Answer:
x= 10, y= 6
Step-by-step explanation:
2x -3y= 2 -----(1)
-2x -y= -26 -----(2)
(1) +(2):
2x -3y -2x -y= 2 -26
-4y= -24
y= -24 ÷(-4)
y= 6
Substitute y= 6 into (1):
2x -3(6)= 2
2x -18= 2
2x= 18 +2
2x= 20
Divide both sides by 2:
x= 20 ÷2
x= 10

edgar ran 1/15 of a mile on monday, 1/5 of a mile on tuesday, and 1/3 of a mile on thursday. what is thee total amount of miles edgar ran in 3 days??
[tex] \frac{1}{15} + \frac{1}{5} + \frac{1}{3} [/tex]
to find:the simplest form.
solution:[tex] \frac{1}{15} + \frac{1 \times 3}{5 \times 3} + \frac{1 \times 5}{3 \times 5} [/tex]
[tex] = \frac{1}{15} + \frac{5}{15} + \frac{3}{15} [/tex]
[tex] = \frac{1 + 3 + 5}{15} [/tex]
[tex] = \frac{9}{15} [/tex]
[tex] = \frac{3}{5} [/tex]

Answer:
(5x^2-6)*(2x-7)
Step-by-step explanation:
1.(((10 • (x3)) - (5•7x2)) - 12x) + 42
2.(((2•5x3) - (5•7x2)) - 12x) + 42
3. 10x3-35x2-12x+42 is not a perfect cube
4.Factoring: 10x3-35x2-12x+42
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: -12x+42
Group 2: 10x3-35x2
Pull out from each group separately :
Group 1: (2x-7) • (-6)
Group 2: (2x-7) • (5x2)
-------------------
Add up the two groups :
(2x-7) • (5x2-6)
5. Factoring: 5x2-6
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
= (5x2 - 6) • (2x - 7)

Find the domain of the graphed function.
Answer:
D. 2 ≤ x ≤ 5
The domain is the x values of the graph.
Here, we have points with x values at 2 and 5. Since the function stays within these two points, our domain is;
D. 2 ≤ x ≤ 5
We always use the y values as the range of a function on a graph while x values gives us the Domain . So , by looking at the above graph we can say that , [tex]{\pmb{\bf x \in [2,5]}}[/tex] or can further written as [tex]{\bf 2\leq x\leq 5}[/tex] .
Henceforth , Option D) [tex]{\bf 2\leq x\leq 5}[/tex] is correct

Let other 2 angles be d
44 + 2d = 180°
(sum of triangle)
2d = 180 -44
2d = 136
d = 136/2
d = 68
x = 68 + 44 (exterior angle is equal to sum of interior opposite angles)
x = 112°

- 12 ÷ (-4)
How do I solve this?
Step-by-step explanation:
We're going to be diving -12 by -4.
What do we need to know?
Integer Rule - when 2 negative numbers multiply or divide, the product/quotient is positive.
Solve using the integer rule:
[tex]-12 \div -4 =3[/tex] is the same as [tex]12 \div 4 = 3[/tex]
3 is your quotient.

A triangle has side lengths of (9f+g) centimeters, (5f+9h)centimeters, and (2h+7g) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?
Answer:
Step-by-step explanation:
Perimeter is sum of all the sides.
Perimeter = 9f + g + 5f + 9h + 2h + 7g
= 9f + 5f + g +7g + 9h + 2h {Combine like terms}
= 14f + 8g + 11h
If Janelle originally started 575
miles from Mammoth Lakes and continues traveling at the same rate (from part (a)), how many more hours will it take her to arrive at her destination?
Given that Janelle travels at 65 mph. the number of more hours it will
take her to reach her destination is approximately 5 hours.
How can the time to reach her destination be calculated?Possible part of the question that appear missing are;
The distance Janelle drove in 4 hours = 260 miles
The distance from which she started = 575 miles
Required:
The number of extra hours it will take her to reach her destination
Solution:
The remaining distance = 575 miles - 260 miles = 315 miles
[tex]Speed = \mathbf{ \dfrac{Distance}{Time}}[/tex]
[tex]Janelle's \ average \ speed = \dfrac{260 \, miles }{4 \, hours} = \mathbf{ 65 \, mph}[/tex]
[tex]Time = \dfrac{Distance}{Speed}[/tex]
Which gives;
[tex]Time \ to \ reach \ her \ destination = \dfrac{315 \, miles}{65 \, mph} = 4\frac{11}{13} \, hours \approx \mathbf{ 5 \, hours}[/tex]
The time it takes Janelle to reach her destination ≈ 5 hours

F(5, 7)Step-by-step explanation:
Part AFind the equation of AB using the coordinates of the endpoints:
A(- 1, - 1), B(2, 3)Find the slope:
m = (3 - (-1)) / (2 - (-1)) = 4/3Use one of the points and point-slope equation to get the line:
y - 3 = 4/3(x - 2)y - 3 = 4/3x - 8/3y = 4/3x + 3 - 8/3y = 4/3x + 1/3Now find the y - coordinate of F when x is 5:

$27 for four large pizzas or $32 for five large pizzas
Answer: $27 for four large pizzas is cheaper than 32$ for five large pizzas
Step-by-step explanation:
Answer:
$32 for 5 pizzas
Step-by-step explanation:
Assuming you're trying to determine which option is the better deal, the first step would be to determine the price per pizza.
Option 1: $27 for 4 pizzas
$27 / 4 pizzas = $6.75 per pizza
Option 2: $32 for 5 pizzas
$32 / 5 pizzas = $6.40 per pizza
Option 2 is the better deal because each pizza costs less.

Square ABCD is similar to square EFGH. The ratio of AB:EF is 1:4. The area of square EFGH is 14,000ft^2. What is AB?
Answer: 5sqrt(35)
Step-by-step explanation:
If the ratio of the side lengths is 1:4, since the ratio of the areas is the square of the ratio of the side lengths, the ratio of the areas is 1:16.
This means the area of square ABCD is 14000/16 = 875.
Therefore, AB=sqrt(875)=5sqrt(35).
