if p + 2q = 40 find Q when p = 16
Plug in the value of p:-
16+2q=40
Subtract 16 from both sides:-
2q=40-16
2q=24
Divide both sides by 2:-
q=12 ✓

write the equation of line through (3,6) and (-4,-1)
Answer:
y=x+3
Step-by-step explanation:
The slope of a line passing through the two points P = (x1, y1)and Q = (x2, y2) is given by
m= (y2-y1)/(x2-x1)
We have that x1= 3, y1= 6, x2= - 4, y2= - 1
so m = 1
Now, the y-intercept is b=y1-mx1 (or b=y2-mx2, the result is the same).
b=6-(1)(3)
b=3
Finally, the equation of the line can be written in the form
y = mx+b
y=x+3

At a concession stand, seven hot dog(s) and four hamburger(s) cost $21:25, four hot dog(s) and seven hamburger(s) cost $22.75 Find the cost of one hot dog and the cost of one hamburger
Step-by-step explanation:
If 4 hamburger = $21.25
1 hamburger = x
Cross multiply
4 x x = $21.25 x 1
4x = $21.25
Devide both side with the coefficient of x
4x/4 = $21.25/4
X = $5.3125
Therefore 1 hamburger cost $5.31
If 4 hotdogs = $22.75
1 hotdog = y
Cross multiply
4 x y = $22.75 x 1
4y = $22.75
Devide both sides with the coefficient of y
4y/4 = $22.75/4
Y = $5.6875
Therefore one hotdog cost $5.69
Answer:
See below ↓↓↓
Step-by-step explanation:
Given :
7 hot dogs + 4 hamburgers = $21.504 hot dogs + 7 hamburgers = $22.75Let's set some variables.
hot dogs = xhamburgers = ySo, our equations are :
7x + 4y = 21.504x + 7y = 22.75Mulitply equation #1 by 7 and equation #2 by 4.
49x + 28y = 150.50 (Equation 3)16x + 28y = 91.00 (Equation 4)Subtract equation 4 from equation 3.
49x - 16x + 28y - 28y = 150.5 - 9125x = 59.5x = $2.38 [cost of one hot dog]Substitute value of x in equation 4.
16(2.38) + 28y = 9138.08 + 28y = 9128y = 52.92y = $1.89 [cost of one hamburger]Last year, Handy Hardware

Using translation concepts, it is found that his mistake was that he made the shifts on the wrong coordinates, and the new location is at (1,5).
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
Initially, researching the problem on the internet, it is found that the market is at position (3,8).
Then, it was shifted 2 units left and 3 units down, hence the new position is given by:
(3 - 2, 8 - 3) = (1,5).
His mistake was that he made the shifts on the wrong coordinates, and the new location is at (1,5).

Mai and her sister are planting a garden.They made 2 plant beds.one was 4 feet by 3 feet and the other 5 feet by 5 feet.they want to outline the beds with bricks that are 1foot long.How many bricks will they need to outline both beds?
Answer:
27 bricks
Step-by-step explanation:
find the perimeter of the first one, 4 x 3 = 12. Then the perimeter of the second one, 5 x 5 = 25. Therefore 12 + 15 = 27. Meaning you need 27 bricks

Answer:y=x^2 translated 3 to the right gives
y=(x-3)^2, the vertex shifts from (0,0) to (3,0)
translate it 4 up by adding 4
y=(x-3)^2 + 4, this shifts the vertex up to (3,4)
f(x) = (x-3)^2 + 4 or call it
g(x) = (x-3)^2 + 4 if you want to distinguish it from the original f(x) function
Step-by-step explanation:In this question we have been given a function f(x) = |x|
When we perform a translation of 4 units right then the translated form of the function becomes f(x) = |x - 4|
And when we we translate the function up by 2 units then the transformed form is f(x) = |x - 4| + 2
Therefore the given graph in option B is the correct option.

Solve for x: 3 (square root2-2x)+1=13
Answer:
x=7
Step-by-step explanation:
3√(2-2x) + 1 = 13
subtract 1 from both sides
3√(2-2x) = 12
Divide 3 from both sides
√2-2x= 4
square both sides
2-2x = 16
subtract 2 from both sides
2x= 14

Find the slope of the line passing through the points (7, -3) and (3, -7)
Answer:
The slope of the line is -1
Step-by-step explanation:
You need to use the slope formula
Slope Formula: y2 - y1 / x2 - x1
**The numbers represent subscripts but the subscripts aren't on computers**
Your Coordinate Points:
(7, -3) and (3, -7)
Do -7 - (-3) / 3-7
First, do -7 - (-3)
The negatives cancel to an addition problem.
-7 + 3
Now do -7 + 3. This is a subtraction problem that should be negative.
-7 + 3 = -4
Next, do 3 - 7
That should be 4
-4/4 is what we have right now.
Do -4 divided by 4 which has to contain a negative.
That is simply -1.
The slope of the line is -1

Find the sum of the first 21 terms of the arithmetic progression.
−7, −11, −15, . . .
We are given with an AP (Arithmetic Progression) with first term being -7, and the common difference being the difference between any succeding term from any term and the term itself, so common difference = -11 - (-7) = -11 + 7 = -4, so now before finding the sum of 21 terms, let's recall that ;
[tex]{\boxed{\bf{S_{n}=\dfrac{n}{2}\{2a+(n-1)d\}}}}[/tex]Where, d is the common difference, a is the first term, and n is the number of terms and [tex]{\bf S_n}[/tex], being the sum of n terms, so putting all the values in the formula, we will have ;
[tex]{:\implies \quad \sf S_{21}=\dfrac{21}{2}\{2\times -7+(21-1)-4\}}[/tex]
[tex]{:\implies \quad \sf S_{21}=\dfrac{21}{2}(-8+20\times -4)}[/tex]
[tex]{:\implies \quad \sf S_{21}=\dfrac{21(-8-80)}{2}}[/tex]
