6^2 -(8-4) ^2 +7=
pls help I can’t fail math LOL

Answer:

10x + 10y + 7

Step-by-step explanation:

You will have to group like terms, terms that have either the same degree or variable. In this case, we have x, y, and the constant.

9x + x = 10x

2y + 8y = 10y

4 + 3 = 7

Answer:

actual number: 26.6666666667

Step-by-step explanation:

80 divided by 3

Answer:

1. d ≈ 19

2. a ≈ 39.00°

3. x ≈ 37°

Step-by-step explanation:

1) Using sine to find d, recall that sine = opposite side/hypotenuse. So:

[tex]sin(39) = \frac{d}{30}[/tex]

Cross multiply:

d = 30 (sin(39))

d ≈ 19

2) To find the measure of the angle, we can use sine because we have the opposite side and hypotenuse measures. So:

[tex]sin(a) = \frac{18.88}{30}[/tex]

Using the inverse of sine:

[tex]a = sin-1(\frac{18.88}{30})[/tex]

Input into calculator:

a ≈ 39.00°

3) To find the measure of the angle, we can use tangent because we have the opposite side and adjacent side measures. So:

[tex]tan(x) = \frac{300}{400}[/tex]

Using inverse of tangent:

[tex]x = tan-1 (\frac{300}{400})[/tex]

Input into calculator:

x ≈ 37°

Answer:

Around 72.8 inches

Step-by-step explanation:

We are given the infomation that Chris is 185 centimeters tall.

There are 2.54 centimeters in an inch.

185/2.54 = 72.8346 ≈ 72.8

Chris should be around 72.8 inches.

Hope this helps.

Chris should be around 72.8 inches tall.

Here, we have,

given that,

Scott is 72 inches tall and Chris is 185 centimeters tall

We are given the information that Chris is 185 centimeters tall.

now, we know that,

There are 2.54 centimeters in an inch.

Since 1 inch = 2.54 centimeters

all we need to do is to divide 185 by 2.54

i.e. 185/2.54 = 72.8346 ≈ 72.8

The answer will be 72.8.

Chris should be around 72.8 inches.

The correct option will be that S T is congruent to segment W V.

Given the triangles STU and WVX, if the triangje are congruent, then the measure of their sides will be the same.

Since the corresponding angles are congruent, hence the equivalent sides will be:

ST = WV

Su = WX

TU = VX

Based on these, the correct option will be that S T is congruent to segment W V.

Answer:

Step-by-step explanation:

Answer:

15. d) 36

16. b) 20

17. d) 180

18. b) 50

19. c) 360

20. b) 60

Step-by-step explanation:

To find the number of sides a polygon has giving an interior angle, use the equation:

(number of sides - 2)*180/(number of sides) = measure of interior angle

15. (n = number of sides)

((n-2)*180)/n = 170

180n-360 = 170n

10n = 360

n = 36 (d)

16. (n = number of sides)

((n-2)*180)/n = 162

180n-360 = 162n

18n = 360

n = 20 (b)

17. The sum of the interior angles of a triangle is always 180 (d)

18. 180-60-70 = 50 (b)

19. The sum of the interior angles of a quadrilateral is always 360 (c)

20. 360-120-90-90 = 60 (b)

Answer:

y = x-2

Step-by-step explanation:

Because y is always 2 less than x the second equation is correct.

5 = 7-2

6 = 8-2

And so on.

=========================================================

Work Shown:

The given equation y = (1/5)x+4 is in the form y = mx+b with m = 1/5 as the slope.

Apply the negative reciprocal to this slope to go from 1/5 to -5/1 or -5.

The original slope is 1/5 and the perpendicular slope is -5. Note the two slopes multiply to -1. This applies to any pair of perpendicular lines as long as neither line is vertical.

---------

We'll use m = -5 as the slope and (x,y) = (5,-4) to find the y intercept

y = mx+b

-4 = -5*5+b

-4 = -25+b

-4+25 = b

21 = b

b = 21

The y intercept of the perpendicular line is b = 21

With m = -5 and b = 21, we go from y = mx+b to y = -5x+21 which is the equation of the perpendicular line.

Answer:

[tex]y=10x+15[/tex]

Step-by-step explanation:

We want the equation of a line with a slope of 10 and passes through (-4, -25).

We can use the point-slope form given by:

[tex]y-y_1=m(x-x_1)[/tex]

Where m is the slope and (x₁, y₁) is a point.

So, we will substitute 10 for m and (-4, -25) for (x₁, y₁):

[tex]\displaystyle y-(-25)=10(x-(-4))[/tex]

Simplify:

[tex]y+25=10(x+4)[/tex]

Distribute:

[tex]y+25=10x+40[/tex]

Subtract 25 from both sides:

[tex]y=10x+15[/tex]

And we have our equation.

Step-by-step explanation:

Given:

The system of equations is

[tex]y=2x-5[/tex]

[tex]2y-4x=?[/tex]

To find:

The missing value for which the given system of equations have infinitely many solutions.

Solution:

Let the missing value be k.

We have,

[tex]y=2x-5[/tex]

[tex]2y-4x=k[/tex]

Taking all the terms on the left side, the given equations can be rewritten as

[tex]-2x+y+5=0[/tex]

[tex]-4x+2y-k=0[/tex]

The system of equations [tex]a_1x+b_1y+c_1=0[/tex] and [tex]a_2x+b_2y+c_2=0[/tex] have infinitely many solutions if

[tex]\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}=\dfrac{c_1}{c_2}[/tex]

We have,

[tex]a_1=-2,b_1=1,c_1=5[/tex]

[tex]a_2=-4,b_2=2,c_2=-k[/tex]

Now,

[tex]\dfrac{-2}{-4}=\dfrac{1}{2}=\dfrac{5}{-k}[/tex]

[tex]\dfrac{1}{2}=\dfrac{1}{2}=\dfrac{5}{-k}[/tex]

[tex]\dfrac{1}{2}=\dfrac{5}{-k}[/tex]

On cross multiplication, we get

[tex]-k=10[/tex]

[tex]k=-10[/tex]

Therefore, the missing value is -10.
