Answer:
y = 1/2x + 8
Step-by-step explanation:
y2 - y1 / x2 - x1
9 - 10 / 2 - 4
-1 / -2
= 1/2
y = 1/2x + b
10 = 1/2(4) + b
10 = 2 + b
8 = b

the slope of _____ lines to 0.
Answer:
A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0). because division by zero is an undefined operation

A system of equations is given below. For what value(s) of x is f(x)=g(x) ?
f(x)=x2+3x
g(x)=x+3
[tex] \large{f(x) = g(x)} \\ \large{ {x}^{2} + 3x = x + 3}[/tex]
Since we are solving the quadratic equation because the highest degree in the equation is second. We arrange in the form of ax²+bx+c = 0.
[tex] \large{ {x}^{2} + 3x - x - 3 = 0}[/tex]
Combine like terms.
[tex] \large{ {x}^{2} + 2x - 3 = 0}[/tex]
Solve the equation by factoring.
[tex] \large{(x + 3)(x - 1) = 0} \\ \large{x = - 3,1}[/tex]
Hence the values of x that make f(x) = g(x) are -3 and 1.
Answer
x = -3,1Let me know if you have any doubts!

distributive property
addition property of equality
subtraction property of equality
division property of equality
Answer:
distribute property
Step-by-step explanation:
5 is distributed into the parentheses.
5 × x = 5x
5 × (-7) = -35
5x - 35 = 55
Hope that helps.
The property used in step 1 to arrive at step 2 is the Distributive property, the correct option is A.
What is a Product?Product is the output of the mathematical operation Multiplication.
The Step 1: 5 (x minus 7) = 55.
Step 2: 5 x minus 35 = 55
In step 2 Distributive property is used to solve the expression.
According to Distributive property
The sum of multiplying a number by the addend of two numbers will the same result when each number which is being added is multiplied individually and then added.
a ( b+c) = a*b + a*c
5 (x -7) = 55.
5x - 35 = 55
Therefore, the distributive property is used.

Given:
The figure of a circle O.
To find:
The value of x.
Solution:
First, label some points on the given figure as shown below.
In triangle BOC,
[tex]OB=OC[/tex] (Radii of same circle)
It means [tex]\Delta BOC[/tex] is an isosceles triangle and the base angles of an isosceles triangles are congruent. So,
[tex]\angle OBC\cong \angle OCB[/tex]
[tex]m\angle OBC=m\angle OCB[/tex]
[tex]75^\circ=m\angle OCB[/tex]
In triangle [tex]\Delta BOC[/tex],
[tex]m\angle BOC+m\angle OBC+m\angle OCB=180^\circ[/tex] (Angle sum property)
[tex]m\angle BOC+75^\circ+75^\circ=180^\circ[/tex]
[tex]m\angle BOC+150^\circ=180^\circ[/tex]
[tex]m\angle BOC=180^\circ-150^\circ[/tex]
[tex]m\angle BOC=30^\circ[/tex]
Now,
[tex]m\angle BOC=m\angle BOC+m\angle COD[/tex]
[tex]m\angle BOC=30^\circ+94^\circ[/tex]
[tex]m\angle BOC=124^\circ[/tex]
Using the central angle theorem, we get
[tex]m\angle BAD=\dfrac{1}{2}\times m\angle BOD[/tex]
[tex]x=\dfrac{1}{2}\times 124^\circ[/tex]
[tex]x=62^\circ[/tex]
Therefore, the correct option is B.

This system of inequalities models the scenario:
2x + y ≤ 8
x + y ≥ 4
Part A: Describe the graph of the system of inequalities, including shading and the types of lines graphed. Provide a description of the solution set.
Answer:
Solution set include (1,5), (1,4)
Step-by-step explanation:
To solve, you would have to graph both lines, and shade, the sections that are applicable. For Example is if it tells you the 2x+y is less than or equal to 8, you would shade it.
The Solution set would be anything in the overlapping area between both line's shades.

On Saturday, the fruit and juice bar was selling 20 glasses of fruit punch an hour. By 7 p.m., they had sold 180 glasses. If their goal was to sell more than 240 glasses of fruit punch, find the number of hours, h, they must stay open past 7 p.m. to make their goal.
======================================================
Explanation:
h = number of hours past 7 pm
20h = the number of glasses sold after h hours
20h+180 = adding on the 180 glasses already sold
20h+180 > 240 is the inequality to set up
Let's solve for h
------------------
20h+180 > 240
20h > 240-180
20h > 60
h > 60/20
h > 3
They must remain open more than 3 hours past 7 pm in order to sell more than 240 glasses of juice.
The earliest that they can close is 11 pm (since 4+7 = 11).
--------------------
If h = 3, then
20h+180 = 20*3 + 180 = 240
meaning that they haven't reached their goal of getting over 240
So they have to stay open that extra hour to get past 240.

A florist arranges some orchids in bouquets of 20 and some roses in bouquets of 10. She sells each orchid bouquet for $25 and each rose bouquet for $30. She earns a total of $390. If she sells four times as many orchid bouquets as rose bouquets, how many flowers does she sell altogether?
Answer:
270 flowers total she sell Together.
Step-by-step explanation:
According to the Question,
Given, A florist arranges some orchids in bouquets of 20 and some roses in bouquets of 10.Let, x = number of orchid bunches & y = number of rose bunches.
Now, She sells each orchid bouquet for $25 and each rose bouquet for $30. She earns a total of $390Therefore, 25x + 30y = 390 ⇒⇒ Equation 1
she sells 4 times as many orchid bunches as rose bunches,
Therefore, x = 4y ⇒⇒ Equation 2
Put The Value Of Equation 2 in Equation 1, We get25 × (4y) + 30y = 390
100y + 30y = 390
130y = 390 ⇔ y = 390 / 130 ⇒ 3
if y = 3, then x = 4y must be equal to x= 12.
Thus, she sold 12 orchid bunches and 3 rose bunches.
Verify, 25x + 30y = 390 ⇔ 12 × 25 + 3 × 30 = 390 (All okay)Now, Each orchid bunch contains 20 flowers and each rose bunch contains 10 flowers.
12 × 20 + 3 × 10 = 240 + 30 ⇔ 270 flowers total she sell Together.PLEASE help !! someone who knows fr ! pls

What is the solution to this equation?
X-7 = 18
A. X= 25
B. X = 35
c. x = 9
D. X= 1)
Answer:
x = 25
Step-by-step explanation:
X-7 = 18
Add 7 to each side
X-7+7 = 18+7
x = 25
Given that,
X-7 = 18
Now we can add 7 to each side,
→ X-7 + 7 = 18+7
→ x = 25
So, option (A) is the correct answer.

The shortest side of an isosceles triangle is labeled, in inches, in the triangle below. The two longer sides are 6 inches longer than the shortest side. The perimeter of the triangle is 33 inches.
Complete question is;
The shortest side of an isosceles triangle is 2x - 3 inches long. the longer sides are 6 inches longer than the shortest side. the perimeter of the triangle is 33 inches. what is the length of each side of the longer sides of the triangle.
Answer:
Shortest side = 7 inches
Side 2 = 13 inches
Side 3 = 13 inches
Step-by-step explanation:
We are told that;
Triangle is isosceles
The shortest side is 2x - 3 inches
The other 2 sides which are equal because it's an isosceles triangle are both 6 inches longer than the shortest side. Thus;
Side 2 = side 3 = 2x - 3 + 6 = 2x + 3
Since perimeter = 33 and sum of all 3 sides is the perimeter. Thus;
(2x - 3) + 2x + 3 + 2x + 3 = 33
6x + 3 = 33
6x = 33 - 3
6x = 30
x = 30/6
x = 5
Thus;
Shortest side = 2(5) - 3 = 7
Other 2 sides are each; 2(5) + 3 = 13
