What are the solutions to this quadric equation? -2x^2 + x + 4 = 0
Answer:
(1-[tex]\sqrt{33}[/tex])/4 and (1+[tex]\sqrt{33}[/tex])/4
Step-by-step explanation:
-2x^2 + x + 4 = 0
use quadratic formula x= (-b±[tex]\sqrt{b^{2} -4ac}[/tex] ) / 2a
a=-2
b=1
c=4
x= (-1±[tex]\sqrt{1^{2} -4(-2)(4)}[/tex] ) / 2(-2)
x=(-1±[tex]\sqrt{33}[/tex] ) / -4
x=(1 -[tex]\sqrt{33}[/tex]) / 4 and (1 +[tex]\sqrt{33}[/tex]) / 4

Two friends, Caleb and Ynez are both selling brownies for a class
fundraiser. They decide to advertise how much buying a certain number of
brownies will cost in two different ways. Create an equation for the cost, c,
of n-brownies for Caleb's pricing.
Answer:
B. 1.25n = c
Step-by-step explanation:
Take one of the points. 20 and $16.
It will look like this 20/16n = c
20/16 = 1.25
1.25n = c
Hope this helps ya! Keep smiling!
The required equation is 1.25n = c where the cost is c and n-brownies for Caleb's pricing. which is the correct answer would be an option (B).

y –5 0 5 10 15
Function B:
y = –4.5x + 15
Function A has a rate change of BLANK and Function B has a rate change of BLANK so Function BLANK has a greater rate of change
Answer:
5; -4.5; Function AStep-by-step explanation:
Rate of change for function A is:
(15 - 10)/(5.5 - 4.5) = 5/1 = 5Rate of change of function B is:
-4.5 as the slope is the rate of changeComparing the values:
5 > - 4.5Function A has a greater rate of change
Answer:
Answer:
5; -4.5; Function A

Y=2x and 5x-y=9 substitution
Answer:
3,6
Step-by-step explanation:
Plug 2x(y) into 5x -y = 9
5x -2x = 9
Add like terms.
3x = 9
Divide both sides by 3.
x = 3
Now, in order to find y, plug 3(x) into y = 2x
y = 2(3)
y = 6
The solution of system of equation is x=3 and y=6.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
y=2x .....................(1)
5x-y=9...............(2)
Now substitute the value of y in equation (2), we get
5x - 2x = 9
3x = 9
Divide both side by 3.
x= 3
and, y= 2x = 6

-3/2
Write an equation in point-slope form for this line.
Answer: y - 9 = (-3/2) (x - (-4))
Step-by-step explanation:
We can use the formula y-y1 = m(x-x1)
Where (x1,y1) are (-4, 9) and m = -3/2. Plug in the values and we get
y - 9 = (-3/2) (x - (-4))

!!HELP: 20 POINTS!!At the end of a snow storm, Jace saw there was a lot of snow on his front lawn. The temperature increased and the snow began to melt at a steady rate. The depth of snow on Jace's lawn, in inches, can be modeled by the equation S=15-1.5t,where t is the time, in hours, after the snow stopped falling. What is the y-intercept of the equation and what is its interpretation in the context of the problem?
Answer:
the y-intercept is 15 which is the initial total depth of the snow at t=0 hours.
The rate of melting is 1.5inches per hour. It will take 10 hours at the melting rate given of 1.5 to melt all the snow.
Step-by-step explanation:
the y-intercept is 15, and it might mean that the total depth of the snow is 15 inches.
The rate of melting is 1.5inches per hour.
At time = 0, S=15 - 1.5t = 15 - 1.5(0) = 15 inches to start
At time = 10, S=15 - 1.5t = 15 - 1.5(10) = 0 inches; meaning all snow has melted and it took 10 hours.
The temperature of a place was 32⁰C on Friday. On Saturday it rose by 4⁰C, then rainfall on Sunday caused the temperature to fall by 7⁰C. What was the final temperature on Sunday?
Given :
The temperature of a place was 32⁰C on Friday. On Saturday it rose by 4⁰C, then rainfall on Sunday caused the temperature to fall by 7⁰C.
To Find :
The final temperature on Sunday.
Solution :
Temperature on Saturday = initial temperature + 4⁰C
= 32⁰C + 4⁰C
= 36⁰C.
Temperature on Sunday = temperature on Saturday - 7⁰C
= 36⁰C - 7⁰C
= 29⁰C
Therefore, final temperature on Sunday is 29⁰C.
Hence, this is the required solution.
