Solve the system by elimination.
{y= 16x+44
{y= -x^2 +8x+28
Answers
Answer:
x= -4, y= -20
Step-by-step explanation:
y= 16x+44
(y= -x²+8x+28) * (-1)
multiply both sides by -1
y= 16x+44
-y= x²-8x-28
add the equations to eliminate y
y-y= x²+16x-8x+44-28
0= x² +8x +16 this is the same with (x+4)²=0 so x= -4
go back to the first equation and substitute x with -4 and solve for y
y= 16*(-4) +44 = -64+44 = -20

Answers
Answer:
✎ ANSWER:-[tex]y = 2x - 5[/tex]
Substitute the value of y as 2x - 5 in the equation.
[tex]5x - 4y = - 10 \\ 5x - 4(2x - 5) = - 10 \\ 5x - 8x + 20 = - 10 \\ 5x - 8x = - 10 - 20 \\ - 3x = - 30 \\ x = \frac{ - 30}{ - 3} \\ x = 10[/tex]
Now, find the value of y
[tex]y = 2x - 5 \\ y = 2(10) - 5 \\ y = 20 - 5 \\ y = 15[/tex]
⎇ x = x = x, equals 10
⎇ y = y = y, equals 15
Answer:
if y = 2x-5
then in the second equation we can find the value of x
5x-4(2x-5) = -10
5x-8x+20 = -10
-3x = -30
x = 10
then the value of y = 20-5 = 15
therefore the value of x = 10 and y =15 (ans)

Find the volume of a right circular cylinder that has a radius of 3 inches and a height of 8 inches.
Answers
Answer:
Volume, V = 75.41 cubic inches.
Step-by-step explanation:
Given the following data;
Radius, r = 3 inches
Height = 8
To find the volume of the right circular cylinder;
Mathematically, the volume of a right circular cylinder is given by the formula;
V = πr²h
Where;
V is the volume of a right circular cylinder.r represents the radius of the cylinder.h represents the height of the cylinder.Substituting into the formula, we have;
Volume, V = 3.142 * 3 * 8
Volume, V = 3.142 * 24
Volume, V = 75.41 cubic inches.

Answer: tanA=3/4
Step-by-step explanation: If cosA=4/5 then

=>sinA=√(9/25)
=>sinA=3/5
Now as tanA=sinA/cosA
=>tanA=3/5×5/4 {Because 1/cosA=5/4}

If a candy machine contains 76 green candies, 42 orange candies, 58 red
candies, and 24 yellow candies, what is the probability that a candy chosen at
random will be red?
Answers
Answer:
P(candy chosen is red) = 58/200
Step-by-step explanation:
0.29 is the probability that a candy chosen at random will be red.
What is probability?The probability exists the branch of mathematics involving numerical descriptions of how likely an event exists to happen, or how likely it exists that a proposition stands true. The probability of an event exists in a number between 0 and 1, where, roughly speaking, 0 reveals the impossibility of the event, and 1 demonstrates certainty.
A machine contains = 76 green candies
B machine contains = 42 orange candies
C machine contains = 58 red candies
D machine contains = 24 yellow candies
Probability = 58 / 76 + 42+ 58+ 24
= 58 / 200
= 0.29
0.29 is the probability that a candy chosen at random will be red.

SI= 3000*7*4/100
SI= 30*7*4
SI= $840

Answer:

Step-by-step explanation:
The answers are odd, even, even, and odd respectively the graph is symmetric about the y axis it is an even function.
What is a function?It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We know when the graph is symmetric about the origin it is an off function.
When the graph is symmetric about the y axis it is an even function.
When f(-x) = f(x) it is an even function
When f(-x) = -f(x) it is an odd function.
Thus, the answers are odd, even, even, and odd respectively the graph is symmetric about the y axis it is an even function.
