x=
Answer:
x = 3.5
Step-by-step explanation:
[tex] \triangle DEF \sim \triangle XYZ\\\\
\therefore \frac{DE}{XY} =\frac{DF}{XZ} \\\\
\therefore \frac{5}{7.5} =\frac{7}{3x} \\\\
\therefore 3x = \frac{7.5\times 7}{5} \\\\
\therefore x = \frac{7.5\times 7}{3\times 5} \\\\
\therefore x = \frac{52.5\times 7}{15} \\\\
\therefore x = 3.5[/tex]
Step-by-step explanation:
If [tex]\triangle[/tex]DEF~[tex]\triangle[/tex]XYZ
[tex]\tt{\dfrac{DE}{XY}=\dfrac{EF}{ZY}=\dfrac{DF}{XZ} }[/tex]
According to the question
[tex]\tt{\dfrac{5}{7.5}=\dfrac{3}{4.5}=\dfrac{7}{3x} }[/tex]
[tex]\tt{\dfrac{3}{4.5}=\dfrac{7}{3x} }[/tex]
[tex]\tt{ 9x=4.5×7}[/tex]
[tex]\tt{ 9x=31.5 }[/tex]
[tex]\tt{ x=\dfrac{22.5}{9} }[/tex]

Guys so it says pick which one is true and!!! I can’t really find out now there is four more left thank you to the people who are helping
Answer:
Your answer is
B. C. And. E
Hope it will help :)❤
is this right? Whats the answer to C?
Answer:
a. Multiplication property of equality
b. Distributive property
c. addition property of equality
Step-by-step explanation:
The first one is wrong because you are multiplying the 2 on both sides to make it equal. There was nothing that they substituted for.
The second one will be the distributive property not the subtraction property of equality. They distributed the 2 into the [tex]\frac{1}{2}x[/tex] and the [tex]-5[/tex]. So that clears up that this step was the distributive property.
This one will be the addition property of equality because when you have a negative number you do the inverse so they added the 10 on both sides. Therefore it's the addition property of equality.

Answer:
slope=1/2
the given point=(0, 13/2)
Step-by-step explanation:
change the equation to the y=mx+b format
y-8=1/2(x-3)
y=1/2x-3/2+8
y=1/2x+13/2
m=slope
1/2=slope
given point(y-intercept)= the constant
given point=13/2

Assuming no variable equals 1 or 0, which of the following statements is always False?
ОООО
1(x) = 1
0(x) = 0
x + y = y + x
a(b + c) = ab + ac
Given:
No variable equals 1 or 0.
To find:
The statements which is always False.
Solution:
According to identity of multiplication,
[tex]1(x)=x[/tex]
For x=2,
[tex]1(2)=2\neq 1[/tex]
So, the statement [tex]1(x)=1[/tex] always false because no variable equals 1 or 0.
Multiplication property of zero,
[tex]0(x)=0[/tex]
Commutative property of addition,
[tex]x+y=y+x[/tex]
Distributive property of multiplication over addition,
[tex]a(b+c)=ab+ac[/tex]
No variable equals 1 or 0. So, all the statements in options B, C, D are always true.
Therefore, the correct option is A.

The domain is the function defined on your x-axis.
It starts from 5 and includes 5
so the domain is x[tex]\geq[/tex]5
Carlos wants to rent a car for the particular car you on gentle rental charges 185 per week plus $0.25 per mile driven rental charges a flat fee of 275 per week what is the number of miles driven so that rented from dental rental cause carlos less than renting from rental giant
Answer:
The indifference point is 360 miles.
Step-by-step explanation:
Giving the following information:
Rental 1:
Total cost= 185 + 0.25*x
x= miles driven
Rental 2:
Total cost= $275
Now, we need to equal both formulas and isolate x:
185 + 0.25x = 275
0.25x = 90
x= 90/0.25
x= 360
The indifference point is 360 miles.

Back in ye olden days, cell phone companies charged for texting. A cell phone company charges 10 cents per text message if a customer sends up to 100 messages per month, 8 cents for 101-200 messages, and 6 cents for 201-300 messages. If today is the last day of the month, and you've sent 200 texts, is it worth it to send 1 more text message?
Answer: It is worth it.
Step-by-step explanation:
If a customer sends 101 - 200 texts in a month, they get charged 8 cents per text.
If they send 201 - 300, they get charged 6 cents per month.
If you have sent 200 texts, your charge for the month will therefore be:
= 200 * 8
= $16.00
If you send the 201th text, you will be charged 6 cents per text. Total charge would be:
= 201 * 6
= $12.06
If you send 1 more text, it will be worth it because you will save:
= 16 - 12.06
= $3.94

24. Find f'(x) for f(x) = ax2 + bx.
Answer:
f'(x) = 2ax + b
Step-by-step explanation:
Differentiate each term using the power rule
[tex]\frac{d}{dx}[/tex] (a[tex]x^{n}[/tex] ) = na[tex]x^{n-1}[/tex]
Given
f(x) = ax² + bx , then
f'(x) = 2a[tex]x^{2-1}[/tex] + b[tex]x^{1-1}[/tex]
= 2ax + b[tex]x^{0}[/tex] ( [tex]x^{0}[/tex] = 1 )
= 2ax + b
