Answer:
Discriminant = -92
the equation has no distinct real numbers
Step-by-step explanation:
Given the function f(x) = 4x^2 + 2x + 6 where;
a = 4, b = 2 and c= 6
The discriminant is expessed as D = b^2 - 4ac
Substitute;
D = 2^2 - 4(4)(6)
D = 4 - 96
D = -92
Hence the discriminant is -92.
Since the discriminant is less than zero i.e D< 0, this shows that the zeros of the equation are not real but complex numbers. Hence, the equation has no distinct real numbers
Answer:
-92 is the discriminant
0 real value 0's

Answer:
A
Step-by-step explanation:
The bottom side of the smaller rectangle is marked 10, and the bigger one is marked 20. 20÷10=2, making this a 2:1 scale. Simply multiply the 8 on the right of the smaller rectangle by 2 and you'll get 16, the answer for the similar rectangle.
Answer:
A. 16 cm
Step-by-step explanation:
Since the rectangle on the left is 10 cm and the one on the right is 20, that means that it was multiplied by 2. So you multiply 8 by 2 and you get 16.

Answer:
y=5/2x-16
Step-by-step explanation:
First, we want to find the slope of the original line.
m= -4+8/-1-9
m= 4/-10
m= -2/5
Because we want the perpendicular bisector, we will need the slope to be the opposite reciprocal. Therefore, our slope is
m=5/2
Now, we want to find the midpoint of the line.
9-1/2
8/2=4
-8-4/2
-12/2= -6
So, the midpoint is (4,-6)
Using the information we have, we now can find b.
-6=5/2(4)+b
-6=10+b
-16=b
That gives us our equation
y=5/2x-16
The equation of line h is y = -2x + 1. If line h is dilated with a scale factor of 4 with respect to the origin, what is the equation of the new line?
Answer:
y = -2x + 4Step-by-step explanation:
Given line h:
y = -2x + 1Dilated line is parallel to original, so will have same slope of -2
y-intercept will change by a scale factor of 4:
(0, 1) → (0*4, 1*4) = (0, 4)So the equation of the new line is:

Answer:
48%28mil%2Fh%29
Step-by-step explanation:
if car travels %282%2F5%29mil%2F%281%2F2%29min =>2%282%2F5%29%28mil%2Fmin%29=%284%2F5%29%28mil%2Fmin%29
since 1h=60min multiply %284%2F5%29mil by 60 to get the number of miles per hour %284%2Fcross%285%29%29cross%2860%2912%28mil%2Fh%29=4%2A12%28mil%2Fh%29=48%28mil%2Fh%29
Answer:
48 miles
Step-by-step explanation:
1h = 60m
[tex]\frac{1}{2}[/tex]m --- [tex]\frac{2}{5}[/tex]miles
0.5m --- [tex]\frac{2}{5}[/tex]miles
60m --- [tex]\frac{60}{0.5}[/tex] × [tex]\frac{2}{5}[/tex]miles
= 48 miles
On Wednesday at camp, Melissa went for a hike at 6:30 A.M. The hike took 2 hours and 55 minutes. As soon as she got back from the hike, Melissa played volleyball for 1 hour. What time did Melissa finish playing volleyball
Answer:
10:25 AM
Step-by-step explanation:
Solving the question above, we are total that:
On Wednesday at camp, Melissa went for a hike at 6:30 A.M. The hike took 2 hours and 55 minutes. As soon as she got back from the hike, Melissa played volleyball for 1 hour.
The time that Melissa finished playing volleyball is calculated as:
6:30AM + 2 hours 55 minutes + 1 hour
= 6:30 am + 3 hours 55 minutes
= 9:85 minutes
60 minutes = 1 hour
85 minutes = 1 hour 25 minutes
= 10:25 AM
Hence: Melissa would finish playing volleyball at 10:25 AM

ANSWER ASAP!!! Which table correctly lists the reasons to prove <1 = <3, given that AB intersects CD?
Answer: B
Step-by-step explanation:
Took the test
First table correctly list the reasons.
Given from fig two lines intersect each other and form angles as shown in fig.
Now we have to prove angle 1 equals to angle 3.
From table first all the step by step statement and reasons are correct but in table second 4th statement is correct but its reason is wrong. similarly in 3rd table 5th statement is correct but its reason is wrong.
So we can say now first table is correctly list the reasons to prove angle 1 equals to angle 2.

Enter the value of p so the expression 4(n+7) is equivalent to (n+p)4.
Answer:
p=7
Step-by-step explanation
both n and 4 are in both so p will have to be the same thing as 7 in order to be equal
The value of p that makes the expressions 4(n+7) and (n+p)4 equivalent is p = 7.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To make the expressions 4(n+7) and (n+p)4 equivalent, we need to distribute the 4 in the second expression, which gives us:
(n+p)4 = 4n + 4p
Now we can set this expression equal to 4(n+7) and solve for p:
4n + 4p = 4(n+7)
Simplifying both sides:
4n + 4p = 4n + 28
Subtracting 4n from both sides:
4p = 28
Dividing both sides by 4:
p = 7
Therefore,
The value of p that makes the expressions 4(n+7) and (n+p)4 equivalent is p = 7.

Can anyone show me how to solve this problem? I know that its 5 weeks. (The problem is “Ahmed is saving his money to buy a Ipad that costs $319.50. Right now he has $21.95, and can save $63.00 each week. How many weeks will it take for Ahmed to have enough money to buy the Ipad)
Answer:
5 weeks
Step-by-step explanation:
Substract 319.5 (the amount he has to save) to the amount he has already saved, which is 21.95. Now the constant amount of change is 63 dollars each week so divided it by that. So the equation should be (319.5-21.95) and divide all that by 63 to get 4.72 or rounded to the nearest number, is 5.

20/17, 13/17
Answer:
13/17, 20/17
Step-by-step explanation:
3x + 4y = 7 --- Equation 1
Equation 1×5:
15x + 20y = 35 --- Equation 2
------------------------------------------------------------------------------------------------------------
8x + 5y = 12 --- Equation 3
Equation 3×4:
32x + 20y = 48 --- Equation 4
------------------------------------------------------------------------------------------------------------
Equations 4-2:
32x + 20y - 15x - 20y = 48 - 35
17x = 13
x = [tex]\frac{13}{17}[/tex]
Substitute x = [tex]\frac{13}{17}[/tex] into Equation 1:
3x + 4y = 7
3([tex]\frac{13}{17}[/tex]) + 4y = 7
[tex]\frac{39}{17}[/tex] + 4y = 7
4y = 7 - [tex]\frac{39}{17}[/tex]
= [tex]\frac{119}{17}[/tex] - [tex]\frac{39}{17}[/tex]
= [tex]\frac{80}{17}[/tex]
y = [tex]\frac{80}{17}[/tex] ÷ 4
y = [tex]\frac{20}{17}[/tex]
Thus, x = [tex]\frac{13}{17}[/tex], y = [tex]\frac{20}{17}[/tex].

Step-by-step explanation:
-To solve what the distance is, you can use the formula:
d = st, where the distance is equal to the speed times the time.
-Plug the values into the formula (60mph is the speed, and 9 hours is the time):
d = 60(9)
-Solve it to get:
d = 540

$16.98 with buy one get one 50% off (SHOW WORK)
Answer:
$8.49
Step-by-step explanation:
Amount Saved = $8.49 (answer). In other words, a 50% discount for a item with original price of $16.98 is equal to $8.49 (Amount Saved).
Since we know that an object is 16.98, all we need to do is find what 50% is off the cost. Since 50% is half of the price, all we need to do is come up with the equation:
[tex]16.98/2= 8.49 + 16.98 = 25.47[/tex]
I added 16.98 at the end because you have to buy One *object* and get it with half price. The total with the discounted object is 25.47
