WHATS X AND Y??
Y = 3x+ 4 and 2x – 4y = -6
Answer:
X=-1, y=1
Step-by-step explanation:
Substitute value of y in first equation (3x+4) with y of second equation.
2x-4(3x+4)=-6
2x-12x-16=-6
-10x=10x=-1
solve for y but putting -1 for x value in either equation
y=3(-1)+4
y=-3+4
y=1
Write the equation in slope-intercept form m=-5 b = 7
Answer:
y = -5x + 7
Step-by-step explanation:
y = mx + b
where, m = -5 and b = 7
y = (-5)x + 7
y = -5x + 7
Thus, Option b is correct

Answer:
y = -4/3x +23/2
Step-by-step explanation:
The tangent of interest is perpendicular to the radius at the given point on the circle. To find the perpendicular, it helps to know the slope of the radius segment. To find that, we need the center of the circle.
The center of the circle can be found by completing the square for each variable.
(x^2 -2x) +(y^2 +4y) = 20
(x^2 -2x +1) +(y^2 +4y +4) = 20 +1 +4
(x -1)^2 +(y +2)^2 = 25
Comparing this equation to the standard form equation for a circle, we can find the center.
(x -h)^2 +(y -k)^2 = r^2 . . . . . . . circle of radius r centered at (h, k)
The center of circle P is (1, -2).
__
The slope m' of the line segment between (1, -2) and (5, 1) is given by ...
m' = (y2 -y1)/(x2 -x1)
m' = (1 -(-2))/(5 -1) = 3/4
The slope m of the perpendicular line is the opposite reciprocal of this, so is ...
m = -1/m' = -1/(3/4) = -4/3
The y-intercept of the desired line can be found from ...
b = y -mx . . . . . . . for m=-4/3 and (x, y) = (5, 1)
b = 1 -(-4/3)(5) = 23/3
Then the equation of tangent line AB is ...
y = mx +b
y = -4/3x +23/3

NOT the first one cause 8 isn't the total. Don't think it would be the last one cause that's no fun. So it's either the second or the third one. The third one also makes no sense cause it only includes the returns from yesterday. I'm going with the second one

ASAPPP! An arrow is shot into the air. A function representing the relationship between the number of
seconds it is in the air, t, and the height of the arrow in feet, h, is given by the equation below.
What is the initial height of the arrow?
h(t) = -16t^2+ 128t + 1.5
Answer:
The initial height of the arrow is 1.5 feet above the ground.
Step-by-step explanation:
Let be the height of the arrow be represented by the function [tex]h(t) = -16\cdot t^{2}+128\cdot t + 1.5[/tex], where [tex]h(t)[/tex] is the current height of the arrow, measured in feet, and [tex]t[/tex], is the time, measured in seconds.
Mathematically speaking, the initial height is the value of [tex]h[/tex] evaluated at [tex]t = 0\,s[/tex]. That is:
[tex]h(0) = -16\cdot (0)^{2}+128\cdot (0) + 1.5[/tex]
[tex]h(0) = 1.5\,ft[/tex]
The initial height of the arrow is 1.5 feet above the ground.
is 0.000061 greater than 610,000
Answer:
no.
Step-by-step explanation:
0.000061 is a decimal, and the number to the left of the decimal would be a whole number, which is 0. this means the number is less than one.. while 610,000 is a number jn the thousands, making it greater.
Answer:
No
Step-by-step explanation: 610,000 is greater than 0.000061 because 0.000061 is a decimal in the 100,000ths place.

Where are the minimum and maximum values for f(x)=−2+4cosx on the interval [0,2π]?
Answer:
[tex]f(x) = - 2 + 4 \cos(x) \\ for \: minimum \: \: x = 0 \\ f(0) = - 2 + 4 \cos(0) \\ minimum \: value = 2 \\ for \: maximum \: value \: \: x = 2\pi \\ f(2\pi) = - 2 + 4 \cos(2\pi) \\ maximum \: value = - 2[/tex]
The function is minimum at 3π/2 and the function is maximum at 0 and 2π.
What is the maximum and minimum value of the function?The condition for the maximum will be
f(x)'' < 0
The condition for the minimum will be
f(x)'' > 0
The function is given below.
f(x) = −2 + 4cosx
Differentiate the function with respect to x, then we have
f'(x) = − 4 sin x
Again differentiate the function with respect to x, then we have
f''(x) = − 4 cos x
Then the minimum value of the function will be
f'(x) = 0
−4 sin x = 0
sin x = 0
The value of f''(x) is positive in the interval of (π/2, 3π/2). Then the value of x will be
x = π
Then the maximum value of the function will be
And the of f''(x) is negative in the interval of [0,2π] – (π/2, 3π/2). Then the value of x will be
x = 0 and 2π
More about the maximum and minimum value of the function link is given below.

Quadrilateral ABCD is similar to quadrilateral EFGH. Find the measure of side EF
Answer:
EF = 6.6
Step-by-step explanation:
Since ABCD is similar to EFGH, then EH is similar to AD. So, we can solve by first dividing 12 by 2 (EH by AD). The quotient of this is 6. This tells us that quadrilateral EFGH is 6 times larger than quadrilateral ABCD, since they are similar. So, with this and the measurement of AB (which is similar to EF), we can now solve for EF. We simply multiply 1.1 (the measurement of AB) by 6 (how many times larger EFGH is compared to ABCD). The product of this is 6.6, our final answer.
The grade seven students are showing a movie in their school auditorium to raise money for the end of year field trip. Goal is to raise at least $500. Each ticket sales for $16. So far they have sold 20 tickets. Which inequality graph correctly shows how many more tickets they need to sell to reach their goal.
Answer:
The answer is A because it needs to be a filled dot to represent the information correctly. 16 x 20 is 320 so they need 180 more to have at least 500 dollars which is 11.25 tickets but you cant have a fourth of a ticket so you need atleast 12 tickets sold.

1. Minh asks Marco to duplicate a graphic she has on her restaurant’s ceiling. The ceiling is covered with 1 ft by 1 ft tiles. A chandelier hangs in the center of the ceiling. The graphic Minh painted on the ceiling is a pentagon. Assuming that the chandelier is located at , the pentagon’s coordinates are . Minh wants to have the same graphic design duplicated in another location on the ceiling. She is considering four ideas.
