Answer:
(x, y) = (1, 4)
Step-by-step explanation:
Given: x+y=5 and 2x-y=-2
Solve for y and x
x+y=5; solve for y
y = 5 - x; substitute into other equation
2x-y= -2
2x - (5 - x) = -2
2x - 5 + x = -2; combine x's
3x - 5 = -2; add 5 to both sides
3x =3; divide by 3
x = 1; use this to solve for y
x+y=5
1 + y = 5; subtract 1 from both sides
y = 4
(x, y) = (1, 4)
In this hanger, the weight of the triangle is x and the weight of the square is y.
Write an equation using x and y to represent the hanger.
9514 1404 393
Answer:
x +3y = 4x +y
Step-by-step explanation:
Apparently, the "hanger" is in balance between its left side, which weighs x+3y, and it right side, which weighs 4x+y. We can represent this balance by ...
x +3y = 4x +y

You are recreating a scale drawing at a different scale. The original scale is 1 cm : 8 m. The new scale is 1 cm : 2 m. In the original drawing, the length of a segment is 9 centimeters. How long should the segment representing the same distance be in the new drawing?
The segment should be ?centimeters long.
Answer:
The segment should be 36 centimeters long
Step-by-step explanation:
Let us use the ratio method to solve the question
∵ The original scale is 1 cm : 8 m
∵ In the original drawing, the length of a segment is 9 centimeters
→ By using the ratio method
→ cm : m
→ 1 : 8
→ 9 : x
→ By using the cross multiplication
∵ 1 × x = 9 × 8
∴ x = 72 m
∴ The actual length of the segment is 72 m
∵ The new scale is 1 cm : 2 m
∵ The actual length of the segment is 72 m
→ By using the ratio method
→ cm : m
→ 1 : 2
→ y : 72
→ By using the cross multiplication
∵ y × 2 = 1 × 72
∴ 2y = 72
→ Divide both sides by 2 to find y
∴ y = 36
∴ The drawing length of the segment is 36 cm in the new scale
∴ The segment should be 36 centimeters long

Amira is told there is a trick to finding the slope within an equation in standard form, Ax + By= C. She is told she can rewrite this equation in slope-intercept form, y = mx + b, to find the pattern. She correctly rewrites the equation 7x + 9y = 14 in slope-intercept form as y = - 7/9 x + 14/9. Which answer explains the pattern for how to find the slope using an equation in standard form?
Answer:
The slope of given equation in standard form
[tex]m = \frac{-7}{9}[/tex]
Step-by-step explanation:
Explanation:-
Given equation of the line 7x + 9y = 14
The given equation in slope-intercept form, y = mx + b
Slope - intercept form [tex]y = \frac{-7}{9} x + \frac{14}{9}[/tex]
Comparing m = - 7/9
Here m = -7/9
C = 14/9
The slope of given equation in standard form
[tex]m = \frac{-7}{9}[/tex]
In AEB,CD is parallel to AB. Complete each proportion please help!!!!!!!!!!!!
Answer:
see explanation
Step-by-step explanation:
Given a line CD parallel to a side of the triangle and intersecting the other 2 sides, then it divides those sides proportionally, thus
(a)
[tex]\frac{EC}{CA}[/tex] = [tex]\frac{ED}{DB}[/tex]
(b)
[tex]\frac{EC}{EA}[/tex] = [tex]\frac{ED}{EB}[/tex]
(c)
[tex]\frac{EB}{ED}[/tex] = [tex]\frac{EA}{EC}[/tex]
(d)
[tex]\frac{DB}{EB}[/tex] = [tex]\frac{CA}{EA\\}[/tex]

Can someone help plz? Jack and Jessica earned the same amount last week. Jack earned $18 per hour and had $41 taken from his check for taxes LaTeX: (18x-41)( 18 x − 41 ). Jessica earned $15 per hour and had $17 deducted from her pay. How many hours did each work in order to get paid the same amount?
Write the equation
Solve for the number of hours
Answer:
the answer is 8
Step-by-step explanation: so first what you want to do is you want to set up the equation 18x-41. then you want to do 15x because of the 15 per hour. then you minus 17. so your equation is 18x-41=15x-17 then the answer to that is 8 hours

URGENT!! WILL MARK BRAILIEST! GOD BLESS. PLEASE SHOW ALL WORK. The age of Vicky and Krishna total 27 years. In 4 years, Krishna’s age plus twice Vickey’s age will be 43. What are Vickey and Krishna’s ages?
9514 1404 393
Answer:
Vickey is 4Krishna is 23Step-by-step explanation:
Let v represent Vickey's age now. Then Krishna's age now is 27-v. In 4 years, the sum of their ages is ...
(27 -v +4) +2(v +4) = 43
27 -v +4 +2v +8 = 43 . . . . eliminate parentheses
v +39 = 43 . . . . . . . . . . . . . collect terms
v +39 -39 = 43 -39 . . . . . . subtract 39 from both sides
v = 4 . . . . . . . . . . . . . . . . . simplify; this is Vickey's age
27 -v = 23 . . . . . Krishna's age
Vickey's age is 4; Krishna's age is 23.

Answer:
[tex]u_{n} = 2n^{2} -4n-3[/tex]
Step-by-step explanation:
a +b + c = - 5 First term in sequence
3a + b = 2 Difference between first two terms
2a = 4 Difference between the difference of the first two terms and the second third terms (the difference between -5 and -3 is 2 the difference between -3 and 3 is 6; the difference between 6 and two is 4)
2a = 4 so a = 2; 3(2) + b = 2 → 6 + b = 2 so b = -4; 2 - 4 + c = -5 → -2 + c = -5 so c = -3

Step-by-step explanation:
Write an equation in slope-intercept form of the line that passes through the given points.
Answer:
y=3/2x+2
Step-by-step explanation:
The slope is 3/2
To find it find to perfect points or "pretty points" and rise then run, so the point (0,2) is a pretty point and (2/5) is a pretty point to get to this point you rise 3 and run 2, so 3/2.
The y-intercept is 2
To find the y-intercept all you need to do is find the point that passes through the y-axis, so (0,2) the y-intercept would be 2.
