Greg borrows $1975 at a simple interest rate of 5% for 3 years. Linda borrows $1975 at a simple interest rate of 4.5% for years.
weqwewe [10]

Answer:

Greg pays more interest than Linda

He pays $17.45 more

Step-by-step explanation:

Greg

P=$1975

R=5%=0.05

T=3 years

Simple interest=P×R×T

=$1975×0.05×3

=$296.25

Linda

P=$1975

r=4.5%=0.045

n=1

t=3

Linda's Interest is compounded once per period, so we this formula

Compound Interest =P(1+r)^t

=$1975(1+0.045)^3

=$1975(1.045)^3

=$1975(1.141166125)

=$2,253.80

Interest paid=$2,253.80-$1975

=$278.8

Determine the equation of the line given by the graph.
Zolol [24]

Answer:

We can tell by the graph that it has a positive slope. The

y-intercept is at positive 4. Trying to find the next whole number intercept point will be at (-2,0). Count up and over from that point to the y-intercept point, and put it in rise over run form... 5/2 (up 5, over 2). Now apply these known variables into the slope intercept form: y = mx + b.

The final answer is: y = (5/2)x + 5

M is the slope and B is the y-intercept.

NEED HELP ASAP it's geometry
san4es73 [151]

Answer:

  see the attachment

Step-by-step explanation:

It helps to follow along the proof and consider how you get from here to there.

In the 5th line, we have a sum in symbols.

In the 7th line, we have an expression with a number on the right side, and a statement that says we got there by subtraction.

Then we expect line 6 to have a sum with numbers whose difference is 40°. (That eliminates the 3rd and 4th choices.)

The way you get from an expression with symbols to an expression with numbers is to make a <em>substitution</em> of numbers for symbols. Hence the appropriate choice is the one shown below.
