Answer:

$3x+4=5x-10$

Step-by-step explanation:

we know that

The solution of the linear system of equations is the intersection point both graphs

using a graphing tool

we have

$y=3x+4$ ------> equation A

$y=5x-10$ ------> equation B

To find the solution equate the equation A and equation B

$3x+4=5x-10$

Solve for x

$5x-3x=4+10$

$2x=14$

$x=7$

Find the value of y

$y=3x+4$ ------> $y=3(7)+4=25$

the solution is the point $(7,25)$

see the attached figure to better understand the problem

Thank you for posting your question here at brainly. Feel free to ask more questions.
The best and most correct answer among the choices provided by the question is 3x + 4 = 5x – 10. 

Hope my answer would be a great help for you.

The answer is 43-30x because you always add the parenthesis first which now you have 18+25-10x3 then you calculate the product 18+25-30x. after all that you then add all the numbers and get 43-30x. hope this helps

The solution to a system of two linear equations is (4, -3). One equation has a slope of 4. The slope of the other line is the n

astraxan [27]

Answer:

Hello,

First equation is false

Second equation is true

Step-by-step explanation:

(4,-3) is a point of the line y=4x-19 since

-3=?4*4-19

-3=-3

(4,-3) is not a point of the line y=1/4x-2 since

-3=? 1/4*4-2

-3=? 1-2

-3≠-1

I have written that because it is difficult for me to understand

"the negative reciprocal of the slope of the first"

the negative reciprocal of 4 should be -1/4.

Equation y=1/4x-2 is false.

What is the equation of the line that is paralle to y=3x-8 and passes thur the point (4,-5)

Brrunno [24]

Answer:

The equation is-: y=3x

Step-by-step explanation:

$\large\displaystyle\text{$\begin{gathered} \sf{Substitute \ the \ values \ into \ the \ formula \ y-y_1=m(x-x_1)} \\ \sf {parallel \ lines \ have \ same \ slopes, \ thus} \\ \sf{slope \ of \ the \ 2nd \ line = 3}\\ \sf{now \ substitute \ the \ values} \\ \sf {y-(-5)=3(x-4)}\\ \sf{y+5=3(x-4) (It's \ Point-Slope\;Form, \ see \ below \ for \ slope-intercept)}\\ \sf {y+5=3x-12} \\ \sf{y=3x-12-5} \\ \sf{y-3x-17} \end{gathered}$}}$

While Al was staying overnight on vacation with his friends his only expenses were for food. Al spent $7.52 on lunch, $9.74 on d

Serggg [28]

Answer:

$25.10

Step-by-step explanation:

lunch=$7.52

dinner=$9.74

breakfast=$5.16

money left=$2.68

make total money he began with ‘x’

to find the total money he began with it will be

x-lunch+dinner+breakfast=money left

x-$7.52+$9.74+$5.16=$2.68

x-$22.42=$2.68

x=$2.68+$22.42

x=$25.10
