What is the value of x in y=3x-5 and 6x+3y=15

Mathematics
1 answer:
Ket [755]3 years ago

X=2

You first solve for y on the other equation 6x+3y=15 which will be: y=5-2x

Then you make it one equation: 3x-5=5-2x

Third step is add the -2x with the 3x which is will be 5x.

Fourth: your new equation will be 5x-5=5

Next u would add 5 plus which is 10

Lastly your new equation is 5x=10


I honestly hope this helps !!!!

Ifx <5 and x > C, give a value of c such that there
professor190 [17]

Answer:

For c=5 there are not solutions for the compound inequality

Step-by-step explanation:

we know that

In the compound inequality

x < 5 -----> inequality A

x > c -----> inequality B

The solution of the system of inequalities must satisfy inequality A and must satisfy inequality B

so

If c=5

then

There is no solution that satisfies both inequalities simultaneously.

therefore

For c=5 there are not solutions for the compound inequality

The answer is c
you (4,4) and another point need to be double (2,-5) so the other point needs to add to (4,-10) so 4 + 0 is 4 and 4 + - 14 = 10

#7. What are the values/ how do I do it
Tasya [4]

Answer:

x =2

SK = 21

KY = 13

SY = 34

Step-by-step explanation:

we can see from the picture the following:

SK + KY = SY  equation 1

SK=13x-5    equation 2

KY = 2x+9    equation 3

SY = 36-x     equation 4

using equation 2, equation 3 and equation 4 in equation 1 we have:

13x - 5 +  2x + 9 = 36-x  

15x +4 = 36 - x

15x +x = 36-4

16x = 32

x = 32/16

x= 2

using x as 2 we evaluate it in equation 2, equation 3 and equation 4:

SK=13(2)-5 = 21

KY= 2(2) +9 = 13

SY = 36-2 = 34

Praying someone answers this
Alekssandra [29.7K]
The building is 24 (whatever’s you want ex. Meters, Feet) high. Because 38.7=tan^-1(height/30). Or cos(38.7)=30/hypotenuse. Hypotenuse=30/cos(38.7
