Solve the system of equations by SUBSTITUTION
y=11+4x
3x+2y=0
Answer:
x=-2, y=3
Step-by-step explanation:
substitute 11 + 4x into the second equation for y
3x + 2(11+4x) =0
3x +22+8x=0
11x=-22
To solve for y: y=11+4(-2)
The relationship between x and y can be modeled by an inverse variation function equation

(Sorry i am not good at math) Write an expression for the operation described below.
multiply 10 by t
Answer:
Multiplying 10 by t will not work under most circumstances so it would be 10t which means 10*t but if you substitute the t for lets say 4 then you would get 40 but that wasn’t the question so your answer is 10t
f(x)=x^2-5x

From his house, Shane could drive due north to get to his parents' house or he could drive due east to get to his grandparents' house. It is 8 miles from Shane's house to his parents' house and a straight-line distance of 17 miles from his parents' house to his grandparents' house. How far is Shane from his grandparents' house?
Answer:
15 miles
Step-by-step explanation:
It is given that,
Shane could drive due north to get to his parents' house or he could drive due east to get to his grandparents' house.
It is 8 miles from Shane's house to his parents' house and a straight-line distance of 17 miles from his parents' house to his grandparents' house.
It can be calculated by considering a right angled triangle. Using pythagoras theorem, we can find the distance between Shane from his grandparents' house. Let it is d.
[tex]d^2=\sqrt{17^2-8^2} \\\\=15\ \text{miles}[/tex]
Hence, Shane is 15 miles from his grandparents' house.

Answer:
An equation for the parabola would be y²=-19x.
Since we have x=4.75 for the directrix, this tells us that the parabola's axis of symmetry runs parallel to the x-axis. This means we will use the standard form
(y-k)²=4p(x-h), where (h, k) is the vertex, (h+p, k) is the focus and x=h-p is the directrix.
Beginning with the directrix:
x=h-p=4.75
h-p=4.75
Since the vertex is at (0, 0), this means h=0 and k=0:
0-p=4.75
-p=4.75
p=-4.75
Substituting this into the standard form as well as our values for h and k we have:
(y-0)²=4(-4.75)(x-0)
y²=-19x

Bananas are curved because they grow towards the sun ☀️
Answer:
14776.8
Step-by-step explanation:
Yeahh its that because its the difference and the elevation for the death valley is below sea level so if you do
x-(-y) you essentially get x+y so therefore you add the two numbers and your good (x stands for that mountain and y is for the death valley
For f(x)= 2x-15 ,find f(x) when x=-4

The expressions that are equivalent to [tex]3\frac{1}{4} -(-\frac{5}{8} )[/tex] are
[tex]3\frac{1}{4} +(\frac{5}{8} ) \\\\3\frac{1}{4} +(+\frac{5}{8} )[/tex]
for understanding check the calcualtions here
Calculationan expression is the combination of numbers and operators like +, - * or /
If we have any equal sign then it is an equation .
Given expression is :
[tex]3\frac{1}{4} -(-\frac{5}{8} )[/tex]
to find out equivalent expression we remove the parentheisis by multiplying negative inside the parenthesis
Negative times negative becomes positive
first fraction is positive . So it remains the same
Multiply negative inside the parenthesis . Negative times negative is positive
so, the equivalent expressions are
[tex]3\frac{1}{4} +(\frac{5}{8} ) \\\\3\frac{1}{4} +(+\frac{5}{8} )[/tex]

Mose decides to launch a rocket out of the barn at Schrute farms. The equation below represents the height (in meters), of the rocket getting launched above the ground, t seconds after the rocket is launched. h(t) = -.4 (t - 2)^2 + 5 How high above the ground is the rocket before it is launched?
Height at an instance of time is given by :
h(t) = -4( t - 2 )² + 5 .....1
Differentiating above equation with respect to t .
[tex]\dfrac{dh}{dt}= -4\times ( -2 ) ( t - 2 ) \\\\\dfrac{dh}{dt}= 8(t-2)[/tex]
Now, for maximum , [tex]\dfrac{dh}{dt} = 0[/tex] .
8( t - 2 ) = 0
t = 2
Putting value of t = 2 in given equation, we get :
h( 2 ) = -4( 2 - 2 )² + 5
h( 2 ) = 5 m
Therefore, maximum height rocket can reach is 5 m.
