Is x = 4 a solution to -10 + 5x = -10 - = Yes or no

Mathematics
1 answer:
Aleks [24]3 years ago
3 0

Answer:

no

Step-by-step explanation:

-10 + 5x = -10

Let x = 4 and substitute into the equation

-10 + 5(4) = -10

-10 +20 = -10

10 = -10

This is not true so x=4 is not a solution

If 35 of the 140 cars delivered to a dealer were blue, what percent of the car is blue
maw [93]
If we take 140 to be the 100%, what is 35 off of it in percentage anyway?

\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
140&100\\
35&p
\end{array}\implies \cfrac{140}{35}=\cfrac{100}{p}\implies p=\cfrac{35\cdot 100}{140}

Which function in vertex form is equivalent to f(x) = x2 + x +1?
Alexxandr [17]

Answer:

C

Step-by-step explanation:

Given

f(x) = x² + x + 1

To express in vertex form use the method of completing the square

add/subtract ( half the coefficient of the x- term)² to x² + x

x² + 2(\frac{1}{2})x + \frac{1}{4} - \frac{1}{4} + 1

= (x + \frac{1}{2})² + \frac{3}{4} → C

angle 0 is in quadrant 1 with sin0 = 2/5. Use the Pythagorean identity, sin^2 0 + cos^2 0 = 1, to calculate the value of cos0 as
Gwar [14]
We know that
sin²x+cos²x=1
so 
clear cos x
cos x=(+/-)√[1-sin²x]

in this problem
<span>Angle 0 is in quadrant 1 -----> cos o and sin o are positive
</span>sin o=2/5
cos x=√[1-(2/5)²]----> cos o=√[1-4/25]----> cos o=√[21/25]---> cos o=√21/5

the answer is
cos o=√21/5
