f(x)=x²+4x-7 determine the vertex
Answer:
The vertex of this parabola is [tex](-2,-11)[/tex]
Step-by-step explanation:
One way of finding the x-coordinate of the vertex of a parabola is by using the equation [tex]-\frac{b}{2a}[/tex]
From the function [tex]f(x)=x^2+4x-7[/tex], we can see that
[tex]a=1\\b=4\\c=-7[/tex]
This means that
[tex]-\frac{b}{2a}=-\frac{4}{2(1)} =-2[/tex]
So, the x-value of the vertex is -2. Now, we can plug this x-value into the function to find the y-coordinate of the point.
[tex]f(x)=x^2+4x-7\\\\f(-2)=(-2)^2+4(-2)-7\\\\f(-2)= 4-8-7\\\\f(-2)=-11[/tex]
Thus, the vertex of this parabola is [tex](-2,-11)[/tex]

Simplify and solve for X.
5(x + 20) = 7x + 30
Answer:
X = 35
Step-by-step explanation:
5 + 100 = 7x + 30
5x + 100 - 100 = 7x + 30 - 100
5x = 7x - 70
5x - 7x = 7x - 70 - 7x
-2x = -70
-2x/-2 = -70/-2
x = 35

James completely covered a square poster board using 68.2 inches with an exponent of 2.of cardstock. Which measurement is
closest to one side of the poster board in inches?
A) 34 in.
B) 8 in.
C) 6 in.
D) 30 in.
Answer:
A. 34in
Step-by-step explanation:
If James completely covered a square poster board using 68.2 inches with an exponent of 2, the the total perimeter of the square will be;
P = 2(68.2) = 136.4in
Since the perimeter of a square is expressed as:
P = 4L
136.4 = 4L
L = 136.4/4
L = 34.1in
Hence the measurement of one side of the square poster is closest to 34in

Find the slope of the line containing the pair of points.
(-9,- 8) and (-8,-6)
Answer:
slope = 2
Step-by-step explanation:
-8 - -6 / -9 - -8 = 2
Answer:
[tex]\frac{2}{1}[/tex] which is just 2
Step-by-step explanation:
slope = [tex]\frac{y2 - y1}{x2 - x1}[/tex]
So plug the numbers in, now it should look like [tex]\frac{-6 - (-8)}{-8 - (-9)}[/tex]
-6 - (-8) = 2
-8 - (-9) = 1
So the slope is [tex]\frac{2}{1}[/tex]
I think of a number, double it and subtract 1 and then square the answer. The result is 64. What could the number be?
If you doubled an unknown number and subtract 1 and then square the answer to get 64, the unknown number is 4.5.
Let the unknown number be n.Given the following data:
Output = 64To find an unknown number:
In this exercise, you're required to solve for an unknown number while performing some arithmetic operations such as multiplication, subtraction and square.
Translating the word problem into an algebraic expression, we have;
Doubling the unknown number, we would multiply by 2:
[tex]2n[/tex]
Subtracting 1 from the above and squaring, we have:
[tex](2n-1)^2 = 64\\\\2n-1=8\\\\2n =8+1\\\\2n=9\\\\n=\frac{9}{2}[/tex]
n = 4.5

Find a solution for the equation. Assume that all angles are a cute angles. tan(3Y +32) = cot(Y+32°)
9514 1404 393
Answer:
Y = 6.5°
Step-by-step explanation:
We know that tan(x) = cot(90°-x), so we could rewrite the equation as ...
cot(90 -(3Y+32)) = cot(Y+32)
58 -3Y = Y +32
26 = 4Y
6.5 = Y
One solution is Y = 6.5°.

The perimeter of a triangular garden is 72 feet. Find the length of the three sides if the middle length side is 4 feet greater than twice the length of the smallest side, and the longest side is 4 feet less than 3 times the length of the smallest side
Answer:
Smallest length side = 12 ft
Middle length side = 28 ft
Longest length side = 32 ft
Step-by-step explanation:
Perimeter of ∆ = sum of all its length sides
Thus, we are given that:
Perimeter = 72 ft
Let x represent the smallest length side. Therefore:
Smallest length side = x ft
Middle length side = (2x + 4) ft
Longest length side = (3x - 4) ft
Thus:
(2x + 4) + (3x - 4) + x = 72
Solve for x
2x + 4 + 3x - 4 + x = 72
Collect like terms
2x + 3x + x + 4 - 4 = 72
6x = 72
Divide both sides by 6
x = 72/6
x = 12
Find the length of all 3 sides by plugging in the value of x in each expression:
Smallest length side = x ft = 12 ft
Middle length side = (2x + 4) ft = (2(12) + 4) = 24 + 4 = 28 ft
Longest length side = (3x - 4) ft = (3(12) - 4) = (36 - 4) = 32 ft
