Answer:

y = - 6

Step-by-step explanation:

Locate x = - 3 0n the x- axis, then go vertically down until the line is met. At this point read the value of y from the y0 axis, that is

When x = - 3, y = - 6

Answer:-6

Step-by-step explanation:

Find the linear equation

Slope :(0,-3)(3,0)

0+3/3-0=>1

Y-int=-3

So equation

F(x)=X-3

Now substitute x by -3

Therefore:

F(x)=-3-3

=>-6

Helppp!! Instructions: Find the missing side. Round your answer to the nearest tenth.

natita [175]

Answer:

x ≈ 14.4

Step-by-step explanation:

using the cosine ratio in the right triangle

cos59° = $\frac{adjacent}{hypotenuse}$ = $\frac{x}{28}$ ( multiply both sides by 28 )

28 × cos59° , then

x ≈ 14.4 ( to the nearest tenth )

Which two values of x are roots of the polynomial below? x^2-3x+5

Gemiola [76]

Given:

Polynomial $x^2-3x+5$

To find:

The values of x.

Solution:

$x^2-3x+5=0$

Quadratic equation formula:

$$x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}$

Here $a=1, b=-3, c=5$ .

Substitute the values in the formula, we get

$$x=\frac{-(-3) \pm \sqrt{(-3)^{2}-4 \cdot 1 \cdot 5}}{2 \cdot 1}$

$$x=\frac{3 \pm \sqrt{9-20}}{2}$

$$x=\frac{3 \pm \sqrt{-11}}{2}$

$$x=\frac{3 - \sqrt{-11}}{2} \ \text{and} \ x=\frac{3 + \sqrt{-11}}{2}$

Option E and option F are the roots of the polynomial.

The values of x are $x=\frac{3 - \sqrt{-11}}{2} \ \text{and} \ x=\frac{3 + \sqrt{-11}}{2}$ .

Solve the system using substitution x=3y-11 4x-3y=-26

iragen [17]

Answer:

x=3y-11

then now putting the value of x in second equation

4(3y-11)-3y =26

12y - 44-3y=26

9y=44+26

9y=70

y=70/9

now putting the value of y in 1st equation then

x=3*70/9-11

x=37/3

now checking this is correct or not in 2nd eqn

4*37/3-3*70/9=26

148-70/3=26

26=26
