Answer:

Choice B is correct.

Explanation:

The given equation is -r+5(r+2)=-10

Put r=-5 into the above equation

-(-5)+5(-5+2)=-10

5+5(-3)=-10

5-15=-10

-10=-10

Right and left side of above equation is equal by putting r=-5 so it is true statement.

Help me with this pls
Dvinal [7]

Answer:

C

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

6x + 10y = 8 ( subtract 6x from both sides )

10y = - 6x + 8 ( divide each term by 10 )

y = - \frac{6}{10} x + \frac{8}{10} = - \frac{3}{5} x 6 + \frac{4}{5} ← in slope- intercept form

with slope m = - \frac{3}{5} → C

An air traffic controller is tracking two planes.To start Plane A was at an altitude of 990 meters and plane B was at an altitud
soldi70 [24.7K]

The equation representing when the two planes would be at the same altitude is 9x=486

<h3>In terms of mathematics, what is an equation?</h3>

Equation: A declaration that two expressions with variables or integers are equal. In essence, equations are questions, and attempts to systematically identify the solutions to these questions have been the driving forces behind the creation of mathematics.

From (a) we get that: Altitude of Plane A = 990-18x

Altitude of Plane B = 1476-27x

make 890 - 18x = 1476-27x

-18x+27 x = 1476-890

9x=486

X= 54

so pass 54 seconds will the two plane at the same altitude.
