Consider the equation 2(3x + 4) = ax + b
Part 1
Find one value for a and one value for b so that the equation has infinitely many solutions.
For the value of a you determined above what is the value for b so that the equation has infinitely many solutions
Support your answer. Explain your reasoning
Part 2
Find one value for a and one value for b so that the equation has no solution.
Find the value of a you determined above what is the value for b so that the equation has no solution.
Support your answer explain your reasoning.
Answers
Answer:
Let's solve for a.
2(3x+4)=ax+b
Step 1: Flip the equation.
ax+b=6x+8
Step 2: Add -b to both sides.
ax+b+−b=6x+8+−b
ax=−b+6x+8
Step 3: Divide both sides by x.
ax
x
=
−b+6x+8
x
a=
−b+6x+8
x

As an estimation we are told €4 is $5. What is the conversion rate from € to $? Give your answer rounded to 2 DP.
Answers
Answer:
$1.25/€
Step-by-step explanation:
€4 = $5
Divide both sides by €4.
€4/€4 = $5/€4
1 = $5/€4 = $1.25/€
Since $1.25/€ is equal to one, multiplying a number of euros by it will not change the value of the number. It will convert it from euros to dollars.
Answer: $1.25/€
The manufacturer of official NFL footballs uses a machine to inflate its new balls to a pressure of 13.5 pounds. When the machine is properly calibrated , the mean inflation pressure is 13.5 pounds, but uncontrollable factors cause the pressures of individual footballs to vary randomly from 13.3 to 13.7 pounds. For quality control purposes, the manufacturer wishes to estimate the mean inflation pressure to within 0.025 pound of its true value with a 99% confidence interval. What sample size should be used
Answers
Answer:
106
Step-by-step explanation:
Given that:
Mean (m) = 13.5 pounds
Error margin = 0.025
α = 99%
Variation interval = range = 13.3 to 13.7
Standard deviation (σ) estimate from range :
Range / 4
(13.7 - 13.3) /4
= 0.4 / 4
= 0.1
Zcritical at 99% = 2.576
Using the formula :
Sample size (n) = [ (Zcritical * σ) / M. E]^2
n = [(2.576 * 0.1) / 0.025]^2
n = (0.2576 / 0.025)
n = 10.304^2
n = 106.172
n = 107 samples
Axis of symmetry: x = -0.5; Vertex: (-0.5, 0.75); f(x) = x2 + x + 1
Axis of symmetry: x = -0.5; Vertex: (-0.5, -0.75); f(x) = x2 - x + 1
Axis of symmetry: x = -0.5; Vertex: (-0.5, 0.75); f(x) = -x2 + x
Axis of symmetry: x = -0.5; Vertex: (-0.5, 0.75); f(x) = x2 + 2x + 1
Answers
Graph of the question is missing so I have attached it
Answer:
Option A: Axis of symmetry: x = -0.5; Vertex: (-0.5, 0.75); f(x) = x2 + x + 1
Step-by-step explanation:
1) The axis of symmetry of quadratic graph is the vertical line that divides the graph curve into two congruent halves. In this case, it is: x = -0.5
2) Vertex is the point at which the graph curve changes direction or simply coordinates of the crest or trough of the curve.
The graph given has a trough with the coordinates: x = -0.5, y = 0.75. This is (-0.5, 0.75)
3) The roots of a quadratic equation are the points where the curve crosses the x-axis. In this case, it doesn't cross and so we have imaginary roots.
Now, formula for line of symmetry is; x = -b/2a
Thus; -b/2a = -0.5 or -b/2a = -1/2
Thus, b = 1 and a = 1
Our first and second terms will now be;
x² + x
Looking at the options, the only one with x² + x as it's first 2 terms is option A.
Thus, the complete equation will be x² + x + 1

Step-by-step explanation:
d = n^2 - 12n + 43
d = 30
30 = n^2 - 12n + 43
0 = n^2 - 12n + 13
now solve for n using quadratic formula:
a=1, b=-12, c=13
n = (-b +- sqrt( b^2 -4ac))/2a
two answers ( one for + the square root, one for - the square root)
n = 1.20, n = 10.8

[tex]\boxed{x = 4~~and~~ y = -6}[/tex]
.
Step-by-step explanation:
-7x - 4y = -4 (times 5) -35x - 20y = -20
-9x - 5y = -6 (times 4) -36x - 20y = -24
.
Eliminate both equations
[tex]-35x - 20y = -20[/tex]
-36x - 20y = -24
[tex]x = 4[/tex]
.
Substitute the value of x to one of equations
[tex]-7x - 4y = -4[/tex]
[tex]-7(4) - 4y = -4[/tex]
