Equation for y and what if equals too
katen-ka-za [31]

The answer is y = 35x + 20.

In order to find this, start with two ordered pairs. For the purpose of this problem, we'll use (1, 55) and (2, 90). Now we use the slope formula to find the value next to x in the equation.

m(slope) = (y2 - y1)/(x2-x1)

In this equation (x1, y1) is the first ordered pair and (x2, y2) is the second. Plug in to the equation and solve.

m = (90 - 55)/(2 - 1)

m = 35/1

m = 35

Now that we have the slope, plug that into the equation along with either point to find the intercept (the last number).

y = mx + b

55 = 35(1) + b

55 = 35 + b

20 = b

Now that we have the slope and intercept, we can use each to fill in those blanks.

y = 35x + 20

Anita got 4 problems wrong on a test of 36 questions. what percent of the questions did she get correct
pickupchik [31]
The answer would be about 89% 
to solve this problem first you would have to subtract 4 from 36 to get 32 because you want to know how many she got right first .
so you put 32 over 36 ( the number she got right over the total number of questions ) and n ( the number you don't know yet ) over 100 . that will be the percent .
next all you have to do is cross multiply 32 times 100 and 36n , to get 3200 and 36n . 
now you have to divide 3200=36n by 36 so you get n by its self but you have to divide on both sides of the equal sign .
when you divide you will then get 88 with a lot of remainder 8's so you would just round up to 89 .
finally you know n = 89% so she got 89% of her questions right .

Which answer choice shows the decimals in order from least to greatest
djverab [1.8K]

Answer:

D.1.121, 1.21, 1.432, 1.53

Step-by-step explanation:

Look at it as money:

$1.12

$1.21

$1.43

$1.53

We know that D states the money from least to greatest.

Or

We can convert them to fractions by Decimals can be written in fraction form. To convert a decimal to a fraction, place the decimal number over its place value. For example, in 0.6, the six is in the tenths place, so we place 6 over 10 to create the equivalent fraction, 6/10. If needed, simplify the fraction.

Irene received $425 in annual interest on a principal investment sum of $5,000. What was the simple interest rate for his return
GalinKa [24]
Irene received 425 dollars as interest rate for his principal investment which is 5000 dollars.
Let's solve for the interest rate:
=> 425 / 5000 dollars = 0.085
=> 0.085 * 100% = 8.5% 
Thus the simple interest or annual interest to her investment is 8.5%
