Step 2: Solve for a
Combine like terms (a): 7a + 42 + 8 < -10 + 13a - 6Combine like terms: 7a + 50 < 13a - 16[Subtraction Property of Equality] Subtract 7a on both sides: 50 < 6a - 16[Addition Property of Equality] Add 16 on both sides: 66 < 6a[Division Property of Equality] Divide 6 on both sides: 11 < aRewrite: a > 11Here we see that any value a greater than 11 would work as a solution to the inequality.

Bigcity United played thirty games last season. They won 60% of these. How many games did they lose?
Answer:
Bigcity United lost 12 games.
Step-by-step explanation:
Since you know the percentage of games Bigcity United won, first you need to determine the percentage of games that they lose by subtracting the percentage of games they won from 100%:
100%-60%=40%
Now, you know that they lost 40% of the games and you can calculate 40% of the number of games they played last season:
30*40%=12
According to this, the answer is that Bigcity United lost 12 games.

A pet store has 96 pets ( dogs, cats, birds) for sale. There are 3 more dog than cats. There are 9 less birds than cats. How many of each type of pet are in the shop?
Answer:
Cats = 34
Dogs = 37
birds = 25
Step-by-step explanation:
Let :
c = cats
d = dogs
b = birds
from the question, the following equation can be gotten
d = 3 + c eqn 1
b = c - 9 eqn 2
c + d + b = 96 eqn 3
substitute for b and d in equation 3
3 + c + c - 9 + c = 96
3c - 6 = 96
3c = 102
c = 34
Substitute for d in eqn 1
d = 3 + 34 = 37
Substitute for b in eqn 2
34 - 9 = 25

The domain (input values) of the cosine function is:
A. all negative and positive angle measures.
B. angle measures less than 2 π π radians.
C. angle measures less than 90°.
D. angle measures between 0 and π π radians.
* I can’t miss anymore please help*
Answer:
all negative and positive angle measures.
Step-by-step explanation:
The domain of the cosine function is: all negative and positive angle measures.
What is domain of a function?"It is a set of all possible input values for which a function is well defined."
We know,
A cosine function i.e., f(x) = cos(x) is defined for any real value of x.
This means, the domain of the cosine function is, all negative and positive angle measures.
Therefore, the correct answer is option (A).

You can see how many standard deviations a score is from the mean of the distribution for a raw score or a z-score is by looking at the corresponding z-score.
Answer:
True
Step-by-step explanation:
Z-score may be defined as a position of the raw score in regard to the distance from its mean when it is measured in the units of standard deviation. Z-score is considered as positive, when the values is above the mean. And when it is below the mean, it is considered as negative.
Another name of a z-score is standard score. Z-score can be measured using the relation :
[tex]$z=\frac{x-\mu}{\sigma}$[/tex]
where, z = z-score
x = raw score
μ = population mean
σ = population standard deviation
Thus from the formula we can see how many standard deviation the score is from a men of the distribution by looking at the corresponding z-score.
For the rhombus below, find the measure of angles 1,2,3 and 4.
Answer:
∠1 is 33°
∠2 is 57°
∠3 is 57°
∠4 is 33°
Step-by-step explanation:
First off, we already know that ∠2 is 57° because of alternate interior angles.
Second, it's important to know that rhombus' diagonals bisect each other; meaning they form 90° angles in the intersection. Another cool thing is that the diagonals bisect the existing angles in the rhombus. Therefore, 57° is just half of something.
Then, you basically just do some other pain-in-the-butt things after.
Since that ∠2 is just the bisected half from one existing angle, that means that ∠3 is just the other half; meaning that ∠3 is 57°, as well.
Next is to just find the missing angle ∠1. Since we already know ∠3 is 57°, we can just add that to the 90° that the diagonals formed at the intersection.
57° + 90° = 147°
180° - 147° = 33°
∠1 is 33°
Finally, since that ∠4 is just an alternate interior angle of ∠1, ∠4 is 33°, too.

i need help whats the answer for 2x^2=50
Answer:
x = 5
x = -5
Step-by-step explanation:
2x^2 = 50
2x^2 - 50 = 0
2(x^2 - 25) = 0
2(x^2 + 5x - 5x - 25) = 0
2((x^2 + 5x) + (-5x - 25)) = 0
2(x(x + 5) - 5(x + 5)) = 0
2(x - 5)(x + 5) = 0
x - 5 = 0
x + 5 = 0
x = 5
x = -5
Solve f(x) = 2x + 2 what would f(x)=20
a. 20
b. 10
c. 9
d. 8
Answer:
the answer is c. 9
Step-by-step explanation:
20=2x+2
18=2x
x=9
Answer:
C
Step-by-step explanation:
Given f(x) = 2x + 2 and f(x) = 20, then equate right sides, that is
2x + 2 = 20 ( subtract 2 from both sides )
2x = 18 ( divide both sides by 2 )
x = 9 → C
