{\huge {\mathfrak {\orange {Answer :}}}}

We have, a = ( - 2) and b = 5

So, a^2 + 3b

= ( - 2)^2 + 3 * 5

= 4 + 15

= 19

➡️ 19 is your answer

That's it..

In mathematics, a rational number is a number such as −3/7 that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Every integer is a rational number: for example, 5 = 5/1.

In mathematics, the irrational numbers are all the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers.

Write the equation of the linear relationship in slope-intercept form, using decimals as needed.
Vedmedyk [2.9K]

Answer:

y = -0.3x + 103

Step-by-step explanation:

✔️Find the slope (b):

Slope = ∆y/∆x

Using, (25, 95.5) and (35, 92.5),

Slope (m) = (92.5 - 95.5)/(35 - 25) = -3/10 = -0.3

✔️Find the y-intercept (b):

Substitute (x, y) = (25, 95.5) and m = -0.3 into y = mx + b

95.5 = -0.3(25) + b

95.5 = -7.5 + b

95.5 + 7.5 = b

103 = b

b = 103

✔️To write the equation, substitute m = -0.3 and b = 103 into y = mx + b

Thus:

y = -0.3x + 103
