Answer:
(p, q ) = (1, - 3 )
Step-by-step explanation:
2p + 3q = - 7 → (1)
3p + 5q = - 12 → (2)
Multiplying (1) by 3 and (2) by - 2 and adding the result will eliminate p
6p + 9q = - 21 → (3)
- 6p - 10q = 24 → (4)
Add (3) and (4) term by term to eliminate p
0 - q = 3
-q = 3 ( multiply both sides by - 1 )
q = - 3
Substitute q = - 3 into either of the 2 equations and solve for p
Substituting into (1)
2p + 3(- 3) = - 7
2p - 9 = - 7 ( add 9 to both sides )
2p = 2 ( divide both sides by 2 )
p = 1

Find the domain of the function shown in the graph below?
Answer:
All real numbers with vertical asymptotes at -2 and 6
Step-by-step explanation:
The domain of the function is all the possible x values of the function, so the solution is all real numbers with vertical asymptotes at -2 and 6 because the values never cross here.

A recipe for trail mix says: “Mix 7 ounces of almonds with 5 ounces of raisins.” How many batches would there be if you have 250 ounces of raisins?
Answer:
20.8333333333
Step-by-step explanation:
7 + 5 = 12. 250 divided by 12 equals 20.8333333333 or 20.833... You will have more than 20 and a half batches but you can just say about 21, however needed.
On a trip, you see a large, sphere-shaped house. The volume of the house was 3,367,575 cubic feet. What is the radius? Use 3.14 to approximate pi. Round your answer to the nearest whole number.
Answer:
r≈93
Step-by-step explanation:
V=4/3πr³
3,367,575=4/3(3.14)r³
3,367,575=314/75r³
multiply both sides by 75/314
804357 27/314=r³
∛804357 27/314=∛r³
r≈93
Donna cut away 7.75 meters of rope. Before that, she had 12 meters of rope. How much rope does Donna have left?
Answer: 4.25 meters of rope
Step-by-step explanation:
Because Donna is losing 7.75 meters of rope from her original 12 meters, this problem can simply be represented as 12 - 7.75, which equals 4.25.

does anyone know how to do this..?
Answer:
a. x=29, b. x=62
Step-by-step explanation:
a. since this is an isosceles triangle, two angles are equal. we also know that the exterior angle of one side equals the other 2 interior angles. so we have 2x=58, simplify to get x=29
b. same as a, we have x-17 + 38 = 2x-41. simplify to get x+21 = 2x-41. subtract x and add 41 to both sides to get x=62

a number y divided by 4 is greater than 22
Answer:
y ÷ 4 ≥ 22
Step-by-step explanation:
I can't find the greater than symbol, but just write the "≥" without the line underneath
Answer:
44
Step-by-step explanation:
Let the number be X
B/P,
X/4=22 Or, X=22*4
X=88
X/2=88/2=44
So the quotient of the number when divided by 2 is 44.

Using the formula find the slope of a line with these two points (2,10) and (5,15).
Answer:
Step-by-step explanation:
[tex]\left(x_{1},y_{1} \right) = (2,10)\\\\(x_{2},y_{2}) = (5 ,15}\\\\\\Slope =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\\\=\dfrac{}15-10{5-2}=\dfrac{5}{3}\\\\\\= \dfrac{5}{3}[/tex]
Answer:
slope = [tex]\frac{5}{3}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (2, 10 ) and (x₂, y₂ ) = (5, 15 )
m = [tex]\frac{15-10}{5-2}[/tex] = [tex]\frac{5}{3}[/tex]

Lena is asked to write an explicit formula for the graphed geometric sequence. On a coordinate plane, 3 points are plotted. The points are (1, 1), (2, 2. 5), (3, 6. 25). What value, written as a decimal, should Lena use as the common ratio? 1. 0 1. 5 2. 5 2. 0.
Answer:
r = 2.5
Step-by-step explanation:
Consider the y- coordinates of the plotted points
1 , 2.5 , 6.25
The common ratio r is calculated as
r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{a_{3} }{a_{2} }[/tex] = [tex]\frac{2.5}{1}[/tex] = [tex]\frac{6.25}{2.5}[/tex] = 2.5
I’m confused…Find u and v
i started some of it but i’m really confused with the rest. does anyone know how to do this?
Answer:
see below
Step-by-step explanation:
You're doing well! The parts of the table you've done are correct.
For x = 1, you switch to the second part of the function rule (because that part says to use it if [tex]x \ge 1[/tex].
x =1 : 6 - 2(1) = 4 (1, 4)
x = 2: 6 - 2(2) = 2 (2, 2)
x = 3: 6 - 2(3) = 0 (3, 0)
x = 4: 6 - 2(4) = -2 (4, -2)
Each of the parts of the function rule graph as pieces of straight lines. The first part will be a straight line through points (-4, 1), (-3, 0), (-2, 1), (0, 3) but that part of the graph stops at point (1, 4). Point (1, 4) is on BOTH parts of the graph, so the two lines connect at that point.

what is the value of x+3x+11X
Step-1 : Multiply the coefficient of the first term by the constant 3 • -20 = -60
Step-2 : Find two factors of -60 whose sum equals the coefficient of the middle term, which is -11 .
-60 + 1 = -59
-30 + 2 = -28
-20 + 3 = -17
-15 + 4 = -11
That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -15 and 4
3x2 - 15x + 4x - 20
Step-4 : Add up the first 2 terms, pulling out like factors :
3x • (x-5)
Add up the last 2 terms, pulling out common factors :
4 • (x-5)
Step-5 : Add up the four terms of step 4 :
(3x+4) • (x-5)
Which is the desired factorization

pls answer 4th and 5th question . i do not understand
Step-by-step explanation:
4) total length of the journey is
1st hr = 74km 224m = 74224m
2nd hr = 74km 224m = 74224m
3rd hr = 58km 56m = 58056m
4th hr = 62km 8m = 62008 m
total distance (adding all) = 268512m = 268km 512m .
5) total weight = 22kg 200g = 22200g
mangoes weight = 14kg 750g = 14750g
apples weight = 5kg 80g = 5080g
total weight - fruits weight
(22200-14750-5080)g
= 2370g
= 2kg 370g.
hope this helps you.

Answer:
∠ 1 = ∠ 3 = 52°
Step-by-step explanation:
∠ 3 and ∠ 6 are same- side interior angles and sum to 180° , so
∠ 3 + ∠ 6 = 180° , that is
∠ 3 + 128° = 180° ( subtract 128° from both sides )
∠ 3 = 52°
∠ 1 and ∠ 3 are vertically opposite angles and are congruent , then
∠ 1 = 52°

The width of a rectangle is 5 cm more than twice the length the perimeter is 56 cm find the dimensions of the rectangle
Answer: W = 20 1/3, L = 7 2/3 cm
Step-by-step explanation:
Width, W, is 5 cm more than twice the length of the perimeter.
Perimeter = 2W + 2L
W = 2L+5
Perimeter is 56cm:
56 cm = 2W + 2L
Substitute W = 2L + 5 for W:
56 cm = 2W + 2L
56 cm = 2(2L+5) + 2L
56 cm = 4L + 10 + 2L
6L = 46 cm
L = 7 2/3 cm
Since W = 2L + 5
W = 2(7 2/3) + 5
W = 2 (23/3) + 5
W = 46/3 + 5
W = 15 1/3 + 5
W = 20 1/3
2W + 2L = P?
2(20 1/3) + 2(7 2/3) =56 ?
40 2/3 + 15 1/3 = 56?
56 = 56 YES
