Step-by-step explanation:
Write the equation of the line that has a slope of -4 and passes through the point (-2,-5).
Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 4 , then
y = - 4x + c ← is the partial equation
To find c substitute (- 2, - 5) into the partial equation
- 5 = 8 + c ⇒ c = - 5 - 8 = - 13
y = - 4x - 13 → B

What is the area of 9yd and 5yd and how’d you get it
9514 1404 393
Answer:
45 yd²
Step-by-step explanation:
The area of a rectangle is the product of its length and width. If your given measures are the length and with of a rectangle, the area is found by multiplying them.
A = LW
A = (9 yd)(5 yd) = 9·5 yd·yd = 45 yd²
The area of a 9 yd by 5 yd rectangle is 45 square yards.

1. Javier is determining the exact zeros for f(x) = x2 – 14x + 19.
His work is shown.
a. Identify the error Javier made when
determining the zeros.
Answer:
The last line is
[tex]x = 7 + - \sqrt{30} [/tex]
The roots of f(x) are 7+root 30 and 7 -root 30.
We have given that the quadratic equation is
[tex]f(x)=x^2-14x+19[/tex]
We have to find the zeros of the given f(x)
Compaire the given equation with the general form of quadratic equation
What is the general form of quadratic equation?[tex]ax^2+bx+c=0[/tex]
So we get,a=1,b=-14,c=19
We find the roots by using the quadratic formula method
What is the quadratic formula ?[tex]x_{1,2}=\frac{-b\±\sqrt{b^2-4ac} }{2a}[/tex]
Use the value of a,b and c in above formula we get,
[tex]x_{1,2}=\frac{-(-14)\±\sqrt{(-14)^2-4(1)(19)} }{2(1)}[/tex]
[tex]x_{1,\:2}=\frac{-\left(-14\right)\pm \:2\sqrt{30}}{2\cdot \:1}[/tex]
[tex]x_1=\frac{-\left(-14\right)+2\sqrt{30}}{2\cdot \:1}[/tex]
[tex]=\frac{14+2\sqrt{30}}{2}[/tex]
[tex]=\frac{14+2\sqrt{30}}{2}[/tex]
[tex]=\frac{2\left(7+\sqrt{30}\right)}{2}[/tex]
[tex]=7+\sqrt{30}[/tex]
Similarly, we get,
[tex]x_2=\frac{-\left(-14\right)-2\sqrt{30}}{2\cdot \:1}[/tex]
[tex]x_2=7-\sqrt{30}[/tex]
Therefore the roots of f(x) are 7+root 30 and 7 -root 30.

a) Find the gradient of a line perpendicular to line AB.
Step-by-step explanation:
the gradient for the line perpendicular to AB is 3The slope of the line that is perpendicular to the line of AB is: 3.
What is the Slope of Perpendicular Lines?If two lines are perpendicular to each other, their slopes will be the negative reciprocal of each other. i.e., if the slope of one is 3, the slope of the other would be -1/3.
Slope = change in y / change in x
Slope of AB = (-2 - 2) / (7 -(-5))
Slope of AB = -4/12
Slope of AB = -1/3
Negative reciprocal of -1/3 would be 3.
Therefore, the slope of the line that is perpendicular to the line of AB is: 3.

7.5cm2
Step-by-step explanation:
5x3cm=15cm2 because of base x height/2 you would do
15cm2 divided by 2 since it is a triangle (a half of a square) which is 7.5cm2
Answer:
D.
Step-by-step explanation:
Area of a triangle is bh/2
So your base is 5 and your height is 3.
So you do 5*3 which is 15.
And lastly you do 15/2, which is 7.5. 7*2 is 14, and 8*2 is 16
So 7.5 times 2 is 15
Sam and Dean are brothers. Their ages now add up to the age of their sister. In ten years, Dean's age will be the sum of their ages today. How old are each of them?
Answer:
Sam is yeas old, and Dean is (x - 10) year's old, where 'x' is the age of their sister
Step-by-step explanation:
The relationship between the ages of the brothers are;
Sam's age + Dean's age = Their sister's age
Dean's age + 10 = Dean's age + Sam's age
Therefore, we have;
Sam's age = Dean's age + 10 - Dean's age = 10
Sam's age = 10 years
Let 'x' represent their sisters age, we get;
Sam's age + Dean's age = x
10 + Dean's age = x
Dean's age (in variable form) = x - 10
The Malcolms are taking a trip. Midville is 214 miles
from their home. Walesburg is 3 times as far.
How far is Walesburg from their home?
Answer:
642 miles
Step-by-step explanation:
Distance of Midville from their home = 214 miles
Walesburg is 3 times as far.
How far is Walesburg from their home?
Distance of Walesburg from their home = 3 × Distance of Midville from their home
= 3 × 214 miles
= 642 miles
Distance of Walesburg from their home = 642 miles
What is the measure of angle B
Answer:
Step-by-step explanation:
angle C + Angle B= Angle A(sum of two interior oppposite angles are equal to the exterior angle formed)
61+B=143
B=143-61
B=82 degree
We know that,
→ C = 61°
[A = B + C]
→ 143° = B + 61°
→ B = 143° - 61°
→ B = 82°
[180° = A + B + C]
→ 180° = A + (82° + 61°)
→ A = 180° - 143°
→ A = 37°

Jesse needs 10 1/4 feet of chain to complete an outdoor project. He has two small pieces each measuring 2 1/8 feet and a third piece measuring 3 3/4 feet. How many feet of chain does Jesse need to purchase?
Answer:
= 2 1/4 feet
Step-by-step explanation:
Length of chain Jesse needs = 10 1/4 feet
Length of chain Jesse has:
Two small pieces each measuring 2 1/8 feet
= 2 × 2 1/8 feet
= 2 × 17/8
= 34/8 feet
Third piece measuring 3 3/4 feet
Total Length of chain Jesse has = 34/8 feet + 3 3/4 feet
= 34/8 + 15/4
= 34+30/8
= 64/8
= 8 feet
Total Length of chain Jesse has = 8 feet
Length of chain Jesse needs to purchase = Length of chain Jesse needs - Total Length of chain Jesse has
= 10 1/4 feet - 8 feet
= 2 1/4 feet
Length of chain Jesse needs to purchase = 2 1/4 feet

Roció hará un circulo con un diámetro de 22.8 cm cuánto medirá un radio
Answer:
r = 11.4 cm
Step-by-step explanation:
The question says that, "Spray will make a circle with a diameter of 22.8 cm how long a radius will measure."
Given that,
The diameter of the circle, d = 22.8 cm
We know that the relation between the diameter and the circle is given by :
d = 2r
Where
r is the radius of the circle
r = d/2
r = 22.8/2
r = 11.4 cm
So, the radius of the circle is equal to 11.4 cm.
8. Select all the numbers that irrational
Answer:
Answers are square root of 2, square root of 7,
Step-by-step explanation:
Irational is a number that is never ending.
Square root of 2 is irrational since there is no pattern to the number after the decimal.
10/ sqrt of 100. Sqrt of 100 is 10. 10/10 = 1 so this is not a irrational.
Sqrt of 7 does not have a pattern after the decimal point so it is irrational.
5.87 with a dash on top is rational since it means it has a pattern of continues 87's.
Last one it is equal to 2 so it is rattional.
Answer:
The square root of 2 is irrational, also 5.87 repeating, the square root of 7 and the other two options aren't irrational.
Step-by-step explanation:
Irrational numbers definition: a number that can be expressed as an infinite decimal with no set of consecutive digits repeating itself indefinitely and that cannot be expressed as the quotient of two integers

A car tire with a diameter of 1.6 ft rotates 275 degrees . How far does a point on the circumference of the tire travel
Answer:
A point on the circumference of the tire will travel 7.68 ft.
Step-by-step explanation:
Given;
radius of the car tire, r = 1.6 ft
angular distance or rotation = 275⁰
A complete rotation of the tire = 360⁰
the distance a point on the circumference will travel = 2πr
If 360⁰ = 2πr
then 275⁰ = ?
[tex]= \frac{275 \ \times \ 2\pi r}{360} = \frac{275 \ \times \ 2\pi \times 1.6ft}{360} = 7.68 \ ft[/tex]
Therefore, a point on the circumference of the tire will travel 7.68 ft.

Given
[tex]l = 9.6cm[/tex] --- side length
[tex]a = 11cm[/tex] --- apothem
[tex]n = 5[/tex]
Required
The height of the prism
The apothem of a prism is:
[tex]a = \frac{l}{2\tan(\frac{180}{n})}[/tex]
There are no direct links between the apothem, the height and the side lengths of a prism.
To calculate the height, we will need to the base area and the volume of the prism.
Hence, more details are needed.
