Brad’s checking account starts off with a balance of $126.50. Throughout the week, Brad pays a bill for $87.21 and pays $5.64 for breakfast. He deposits $15.00 but then pays another bill for $55.25. At the end of the week, he gets a notice from the bank that he has a negative balance. How much does Brad need to deposit into his account to get to a $0 balance?
Answers
Answer:
$6.60
Step-by-step explanation:
Answer:
$6.6
Step-by-step explanation:
We add the amount he paid,
($87.21 + $5.64) - $15.00 + 55.25
We will get ,
$92.85 - $15.00 + $55.25
Then,
$77.85 + $55.25
We will get,
$133.10, the subtract the $133.10 from his original balance and get
$126.50 - $133.10 = $-6.6
He will need to deposit $6.6 to get his account to $0 balance
If 5 + 6i is a root of the polynomial function f(x), which of the following must also be a root of f(x)?
Answers
Answer:
5-6i
Step-by-step explanation:
The complex conjugate root theorem states that if (a+bi) is a root, then (a-bi) must also be a root and vice versa.
We know that (5+6i) is a root.
Then by the above theorem, (5-6i) must also be a root.
Hence, our solution is (5-6i).
The answer is (B).

for a given input value of n, the function h outputs a value of m to satisfy the following equation.
m+1=-2(n+6)
write a formula for h (n) in terms of n
h(n)=
Answers
Answer:
h(n) = - 2n - 13
Step-by-step explanation:
Given
m + 1 = - 2( n + 6) = - 2n - 12 ( subtract 1 from both sides )
m = - 2n - 13, that is
h(n) = - 2n - 13

AE:[tex]\sqrt{15300}[/tex]
DE:150
PABCDE: 720
Step-by-step explanation:
We can find AE by the pythagorean theorem, [tex]a^{2}+b^{2}=c^{2}[/tex]
AE is the hypotenuse so AE=c, and the leg of the triangle would be 150-30=120
[tex]50^{2}+120^{2}=c^{2}[/tex]
c^2=2500+14400
AE=130
We can use the pythagorean theorem again to find DE.
The base would equal 140-50=90 and the height would equal 120
[tex]90^{2} +120^{2} =DE^{2}[/tex]
DE^2=22500
DE=150
The perimeter would be 150+140+150+130+150=720

pepperoni pizza. Yesterday he sold
64 pizzas in all. For every cheese pizza,
he sells 3 pepperoni pizzas. How much
money did he make selling pizzas
yesterday?
Answers
Answer:
answer must be $880.
48 papperoni pizza =48 * 15= 720
16 cheese pizza =16 * 10= 160
Total sell =$880
He make $880 for selling pizzas yesterday.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Tim sells two types of pizza. He charges $10 for a cheese pizza and $15 for a pepperoni pizza.
And, Yesterday he sold 64 pizzas in all. For every cheese pizza, he sells 3 pepperoni pizzas.
Now,
Since, For every cheese pizza, he sells 3 pepperoni pizzas.
Hence, Let number of cheese pizza = x
Then, Number of pepperoni pizzas = 3x
Since, Yesterday he sold 64 pizzas in all.
So, We get;
⇒ x + 3x = 64
⇒ 4x = 64
⇒ x = 16
Thus, Number of cheese pizza = x = 16
Then, Number of pepperoni pizzas = 3x
= 3 × 16
= 48
So, The cost of 16 cheese pizza and 48 pepperoni pizza are;
⇒ Total cost = 16 × $10 + 48 × $15
⇒ Total cost = $160 + $720
⇒ Total cost = $880
Thus, He make $880 for selling pizzas yesterday.

measure
Answers
Answer:
we conclude that:
If the scale factor > 1, the image is stretchedIf the scale factor < 1, the image is reducedIf the scale factor = 1, the image and object will be congruentStep-by-step explanation:
A dilation is a transformation which generates an image that is the same shape as the original object but in a different size.
The image can be obtained by multiplying the measure of the original object by a scale factor.
If the scale factor > 1, the image is stretched
If the scale factor < 1, the image is reduced
If the scale factor = 1, the image and object will be congruent
For example, if we multiply the measure of the coordinates of the vertex A(2, 2) of a triangle by a scale factor of 2, the image A' is stretched as the scale factor > 1.
Dilation with scale factor 2, multiply by 2.
(x, y) → (2x, 2y)A(2, 2) → (2(2), 2(2)) = A'(4, 4)
So, the image point A'(4, 4) is enlarged.
Dilation with scale factor ½, multiply by ½.
(x, y) → (½x, ½y )A(2, 2) → (2(1/2), 2(1/2)) = A'(1, 1)
So, the image point A'(1, 1) is reduced.
Therefore, we conclude that:

–24 + 12d = 2(d – 3) + 22
–24 + 12d = 2d - 6 + 22
–24 + 12d = 2d + 16
–24 + 12d - 2d = 16

1.) Select the correct equation for the following situation. Mariana had 134
crystals in her collection. This was 38 less than Rajesh's collection. How
many crystals are in Rajesh's collection?
38r = 134
r+ 38 = 134
r - 38 = 134
38 - r = 134
Answers
Answer:
r minus 38 equals to 134 this might be m not certain
The correct equation is, [tex]r-38=134[/tex] and Rajesh have 172 crystals .
Let us consider that, Rajesh had r crystals.
Mariana had 134 crystals in her collection.
Since, Rajesh has 38 more crystal than Marina . So , if we subtract 38 from crystals Rajesh have then both have equal number of crystals.
So, [tex]r-38=134[/tex]
Now, find crystals present in Rajesh collection.
[tex]r-38=134\\\\r=134+38=172[/tex]
Thus, Rajesh have 172 crystals .

What is an equation of the line that passes through the points (-3, 8) and (4, 1)?
Answers
Answer:
The equation of the line is:
[tex]y=-x+5[/tex]
Step-by-step explanation:
Given the points
(-3, 8)(4, 1)Finding the slope between the points
[tex]\left(x_1,\:y_1\right)=\left(-3,\:8\right),\:\left(x_2,\:y_2\right)=\left(4,\:1\right)[/tex]
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{1-8}{4-\left(-3\right)}[/tex]
[tex]m=-1[/tex]
Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope
substituting the values m = -1 and the point (-3, 8)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-8=-1\cdot \left(x-\left(-3\right)\right)[/tex]
[tex]y-8=-\left(x+3\right)[/tex]
Add 8 to both sides
[tex]y-8+8=-\left(x+3\right)+8[/tex]
[tex]y=-x+5[/tex]
Therefore, the equation of the line is:
[tex]y=-x+5[/tex]
