Answer:

z=6

Step-by-step explanation:

First you add -8 to both sides. Now the equation is [tex]\frac{z}{-2} \\[/tex]=-3. Now you must multiply both sides by -2, so you get z=6

Which statements are true regarding the sides and angles of the triangle? Select three options. Line segment X Y is the longest side. Angle X is the largest angle. Angle Z is greater than angle Y. Line segment X Z is opposite the largest angle. Line segment X Z is the shortest side.

Answers

Answer:

B. Angle X is the largest angle.

C. Angle Z is greater than angle Y.

E. Line segment X Z is the shortest side.

Step-by-step explanation:

YZ = 2n, XZ = n - 2, XY = n + 4 and n ≥ 5.

YZ - XZ = 2n - (n - 2) = n + 2. but n ≥ 5, hence YZ - XZ = n + 2 ≥ 7.

YZ > XZ

YZ - XY = 2n - (n + 4) = n - 4. but n ≥ 5, hence YZ - XY = n - 4 ≥ 1

YZ > XY

XY - XZ = n + 4 - (n - 2) = 6: XY > XZ

Therefore:

YZ > XY > XZ

The angles are proportional to their opposite sides, hence:

∠X > ∠Z > ∠Y

A. Line segment XY is the longest side.

This is wrong because YZ is the longest side.

B. Angle X is the largest angle.

This is correct. ∠X is the largest angle because it is opposite to the longest side (YZ)

C. Angle Z is greater than angle Y.

This is correct. ∠Z is opposite to the side XY while ∠Y is opposite to the side XZ

D. Line segment XZ is opposite the largest angle.

This is wrong. ∠X is the largest angle which is opposite to the longest side (YZ)

E. Line segment X Z is the shortest side.

This is correct

Answers

Answer:

y = 2

Step-by-step explanation:

Given

7y - (9 + 4y) = - 3 ← distribute parenthesis by - 1

7y - 9 - 4y = - 3 , that is

3y - 9 = - 3 ( add 9 to both sides )

3y = 6 ( divide both sides by 3 )

y = 2

Walter accepted a new job with an annual salary of $47,500. How much can he expect to earn
after paying income taxes?

G $38,675
H $25,650
3 $11,875
Can someone please help with work

Answers

Answer:

F) 35,625

Step-by-step explanation:

Walter is in the 25% range since $47,500 is in-between 36,901 to 89,359

25% = 0.25

47,500 * 0.25 = 11,875

47,500 - 11,875 = $35,625

Find the value of k , if one of the two roots of the equation : x2 + k X – 98 = 0 is double
the additive inverse of the other.
«+
C​

Answers

Given:

[tex]x^2+kx-98=0[/tex]

One of the two roots of the given equation is double  the additive inverse of the other.

To find:

The value of k.

Solution:

Let two roots of the given equation are [tex]\alpha[/tex] and [tex]\beta[/tex].

According to the question,

[tex]\beta=2(-\alpha)[/tex]        (Additive inverse of [tex]\alpha[/tex] is [tex]-\alpha[/tex])

[tex]\beta=-2\alpha[/tex]

If [tex]\alpha[/tex] and [tex]\beta[/tex] are roots of the quadratic equation [tex]ax^2+bx+c=0,[/tex] then

[tex]\alpha+\beta=-\dfrac{b}{a}[/tex]

[tex]\alpha\beta=\dfrac{c}{a}[/tex]

We have,

[tex]x^2+kx-98=0[/tex]

Here, a =1, b=k and c=-98.

[tex]\alpha+\beta=-\dfrac{k}{1}[/tex]

[tex]\alpha-2\alpha=-k[/tex]           [tex][\because \beta=-2\alpha][/tex]

[tex]-\alpha=-k[/tex]

[tex]\alpha=k[/tex]           ...(i)

Now,

[tex]\alpha\beta=\dfrac{c}{a}[/tex]

[tex]\alpha(-2\alpha)=\dfrac{-98}{1}[/tex]          [tex][\because \beta=-2\alpha][/tex]

[tex]-2\alpha^2=-98[/tex]

Divide both sides by -2.

[tex]\alpha^2=49[/tex]

Taking square root on both sides.

[tex]\alpha=\pm \sqrt{49}[/tex]

[tex]\alpha=\pm 7[/tex]

Using (i), we get

[tex]k=\pm 7[/tex]

Therefore, the value of k is either -1 or 1.

The graph of an equation has a minimum y value of 12. This minimum occurs at an x value of 3. What is true of the graph of the equation?

Answers

Answer:

Looking at this graph, you can see that the minimum point of the graph is at y = -3. The second way to find the minimum value comes when you have the equation y = ax^2 + bx + c. If your equation is in the form y = ax^2 + bx + c, you can find the minimum by using the equation min = c - b^2/4a.

Ben was holding a bake sale to raise money for his field trip. He sold cookies for $2 each, muffins for $1 each, and lemonade for $4 a bottle. If he sold 24 cookies, 13 muffins, and 36 bottles of lemonade, how much money did he raise for his field trip? Explain how you found your answer.


​

Answers

Answer: he raised $205

Step-by-step explanation:

cookies: $48 (24x2)

muffins: $13 (13x1)

lemonade: 144 (36x4)

144+13+4=$205

Answer:

205

Step-by-step explanation:

COOKIES: 2x24= 48

MUFFINS: 1x13= 13

LEMONADE: 4x36= 144

144+ 48+ 13= 205

written answer:

The answer is 244 i got this answer by mulitplying how much he sold by the prices he sold by.So i multiplied 2x24 for the cookies and got 48, then i multiplied the muffins 1x13 to get 13.Finally i multiplied 4x36 to get 144 after that, i added all the sums up and i got the answer 205. So Ben raised $205 for his feild trip.

Answers

Answer:

Let's solve for x.

−5x + 4y = 3

Step 1: Add -4y to both sides.

−5x + 4y+ −4y =3+ −4y

−5x = −4y +3

Step 2: Divide both sides by -5.

-5x divided by 5 = -4y+3 divided by -5

x=4/5y + −3/5

C) 4pi(7.4)^3/3
D) 4pi(3.7)^3/3

Answers

i think the answer is A.

the formula to find the volume of a sphere is 4/3 x pi x radius cubed. this means you have to split the diameter in half giving you 3.7 which automatically rules out the answers with 7.4 written in them. now you have to compare A and D but D has 3/3 at the end. this is where you can see that it’s wrong because when you cube you don’t use a fraction.

Answers

Answer:

d is right guy below me is right because this one has a partern

because everytime it was going -2 for y and +1 for x

Answer:

D is the answer

Step-by-step explanation:

For a table to be linear, you can look at the y and x. The equation for slope if ∆y/∆x. Basically, look at the change in y over the change in x. In the last equation, the rule for y cotinues to be -2. X changes as +1. This is a pattern that continues. If you put the y/x, the slope would be -2.

Also, if you look at the other equations, there is no rule. Therefore, the answer is D.
