Answer:
A. (-3, 5.7)
Step-by-step explanation:
Inequalities help us to compare two unequal expressions. The ordered pair that satisfies the given inequality is (–3, 5.7).
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.
It is mostly denoted by the symbol <, >, ≤, and ≥.
The ordered pair that satisfies the given inequality is the solution set of the inequalities, the inequality can be written as,
[tex]4y^2+x-32y+68 > 0\\\\4y^2-32y+68 > -x[/tex]
Now, let's substitute the value of the first ordered pair, (–3, 5.7),
[tex]4(5.7)^2-32(5.7)+68 > -(-3)\\\\129.96-178.24+68 > 9\\\\19.72 > 9[/tex]
Since the inequality is satisfied the ordered pair is a set of solutions.
For the second ordered pair (-5.9,4),
[tex]4y^2-32y+68 > -x\\\\4(4)^2-32(4)+68 > -(-5.9)\\\\64-128+68 > 5.9\\\\4 > 5.9[/tex]
Since inequality is not true it is not the solution to the problem.
For the third ordered pair (-8, 5),
[tex]4y^2-32y+68 > -x\\\\4(5)^2-32(5)+68 > -(-8)\\\\64-128+68 > 8\\\\8 > 8[/tex]
Since inequality is not true it is not the solution to the problem.
For the fourth ordered pair (-13, 3),
[tex]4y^2-32y+68 > -x\\\\4(3)^2-32(3)+68 > -(-13)\\\\64-128+68 > 13\\\\8 > 13[/tex]
Since inequality is not true it is not the solution to the problem.

Which graph shows the zeros of the function f(x) = 2x2 + 4x – 6 correctly?
Answer:
Divide through by 2 .
x2 - 2x - 3 = 0 What two numbers add to -2 and multiply to -3 ? → +1 and -3
So...we can factor it like this...
(x + 1)(x - 3) = 0 Set each factor equal to zero and solve for x.
x + 1 = 0 and x - 3 = 0
x = -1 and x = 3

Circle A has center of (6, 7), and a radius of 4 and circle B has a center of (2, 4), and a radius of 16.
Answer:
See solutions below
Explanation
We are to find the equation of circle A and B
The equation of a circle is expressed as;
(x-a)^2 + (y-b)^2 = r^2
(a, b) is the centre and r is the radius
For Circle A that has center of (6, 7), and a radius of 4
Substitute;
(x-6)^2 + (y-7)^2 = 4^2
(x-6)^2+(y-7)^2 = 16
Hence the equation of circle A is (x-6)^2+(y-7)^2 = 16
For circle B:
If circle B has a center of (2, 4), and a radius of 16
The equation is expressed as;
(x-2)^2+(x-4)^2 = 16^2
(x-2)^2+(x-4)^2 = 256
Hence the required equation is (x-2)^2+(x-4)^2 = 256

lucy works for 37 hours per week. her weekly wage is £303.40. she receives a pay increase of 25p per hour. work out her new weekly wage
Answer:
312.65
Step-by-step explanation:
The new weekly wage is $312.65 if the Lucy works for 37 hours per week. Her weekly wage is £303.40.
What is linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
Lucy works for 37 hours per week.
Weekly wage = $303.40
Per hour wage = 303.40/37 = $8.2 per hour
1 dollar = 100 penny(p)
25p = $0.25
New wage per hour = 8.2 + 0.25 = $8.45
Total wage = 8.45×37 = $312.65
Thus, the new weekly wage is $312.65 if the Lucy works for 37 hours per week. Her weekly wage is £303.40.

Determine the are of the triangle
Answer:
25m
Step-by-step explanation:
The unit not to be used to find the triangle area is 25 because it is the hypotenuse and to find the area of a triangle you only need base and height. The base would be 24.6 and the height would be 7.3, which would both be needed in the equation.

The cost of renting ice skates at a skating is $1.25. The rink charges $3.25 for each hour, x, of skating. Which graph best models this situation, where y is the total cost to go skating?
Answer:
Step-by-step explanation:
y = 3.25x + 1.25
1.25 is y-intercept
3.25 is the slope of a graph.
If x = 0, then y = 1.25
(0, 1.25)
If x = 3, then y = 3.25(3) + 1.25 = 11

1. Find the slope and the y-intercept
of the graph of the linear equation.
y = -7x + 2
A) slope: -3; y-intercept: 2
1
B) slope: 2; y-intercept: -7
C) slope: -7; y-intercept: 2
D) slope: 2; y-intercept: -7
Answer:
c) slope: -7 ; y-intercept: 2
Step-by-step explanation:
Note the slope intercept form:
y = mx + b
y = (x , y)
m = slope
x = (x , y)
b = y-intercept
Note in this case:
y = (-7)x + 2
y = y
m = -7
x = x
b = 2
c) slope: -7 ; y-intercept: 2 is your answer.

A quadratic function is represented by the graph. (graph below.) (do a-d.)
(a) What is the equation of the axis of symmetry of the function?
(b) What are the coordinates of the vertex of the function?
(c) What are the coordinates of the x-intercepts of the function?
(d) What are the coordinates of the y-intercept of the function?
Answer:
The axis of symmetry is x=1
The vertex is (1,-9)
The x-intercepts are (4,0) and (-2,0)
The y-intercept is (0,-8)
Step-by-step explanation:
axis of symmetry is the line where the vertex is, so in the quadratic of x^2, the axis of symmetry would be zero because half of the equation is on one side and the other half on the other side
The vertex is the lowest point on the quadratic, on the y values
the x-intercepts are the places the graph intercepts the x-axis.
The y-intercepts are the places the graph intercepts the y-axis

If the Quadratic functions for the equations are graphed, which is the widest?
A. y = x^2
B. y = 2x^2
C. y = 6x^2
D. y = 1/4x^2
y = ax^2
If the absolute value of a is <1 the graph is wider than when a = 1
If the absolute value of a is >1 the graph is narrow than when a = 1
The only function that fits that description is
y = 2x^2

How many moles contain 1.25x 10^15 molecules of glucose
Answer:
i.e. mass of 1 mole of glucose, C6H12O6 = (6 × 12.01 + 12 × 1.01 + 6 × 16.00) g = 180.18 g (using atomic weight data to 2 decimals) 1 mole of carbon atoms weighs 12.01 g and there are 6 moles of C atoms in 1 mole of glucose, so the mass of carbon in 1 mole of glucose = 6 × 12.01 g = 72.06 g.

2) UPS charges $7 for the first pound, and $0.20 for each additional pound. FedEx charges $5 for the first pound, and $0.30 for each additional pound. How many pounds, p, will it take for UPS and FedEx to cost the same?
Answer:
Step-by-step explanation:
300×1.035⁵ ≅ $356.31
:::::
UPS charge = 7 + (p-1)0.20 = 0.20p +6.80
FedEx charge = 5 + (p-1)0.30 = 0.30p + 4.70
0.30p + 4.70 = 0.20p +6.80
0.10p = 2.1
p = 21
They charge the same for 21 pounds.
