Answer:
The equations are;
a -b + c = 5
c = -4
16a + 4b + c = 0
Step-by-step explanation:
Generally, the equation of a quadratic formula can be written as;
y = ax^2 + bc + c
From the graph, we have three points and we want to form equations from these points
These points are;
(-1,5) (0,-4) and (4,0)
To get the equation from each point, we make a substitution for both x and y
For the first;
5 = a(-1)^2 + b(-1) + c
5 = a-b + c
For the second;
-4 = a(0)^2 + b(0) + c
c = -4
For the third;
0 = a(4)^2 + b(4) + c
0 = 16a + 4b + c

What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The linear equation is given below.
y = 2x - 1/2
At x = 0, the value of the variable 'y' will be given as,
y = 2(0) - 1/2
y = - 1/2
At y = 0, the value of the variable 'x' will be given as,
0 = 2x - 1/2
2x = 1/2
x = 1/4
The x-intercept and y-intercept of the line are at (0, -1/2) and (1/4, 0). Then the correct option is C.

O 38.30 foot-pounds
O 574.53 foot-pounds
O 750.00 foot-pounds
Answers
Answer:
C) 574.53 foot-pounds
Step-by-step explanation:
got it right on edge :)
Awagon is being pulled by a force of 15 pounds. the required work done is 574.53 to pull the wagon So, Option C) is correct work done = 574.53.
What is work done?The work done is product of force and cosine of displacement.
Given; Awagon is being pulled by a force of 15 pounds. We need to find How much work is done in moving the wagon 50 feet if the handle makes an angle of 40° with the ground.
Force = 15 pounds
distance = 50 feet
Ф = 40°
We can calculate the work done as;
work done = force x displacement x cosФ
work done = 15 x 50 x cos40
work done = 15 x 50 x 0.76
work done = 574.53
Therefore, the required work done is 574.53 to pull the wagon.

Kenise will begin college as a freshman next fall and has received a 10-year $5,500 Federal Direct Unsubsidized Loan with an interest rate of 6.8%. She will be required to begin making payments six months after graduation. How much interest will accrue while she is still in school and over the six-month grace period?
Answers
Answer:
The interest accumulated will be $3,927
Step-by-step explanation:
Mathematically;
Simple interest = PRT/100
From the question, we have P as the amount borrowed = $5,500
R is the interest rate = 6.8%
T is the time which is 10 years + 6 months = 10 1/2 years
The interest accrued will thus be;
(5,500 * 6.8 * 10.5)/100 = $3,927

Step-by-step explanation:
[tex]3(5x+2)=-5(3x-5)+3x\\15x+6=-15x+25+3x\\15x+6=-12x+25\\27x=19\\x= 19/27[/tex]
Hope this helps plz hit the crown :D
[tex]3(5x+2)=-5(3x-5)+3x[/tex]
Distribute 3 in 5x+2 and -5 in 3x-5
[tex]15x+6=-15x+25+3x[/tex]
Multiplying 2 negatives will be positive (Same goes to dividing 2 negatives.)
[tex]15x+15x-3x=25-6[/tex]
Move the x term to the same side and constant term to the same side.
(Whenever you move to another side, change the sign/operator to opposite. From plus to minus and from multiply to divide.)
[tex]27x=19\\x=\frac{19}{27}[/tex]
Thus, the answer is 19/27
In ∆ABC, ∠A is a right angle, and ∠B measures less than 40°. Which of the following phrases best describes the measure of ∠C?
Answers
The phrase that describes the measure of ∠C is greater than 50°.
What is a right triangle?A right triangle is a triangle that has one of its angle as 90 degrees.
The triangle is named as ABC.
∆ABC
where
∠A = 90 degrees
∠B < 40 degrees
The sum angles in a triangle is 180 degrees.
Therefore,
let x be the third angle
Hence,
∠A + ∠B + ∠C = 180°
∠B + ∠C = 180 - 90
∠B + ∠C = 90°
∠B < 40 degrees
Therefore,
∠C > 50 degrees.
