Step-by-step explanation:

Read through the problem and set up a word equation — that is, an equation that contains words as well as numbers.

Plug in numbers in place of words wherever possible to set up a regular math equation.

Use math to solve the equation.

Find the length of side xz give your answers to 3 significant figures

aleksandrvk [35]

Answer:

XZ ≈ 14.4 cm

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos29° = $\frac{adjacent}{hypotenuse}$ = $\frac{ZY}{XZ}$ = $\frac{12.6}{XZ}$

Multiply both sides by XZ

XZ × cos29° = 12.6 ( divide both sides by cos29° )

XZ = $\frac{12.6}{cos29}$ ≈ 14. 4 ( to 3 sig. figs )

Write the equation of the line that passes through the given point and is perpendicular to the given line

Bumek [7]

Answer:

y = 5

Step-by-step explanation:

<u>The line x = 3 is parallel to y- axis, the perpendicular line is going to be parallel to x- axis and will have an equation:</u>

y = a

<u>Since it passes through the point (-2, 5), it will have a = 5:</u>

y = 5 is the line we need

What’s the equation of the line that passes through (2,3) and is parallel to the line 12x-5y=2

TiliK225 [7]

12x-5y=2

-5y=2-12x

y=-2/5+12/5x

should know the m=12/5

and (2,3) bring them to the line equation:

3=12/5x2+b

6/5+b=3

b=3-6/5

b=9/5

y=12/5x+9/5

Which means the answer is not in the choices.

Solve x^2+4x+8. What is the vertex?

LenKa [72]

Answer:

$(-2,4)$

Step-by-step explanation:

Well to start with there is a vertex formula which is $-\frac{b}{2a} =h\\$ , $f(h)$

Your initial equation is $x^2+4x+8$ where $ax^2+bx+c$ . So you would plug in your numbers $-\frac{4}{2(1)}$ $=-\frac{4}{2} =-2$ we know know that $h=-2$ so plug in h in $f(-2)$ which would be (-2)^2+4(-2)+8 = 4-8+8 = 4 which would make the vertex $(-2,4)$

(x - 11) (4x + 1) what is x

Evgesh-ka [11]

Answer:x=-43

Step-by-step explanation:

To expand (x-11)(4x+1) to get x

x^2+x-44x-11

x^2-43x-11

So x=-43
