Step-by-step explanation:
First you have to get x by itself. So you do 90-90= 0 and 30-90= -60 which gets:
90 - 3/2x < 30 to -3/2x < -60
Then, you do -3/2 - (-3/2)= 0 and do the same to -60. -60 - (-3/2) = -58.5
which makes it look like
X = -58.5
-58.5 is a smaller number than -40 which means, when you fill it in for x it works
-58.5 ≤ -40

Write the equation of the line fully simplified slope-intercept form.
Answer:
Step-by-step explanation:
y = mx + b <-- slope intercept form
Looking at the line from point (0,-5) to (3,0)
The slope (mx), rise over run
Rises 5 (in the positive direction, up) and runs 3 (in the positive direction, right)
the slope being 5/3
Then the b being your y-intercept
-5 will be your b because the line crosses the y axis at (0,-5) but the y-intercept is -5
Overall: y = [tex]\frac{5}{3}[/tex] x + (-5)
or
y = 5/3 x - 5
Another car dealership sells a truck for the wholesale price of $12,000. During a special sales event, the dealership offers a 10% discount off of the price. After the discount, how much will a customer pay for this vehicle? Show your work.
Answer:
$10,800
Step-by-step explanation:
Given that:
Wholesale price of the truck = $12,000
At the special sales event, the discount offered on the price = 10% of the wholesale price
Therefore the discount can be calculated as follows:
10% of Wholesale price
Wholesale price is given as $12,000.
[tex]\Rightarrow \dfrac{10}{100} \times 12000\\\Rightarrow \bold{\$1200}[/tex]
Now, we have to find the price to be paid by customer after the discount being offered due to the special sales event.
Discounted price = Wholesale price - Discounted offered due to special sales event.
Discounted price = $12000 - $1200 = $10,800
Therefore, the answer is:
$10,800

What are the factors of -24 that have a sum of 5?
Answer:
Step-by-step explanation:
5 Easy as 1-2-3
5 is a prime number.
Prime factorization: 5 is prime.
The exponent of prime number 5 is 1. Adding 1 to that exponent we get (1 + 1) = 2. Therefore 5 has exactly 2 factors.
Factors of 5: 1, 5.
Factor pairs: 5 = 1 x 5.
5 has no square factors that allow its square root to be simplified. √5 ≈ 2.236.

Triangle ABC is an obtuse triangle with the obtuse angle at vertex B. Angle A must be
less than 90°.
greater than 90°.
congruent to angle B.
congruent to angle C
Answer:
"less than 90°."
Step-by-step explanation:
This is because an obtuse triangle can be defined as "An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles." Therefore, there can only be ONE obtuse angle. Therefore, with the obtuse angle being at vertex B, there cannot be another one at vertex A.

Grant has $58 in a savings account. He plans on depositing $30 into the
account each month and not taking any money out of the account. Which
function rule will give the total amount T that he has in the account
after n months?
Answer
I believe it is the first answer
Step-by-step explanation:
You would have to multiply 30 by however many months he deposits money to find how much he has in he account at that time
Hope this helps
The function rule of the total amount T in the account after n months is
T = 30n + 58.
Option A is the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Amount in the account = $58
Amount deposited each month = $30
The total amount after n months.
T = 58 + 30n
Thus,
The T = 30n + 58 is the total amount in the account after n months.

A toy rocket is launched vertically upward from a 8 foot platform with an
initial velocity of 120 feet per second. Its height h at time t seconds after
launch is given by the equation h(t) = -16t^2 + 120t + 8. How many seconds
until the rocket is 40 feet? (There may be more than one answer)
A) 0.28
B) 0.94
C) 3.17
D) 4.62
E) 5.98
F) 6.44
G) 7.22
H) 8.17
Answer:
We get t= 7.22 and t=0.28
The correct options are Option A and Option G
Step-by-step explanation:
The height h of toy rocket at time t seconds after launch is given by the equation [tex]h(t) = -16t^2 + 120t + 8[/tex]
We need to find how many seconds until the rocket is 40 feet?
We are given height of rocket h(t) = 40 feet
and we need to find time t
Using the equation [tex]h(t) = -16t^2 + 120t + 8[/tex] we can find time t
We have h(t)=40
[tex]h(t) = -16t^2 + 120t + 8\\Put\:h(t)=40\\40= -16t^2 + 120t + 8\\16t^2-120t-8+40=0\\16t^2-120t+32=0[/tex]
Now, we will solve the quadratic equation using quadratic formula: [tex]t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
We have a =16, b=-120 and c=32
Putting values and finding t
[tex]t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\t=\frac{-(-120)\pm\sqrt{(-120)^2-4(16)(32)}}{2(16)}\\t=\frac{120\pm\sqrt{14400-2048}}{32}\\t=\frac{120\pm\sqrt{12352}}{32}\\t=\frac{120\pm111.12}{32}\\t=\frac{120+111.12}{32}, t=\frac{120-111.12}{32}\\t=7.22\:,\:t=0.28[/tex]
So, we get t= 7.22 and t=0.28
The correct options are Option A and Option G
1. If RU = 16, UT = 20, and SR = 16, what is the perimeter of SUT?
Figure:
Please answer ASAP!
Answer:
72
Step-by-step explanation:
If SR and RU have the same length, a right angle, and a shared side, we know that they are congruent triangles using SAS (Side Angle Side). Our equation to find the perimeter would be SR + RU + UT + TS or 16 + 16 + 20 + 20(using our knowledge of the congruent triangles) = 72.
The Perimeter of SUT is 72 units.
What is Pythagoras theorem?According to the Pythagoras theorem, the square of the hypotenuse of a triangle, which has a straight angle of 90 degrees, equals the sum of the squares of the other two sides.
Given:
RU = 16, UT = 20, and SR = 16
Now, Using Pythagoras theorem
UT² = RT² + RU²
20²= RT² + 16²
RT² = 400- 256
RT² = 144
RT= 12
And, ST=20
Now, Perimeter of SUT
= 16 + 16 + 20 +20
= 72

What is the x-coordinate of this endpoint?
Anyone got an answer
also it doesn't gimme the option of making this 5pts :(
Answer:
Step-by-step explanation:
Each of the squares has trinomials that factor. x^2 - 14x + 49 = (x - 7)^2
When you take the square root (to get the side length) you get x - 7. So the length of each square is x - 7) = 0;..........x=7 That's the answer to a.
The answer to b is the same. The width =7
It's a square both sides have to be equal.
The length of the rectangle when the two squares are put together is 7 +7 = 14.
Answer: Question a = 7..... Question b = 7 ......... Question C = 14

Rewrite the sum of 75+18 as a product of a number and another sum
Answer:
(2)(9) + 75 = 75+18
Step-by-step explanation:
(2)(9) + 75 = 75+18
The expression written as a product of a number and another sum is 3(25 + 8)
Given the expression 75 + 18, we are to write as a product of a number and another sum.
First we need to find the GCF of 75 and 18
75 = 3 * 25
18 = 3 * 6
Since 3 is common to both D+GCF, we can factor it out from the expression to have:
75 + 18 = 3(25 + 8)
Hence the expression written as a product of a number and another sum is 3(25 + 8)

The product of the roots of 2x^2 - 7x + N = 0 is -5. Find N.
Let a and b be the roots of 2x² - 7x + N. Then
2x² - 7x + N = 2 (x - a) (x - b)
2x² - 7x + N = 2x² - 2 (a + b) x + 2ab
so that
2 (a + b) = 7
2ab = N
The product of the roots is ab = -5, so
N = 2 • (-5) = -10
