the negative 1 (represented as just -, because it isn't necessary to include 1 in the expression) multiply the negative 6.
-1 * -6 = +6.
Now we have the expression 2 + 6.
Add them together.
2 + 6 =
8
8 is the answer.

Find the largest prime factor of 18! + 19! + 20!
18! is common to each term in the sum:
18! + 19! + 20! = 18! (1 + 19 + 19×20) = 18!×400
The largest prime factor of 18! is of course 17.
Meanwhile,
400 = 16×25 = 2⁴×5²
so the largest prime factor of 18! + 19! + 20! is 17.

an angle measures 15 degrees more than its complement. Find the measures of the two angles
Answer:
The first angle is 37.5° and the second would be 52.5°
Step-by-step explanation:
Angles are complementary when their sums add up to 90°.
[tex]x+(x+15) = 90\\x+x+15=90\\x+x=75\\x=37.5[/tex]
The first angle is 37.5° and the second would be 52.5°, after we plug in x.
Have a nice day. Feel free to ask questions. Spread The Love.
Answer:
Angle 1 = x = 37.5°Angle 2 = x + 15 = 52.5°Concept:
Here, we need to know the idea of the complementary angle.
Two angles are said to be complementary if they add up to 90 degrees.
Be aware that three or more angles cannot be complementary even if their sum is 90 degrees.
Solve:
Given information
Angle 1 = x
Angle 2 = x + 15
Given expression deducted from the definition of the complementary angle
Angle 1 + Angle 2 = 90
Substitute values into the expression
(x) + (x + 15) = 90
Combine like terms
(x + x) + 15 = 90
2x + 15 = 90
Subtract 15 on both sides
2x + 15 - 15 = 90 - 15
2x = 75
Divide 2 on both sides
2x / x = 75 / 2
[tex]\boxed{x=37.5}[/tex]
Find the measure of angle 2
Angle 2 = x + 15 ⇔ Given expression
Angle 2 = (37.5) + 15 ⇔ Substitute values into the expression
Angle 2 = [tex]\boxed{52.5}[/tex] ⇔ Simplify by addition
Hope this helps!! :)

A ball is thrown into the air with an upward velocity of 80 feet per second. The function
h = -16t2 + 80t models the height h, in feet, of the ball at time t, in seconds. When will the ball reach the ground?
after 3 seconds
after 4 seconds
after 5 seconds
after 6 seconds
Best explanation gets Brainliest!!
Answer:
After 5 seconds
Step-by-step explanation:
One is given the following expression to model to the flight path of a ball:
[tex]h=-16t^2+80t[/tex]
In this problem, one is asked to find the time at which the ball lands on the ground. The easiest way to do so is to factor the expression. Take out factors that both terms have in common. The one will set the equation equal to zero, as this is the height at which one wants to find the time for. Finally, use the zero product property to solve. The zero product property states that any number times zero equals zero. Apply these ideas to the given function:
[tex]h=-16t^2+80t[/tex]
Factor the expression; both terms have a common factor of (-16t):
[tex]h=-16t^2+80t[/tex]
[tex]h=-16t(t-5)[/tex]
Set the equation equal to zero to solve for when the ball has a height of zero or rather lands on the ground:
[tex]h=-16t(t-5)[/tex]
[tex]0=-16t(t-5)[/tex]
Now use the zero product property, this states that any number times zero equals zero. Set each of the factors equal to zero, and solve to find the value of (t) for which the factor will equal zero:
[tex]0=-16t(t-5)[/tex]
[tex]0=-16t[/tex] [tex]t - 5 =0[/tex]
Solve for the value (t) using inverse operations,
[tex]0=-16t[/tex] [tex]t - 5 =0[/tex]
(divide by (-16) (add (5))
[tex]0=t[/tex] [tex]t=5[/tex]
As one can see, the ball started on the ground, therefore at (0) seconds, its height was (0). Then, after (5) seconds the ball landed on the ground, therefore, after (5) seconds its height was again (0).
