a, b, and c represent three different digits. If you add up all of the six two - digit numbers that can be written with these di

gits, where you don't use the same digit twice in each number, then the sum will be 528. Find these digits.

4 0

Answer:

The answer is 7, 8 and 9. The Two-digit numbers are: ab, ac, ba, bc, ca, cb

The Sum of them is: 10a + b + 10a + c + 10b + a + 10b + c + 10c + a + 10c + b = 528

22a + 22b + 22c = 528

a + b + c = 528/22

a + b + c = 24      The only option of three different digits with the sum of 24 is 7, 8 and 9.

Hope this helps, stay safe, and merry christmas!

A line's graph is shown. Write an equation for the line.​
MAXImum [283]

Answer:

y = 1

Step-by-step explanation:

Given

Attached graph

Required

The graph equation

Pick any two points, we have:

(x_1,y_1) = (1,1)

(x_2,y_2) = (3,1)

Calculate slope (m)

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{1 - 1}{3 - 1}

m = \frac{0}{2}

m = 0

The equation is then calculated using:

y = m(x - x_1) + y_1

This gives:

y = 0* (x - x_1) + 1

y = 1

Hence, the equation is:

y = 1

Which of the statements is true regarding the graphed functions ?
DedPeter [7]
F(x) means the function defined at that x value. It really just means what y value when x is equal to that input. So we can see clearly that A is false. They’re nearly opposite y values. B is also obviously false since the y values aren’t equal. C is the same case, the y values aren’t equal. D is true. When x = -2 for both functions, we can see the y value is the same. They also intercept, so that’s a pretty dead giveaway

Find two mixed numbers or fractions with a quotient of 3.2
sergij07 [2.7K]

Answer:

\frac{32}{10}\\\\\frac{64}{20}\\\\\frac{96}{30}

These all thave the same quotient of 3.2

Step-by-step explanation:

The fractions which are given and and which are also required are called equivalent fraction. In this, the denominator and numerator of both fractions is different, but when you divide the numerator and denominator to get a value, the values of both the fractions are found same.

To find 2 mixed number or fraction with a quotient 3.2.

We can write 3.2 in the fractional form:

3.2 = \frac{32}{10}

Now multiply both the numerator and denominator with 2, we get

\frac{2\cdot32}{2\cdot10}= \frac{64}{20}

which also has the quotient 3.2

Similarly, multiply both numerator and denominator of 32/10 by 3, we get

\frac{3\cdot32}{3\cdot10}=\frac{96}{10}

whici also has the quotient of 3.2

Similarly we can go on to find as many values as we want with the same quotient.
