Answer:

x = 10

y = 20

Step-by-step explanation:

They tell you triangle STY is congruent to triangle DTU, which means sides and angles are equal. (they are mirror images in this case)

YT = DT and ST = UT

3y + 5 = 65

3y = 60

y = 20

Answer:

Step-by-step explanation:

x^2 - 5x + 6 = 0

(x - 2)(x - 3)

So the critical point are x = 2 and x = 3.

The graph of the function opens upwards and pass through the x axis at (2, 0) and (3, 0).

So the required range is the values of f(x) between  when x = 2 and x = 3

that is  2 < x < 3.

Answer:

Step-by-step explanation:

1 Factor {x}^{2}-5x+6x

2

−5x+6.

(x-3)(x-2)<0

(x−3)(x−2)<0

2 Solve for xx.

x=3,2

x=3,2

3 From the values of xx above, we have these 3 intervals to test.

\begin{aligned}&x<2\\&2<x<3\\&x>3\end{aligned}

​

x<2

2<x<3

x>3

​

4 Pick a test point for each interval.

For the interval x<2x<2:

Let's pick x=0x=0. Then, {0}^{2}-5\times 0+6<00

2

−5×0+6<0.

After simplifying, we get 6<06<0, which is false.

Drop this interval..

For the interval 2<x<32<x<3:

Let's pick x=\frac{5}{2}x=

25

​

. Then, {(\frac{5}{2})}^{2}-5\times \frac{5}{2}+6<0( 25) 2−5× 25+6<0.

After simplifying, we get -0.25<0−0.25<0, which is true.

Keep this interval..

For the interval x>3x>3:

Let's pick x=4x=4. Then, {4}^{2}-5\times 4+6<04 2 −5×4+6<0.

After simplifying, we get 2<02<0, which is false.

Drop this interval..

5 Therefore,

2<x<3

2<x<3

Answer

In standard form, the equation is y=4|x+16|+2

Step-by-step explanation:

I included a graph as well

The requried solution of the given expression is y = 6 and -2.

The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.

here,

Simplifying the equation as to form standard form.
4|y - 2| - 16 = 0
4|y - 2| = 16
y - 2 = ± 4,

Now,
y - 2 = 4         ; y - 2 = - 4
y = 6              ; y = -2

Thus, the requried solution of the given expression is y = 6 and -2.

Answer:

5(6-t)

Step-by-step explanation:

in math, product means the "sum" of the equation or the final answer

and in your case, that means 5*6, but then we also have to remember that we're "reducing" or subtracting 't'-

5(6-t)

Answer:

18

Step-by-step explanation:

Let the number be 'x'

Sum of 'x' and 12 = x +12

The product of 8 and the sum of a number and 12 = 8* (x +12)

            = 8*x + 8*12

            = 8x + 96

8x + 96 = 240

Subtract 96 from both sides

8x  + 9 6 - 96  = 240 - 96

8x = 144

Divide both sides by 8

x = 144/8

x = 18

Answer:

216 times the original

Step-by-step explanation:

Volume 1 = 4/3 πr³

volume 2 = 4/3 π(6r)³

v 2 / v 1 = 6³ = 216

When the radius of a sphere is multiplied by 6, the volume is multiplied by 216

Let the radius of the sphere be r

The volume of a sphere of radius, r is calculated as:

v = 4/3 πr³

When multiplied by 6, the radius becomes:

R = 6r

The new volume is then calculated as:

V = 4/3 π(6r)³

Divide both volumes

V/v = 4/3 π(6r)³ / 4/3 πr³

Evaluate the quotient

V/v = 6³

V/v = 216

Hence, when the radius of a sphere is multiplied by 6, the volume is multiplied by 216

Answer:

54.07 inches

Step-by-step explanation:

Given the regression equation :

y = 18.5 + 0.890x

y = pulse rate in beats per minute

x = height

The best predicted pulse rate of a woman who is 65 inches

Put y = 65 in the regression equation :

65 = 18.5 + 0.890x

65 - 18.5 = 0.890x

46.5 = 0.890x

Divide both sides by 0.890

46.5 / 0.890 = 0.890x / 0.890

54.0697 = x

The best predicted pulse rate for a woman wo is 65 inches tall is 54.07 inches

Step-by-step explanation:

x+ 2(7-x) = 11

x+14-2x = 11

-x = -3

x = 3

3+ y = 7

y = 4

x + 2(22-x) = 48

x + 44 -2x = 48

-x = 4

x = -4

-4 + y = 22

y = 26

y = 45-x

x + 2(45-x) = 36

x + 90 -2x = 36

-x = 54

x = -54

-54 + y = 45

y = 99

Answer:

1. x=3 and y=4

2. x=−4 and y=26

3. x=54 and y=−9

Step-by-step explanation:

1. x+y=7;x+2y=11

Step: Solvex+y=7for x:

x+y+−y=7+−y(Add -y to both sides)

x=−y+7

Step: Substitute −y+7 for x in x+2y=11:

x+2y=11

−y+7+2y=11

y+7=11(Simplify both sides of the equation)

y+7+−7=11+−7(Add -7 to both sides)

y=4

Step: Substitute 4 for y in x=−y+7:

x=−y+7  

x=−4+7

x=3(Simplify both sides of the equation)

2. x+y=22;x+2y=48

Step: Solve x+y=22 for x:

x+y+−y=22+−y(Add -y to both sides)

x=−y+22

Step: Substitute−y+22 for x in x+2y=48:

x+2y=48

−y+22+2y=48

y+22=48(Simplify both sides of the equation)

y+22+−22=48+−22(Add -22 to both sides)

y=26

Step: Substitute26 for y in x=−y+22:

x=−y+22

x=−26+22

x=−4(Simplify both sides of the equation)

3. x+y=45;x+2y=36

Step: Solve x+y=45 for x:

x+y+−y=45+−y(Add -y to both sides)

x=−y+45

Step: Substitute−y+45 for x in x+2y=36:

x+2y=36

−y+45+2y=36

y+45=36(Simplify both sides of the equation)

y+45+−45=36+−45(Add -45 to both sides)

y=−9

Step: Substitute−9 for y in x=−y+45:

x=−y+45

x=−(−9)+45

x=54(Simplify both sides of the equation)
