Answer:
[tex]s(u(2)) = 135[/tex]
Step-by-step explanation:
[tex]u(t) = 7t - 2 \\ u(2) = 7(2) - 2 \\ u(2) = 14 - 2 \\ u(2) = 12 \\ \\ s(t) = {t}^{2} - 9 \\ s(u(2)) = {(12)}^{2} - 9 \\ s(u(2)) = 144 - 9 \\ \\ s(u(2)) = 135[/tex]
I hope I helped you^_^
For the functions u(t) = 7t - 2 and s(t) = t² - 9. s(u(2)) = 135
What is a function?A function is a mathematical equation that shows the relationship between two variables.
For the functions u(t) = 7t - 2 and s(t) = t² - 9.To find what is s(u(2)), we proceed as follows.
Since u(t) = 7t - 2. Then u(2) is evaluated when t = 2. So, we have that
u(t) = 7t - 2
u(2) = 7(2) - 2
u(2) = 14 - 2
u(2) = 12
Now, since u(2) = 12 and s(t) = t² - 9
s(u(2)) is evaluated as follows
s(t) = t² - 9
s(u(2)) = 12² - 9
s(u(2)) = 144 - 9
s(u(2)) = 135
So, s(u(2)) = 135

Which equation shows a proportional relationship between x and y?
A. y = 9
B. y = 3x + 1
C. y = −3x − 2
D. y = 4x
NO LINKS
B. y=3x+1
Step-by-step explanation:
#Hopeee Itttt Helppsssssss!
A proportion relationship is a direct relationship between two variables thus y = 4x will be the proportional relationship between x and y thus option (D) will be correct.
What are the ratio and proportion?The ratio is the division of the two numbers.
Proportion is the relation of a variable with another. It could be direct or inverse.
A proportional relationship is given as,
A ∝ B
Removing proportionality
A = kB
Here, k is the constant of proportionality.
As per the given in last option,
y = 4x
x = (1/4)y
Removing constant.
x ∝ y
Hence "A proportion relationship is a direct relationship between two variables thus y = 4x will be the proportional relationship between x and y".

is -5 a rational or an irrational number
Answer:
Rational
Step-by-step explanation:
An irrational number cannot be written as the ratio. of two integers. An irrational number is simply the opposite of a rational number. (Recall that a rational number is one that can be represented as the ratio of two integers.
A rational number is one that can be written as an integer over an integer, with non-zero denominator. ie. all your fractions.
An irrational number cannot be expressed as a ratio of integers
-5 is rational because it is a number that ends and is not a decimal that doesnt terminate.

Tom makes $249.25 in 5 days. How much does he make in 4 days?
Answer:
$199.4 in four days
$49.85 in one day
Step-by-step explanation:
249.25 / 5 =49.85
49.85 x 4 = 199.4
Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The amount that Tom makes in 4 days is $199.4.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that Tom makes $249.25 in 5 days. Therefore, the amount that Tom makes in a day is,
Amount Tom makes in a day = $249.25 / 5 days
= $49.85 per day
The amount of money that Tom can make in 4 days is,
Amount = $49.85 per day × 4 days
= $199.4
Hence, the amount that Tom makes in 4 days is $199.4.

There's a big soccer game next month, and Juan has purchased 3 tickets for himself and his siblings. He spent 53 dollars.
Rosie wants to take her family also, but knows her parents and some cousins will want to attend as well. She knows she will have to purchase 9 tickets. Estimate approximately how much money Rosie will likely have to spend on the tickets. Explain your reasoning below.
Answer:
53 divided by 3 would be $17.66
so 17.66 times 9 would be $158.94
Answer:
158.4 dollars
Step-by-step explanation:
so first of all the three tickets were 53 dollars so we divide the dollars and the no of tickets like this 53÷3 = 17.6 dollars
so since each ticket is 17.6 dollars now we know that Rosie wants to purchase 9 tickets so we will multiply the no of tickets by dollars per ticket like this
9×17.6= 158.4 dollars
and 158.4 is your answer
Harita must memorize 90 measures of music for her cello solo at a concert. She plans on memorizing 18 new measures for every 3 days of practice. Which equation can be used to determine m, the number of measures Harita still needs to memorize, as a function of d, the number of days of practice since she began learning the piece?
m = 72 – 15d
m = 90 – 6d
m = 101 – 21d
m = 108 – 3d
Answer:
m = -90 - 6d
Step-by-step explanation:
18 ÷ 3 = 6 { She needs to memorize six measures a day. }
m = 90 - 6d { She has memorized bd measures }

Step-by-step explanation:
DAC = 99

B is inside DAC, and so is DAB. So CAB must add to 59 to get to 99, nothing over that because it's inside DAC.
So 99 - 59 = 40
CAB must be 40°

Twice a quantity usually indicates to take two of the things in question; usually this indicates to multiply by 2. Thus "twice a number x" can be written symbolically as 2x. If this is part of a problem, say twice a number x is 6, then we can rewrite algebraically as 2x=6; dividing both sides by 2 yields x=3.
How many solutions exist for the given equation?
3(x – 2) = 22 – x
3(x - 2) = 22 - x
3x - 6 = 22 - x
3x + x = 22 + 6
4x = 28 / : 4
x = 7

you and your friend went shopping. you bought 3 shirts and 4 sweaters for $69. your friend bought 6 shirts and 2 sweaters for $66 how much does one shirt and one sweater coat each
I need this answered quickly
Answer:
Shirt = $7
Sweatshirt = $12
Step-by-step explanation:
Let T represent shirts and S to represent sweatshirts
you bought 3T + 4S = 69
your friend bought 6T + 2S = 66 multiply second equation by -2
-2 x 6T + 2S = 66
-12T - 4S = -132 now find the sum of this and first equation
3T + 4S -12T - 4S = 69 - 132 add like terms
-9T = -63 divide both sides by -9
T = 7 this is the cost of one shirt to find the cost of a sweatshirt we replace the T in any equation with 7
3T + 4S = 69
3*7 + 4S = 69
21 + 4S = 69 subtract 21 from both sides
4S = 48 divide both sides by 4
S = 12
