What is the equation of a line , in a slope -intercept form , that passes through (5,-3) and has a slope of 2/3? A. y-3= 2/3(x+5

zmey [24]

Ur asking for slope intercept form, but ur answer choices are in point slope form....so I am gonna find the answer in point slope form.

y - y1 = m(x - x1)
slope(m) = 2/3
(5,-3)....x1 = 5 and y1 = -3
now we sub...but pay very close attention to ur signs
y - (-3) = 2/3(x - 5) =
y + 3 = 2/3(x - 5) <=== ur answer in point slope form

Jason is making a fruit salad. He mixes in 3 1/4 cups of orange melon and 2 2/3 cups of green melon. How many cups of melon does

Strike441 [17]

Answer:

5 11/12 cups of melon

Step-by-step explanation:

The cups of melon he puts in the fruit salad is:

Number of cups of orange melon + Number of cups of green melon

= 3 1/4 cups + 2 2/3 cups

3 + 2 + (1/4 + 2/3)

The Least common denominator is 12

5 + (3 × 1 +4 × 2/12)

5 + (3 +8/12)

5 11/12 cups

Therefore, Jason put in 5 11/12 cups of melon in the fruit salad.

Cesar turned in his third research report, his teacher said that he had completed 20%of the reports for the school year, how man

AleksAgata [21]

Answer:

Cesar will be doing 15 research reports during the school year.

Step-by-step explanation:

Given:

Number of research report completed = 3

Percentage of the report completed for school year = 20%

We need to find total number of research report completed during school year.

Solution:

Let the total number of research report completed during school year be 'x'.

Now we can say that;

Number of research report completed is equal to Percentage of the report completed for school year multiplied by total number of research report completed during school year and then divided by 100.

framing in equation form we get;

$3=\frac{20}{100}\times x\\\\3=0.2x$

Dividing both side by 0.2 we get;

$\frac{3}{0.2}=\frac{0.2x}{0.2}\\\\x=15$

Hence Cesar will be doing 15 research reports during the school year.
