When you have -13+20 how exactly did you get 7?

2 answers:

7 0

Imagine a number line. 0 is the start and it either goes to the right which is higher or to the left which is lower. -13 goes to the left since all negative numbers are at the left of 0. So you basically count up from -13 which is -12,-11,-10,-9,-8,-7,-6,-5,-4,-3,-2,-1, and 0. We just went 13 places up, so only 7 more to go. Counting up from 0 seven places is 7. So the answer is seven. Keep practicing and it will get easier and make sense.

Answer: you start with a -13 right? well then you add a positive 20 which will then equal to 7 if you were adding a -20 then you get -33

The ratio of Aziz's money to Osman's money was 2:1 at first. After Aziz spent $10 ratio became 4:3. How much money did each boy

Dvinal [7]

Answer:

Aziz's money was $30

Osman's money was $15

Step-by-step explanation:

Let

x-----> Aziz's money at first

y-----> Osman's money

we know that

$\frac{x}{y}=\frac{2}{1}$

$x=2y$ ------> equation A

$\frac{x-10}{y}=\frac{4}{3}$ -----> equation B

substitute equation A in equation B and solve for y

$\frac{2y-10}{y}=\frac{4}{3}\\ \\6y-30=4y\\ \\6y-4y=30\\ \\2y=30\\ \\ y=15$

Find the value of x

$x=2(15)=30$

therefore

At first

Aziz's money was $30

Osman's money was $15

What is the slope of a line that passes through (-4,-13) and (19,11)?

raketka [301]

We can find the slope from the two given points using the standard formula:
$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$
$m=\frac{11-(-13)}{19-(-4)}$
$m=\frac{24}{23}$

Is 1.2 less than or higher than 1.5

Olenka [21]

1.2 is less than 1.5

If you cancel out 1 from both numbers you're left with .2 and .5

Multiply both by 10 and get 2 and 5.

Obviously 2 is less than 5.

Answer:

f(x) = x

Step-by-step explanation:

note : slope is positive 1, so the x term must be positive

also note the graph intersects the curve at y = 0, which means that they y-intercept is zero .

if we substitute this into the general equation for a line

y = mx + b, where m = +1 and b = 0,

we get y = x

or f(x) = x (in function form)
