Answer:

Step-by-step explanation:

Let's solve your equation step-by-step.

75+50x=25+70x

Step 1: Simplify both sides of the equation.

50x+75=70x+25

Step 2: Subtract 70x from both sides.

50x+75−70x=70x+25−70x

−20x+75=25

Step 3: Subtract 75 from both sides.

−20x+75−75=25−75

−20x=−50

Step 4: Divide both sides by -20.

−20x

−20

−50

−20

x= 5/2

Write the equation of the line that passes through the given lines (0,-2) and (4,1)

Gala2k [10]

Answer:

y = 3/4x - 2

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step 1: Define

(0, -2) y-intercept

(4, 1) random point

Step 2: Find slope m

$m=\frac{1-(-2)}{4-0}$

$m=\frac{1+2}{4}$

$m=\frac{3}{4}$

y = 3/4x + b

Step 3: Write linear equation

y = 3/4x - 2

Vika [28.1K]

Answer:

49/4

Step-by-step explanation:

x^2 + 7x = 4

Take the coefficient of x

Divide by 2

7/2

Square it

(7/2) ^2 = 49/4

Add this to each side

x^2 + 7x +49/4= 4+49/4
