f(x) = x² + x + 39
f(50) = 50² + 50 + 39
f(50) = 2500 + 89
f(50) = 2589
What is the vertex of the following quadratic equation?
y = 7(x + 5)2 + 4
A. (5,4)
B. (-4,5)
C.(-5, 4)
D. (7,-4)
Answer:
C.(-5, 4)
Step-by-step explanation:
The vertex form of a parabola of this type is:
y = a ( x − h ) 2 + k [1]
where ( h , k ) is the vertex.
Explanation:
Given:
y = 7 ( x + 5 )² + 4 [2]
We can convert equation [2] into the same form as equation [1] by writing
+5 as − − 5 :
y = 7 ( x − − 5) ² + 4 [3]
We observe that the vertex is
( − 5 , 4 )

You want to frost a 13 in. by 9 in. cake that you just baked when you notice your little brother ate a piece right out of the middle. What area of cake is left to be frosted if he ate a 2 in. by 2 in. piece? no links pls :) thanks will give brainliest
Answer:
113 inches
Step-by-step explanation:
13 times 9 is 117 inches (this is the area for the whole cake)
2 times 2 is 4 (this is just the middle)
But since the brother ate the middle you will have to subtract the area of the middle piece from the whole area.
117-4 is 113 so the area now is 113 inches
Find M<1, M<2, M<3, M<4, M<5
Answer:
Step-by-step explanation:
m∠2 = 52° [Alternate interior angles]
m∠1 + m∠2 = 180° [Linear pair of angles are supplementary]
m∠1 = 180° - 52°
m∠1 = 128°
m∠3 = 47° [Alternate interior angles]
m∠5 + 52° + 47° = 180° [Sum of linear angles is 180°]
m∠5 = 180° - 99°
= 81°
m∠4 + 47° = 180° [Sum of consecutive interior angles is 180°]
m∠4 = 180° - 47°
m∠4 = 137°

The polygons are similar, but not necessarily drawn to scale. Find the value of x.
question 3/4
Answer:
i am having trouble with that too
Step-by-step explanation:
Answer:
Since we are told that the two given polygons are said to similar, their corresponding side lengths are proportional to each other.
so to solve
(x - 3)/2.5 = 16/4
(x - 3)/2.5 = 4
Multiply both sides by 2.5
x - 3 = 4 × 2.5
x - 3 = 10
Add 3 to both sides
x = 10 + 3
x = 13
So the value of x is 13.

Given
- 1 = [tex]\frac{d}{4}[/tex] ( multiply both sides by 4 to clear the fraction )
- 4 = d
Take a factor out of the square root:
Answer:
[tex]-y\sqrt{3}[/tex]
Step-by-step explanation:
Under the radical there is a perfect square, one can take the perfect square out, and write it by its square root. The result of taking the principal square root is always positive, but it is given that the perfect square factor is negative, thus, one must multiply the square root by the negative sign to ensure that the result is positive.
Answer:
[tex]-y\sqrt{3}[/tex]

which set of sides will NOT make a triangle?
19cm 14cm 7cm
11cm 13cm 3cm
12cm 7cm 5cm
2cm 3cm 4cm
Answer:
12cm 7cm 5cm
Step-by-step explanation:
Since 7 + 5 is = 12, it cannot be a side of a triangle. If you add any 2 numbers, the sum must be greater than the 3rd one.

Two number cubes are rolled.
What is the probability that the first lands on an odd number and the second lands on an even number?
Enter you answer, as a fraction in simplified form, in the box
Answer:
1/4
Step-by-step explanation:
Assuming the number cube is a six-faced die, you have
1 2 3 4 5 6
three odd numbers, and three even numbers. Therefore, the chance of it landing on an odd number or even number is 3/6, which equals 1/2. That means you have a 50% chance to get an odd number, or an even number.
So, you have two die. Both have a 50/50 chance of getting an even or odd number. So what's the chance of one landing on an odd number, and the other landing on an even number?
You would have a 25% chance for an even and then an even numberYou would have a 25% chance for an odd and then an odd numberYou would have a 25% chance for an even and then an odd numberYou would have a 25% chance for an odd and then an even number.25% as a simplified fraction is 1/4. Therefore, 1/4 is your answer.

Write the equation of the line in slope-intercept form passing through the points (-4,2) and (1,12)
Answer:
y = 2x + 10
Step-by-step explanation:
Find the slope:
12 - 2 / 1 - (-4)
10 / 5 = 2
Write in point-slope form:
y - 12 = 2(x - 1)
rearrange:
y - 12 = 2x - 2
y = 2x + 10

60 tickets to a concert was sold. Adult tickets cost $5 while children’s tickets cost $3.50. A total of $250 was collected. How many adult and children tickets were sold?
Answer:
Number of adults tickets sold = x
= 26.67 tickets
Number of children tickets sold = y = 33.33 tickets
Step-by-step explanation:
Let
Number of adults tickets sold = x
Number of children tickets sold = y
x + y = 60 (1)
5x + 3.50y = 250 (2)
From (1)
x = 60 - y
Substitute x = 60 - y into (2)
5x + 3.50y = 250
5(60 - y) + 3.50y = 250
300 - 5y + 3.50y = 250
- 5y + 3.50y = 250 - 300
- 1.50y = 50
y = -50/-1.50
y = 33.33
Substitute y = 33.33 into 1
x + y = 60
x + 33.33 = 60
x = 60 - 33.33
x = 26.67 tickets
Number of adults tickets sold = x
= 26.67 tickets
Number of children tickets sold = y = 33.33 tickets
