7/2x+7y=14 solve with substitution
9514 1404 393
Answer:
(x, y) = (-1, 5/2)
Step-by-step explanation:
The only variable with a coefficient that has a magnitude of 1 is x in the first equation. Using that equation, we can write an expression for x:
x = 2y -6
This can be substituted for x in the second equation.
(7/2)(2y -6) +7y = 14
7y -21 +7y = 14 . . . . . . eliminate parentheses
14y = 35 . . . . . . . . . . . add 21
y = 35/14 = 5/2 . . . . . divide by the coefficient of y
x = 2(5/2) -6 = -1
The solution is (x, y) = (-1, 5/2).
The legs of a right triangle measure 10 feet and 24 feet. What is the length of the hypotenuse, in
feet?
A. 27
B. 26
C. 34
D. 71,644
E. 48
Answer:26
Step-by-step explanation:
a squared+b squared= the hypotenuse squared
Input
10 squared+24 squared=the hypotenuse squared
100+576=676 squared
Now we need to find the square route of 676 because this is the hypotenuse squared, and we need to find the hypotenuse. And the square route of 676 is 26.

What is the area of the triangle shown below?
A. 84 sq. units
B. 42 sq. units
C. 20 sq. units
D. 10 sq. units
Answer:
42 sq. Units
Step-by-step explanation:
I took the test
The area of the triangle shown below is B. 42 sq. units, the correct option is B.
What is the area of a triangle?The area of the triangle is defined as the product of half the base and the height of the triangle.
We are given the parameters are;
Length of its base = b units
Its height = h units long,
Then we get:
Area of a triangle = 1/2 b h
We are given that;
Base= 14, Height= 6
Now,
The area of a right triangle is given by:
Area = (1/2) * base * height
Substituting the values;
Area = (1/2) * 14 * 6
= 42 square units
Therefore, the area of triangle will be 42 sq. units.

The points (0,-14), (1,-3), (2,0), (3,5) are on a parabola. Write the function to represent this parabola.
Answer:
y= -4x^2 + 15x - 14
Step-by-step explanation:
A parabola is always in the form y = ax^2 + bx + c.
Substitute each point to produce different equations:
-14 = 0a + 0b + c = c
so c = -14
-3 = a1^2 + b1 + c = a + b - 14
so a + b = 11
0 = a2^2 + b2 + c = 4a + 2b -14 = 0
so 4a + 2b = 14
if we double a + b = 11 we get 2a + 2b = 22
Subtract this from 4a + 2b = 14 and we get 2a = -8 so a= -4 and b = 11 - a = 15
We don't need to use the (3,5) points as we have all the information we need.

Answer:

Step-by-step explanation:
[tex]x^4+11x^2=3x^2+128[/tex]
First, we subtract 128 from both sides:
[tex]x^4+11x^2-128=3x^2[/tex]
Then, we subtract [tex]3x^2[/tex] from both sides:
[tex]x^4+8x^2-128=0[/tex]
Rewrite the equation:

[tex]u^2+8u-128=0\\u=8,u=-16\\x^2=8:x=2\sqrt{2},x= -2\sqrt{2} \\x^2=-16:x=4i,x=-4i[/tex]

I forgot how to find a function in a graph
Answer:
This graph is NOT a function.
Step-by-step explanation:
A graph is a function only if there is exactly one y-value for every x-value. In this case, there are many x-values that have two y-values, making this graph not a function.

PLZ help me ASAP! ( I NEED HELP WITH PART C THE EXPLANATION)
Let x and y be the two numbers. Let's say that either x = y or x < y. To keep things relatively simple, we'll make both of these numbers positive.
We are told that they add to 50, so
x+y = 50
which solves to
y = 50-x
Their product is
x*y = x*(y) = x*(50-x) = 50x - x^2 = -x^2 + 50x
So the function
f(x) = -x^2 + 50x
will give us the product f(x) for the input x. Keep in mind that if we know what x is, then y = 50-x is used to find y.
The function f(x) graphs out a parabola that opens downward. Check out the diagram below. This means the very peak point of the parabola is what we're after. This is the vertex. At the vertex, we'll have f(x) maxed out as much as possible. This occurs at the point (25,625) meaning x = 25 and y = 50-x = 50-25 = 25 both multiply to x*y = 25*25 = 625, which is the largest possible product.
In short, this provides a visual means to confirm you have the correct answers for part b.
The maximum distance (in nautical miles) that a radio transmitter signal can be sent is represented by the expression 1.23√h , where h is the height (in feet) above the transmitter.
Estimate the maximum distance x (in nautical miles) between the plane that is receiving the signal and the transmitter. Round your answer to the nearest tenth.
Answer:
182.4 nautical milesStep-by-step explanation:
Given
x = 1.23√hh = 22000 ftSubstitute h and find the value of x:
x = 1.23√22000 = 182.4 nautical miles (rounded)2(x-5)=8x+14-2X

A. x < -1 and x 24
B. x>-1 and x 34
C. -13x34
D. -13x<4
Answer:
B
Step-by-step explanation:
there is a hole at -1, so -1 is less than x and x is greater than or equal to 4
The compound inequality shown on the graph is x < -1 and x≥4.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
We have the graph for the inequality.
The first part of the inequality is
x < -1
and, the second part of inequality x≥4
So, the compound inequality is x < -1 and x≥4.
