Answer:

x=6

Step-by-step explanation:

5(x-1) + 3x = 7x + 1

Distribute

5x -5 +3x = 7x+1

Combine like terms

8x -5 = 7x+1

Subtract 7x from each side

8x- 7x -5 = 7x-7x+1

x-5 =1

Add 5 to each side

x-5+5 = 1+5

x=6

Answer:

x=12

Step-by-step explanation:

5x - 5 + 3x = 7x + 7

8x - 5 = 7x + 7 ( subtract 7x from both sides )

x - 5 = 7 ( add 5 to both sides )

x = 12

A farmer is designing a field for his new horse. In order for the field to fit into his farm, the angle θ must be less than 40◦,

Answer:

The field will not fit

Step-by-step explanation:

To find the angle, we will use cosine rule;

c² = (a² + b² - 2abcosC)

C in this case is θ

Thus;

15² = (8² + 20² - 2(8 × 20)cos θ)

225 = (64 + 400 - 320cos θ)

464 - 225 = 320cos θ

cos θ = 239/320

θ = cos^(-1) 0.7469

θ = 41.68°

Thus angle is not less than 40° as recommended. Thus, the field will not fit.

What point slope form equation could be produced with the points(-3,-6)and (3,-3)

Irina-Kira [14]

Answer:

y+6=1/2(x+3)

Step-by-step explanation:

Hi there!

We want to find the equation of the line in point-slope form that passes through (-3, -6), and (3, -3)

Point-slope form is given as y- $y_{1}$ =m(x- $x_{1}$ ) where ( $x_{1}$ , $y_{1}$ ) is a point and m is the slope

We don't know the slope of the line, so let's find it

The formula for the slope (m) calculated from two points is $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ , where ( $x_{1}$ , $y_{1}$ ) and ( $x_{2}$ , $y_{2}$ ) are points

We have two points, but let's label their values to avoid any confusion

$x_{1}$ =-3

$y_{1}$ =-6

$x_{2}$ =3

$y_{2}$ =-3

Now substitute into the formula (remember: the formula has SUBTRACTION)

m= $\frac{-3--6}{3--3}$

simplify

m= $\frac{-3+6}{3+3}$

m= $\frac{3}{6}$

m=1/2

So the slope of the line is 1/2

Now that we have everything needed for point-slope form (a point and the slope), substitute the values into the formula (remember: the formula has SUBTRACTION)

y- $y_{1}$ =m(x- $x_{1}$ )

y--6=1/2(x--3)

simplify

Hope this helps!
