What are the solutions to the system of equations? y=2x^2−6x+3 y=2x+3
Answer:
Step-by-step explanation:
y=2x²-6x+3
y=2x+3
2x²-6x+3=2x+3
2x²-6x+3-2x-3=0
2x²-8x=0
2x(x-4)=0
x=0,4
y=0+3=3
and y=2(4)+3=11
so solutions are (0,3) and (4,11)

Answer:
Down below
Step-by-step explanation:
The graph is attached to the answer.
What is function?The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.
Given is a function,
g(x) = -3, -8≤x-2
1, -2≤x≤4
5, 4≤x≤10
The function g(x) is a discrete function. It is continuous between -8 to -2, -2 to 4, and 4 to 10.
And the open circle at -8, -2, 4, and 10.

Sorry I don’t understand the second one
Step-by-step explanation:
HELP ME PLEASE!!!!!!
I just wanna make sure i’m doing this right
Answer:
175%
Step-by-step explanation:
The first one is a whole=1
the second one is cut in four but only 3 are shaded so 1/4=0.25 0.25*3=0.75
3/4/0.75 is shaded
so 1+0.75=1.75
1.75=175%
What are the values of x and y if you answer is not a whole number write it as a decimal and round if neccasasry
a) 3x + 5y = 26
b) 2x + 2y = 12
First, we need to find a way to equate either the x terms or the y terms in each equation. a) 6x + 10y = 52
b) 6x + 6y = 36
Then take equation b) from the equation a) to eliminate the x component.
a) 6x + 10y = 52
- b) 6x + 6y = 36
0x + 4y = 16
y = 4 ?
Then substitute the value of y into either equation to find the value of x.
b) 2x + 2y = 12
2x + (2x4) =12
2x + 8 = 12
2x = 4
x = 2

Using the equation y=kx what would be the proportionate equation if she worked 25 hours and made 150.00
Answer:
y = 6x
Step-by-step explanation:
Equation representing the relation between duration of work and earning is,
y = kx
Here, y = earnings
x = Working hours
k = Proportionality constant
By substituting the values in the given equation,
x = 25 hours
y = $150
150 = k(25)
k = 6
Therefore, equation modeling the situation will be,
y = 6x
This table shows a proportional relationship between the grams of peanuts and raisins in a bag of trail mix. Enter the number of grams of peanuts in a bag for every 1 gram of raisins
Answer:
3.5
Step-by-step explanation:
Hope this helps!
There are 3.5 gram of peanuts in a bag for every 1 gram of raisin
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
From the table:
14 g of peanut = 4 gram of raisins
Hence:
1 gram of raisin = (14/4) = 3.5 gram of peanuts
There are 3.5 gram of peanuts in a bag for every 1 gram of raisin

The two legs of a right triangle measure 7 inches and 5 inches. Find the measure of the acute angle that is included between the longer leg and the hypotenuse. WILL GIVE BRAINIEST TO FIRST RIGHT ANSWER
Answer:
44.4 degrees
Step-by-step explanation:
Given the following
Hypotenuse = 7
Longer leg = 5 (adjacent])
Let the acute angle angle between both sides be x
According to SOH CAH TOA
Cos theta = adj/hyp
Cos x = 5/7
x= arccos (5/7)
x = arccos (0.7143)
x = 44.4degrees
Hence he measure of the acute angle that is included between the longer leg and the hypotenuse is 44.4 degrees
A helicopter flies 665 feet above ground. What is the measure of the angle of depression fro t the helicopter to the girls line of sight
Answer:
67°
Step-by-step explanation:
CHECK THE ATTACHMENT FOR THE FIQURE
From, trigonometry
tan(θ) = opposite/ adjacent
✓The helicopter is 665 feet from ground.
✓Distance of the helicopter and the line of sight of the girl will be the OPPOSITE SIDE, which is
(665ft - 5 ft)
= 600 ft
✓ from the figure, we can see the distance on the Horizontal side which is the ADJACENT SIDE as ( 280 ft)
✓angle of depression can be calculated as
tan(θ) = opposite/ adjacent
tan(θ)= (660/280)
tan(θ)= 2.357
tan-1=(2.357)
θ= 67°
Hence, angle of depression is 67°
From a distance of 1217 feet from a spotlight,the angle of elevation to a cloud base is 43 degrees. Find the height of the cloud base to the cloud base to the nearest foot
Answer:
1134.9 ft
Step-by-step explanation:
CHECK THE ATTACHMENT FOR THE FIQURE
From, trigonometry,
Tan(X) = opposite/ adjacent
Distance from the spotlight = 1217 ft, which is the adjacent sides
Let the height of the cloud= X
, Which is the opposite sides
Then substitute, we have
Tan(43°)= X/1217
(0.9325)= X/1217
X= 0.9325×1217
= 1134.9 ft
Hence, the height of the cloud base to the cloud base to the nearest foot is 1134.9 ft
Stacy made 3 of her car payments late and was fined 3 late fees. The total change to her savings from late fees was - $24. How much was each late fee?
Answer:
$8
Step-by-step explanation:
I got my answer of $8 because I knew that the total amount of money she was charged for late fees was $24, and she was charged for 3 late fees. Then, I did $24 divided by 3 late fees and got $8 per late fee as my answer.
24 divided by 3 equals 8.
