write an equation in slope intercept form, passes through (-1,-10), parallel to y=7
An equation in slope intercept form, passes through (-1,-10), parallel to y=7 is y = -10 .
What is slope?The slope of a line is defined as the change in y coordinate with respect to the change in x coordinate of that line. The slope of a line is the measure of the steepness and the direction of the line.
What is standard form of slope for line and point ?The slope intercept formula y = mx + b is used when you know the slope of the line to be examined and the point given is also the y intercept (0, b). In the formula, b represents the y value of the y intercept point.
According to the question
An equation in slope intercept form,
passes through (-1,-10), parallel to y = 7
now,
When line is y = 7
that means , x = 0
and it is also a horizontal line , i.e slope (m) = 0
As, Parallel lines have same slope .
By using slope intercept formula for (-1,-10)
y = mx + b
substituting the value
-10 = 0 + b
b = -10
Therefore, putting values in general equation of slope intercept for any point
y = mx + b
y = -10
Hence, an equation in slope intercept form, passes through (-1,-10), parallel to y=7 is y = -10 .

Part A: Write a system of equations that can be solved to find the number of packets of strawberry wafers and the number of packets of chocolate wafers that Devon and his friends bought at the carnival. Define the variables used in the equations. (5 points)
Part B: How many packets of chocolate wafers and strawberry wafers did they buy? Explain how you got the answer and why you selected a particular method to get the answer. (5 points)
A)
S = Strawberry wafer packets
c = chocolate wafer packets
s +c = 22
3.00s +1.00c = 30.00
B)
s + c = 22
s = 22-c
3.00(22-c) + 1.00c = 30.00
66.00 - 3.00c +1.00c = 30.00
66.00 -2.00c =30.00
-2.00c = -36.00
c = -36.00 / -2.00 = 18

Using complete sentences, explain how to find the minimum value for each function and determine which function has the smallest minimum y-value. G(x) = 2 sin (x-π) F(x) = 3x^2 + 12x + 16
The minimum of G(x) is -2 and of F(x) is 4 So, G(x) has the smallest minimum y-value.
The function G(x) is a sine function. The sine function, sin(x), has a range of -1 to 1. The minimum value of sin(x) is -1. Since G(x) = 2 sin(x - π), we multiply the minimum value of sin(x) by 2.
The minimum value of sin(x - π) is:
sin(x - π) = -1
Thus, the minimum value of G(x) is:
2 * (-1) = -2
To find the minimum value of a quadratic function, we use the vertex formula, x = -b / 2a. For F(x), a = 3, b = 12, and c = 16.
The x-coordinate of the vertex is:
x = -12 / (2 * 3) = -12 / 6 = -2
Substitute x = -2 into the function to find the minimum y-value:
F(-2) = 3(-2)² + 12(-2) + 16
F(-2) = 3(4) - 24 + 16 = 12 - 24 + 16 = 4

The difference between the roots of the quadratic equation x2+x+c=0 is 6. Find c.
To solve this question:
First, we compare with the standard quadratic equation to find a, b and c.Then, we apply Bhaskara to find the roots, as function of c.Then, since the difference is 6, we use this to find c.Doing this, we get that: [tex]c = -\frac{35}{4}[/tex]
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
[tex]ax^{2} + bx + c, a\neq0[/tex].
This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:
[tex]x_{1} = \frac{-b + \sqrt{\Delta}}{2*a}[/tex]
[tex]x_{2} = \frac{-b - \sqrt{\Delta}}{2*a}[/tex]
[tex]\Delta = b^{2} - 4ac[/tex]
x²+x+c=0
Comparing with the standard second order equation, which is:
[tex]ax^2 + bx + c = 0[/tex]
We get that:
[tex]a = 1, b = 1[/tex]
Finding the roots:
[tex]\Delta = b^{2} - 4ac = 1^2 - 4(1)(c) = 1 - 4c[/tex]
[tex]x_{1} = \frac{-1 + \sqrt{1 - 4c}}{2}[/tex]
[tex]x_{2} = \frac{-1 - \sqrt{1 - 4c}}{2}[/tex]
Difference of 6
Thus:
[tex]x_1 - x_2 = 6[/tex]
[tex]\frac{-1 + \sqrt{1 - 4c}}{2} - \frac{-1 - \sqrt{1 - 4c}}{2} = 6[/tex]
[tex]-\frac{1}{2} + \frac{\sqrt{1 - 4c}}{2} + \frac{1}{2} + \frac{\sqrt{1 - 4c}}{2} = 6[/tex]
[tex]\frac{2\sqrt{1 - 4c}}{2} = 6[/tex]
[tex]\sqrt{1 - 4c} = 6[/tex]
[tex](\sqrt{1 - 4c})^2 = 6^2[/tex]
[tex]1 - 4c = 36[/tex]
[tex]-4c = 35[/tex]
[tex]4c = -35[/tex]
[tex]c = -\frac{35}{4}[/tex]
Thus, [tex]c = -\frac{35}{4}[/tex] is the value.

The fuel for a chain saw is a mix of oil and gasoline. The ratio of ounces of oil to gallons of gasoline is 5:18. There are 36 gallons of gasoline. How many ounces of oil are there?
16 ounces
10 ounces
129.6 ounces
2.5 ounces
The amount of oil, in ounces, in the fuel mix can be found using a proportion with the given ratio and the amount of gasoline.
Explanation:To find the number of ounces of oil, we need to use the given ratio and the amount of gasoline. The ratio of oil to gasoline is 5:18, meaning that for every 5 ounces of oil, there are 18 gallons of gasoline. Since we know that there are 36 gallons of gasoline, we can set up a proportion to find the number of ounces of oil:
5 ounces / 18 gallons = x ounces / 36 gallons
Cross multiplying, we get:
18x = 5 * 36
Simplifying further:
18x = 180
Dividing both sides by 18, we get:
x = 10 ounces

if tan(145) = -1/1.43 , what is tan(-125) A. -1.43, B. 1.43, C. 1/1.43, D. -1/1.43
Answer:
B. 1.43
Step-by-step explanation:
Because tan (180-θ)=-tan θ
[tex]tan (145) = tan (180 -35)= -tan 35 = -\frac{1}{1.43}\\tan 35 =\frac{1}{1.43}[/tex]
Because tan (90+θ) = -cot θ
tan (-125) can be written as:
[tex] tan(-125)=-tan (125) = - tan (90+35) = cot 35[/tex]
tan θ x cot θ =1
⇒tan 35 x cot 35 = 1
⇒[tex]\frac{1}{1.43} \times cot 35 =1 \\ cot 35 = 1.43[/tex]
⇒[tex] tan(-125)= cot 35 = 1.43[/tex]

The length of a rectangle is 2 cm longer than its width. if the perimeter of the rectangle is 36 cm , find its area.
The area of the rectangle is 80 square cm.
Explanation:To find the area of a rectangle, we need to know the length and width. Let's denote the width of the rectangle as 'w'. As given, the length of the rectangle is 2 cm longer than its width, so the length can be represented as 'w + 2'.
The perimeter of a rectangle is the sum of all four sides. In this case, it is given as 36 cm. Using the formula for the perimeter of a rectangle, we can set up the equation:
2(w + w + 2) = 36
Simplifying the equation:
4w + 4 = 36
4w = 32
w = 8
Substituting the value of 'w' back into the expression for length:
Length = 8 + 2 = 10
The area of a rectangle is given by the formula: area = length × width. So, the area of this rectangle is:
Area = 10 × 8 = 80 square cm

ray bought 5 lemons and 3 limes for $7.20. Lia bought 4 lemons and 6 limes for the same price. How much would it cost to buy 1 lemon and 1 lime?
Answer: The cost of 1 lemon is $1.2 and the cost of 1 lime is $0.4.
Step-by-step explanation:
Let x be the cost of 1 lemon and y be the cost of 1 lime.
Then for Ray, the equation representing total price will be :-
[tex]5x+3y=7.20[/tex]................................(1)
For Lia, the equation representing total price will be :-
[tex]4x+6y=7.20[/tex]..................................(2)
Dividing 2 on the both sides of equation (2), we get
[tex]2x+3y=3.60[/tex]...............................(3)
Subtracting (3) from (1), we get
[tex]3x=3.6\\\\\Rightarrow x=1.2[/tex]
Substitute value of x in (3), we get
[tex]2(1.2)+3y=3.6\\\\\Rightarrow2.4+3y=3.6\\\\\Rightarrow3y=1.2\\\\\Rightarrow y=0.4[/tex]
Thus, the cost of 1 lemon is $1.2 and the cost of 1 lime is $0.4.
