Please help me solve these are quadratic equations: I
Answer:
[tex]\boxed {\boxed {\sf a= 3, b=7, c=2}}[/tex]
[tex]\boxed {\boxed {\sf Y-intercept = c }}[/tex]
[tex]\boxed {\boxed {\sf Minimum}}[/tex]
Step-by-step explanation:
a. a, b, c
Quadratic equations in standard form are written as:
[tex]f(x)= ax^2+bx+c[/tex]
The exponents are listed from greatest to least. The quadratic is already in this form, so match up the variables and values in the equation.
[tex]f(x)= 3x^2+7x+2[/tex]
[tex]a=3 \\b=7 \\c=2[/tex]
b. Y-intercept
The y-intercept for a quadratic is c.
You can also substitute 0 in for x, because the y-intercept occurs when the quadratic crosses the y-axis (at x=0).
[tex]f(0)= 3(0)^2+7(0)+2[/tex]
[tex]f(0)=3(0)+7(0)+2\\f(0)= 0+0+2\\f(0)=2[/tex]
We know that c=2, so the y-intercept is c.
c. Maximum/minimum
The entire quadratic is positive, so the quadratic opens up and has a minimum.

Which function has zeros at x = -2 and x = 5?
Оооо
f(x) = х2 + 2x – 10
f(x) = х2 - 2x – 10
f(x) = х2 + 3х – 10
f(x) = х2 – 3х – 10
6y = 12x + 36
15y = 45x + 60
The system has no solution
The system has exactly one solution
The system has infinitely many solutions
Equation 1: 6y = 12x + 36
Equation 2: 15y = 45x + 60
Solve equation 1 for y by dividing both sides by 6 to get: y = 2x + 6
Replace y in equation 2:
15(2x + 6) = 45x + 60
Simplify:
30x + 90 = 45x + 60
Subtract 45x from both sides:
-15x + 80 = 60
Subtract 90 from both sides
-15x = -30
Divide both sides by -15:
X = 2
Now replace x in the first equation and solve for y:
6y = 12(2) + 36
6y = 24 + 36
6y = 60
Divide both sides by 6
Y = 10
The solution is x = 2, y = 10
The answer is there is only one solution.

concert tickets are sold for $ 8 for the stalls and $ 6 for the gallery. For a function, 400 seats were sold for a total of $ 2,888. How many seats of each type were sold?
Answer:
156 seats were sold at the store and 244 at the gallery
Step-by-step explanation:
Let the amount of stalls be x
Let the price per ticket for gallery be y
If 400 seats were sold in total, then;
x+y = 400 ... 1
If concert tickets are sold for $ 8 for the stalls and $ 6 for the gallery with a total of $2888, then;
8x + 6y = 2888 ....2
Solve both equation simultaneously
x+y = 400 ... 1 * 8
8x + 6y = 2888 ....2 .*1
__________
8x+8y = 3200 .
8x + 6y = 2888
Subtract
__________
8y - 6y = 3200 - 2888
2y = 312
y = 312/2
y = 156
Since x = 400 - x
y = 400 - 156
y = 244
hence 156 seats were sold at the store and 244 at the gallery
What’s the answers for these questions and how do you solve it?
What is the slope of a line containing the ordered pairs (2, 3) and (-4, 0)?
Answer:
1/2
Step-by-step explanation:
x change: 2 --> -4 = -6
y change: 3 --> 0 = -3
y/x = -3/-6 = -1/-2 = 1/2
Answer:
1/2
Step-by-step explanation:
(y2-y1)/(x2-x1) is the formula for slope
(0-3)/(-4-2) = 1/2
