PLEASE HELP, THIS IS MY LAST QUESTION FOR THE YEAR SO I CAN PASS ALGEBRA (BRAINLIEST IF ANSWERED WITHIN 30 MINS AND CORRECT)
An expression is shown below:
f(x) = 2x2 − 3x − 5
Part A: What are the x-intercepts of the graph of f(x)? Show your work. (2 points)
Part B: Is the vertex of the graph of f(x) going to be a maximum or minimum? What are the coordinates of the vertex? Justify your answers and show your work. (3 points)
Part C: What are the steps you would use to graph f(x)? Justify that you can use the answers obtained in Part A and Part B to draw the graph. (5 points)
Answers
Answer:
x intercepts: (-1,0) and (2.5,0)
It will be a minimum because the coeficcent for the degree is positive. The coordinates of the vertex are: (.75,-6.125)
To graph this I would first draw points on the vertex (.75,-6.125) and the x intercepts (-1,0) and (2.5,0). I would then simply just sketch a parabola that met all those points.

The difference is that (-3)^4 has a negative 3 with parenthesis around it, which means that if it was in PEMDAS, you would work that out first.

Find the gradient of the line segment between the points (-4,4) and (0,12).
Answers
Answer:
2
Step-by-step explanation:
the gradient = (12-4)/(0+4)=8/4=2
Answer:
gradient = 2
Step-by-step explanation:
Calculate the gradient m using the gradient formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 4, 4) and (x₂, y₂ ) = (0, 12)
m = [tex]\frac{12-4}{0+4}[/tex] = [tex]\frac{8}{4}[/tex] = 2
If 8 cents are needed to buy 10 pebbles, how many dollars are needed to buy 205 pebbles?
Answers
Answer:
Hello There!!
Step-by-step explanation:
If 8 cents=10 pebbles then do 205 divided by 10 which is 20.5 . So, 8×20.5=164 dollars.
(8×20.5=164) 8 cents=10 (10×20.5=205)
164 dollars=205
Therefore,the answer is 164 dollars.

Factor 5x^2 + 16x – 16
Answers
Answer:
(x + 4)(5x - 4)
Step-by-step explanation:
[tex]5x^2 + 16x – 16 \\ = 5x^2 + 20x - 4x– 16 \\ = 5x(x + 4) - 4(x + 4) \\ = (x + 4)(5x - 4)[/tex]
Answer:
(5x - 4) • (x + 4)
Step-by-step explanation:
Multiply the coefficient of the first term by the constant 5 • -16 = -80
Find two factors of -80 whose sum equals the coefficient of the middle term, which is 16 .
Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -4 and 20
5x2 - 4x + 20x - 16
Add up the first 2 terms, pulling out like factors :
x • (5x-4)
Add up the last 2 terms, pulling out common factors :
4 • (5x-4)
Add up the four terms of step 4 :
(x+4) • (5x-4)
Which is the desired factorization

For the right triangles below, find the exact values of the side lengths a and c. If necessary, write your responses in simplified radical form.
Answers
Answer:
First triangle: [tex]a = 5\sqrt{2}[/tex], second triangle: [tex]c = \frac{8\sqrt{3}}{3}[/tex]
Step-by-step explanation:
In the first triangle, the value of [tex]a[/tex] is equal to the following trigonometric relation:
[tex]a = \frac{5}{\cos 45^{\circ}}[/tex]
[tex]a = \frac{5}{\frac{\sqrt{2}}{2} }[/tex]
[tex]a = \frac{10}{\sqrt{2}}[/tex]
[tex]a = \frac{10\sqrt{2}}{2}[/tex]
[tex]a = 5\sqrt{2}[/tex]
In the second triangle, we obtain the value of [tex]c[/tex] is equal to the following trigonometric relation:
[tex]c = 8\cdot \tan 30^{\circ}[/tex]
[tex]c = 8 \cdot \left(\frac{\sin 30^{\circ}}{\cos 30^{\circ}} \right)[/tex]
[tex]c = 8\cdot \left(\frac{\frac{1}{2} }{\frac{\sqrt{3}}{2} } \right)[/tex]
[tex]c = \frac{8}{\sqrt{3}}[/tex]
[tex]c = \frac{8\sqrt{3}}{3}[/tex]

Describe how to solve x−6=−12.
Answers
Answer:
See explanation.
Step-by-step explanation:
You have to use the inverse operation of -6 to get x by itself. So you have to add 6 to each side to get rid of the -6. And -12+6=-6. So, x=6.
Answer:
X is -6
Step-by-step explanation:
You have to add 6 to both sides like -6+6 and -12+6
-12+6=-6 which is the answer because -6-6 is -12
