One positive integer is 7 less than twice another. The sum of their squares is 346. Find the integers. should be 2 answers
vovikov84 [41]

Answer:

the two positive integers are x= 15, and y = 11

Step-by-step explanation:

Let the first integer be x

Let the second integer be y

from the problem we can decode the following equations

x=2y-7 ---------------------------- equation 1

x^{2} + y^{2}= 346 -------------------------equation 2

substituting the value of x into equation 2, we have

(2y-7)^{2} + y^{2}= 346 --------------equation 3

expanding, we have

4y^{2}-28y+49+y^{2}=346

5y^{2}-28y-297 = 0

from this, y = 11 or y = -5.4

since our answer is a positive integer, we will have to pick the first value of y which is y = 11

substituting the value of y into equation 1, we have

x= 2(11)-7=15

hence x = 15

Therefore, we have x= 15, and y = 11

these are the two positive integers

Write the equation of the line perpendicular to y=4/3x+1 that passes through the points (-8, 4).
Murrr4er [49]

Answer:

The equation is;

y = -3/4x + 12

Step-by-step explanation:

The general form for the equation of a straight line is;

y = mx + b

where m is the slope and b is the y-intercept

With respect to this question;

4/3 is the slope and 1 is the intercept

If two lines are perpendicular, then the product of their slopes is -1

Mathematically;

4/3 * m2 = -1

m2 = -3/4

So to find the equation of this second line, we use the point slope form

This is;

y-y1 = m(x-x1)

y-4 = -3/4(x + 8)

y- 4 = -3/4x + 8

y = -3/4x + 12

Mrs Smith is completing a mathematics problem. She knows when 6 is added to four times a number, the result is 50. What would be
Lesechka [4]

EXPLANATION:

-To formulate an equation, you must first know what data the exercise gives us to locate them correctly.

data:

-6 that must be added to a number.

-four times a number that is equal to 4x

-a result that is equal to 50

Now with these data we formulate the equation:

\begin{gathered} \text{Equation:} \\ 6+4x=50;\text{  } \end{gathered}

if we solve the equation we have:

\begin{gathered} 6\text{ }+4x=50 \\ 4x=50-6 \\ 4x=44 \\ x=\frac{44}{4} \\ x=-\frac{22}{2} \\ x=\text{ }-11 \end{gathered}
