Answer:
x = -4 3/5 or -4.6
Step-by-step explanation:
(x+4)/-5 = 3
Divide -5 from both sides
x + 4 = -3/5
Subtract 4 from both sides
x = -4 3/5

Answer:
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

what is the range of the function f(x)=-8x+13 when the domain is (-2,0,3)?
Answer:
The complete set of domain (x) and range values (y) is given by:
x y
-2 39
0 13
3 11
Step-by-step explanation:
Considering the function
[tex]f(x)=-8x+13[/tex]
As we know that the range of a function consists of the entire set of all possible resulting values of the dependent variable commanly called y or f(x), once we have substituted the domain.
Now
As the x values are -2, 0, and 3. So, the domain interval is (-2,0,3).Putting x = -2 in f(x) to determine the range for the value x = -2
[tex]f(x)=-8x+13[/tex]
[tex]f(-2)=-8(-2)+13=16+13=39[/tex]
Putting x = 0 in f(x) determine the range for the value x = 0
[tex]f(x)=-8x+13[/tex]
[tex]f(0)=-8(0)+13=0+13=13[/tex]
Putting x = 0 in f(x) determine the range for the value x = 3
[tex]f(x)=-8x+13[/tex]
[tex]f(3)=-8(3)+13=-24+13=11[/tex]
Therefore, the complete set of domain (x) and range values (y) is given by:
x y
-2 39

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?
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
Find the distance between the points (-4,-2) and (4,3)
Answer:
9.433981132
Step-by-step explanation:
To learn how to find the distance between two points by using the distance formula, which is an application of the Pythagorean theorem. We can rewrite the Pythagorean theorem as d=√((x_2-x_1)²+(y_2-y_1)²) to find the distance between any two points, and I used my calculator to do so.
Tim sells two types of pizza. He charges
$10 for a cheese pizza and $15 for a
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?
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.

What is an equation of the line that passes through the points (-3, 8) and (4, 1)?
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]

If 5 + 6i is a root of the polynomial function f(x), which of the following must also be a root of f(x)?
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).
Took the review test and passed.

Add 19 to ‘a’ and divide the sum by 5, you will get 8
Answer:
a = 21
Step-by-step explanation:
Given
[tex]\frac{a+19}{5}[/tex] = 8 ( multiply both sides by 5 to clear the fraction )
a + 19 = 40 ( subtract 19 from both sides )
a = 21
The speed of an object can be found by taking the distance it travels and dividing it by the time it takes to travel that distance. An object travels 100 feet in 2.5 seconds. Let the speed, , be measured in feet per second.Write an equation to represent the relationship between the three quantities (speed, distance, and time).
Answer:
We are given the rule: the speed is the ratio between the distance and the time. So we have
s = d/t = 100/2.5

Step 1: Define
g - 16 = 2
Step 2: Solve for g
Add 16 to both sides: g = 18Step 3: Check
Plug in g into the original equation to verify it's a solution.
Substitute in g: 18 - 16 = 2Subtract: 2 = 2Here we see that 2 does indeed equal 2.
