Plz can someone help me show work for these two problems!! 3x + y = 13 2x - y = -1

Alisiya [41]

Answer:

3x +y = 13

Or, x=13-y/3......eqn(i)

Now putting the value of x

2x - y = - 1

Or, 2(13-y/3) - y = - 1

Or, 26 - 2y /3 - y = -1

Or, 26 - 2y - 3y = - 3

Or, 26 - 5y = - 3

Or, - 5y = - 3 - 26

Or,y = - 39/ (- 5)

Or, y = 7.8~

Please help x=10 evaluate f(x) a:24 b :16 C: no solution d :103

OLga [1]

Since $x=10$ we know our function is $f(x)=x^{2}+3$ .

To solve, substitute the given value:
$f(10)=10^{2}+3=100+3=103$

Determine the smallest integer value of x in 5x + 3 ≥ 10

Ivanshal [37]

5x + 3 ≥ 10

3 is adding on the left, then it will subtract on the right

5x ≥ 10 -3

5x ≥ 7

5 is multiplying on the left, then it will divide on the right

x ≥ 7/5

x ≥ 1.4

Then, the smallest integer value of x is 2
