Seashells glued on 1 photo frame = k
So, seashells glued on 5 photo frame
= Seashells glued on 1 photo frame × 5
= k × 5
= 5k
So, Erynn used 5k seashells.
Answer:
y = 4x - 2
When y = 26, x = 7.
Step-by-step explanation:
Use the two points on the line to calculate the slope of the line, then use this slope and the y-intercept to write an equation for the line.
Slope formula:
We have these two points on the graph: (1, 2), (-1, -6).
Substitute these points into the slope formula and find the slope of the line.
The slope of the line is 4. Now, use the point-slope formula to write an equation for the line.
Point-slope formula:
- y - y1 = m(x - x1)
- y - 2 = 4(x - 1)
- y -2 = 4x - 4
- y = 4x - 2
To find the value of x when y = 26, substitute y = 26 into the equation and solve for x.
- 26 = 4x - 2
- 28 = 4x
- x = 7
A reduction of 15% per year means 100-15=85% reducing factor.
1st year: 0.85×18000=$15300.
2nd year: 0.85×15300=$13005.
3rd year: 0.85×13005=$11054.25.
So after 3 years the value of the car is $11054.25 or $11054 to the nearest dollar.
The answer is 6.33 units.
Answer:
x = 5/2
y = -2
Step-by-step explanation:
(1+i)² (x+yi) = 4+5i
(1+2i+i²)(x+yi) = 4+5i
(1+2i-1)(x+yi) = 4+5i
2i(x+yi) = 4+5i
2i²y + 2xi = 4+5i
-2y + 2xi = 4 + 5i
By comparing both sides,
-2y = 4
y = -2,
2x = 5
x = 5/2
