x = years
9x-6x = 16-7
3x = 9
x = 3
That means the tree will grow three feet per year.
if x+y=3, x²+y²=5 then find the value of xy
Answer:
[tex]\huge\boxed{xy = 2}[/tex]
Step-by-step explanation:
=> [tex]\sf (x+y)^2 = x^2 + y^2 + 2xy[/tex]
Given that [tex]\sf x + y = 3 , x^2 + y^2 = 5[/tex]
=> [tex]\sf (3)^2 = 5 + 2xy[/tex]
=> [tex]9 = 5 + 2xy[/tex]
=> [tex]9-5 = 2xy[/tex]
=> [tex]4 = 2xy[/tex]
Dividing both sides by 2
=> 2 = xy
OR
=> xy = 2

Find the slope of the line shown
Answer: m= -1/2
Step-by-step explanation:
m is the gradient of a line. and the formula for gradient is (y2-y1)/(x2-x1)
first, find a point on the line, (-2,1) and that is equal to (x1,y1)
then find another point on the line, (2,-1) and that is equal to (x2,y2)
then substitute your points into the formula above and that is equal to
(-1-1)/(2-(-2))
= -2/4
= -1/2
that is your answer

is /62 rational or irrational
Answer:
yes it is rational
Step-by-step explanation:
it is rational because if 62 can be expressed as a ratio, then a quotient is the result you get when you divide one number by another number. For 62 to be a rational number, the quotient of two integers must equal 62. it can be expressed as a fraction in the form 62/1
Find the value of y if EF = EG.
Answer:
55°Step-by-step explanation:
The question lacks appropriate diagram. Find the diagram in the attachment.
From the diagram, it can be seen that the triangle is an isosceles triangle because two of its sides are parallel (i.e the same). Since two of the sides are the same, hence the two base angles will be the same.
From the diagram, <EFG = <EGF
Since <EFG = 55° hence <EGF = y = 55°
Hence the va;ue of y is 55°
The measure of an angle is 6° less than the measure of its complement. Write and solve an algebraic equation to find the measure of each angle. I need help!
Answer:
2x + 6 = 90
Step-by-step explanation:
Complementary angles are angles that add up to 90 degrees, so the sum of the angles is 90 degrees. We could let x be the measure of the angle. The other angle is x + 6, so the answer is x + x + 6 = 90, or 2x + 6 = 90
From the given measure whose angle is 6° less than the measure of its complement.
The measure of the two angles is 47° and 43° respectively.
Complementary angles are angles whose sum is equal to 90°. It is usually composed of two angles complementing themselves.
Mathematically;
Let the first angle be a and the second angle be b
∴
a + b = 90° (complemntary angles)
If one of the angles is 6° less than its complement;
i.e.
Let a = 6
SO, the algebraic equation for the value of a is:
a = b - 6
Replacing the value of a to solve the equation, we have:
(b - 6) + b = 90
2b - 6 = 90
2b = 90 - 6
2b = 86
b = 86/2
b = 43°
From a + b = 90°
a = 90° - 43°
a = 47°
Therefore, we can conclude that the measure of each angle is 47° and 43°.

How do you know if a given relation is a function or not a function?
Answer:
In general, a relationship f (x) = y is a function only if, for each value of x that you plug into it, you get only one value for y.
Step-by-step explanation:
Sometimes the only way to tell if a given relationship is a function or not is to try various values for x to see if they yield unique values for y.

Max's grandparents have $6000 that they want to give to him and his brother Sam. They like Sam more than Max, so they plan to give Sam 4 times the amount they will give Max. Determine the amount of money that Sam will get. Sam's Amount=$
Answer: Same will get $4800
Step-by-step explanation:
If Sam will get 4 times the amount of money they will give Max then we can come up with the equation s = 4m where s is the amount that same get and m is the amount that Max will get.
And we know that if they combine their money they will have $6000 in total so we can also come up the equation s + m = 6000
So using the equation
s= 4m and s+m=6000 substitute the value of x into the second equation and sole for m ..
4m + m = 6000
5m = 6000
m = 1200
So we know that Max will get $1200 and Sam will get 4 times as much as that.
s= 4(1200)
s = 4800
square root of 1000 (simplified)
Answer:
10 √10
Step-by-step explanation:
Answer:
[tex]10\sqrt{10}[/tex]
Step-by-step explanation:
The largest perfect square of the factors of 1000 is 100. We can therefore convert √1000 like this:
√100 × 10
Next, we separate the numbers inside the √ as such:
√100 × √10
√100 is a perfect square that equals 10. We can therefore put 10 outside the radical and get the final answer to square root of 1000 in simplest radical form as follows:
10√10

A researcher needs 60 L of 50% concentrate solution for a certain experiment, but she has only 30% solution and 70% solution. How many liters of the 30% and the 70% solutions should she mix to get what she needs?
Answer:
30 liters of 30% solution and 30 liters of 70% of solution should be mixed by the researcher to get 60 liters of 50% solution.
Step-by-step explanation:
Let 'x' liters of 30% solution and 'y' liters of 70% solution are added together to get the required 60 liters of 50% of the solution.
According to the question, 30% solution and 70% solution are mixed and so, we get
[tex]0.3x+0.7y=0.5 \cdot 60\\\Rightarrow 0.3x+0.7y=30----(1)[/tex]
Also, sum of the final solution should be 60 liters only so, we get
[tex]x+y=60----(2)[/tex]
Solving equations (1) and (2), we get
[tex]x=30 liters\\ y=30 liters[/tex]
Hence, we can say that 30 liters of 30% solution and 30 liters of 70% of solution should be mixed by the researcher to get 60 liters of 50% solution.

h^2 + 11h +18. The factored expression is
Answer:
(h+9)⋅(h+2)
Step-by-step explanation:
1.1 Factoring h2+11h+18
The first term is, h2 its coefficient is 1 .
The middle term is, +11h its coefficient is 11 .
The last term, "the constant", is +18
Step-1 : Multiply the coefficient of the first term by the constant 1 • 18 = 18
Step-2 : Find two factors of 18 whose sum equals the coefficient of the middle term, which is 11 . -18 + -1 = -19
-9 + -2 = -11
-6 + -3 = -9
-3 + -6 = -9
-2 + -9 = -11
-1 + -18 = -19
1 + 18 = 19
2 + 9 = 11 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 2 and 9
h2 + 2h + 9h + 18
Step-4 : Add up the first 2 terms, pulling out like factors :
h • (h+2)
Add up the last 2 terms, pulling out common factors :
9 • (h+2)
Step-5 : Add up the four terms of step 4 :
(h+9) • (h+2)
Which is the desired factorization
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{(h + 9)(h + 2)}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{ {h}^{2} + 11h + 18}[/tex]
Here, we have to find out two numbers that adds to 11 and multiplies to 18
[tex] \dashrightarrow{ \sf{ {h}^{2} + (9 + 2)h + 18}}[/tex]
Distribute h through the parentheses
[tex] \dashrightarrow{ \sf{ {h}^{2} + 9h + 2h + 18}}[/tex]
Take h as common. Similarly, take 2 as common
[tex] \dashrightarrow{ \sf{h(h + 9) + 2(h + 9)}}[/tex]
[tex] \dashrightarrow{ \sf{(h + 9)(h + 2)}}[/tex]
