Jenifer bought 6 packages of hotdogs and 8 packages of rolls for $41.50. A package of rolls cost $0.85 less than a package of hotdogs. How much did each package of hotdogs cost?
Answer:
hotdogs 3.45
rolls 2.60
Step-by-step explanation:
6h + 8r = 41.5
r=h-.85
6h + 8(h-.85)=41.5
6h + 8h - 6.8 = 41.5
14h = 41.5 + 6.8
14h = 48.3
h=48.3/14
h=3.45
r=3.45-.85=2.6

answer
Answer:
h=5
Step-by-step explanation:
Let's solve your equation step-by-step.
5h−13=12
Step 1: Add 13 to both sides.
5h−13+13=12+13
5h=25
Step 2: Divide both sides by 5.
5h /5 = 25 /5
h=5
I this helps may I get brianliest?
Answer: h = 5
Step-by-step explanation: 5h + 13 = 12 -13 + 5h = 12 ( h ) 0 + 5h = 12+13 5h = 25 ~ 5

A quadratic function has its vertex at the point (6,10). The function passes through the point (7, – 4).
Find the quadratic and linear coefficients and the constant term of the function.
The quadratic coefficient:
The linear coefficient is:
The constant term is:
I’m confused
Answer:
Quadratic coefficient = -14, linear coefficient = 168, constant term = -494
Step-by-step explanation:
Its easiest to first start out with a vertex form equation because it can then be converted to a standard quadratic.
given a vertex at (6,10) , and point of intersection at (7,-4), the equation can be set up like this:
y = a(x-6)^2+10, because we know h and k from the vertex.
We also know y and x from the given point of intersection so a can be solved.
-4 = a(7-6)^2+10
-4 = a + 10
-4-10 = a
a = -14 which is also known as the quadratic coefficient because it is part of a second degree quantity and a Trionomial as a whole(quadratic).
since all the variables are known, you can
expand the equation and set it to standard form
y = -14(x-6)^2+10
y = -14(x^2-12x+36)+10
y = -14x^2+168x-504+10
y = -14x^2+168x-494
For reference, the standard form equation is ax^2+bx+c where a is the quadratic coefficient, b is the linear coefficient, and c is the constant coefficient.
In this instance, -14x^2+168x-494 = ax^2+bx+c

6 honeycrisp apples cost $1.99. How much do 11 apples cost?
.Answer:
3.65
Step-by-step explanation:
if 6 apples = $1.99, if you divide $1.99 by 6, you get the cost for one, then if you multiply that by 11, you get the amount for 11 apples. The real total is $3.64833333333 but if you round it, it goes to $3.65

Find the value of x in each case:
L, M ∈ KN
Answer:
x = 27
Step-by-step explanation:
From the picture attached,
m∠PLM + m∠PLK = 180° [Linear pair of angles are supplementary]
m∠PLM + 3x = 180°
m∠PLM = 180° - 3x
Similarly, m∠PML + m∠PMN = 180° [Linear pair of angles]
m∠PML + (2x + 72)° = 180°
m∠PML = 180° - (2x + 72)°
From triangle PLM.
m∠PLM + m∠PML + m∠LPM = 180° [Sum of interior angles of a triangle = 180°]
(180 - 3x) + 180 - (2x + 72) + x = 180
180 - 3x - 2x - 72 + x = 0
-4x + 108 = 0
x = [tex]\frac{108}{4}[/tex]
x = 27

The domain is the set of values for which the given function is defined. The domain of the given function is 0≤x≤7.5. The correct option is B.
What is the domain and range of a function?The domain is the set of values for which the given function is defined.
The range is the set of all values which the given function can output.
Given that function b model the bagel inventory, b(x), after x hours of opening, and it is given as,
b(x) = 75 - 10x
Now, the domain of the function is the values that x can take in the function. Since x represents the number of hours after opening, therefore, it can not be negative and must start with zero.
Further, since the inventory or the total number of bagels that the shop has is 75, therefore, they can not sell more than that, and at some point, the inventory will become zero. Therefore, we can write,
75 - 10x = 0
-10x = -75
10x = 75
x = 75 /10
x = 7.5 hours
Hence, the domain of the given function is 0≤x≤7.5.

There are 60 * 60 * 24 = 86400 seconds in a day
if the light flashes 5 times every 10 seconds, that means it flashes once every 2 seconds.
It follows the flashes in a day are 86400 / 2 = 43200
como resolver a equação -7. (x-3)=x +5
Answer:
[tex]x=2[/tex]
Step-by-step explanation:
[tex]-7(x-3)=x+5[/tex]
Distribute the [tex]-7[/tex] into [tex](x-3)[/tex]:
[tex]-7x+21=x+5[/tex]
Subtract [tex]x[/tex] from both sides of the equation:
[tex]-8x+21=5[/tex]
Subtract [tex]21[/tex] from both sides of the equation:
[tex]-8x=-16[/tex]
Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]-8[/tex]:
[tex]x=2[/tex]

Theequationforlineucanbewrittenasy = 6x + 6 . Line v , whichisperpendiculartoline u , includes the point (10, –5) . What is the equation of line v ? Write the equation in slope-intercept form. Write the numbers in the equation as proper fractions, improper fractions, or integers.
Answer:
[tex]y=\frac{-1}{6}x-\frac{10}{3}[/tex]
Step-by-step explanation:
Slope intercept form of the equation of a line is [tex]y=mx+b[/tex] where m denotes the slope of line and [tex]b[/tex] denotes the y-intercept.
Equation of a line u is [tex]y=6x+6[/tex]
Here, slope of line u = m = 6
As the line v is perpendicular to line u, product of slopes of both the lines is equal to [tex]-1[/tex].
Slope of line v [tex]=\frac{-1}{6}[/tex]
So, slope intercept form of the line v is [tex]y=\frac{-1}{6}x+b[/tex]
As point [tex](10,-5)[/tex] lies on the line v, put [tex](x,y)=(10,-5)[/tex] in equation [tex]y=\frac{-1}{6}x+b[/tex]
[tex]-5=\frac{-1}{6}(10)+b\\-5=\frac{-5}{3}+b\\ -5+\frac{5}{3}=b\\\frac{-15+5}{3}=b\\\\\frac{-10}{3}=b[/tex]
Equation of line v is [tex]y=\frac{-1}{6}x-\frac{10}{3}[/tex]
