Step-by-step explanation:

[tex] \star{ \sf{ \: \: \frac{5}{3} + \frac{7}{4}}} [/tex]

Convert the given fractions into like fractions.

To do so, Take the L.C.M ( Least Common Multiple ) of 3 and 4.

To find out the L.C.M of given numbers,

First of all, find the prime factors of each numbers.

3 = 3 × 1

4 = 2 × 2 × 1

Take out the common prime factor i.e 1

Also take out the other remaining prime factors i.e 2 , 2 and 3

Now, multiply those all prime factors and obtain L.C.M

= 1 × 2 × 2 × 3 = 12

L.C.M of 3 and 4 = 12

[tex] \dashrightarrow{ \sf{ \frac{5 \times 4 + 7 \times 3}{12}}} [/tex]

[tex] \dashrightarrow{ \sf{ \frac{20 + 21}{12}}} [/tex]

Add the numbers : 20 and 21

[tex] \dashrightarrow{ \sf{ \frac{41}{12}}} [/tex]

Convert the improper fraction into mixed fraction

[tex] \dashrightarrow{ \boxed{\sf{3 \frac{5}{12} }}}[/tex]

Remember : While performing the addition or subtraction of unlike fractions, you have to express the given fractions into equivalent fractions of common denominator and add or subtract as we do with like fractions. Thus , obtained fractions should be reduced into lowest terms if there are any common on numerator and denominator. But in case of improper fraction, it needs to be deduced on mixed fraction.

Answer:

The answer is

[tex]( \frac{3}{2} \: , \frac{5}{2} ) \: \: or \: \: (1.5 \: \: , \: \: 2.5)[/tex]

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

[tex]M = ( \frac{x1 + x2}{2} \: , \: \frac{y1 + y2}{2} )[/tex]

where

(x1 , y1) and (x2 , y2) are the points

The sum of two numbers, x and y is 14. Twice the first number x and triple the second number y is 63. Find x and y.

Answers

Answer:

x = -21, y = 35.

Step-by-step explanation:

Use the elimination method:

x + y = 14

2x + 3y = 63

Multiply the first equation by -2:

-2x - 2y = -28

Add this to the second equation to eliminate x:

y = 35

So x  + 35 = 14

x = 14 - 35

x = -21.

True or False: If a function crosses an axis at (a,0), this location is known as an x-intercept of the function.

Answers

Answer:

True

Step-by-step explanation:

Given

[tex]Location: (a,0)[/tex]

Required

Does the location represent the x intercept?

The general point form of a function is (x,y)

When y = 0;

This represents that the function crosses the y axis.

And whenever the function crosses the y axis, we have the x intercept of the function

Hence, the statement is true
