What's 4x + 3y = 6 4x - y = 2​
emmainna [20.7K]

Answer:

Step-by-step explanation:

4x + 3y = 6 -----------------(I)

4x - y =2 ---------------------(II)

Multiply (II) by (-1) and  then add

(I)                4x + 3y = 6

II) *(-1)      <u>  - 4x + y  = - 2  </u> {Now add, x will be eliminated}

                         4y = 4

                           y= 4/4

y= 1

Plugin y =1 in equation (I)

4x +3*1 = 6

4x + 3 = 6

      4x = 6- 3

      4x = 3

        x = 3/4

Find the area of the figure <br> A)75in^2<br> B)70in^2<br> C)65in^2<br> D)80in^2
katrin2010 [14]

Answer: B, 70 inches.

Step-by-step explanation:

Let's start slow and go shape by shape.

Based on the information we have, we know that the length for the rectangle is 8 inches by 7 inches. 8*7 = 56, so we have one of the answers.

Next, we do the triangle. Based on the information we have, we know that the triangle is 4 inches by 7 inches divided by 2. 4*7 = 28 \frac {28}{2} = 14

Adding 14 and 56, we got the answer to be B, 70 inches.

Write the equation of a line that is perpendicular to the given line that passes through the given point.
ipn [44]
<h2>Answer:</h2>

First we must find the opposite-reciprocal of the original slope.

current slope: \frac{7}{3}

new slope: -\frac{3}{7}

Using the new slope and the given point, we will plug them into slope-intercept form and solve for b, the y-intercept.

9 = -\frac{3}{7}(-4) + b\\\\9 = \frac{12}{7} + b\\\\-\frac{51}{7} = b

The y-intercept is -\frac{51}{7}.

Now, we can write the formula for the new line.

Slope-intercept form: y = -\frac{3}{7}x - \frac{51}{7}

Point-slope form: y - 9 = -\frac{3}{7}(x + 4)
