Find the slope and the y-intercept of the graph of the linear equation. y = −7x + 2 *
Answer:
slope = - 7, y- intercept = 2
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 )
y = - 7x + 2 ← is in slope- intercept form
with slope m = - 7 and y- intercept c = 2

12x - 8 = 8x - 20
Answer:
x= -3
Step-by-step explanation:
12x-8x = -20+8
4x = -12
x= -12/4
x = -3
Steps:
Step 1: Subtract 8x from both sides.
12x−8−8x=8x−20−8x
4x−8=−20
Step 2: Add 8 to both sides.
4x−8+8=−20+8
4x=−12
Step 3: Divide both sides by 4.
4x/4 = −12/4
Answer: x=−3

Mr. Landry, the owner of Blissful Bites Bakery, prepares 30 pounds of cake batter each morning. Mr. Landry uses half of the cake batter to make large cupcakes. If he makes 48 cupcakes, how many ounces of cake batter does he use for each cupcake?
Answer:
5 ounces
Step-by-step explanation:
Mr. Landry prepares 30 pounds of cake batter each morning and he uses half of the cake batter to make large cupcakes.
This means that he uses 15 pounds of cake batter.
He makes 48 cupcakes with the batter.
Therefore, the number of pounds of batter he uses per cake is:
15 / 48 = 0.3125 pounds
We have to convert it to ounces.
1 pound = 16 ounces
=> 0.3125 pounds = 16 * 0.3125 = 5 ounces
He uses 5 ounces of cake batter for each cake.
Answer:
5 ONCES

The following are the ages (years) of 5 people in a room: 15, 17, 22, 14, 19 A person enters the room. The mean age of the 6 people is now 19. What is the age of the person who entered the room?
Answer:
27
Step-by-step explanation:
Given that:
(15+17+22+14+19+x) divided by 6 = 19
(87 + x) divided by 6 = 19
87 +x = 114
so x = 27.
Therefore the age of person 6 = 27

The polynomial f(x) is written in factored form: f(x) = (x − 3)(x + 8)(x − 11) What are the zeros of the polynomial function?
x = 3, x = 8, x = 11
x = 3, x = −8, x = 11
x = −3, x = 8, x = −11
x = −3, x = 3, x = −8, x = 8, x = −11, x = 11
Answer:
x=3 x = -8 x = 11
Step-by-step explanation:
f(x) = (x − 3)(x + 8)(x − 11)
Using the zero product property
0 = (x − 3)(x + 8)(x − 11)
0 = x-3 0 = x+8 0 = x-11
x=3 x = -8 x = 11
Answer:
x=3 x = -8 x = 11

M(angle)1 =. Degrees
Answer:
Angle [tex]m\angle 1 = 35^o[/tex]
Step-by-step explanation:
Our goal is to find appropriate symmetries within the given diagram, so we can use the property of the addition of internal angles of a triangle that render [tex]180^o[/tex].
So we start by drawing a line that goes through the center of the circle and also through the vertex of angle [tex]m\angle 1[/tex]. Please see the attached image to follow the procedure. In the image, the line is a fine black line that crosses the circle completely.
Now we draw the four radii that will define clearly the central angles of [tex]100^o[/tex] and [tex]30^o[/tex] that come as information.
Then we set our efforts to analyze the two triangles (one marked with green borders, and the other one marked with orange borders. Notice that the angle on the further right for the triangle with orange borders is in fact half of the angle [tex]m\angle 1[/tex] that we need to find, so we will work our way to determine the size of it and then multiply it by two.
We need to start though with the triangle with green borders because it has more information that we can derive.
Notice that this green triangle has a central angle equal to [tex]115^o[/tex], because it has to measure the same as 180 degrees minus half of the 100 degrees angle and minus half of the 30 degree angle in order to add to form the perfect plane angle of the circle's diameter:
[tex]180^o-50^o-15^o=115^o[/tex]
Now, notice as well that this green triangle is an isosceles triangle (has two equal sides (both equal to the radius of the circle), and therefore the angles opposite to them must be equal. We can find the measure of either such angles by using the property of additions of internal angles of a triangle to render [tex]180^o[/tex], subtracting from it the 115 degree angle we know, and dividing the result by two:
[tex]180^o-115^o=65^o[/tex]
half of this is [tex]32.5^o[/tex]
Now we use this angle, to find its supplementary angle, which would be the angle on top of the orange triangle:
[tex]180^o-32.5^o=147.5^o[/tex]
Now all we need is to use the property of addition of internal angles for the orange triangle (of which we currently know a 15 degree angle and a 147.5 degree angle) to find what half of angle [tex]m\angle 1[/tex] is:
[tex]180^o-147.5^o-15^o=17.5^o[/tex]
then angle [tex]m\angle 1[/tex] is twice this value: [tex]m\angle 1 = 35^o[/tex]

C. 23041 units
O D. 19271 units3
Answer:
answer is B
Step-by-step explanation:
Volume of the sphere is 2.304[tex]\pi[/tex] unit³ or 7234.56 unit³.
What is a sphere ?A sphere is a three dimensional solid shape. It is a set of points that are all at the same distance r from a common point. The distance r is the radius and the common point is the centre of the sphere.
Here,
The radius of the sphere is given by,
r = 12 units
The equation for volume of a sphere with radius r is given by,
V = 4/3 [tex]\pi[/tex]r³
So, the volume of the sphere is,
V = 4/3 x [tex]\pi[/tex] x 12³
V = 2.304 [tex]\pi[/tex]
V = 7234.56 unit³
Hence,
Volume of the sphere is 2.304[tex]\pi[/tex] unit³ or 7234.56 unit³.

Answer:
[tex]x=\frac{\sqrt{13}-7 }{18} ,x=\frac{-\sqrt{13}-7 }{18}[/tex]
Step-by-step explanation:
I'm not too good with the quadratic formula so I'm going to complete the square.
First divide everything by 9 and move the 1 to the other side.
[tex]x^2-\frac{7}{9}=-\frac{1}{9}[/tex]
Then take half of [tex]\frac{7}{9}[/tex] and square it and add it to both sides.
[tex]x^2-\frac{7}{9} +\frac{49}{324}=\frac{13}{324}[/tex]
Now you can factor it.
[tex](x-\frac{7}{18})^2=\frac{13}{324}[/tex]
Square root:
