Answer:

If segment AB is congruent to segment DE, then segment DE is congruent to segment AB.

This is the same as if a=b then b=a! which property does that sound like?

Step-by-step explanation:

4. 3x + 4=35, well 3x+4-4=35 -4 -> 3x= 35-

4, which property subtracts from both sides?

8. it's already proven! what else is left but to use it! A property is not something in need of proof, it's the very basic stuff we start off with! A conjuncture is still not proven only thought to be true. That leaves 2.

9. if i give u the answer to this one then you won't get much out of it! so either i give you the answer or you get it yourself, those are the conditions.

10. p --> q, well we know p OR q is not it because OR is a U P AND q is not it because OR is a U

so it must be implies!

But is it p implies q or is it q implies p.

Hmmmm...i wonder.. which way does the arrow point from the st to the 2nd.

12. The statement is P then Q Inverses is not P the Q Inverse is not Q converse is Q the P

Contraceptive is not Q then not P.

13. If and only if, i will give you the answer if and only if you only look it up on the internet.

Did i put one condition on you to do it or two?

Indirect proof is a type of proof in which a statement to be proved is assumed false and if the assumption leads to an impossibility, then the statement assumed false has been proved to be true.

WILL GIVE BRAINLIST SOON AS I CAN I DONT UNDERSTAND THIS, PLZ HELP

allochka39001 [22]

Answer:

b = 7 $\sqrt{3}$

Step-by-step explanation:

Since the triangle is right use the tangent ratio to solve for b

and the exact value

tan30° = $\frac{1}{\sqrt{3} }$ , thus

tan30° = $\frac{opposite}{adjacent}$ = $\frac{7}{b}$ and

$\frac{7}{b}$ = $\frac{1}{\sqrt{3} }$ ( cross- multiply )

b = 7 $\sqrt{3}$

(a) Derive an equation of the line passing through the points A(0, 545) and B(4, 726). (Let t be the independent variable and y

a_sh-v [17]

Answer:

The equation of the line is $y=45.25t+545$

Step-by-step explanation:

The general for of a line is:

$y=mt+n$ (1)

where:

$m$ is the slope of the line and $m$ is the intercept with the axis of the dependent variable, $y$ in this case.

In order to obtain the value of the slope ( $m$ ) we can use the corresponding slope formula:

$m=\frac{y_{2}-y_1 }{t_2-t_1}$ (2)

where $t_1, t_2, y_1$ and $y_2$ are the corresponding coordinates of the given points. In this case:

$t_1=0\\t_2=4\\y_1=545\\y_2=726\\$

Substituting these values in equation (2) we obtain:

$m=\frac{726-545}{4-0}=\frac{181}{4}=45.25\\m=45.25$

Hence, the line equation is now:

$y=45.25t+n$ (3)

Now to obtain the value of $n$ you can follow two options:

You can substitute one of your points, $A$ or $B$ , in equation (3). In this way, you will obtain an equation where the variable is $n$

Note that for this question, it is easier to select point A because of having the independent variable equals to zero $t=0$ . Hence, substituting point A in equation (3):

$45.25*0+n=545\\n=545$

Therefore, the line equation is: $y=45.25t+545$

The second option to find $n$ is to think of the meaning of the <em>intercept</em>. The <em>intercept </em>of a line is defined as the point in which the line crosses the axis of the dependent variable, which also means that the value of the independent variable for this point is zero. From this, we could have automatically said that $n$ is equal to $545$ .

See the attachment for a plot of the line.

Write an equation where the variable is divided by a number, and a solution is -4/5

MrMuchimi

Answer:

x/-5

Step-by-step explanation:

Just divide by 5 and the denominator will be 5 meaning x would have to be 4.

Make sure your 5 is negative so the whole equation also ends up negative. x/-5=-4/5
