Select the equation that represents the line that passes through (1,7) and is parallel to y = 5x + 4

VladimirAG [237]

Answer:

Step-by-step explanation:

it has to have to same slope as the first equation so you have y=5x+b then what you do is plug in the points and solve for b. which gives you 2. so your final equation is y=5x+2

7=5+b

Find the balance in an account with $7,000 principal earning 5% interest compounded quarterly

nadya68 [22]

Answer:

The balance is $\$11,505.34$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=10\ years\\ P=\$7,000\\ r=0.05\\n=4$

substitute in the formula above

$A=\$7,000(1+\frac{0.05}{4})^{4*10}=\$11,505.34$

Line a is parallel to line b, m 6=85 and m 3=2x. Find m 1.

FromTheMoon [43]

The sum of the angles <6 and <3 must be 180. Since <3 and <1 are opposed to the top, their measure are equal. We need then to calculate the measure of angle >3 = 180 - <6 = 180-85=95

m(<1) = 95
