The interval from -infinity to infinity indicates that all real numbers are in the interval.

Real numbers include fractions, decimals, irrational numbers, etc., while integers do not. Integers are only the whole numbers.

Hope this helps!

5x-2y=-10
Making y the subject of the formula;
5x+10=2y
2y=5x+10
y= $\frac{5}{2} x+5$
The slope is 2.5 or five halves

The sum of the measures of angle S and angle Tis 120°

Step2247 [10]

Answer:

$x=15$

Step-by-step explanation:

We know that the sum of Angle S and Angle T is 120. So:

$\angle S+\angle T=120$

The measure of Angle S is (4x + 30).

And the measure of Angle T is (30).

We want to find the value of <em>x</em>.

By substitution:

$(4x+30)+(30)=120$

Combine like terms:

$4x+60=120$

Subtract 60 from both sides:

$4x=60$

Divide both sides by 4:

$x=15$

Hence, the value of <em>x </em>is 15.
