The slope-intercept form of the equation for a line with a slope of -4 and a y-intercept of -2 is ...
y = -4x -2
Answer:
Answer:C = 8
Answer:C = 8Step-by-step explanation:
-2(4c+16)^1/4+2=-2
Move the constant to the right and change the sign
-2(4c+16)^1/4= -2-2
transform expression
![- 2 \sqrt[4]{4c - 16} = - 4](https://tex.z-dn.net/?f=%20-%202%20%20%5Csqrt%5B4%5D%7B4c%20-%2016%7D%20%20%3D%20%20-%204)
Divide each side by -2
![\sqrt[4]{4c - 16 } = 2](https://tex.z-dn.net/?f=%20%5Csqrt%5B4%5D%7B4c%20-%2016%20%7D%20%20%3D%202)
raise both side of the equation by power of 4
4c-16=16
move constant to the right and change the sign
4c=16+16
4c=32
THEN DIVIDE BOTH SIDES BY 4
C = 8
Answer:
Y=7.5
Step-by-step explanation:
Answer:
$ 2,600 was invested at 4% and $ 3,600 was invested at 9%.
Step-by-step explanation:
Given that in investing $ 6,200 of a couple's money, a financial planner put some of it into a savings account paying 4% annual simple interest, and the rest was invested in a riskier mini-mall development plan paying 9% annual simple interest, and the combined interest earned for the first year was $ 428, to determine how much money was invested at each rate, the following calculation must be performed:
3000 x 0.04 + 3200 x 0.09 = 408
2500 x 0.04 + 3700 x 0.09 = 433
2600 x 0.04 + 3600 x 0.09 = 428
Therefore, $ 2,600 was invested at 4% and $ 3,600 was invested at 9%.
