This is impossible to solve.
Step-by-step explanation:For an equation or inequality to be solvable, there must be the same number of inequalities as variables. Here, there is an x and there is a y. This means that you need at least two inequalities to solve it.
You can, however, rearrange to get x or y on one side.
This can be done for x:
5x < 10 + 2y
x < 2 + 2/5y
Or it can be done for y:
5x < 10 + 2y
5x - 10 < 2y
2.5x - 5 < y
A rocket is launched from a tower. The height of the rocket, y in feet, is related to the
time after launch, x in seconds, by the given equation. Using this equation, find the
time that the rocket will hit the ground, to the nearest 100th of second.
y = –16x2 + 119x + 57
Answer:
7.89 seconds
Step-by-step explanation:
using the quadratic formula (-b+-√(b^2-4ac))/2a
a=-16 b=119 c=57
x=-0.451
and
x=7.889
time cant be negative so use the positive x
Time required for the rocket to hit the ground would be 7.9 s.
What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
We are given the quadratic equation as;
-16x² + 119x + 57 = 0
By using the quadratic formula,
x = [-b ± √b² - 4ac]/2a
Here, a = -16, b = 119 and c = 57
b² - 4ac = (119 )² - 4(-16)(57)
= 14161 + 3648
= 17809
So, x = [-(119) ± √17809]/ 16(2)
= (-119 ± 133.4)/32
Therefore, the time is 7.9 s.

Find the perimeter of a rectangle whose length is 12 longer than its width
with an area of 45 square feet. To earn 5 points write the mathematical
sentence, the value of Length, width and perimeter
Answer:
l = 21
w = 9
P = 60
Step-by-step explanation:
l = 12 + w
A = l*w = 45
substitute l = 12 +w
45 = (12 + w) * w
45 = 12w + w^2
w^2 + 12w - 45 = 0
w^2 + 2*6*w +36 = 45 + 36 (added 36 on both sides 6^2)
(w + 6) ^2 = 45+36 = 81
w + 6 = +-9
As width cannot be negative w = 9
so l = 12 + 9
= 21
Perimeter = P = 2 (l + b)
= 2 ( 21 + 9)
= 2 (30)
= 60

line w passes through point (-6,-7) and has a slope 1/2. what is the equation for the line in point-slope form?
Answer:
y + 7 = [tex]\frac{1}{2}[/tex] (x + 6)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
Here m = [tex]\frac{1}{2}[/tex] and (a, b ) = (- 6, - 7 ) , then
y - (- 7) = [tex]\frac{1}{2}[/tex] (x - (- 6) ) , that is
y + 7 = [tex]\frac{1}{2}[/tex] (x + 6)

the marked price of a calculator is 1800 the shopkeeper allows 10%discount and still makes 8%profit at what price did the shopkeeper purchase the calculator
Answer:
multiple 1800 by 10%
1800 ×10%180subtract the selling price from the discount given.1800 -180Ans: 1,620
multiple 1800 by 8%
1800 × 8%1,656subtract the selling price from the discount given.1800 - 1,656Ans: 144
subtract the discount of 10% from 8%
1620 -144
Ans:1,476
so therefore the price for the calculator is 1476.

Evaluate the expression.
2−[(2+10(−1)÷2)+1]
What is the value of the expression?
4
Step-by-step explanation:Review
To evaluate the expression, lets use BODMAS. Before we get to the solving part, lets revise BODMAS.
=> B in BODMAS is brackets. This means that whatever operations are inside a bracket, we must solve that first.
=> O in BODMAS is Orders. The O is used very rarely, there is a possibility that there is no powers, exponents.
=> D in BODMAS is Division. This means that whatever division is occurring in the expression must be done first (Unless if there is a bracket).
=> M in BODMAS is Multiplication. This means that whatever multiplication is occurring in the expression must be done next.
=> A in BODMAS is Addition. This means that whatever addition is occurring in the expression must be done then.
=> S in BODMAS is Subtraction. This means that whatever subtraction is occurring in the expression must be done last.
Solution:Now, lets get to the point. We need to find the expression '2−[(2+10(−1)÷2)+1]'. Using the help of BODMAS, we can solve it.
Step 1: Simplify the innermost bracket.
2 − [( 2 + 10(−1)÷2)+1]
=> 2-[(2-10÷2)+1]
Note: Since in the innermost bracket there is no operation, we can open the innermost bracket and get along with the second inner bracket.
Step 2: Simplify the second inner bracket.
=> 2 - [(2 - 10 ÷ 2) + 1]
=> 2 - [(2 - 5) + 1]
=> 2 - [(-3) + 1]
=> 2 - [-3 + 1]
Step 3: Simplify the third inner bracket.
=> 2 - [-3 + 1]
=> 2 + 2
Step 4: Solve.
=> 2 + 2
=> 4
Final Answer.
Therefore, 4 is our answer after working on this problem.
Answer:
4
Step-by-step explanation:the answer is 4 because you have to 20 2-2+10 and that is ten. then minus one is 9 then 9/2=3 and then 3+1 equals 4
1- 3.1 = what - 1.5
2- 6.4 = what + 2.6
other questions
3- x − 8 = -3
4- -7 = what - 7
5- -15 = what + 13
6- what - 10 = - 1
7- -1 - what = -8
8- -25 + x = -8
9- -14 + what = 10
10- -30 − what = -25
11- what − 20 = -6

Leah is writing an equivalent equation which solves for y. What should be her next step?
3 x + 4 y = 8. 3 x minus 3 x + 4 y = 8 minus 3 x. 4 y = 8 minus 3 x.
Add 4y to both sides of the equation.
Subtract 4y from both sides of the equation.
Multiply both sides of the equation by 4.
Divide both sides of the equation by 4
Answer:
y= 2

Determine if the ordered pairs (1. - 2) and (-4,2) are solutions of the following linear inequality in two variables.
-X<-y
.
Is the ordered pair (1. - 2) a solution of the linear inequality?
Is the ordered pair (-4,2) a solution of the linear inequality?
Answer:
First is, second is not.
Step-by-step explanation:
Start plugging them!
[tex]-(1) < -(-2) \rightarrow -1 < 2 \\ \\- (-4) < -(2) \rightarrow 4 < -2[/tex]
First one is true, so the pair is a solution.
Second is false, (4 is obviously bigger!) so it's not a solution.
If you end up having to check multiple values, your best bet is to draw the solutions on a convenient plane and see where the points lay
Triangle R S T is shown. Angle R S T is a right angle. The length of R S is 10, the length of R T is 26, and the length of S T is 24. Use the diagram and side lengths of triangle RST to determine the angles used for the trigonometric ratios. sin( ) = Twelve-thirteenths tan( ) = Five-twelfths
Answer:
sin(R) = 12/13tan(T) = 5/12Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relationship between sides of a right triangle and trig functions of the acute angles. It tells you ...
Sin = Opposite/Hypotenuse
sin(R) = 24/26 = 12/13
and ...
Tan = Opposite/Adjacent
tan(T) = 10/24 = 5/12
Answer: SIN = R and TAN = T

B.(- 1, 1)
C.(5, - 7)
D.(- 5, 7)
Answer: D, (- 5, 7)
Step-by-step explanation:
Since the transformation is - 2, + 3 we just need to subtract 2 from the x value and add 3 to the y value.
- 3 - 2 = - 5
4 + 3 = 7
