Answer:
Slope = [tex]\frac{1}{2}[/tex] , X-intercept = 8 , Y-intercept = -4
Step-by-step explanation:
the following equation is given in slope intercept form which is y = mx + b where m is the slope and b is the y intercept
since m = [tex]\frac{1}{2}[/tex] and b = -4, we can say our slope is [tex]\frac{1}{2}[/tex] and y intercept is -4.
Recall that x intercept occurs when y = 0 so plug y = 0 in the equation then solve for x
0 = [tex]\frac{1}{2}[/tex]x - 4
add 4 to both sides,
4 = [tex]\frac{1}{2}[/tex]x
multiply by 2 on both sides,
4*2 = x
8 = x
x = 8
so our x-intercept is 8

The number of peach trees in the orchard is directly proportional to
the number of apple trees. When Farmer Bob planted 40 peach
trees, he planted 120 apple trees. Everything was killed in the
drought and he's starting anew. How many apple trees will he
need to plant if he plants 500 peach trees?
Answer:
there was a difference between the 40 and 120 which was 80 so if there are 500 peach trees he would need to plant 580 because you add the difference to the total. The answer is 580 apple trees

An online furniture store sells chairs for $200 each and tables for $650 each. The store must sell no less than $12000 worth of chairs and tables each day. Write an inequality that could represent the possible values for the number of tables sold, tt, and the number of chairs sold, cc, that would satisfy the constraint.
The inequality that represents the possible values for the number of tables sold, tt, and the number of chairs sold, cc is $200cc + $650tt > $12,000.
What is the inequality ?Here are inequality signs and what they mean:
> means greater than< means less than≥ means greater than or equal to ≤ less than or equal tototal cost of chairs sold + total cost of tables sold > $12,000

A food pantry is making packages. Each package weighs 64 pounds. Each package contains 4 identical bags of rice and a 7-pound bag of beans. Write an equation to represent the situation.
Answer: ( . is another way to write a multiplication sign.
X = the amount of pounds each rice bag has.)
7 + 4 . X = 64
Not sure if this is needed but X = 14.25 so if there is a follow up question that asks how many pounds are in each bag of rice the answer would be 14.25.
If you can not use X in the equation another way of writing it would be 7 + 4 . 14.25 = 64
I am not sure which equation your teacher would want because that all depends on the teacher and if there are any further details on the question. So if somewhere on the question it said you have to use a variable you would use the equation with the variable.
Step-by-step explanation:
1. The question claims that the total of all of the pounds of rice and bean bas equals a total of 64 so that would be the answer to the equation.
2. You now need to make an equation that represents the situation by setting up your equation like this: 7 + 4 . X = 64
How to find X and have an equation with an already solved X.
1 We know that in total each bag has 64 pounds so that means we have to subtract 7 from 64. The difference is 57.
2. We now need to divide 57 by 4 because the rest of the bags have an identical amount of pounds so your answer should be 14.25.
3. Your equation should be set up like this: 7 + 4 . 14.25 = 64

Calculate 48 x 3/8 choose the numbers to complete the equation
Answer:
1. Choose: 3
2. Choose: 144
3. Choose: 18
Step-by-step explanation:
The first thing you do is multiply 48 * 3/8= 18. Then multiply 48 * 1/8= 6. Then divide both answers to get 3, so 48 * 1/8 * 3.
Then to find the second Choose option, you know that 48 * 1/8 * 3= 18; so 18 * 8= 144(to check your answer, divide 144/8 = 18).
Finally, to find the third Choose option, you divide the fraction 144/8 = 18.

If you add the digits in a two-digit number and multiply the sum by 7, you get the original number. If you reverse the digits in the two-digit
number, the new number is 18 more than the sum of its two digits. What is the original number?
A. 42
B. 24
C. 64
D. 46
Е. 36
The answer is A. 42
Solution:
Let x= ones digit, y=tens digit
1st condition (original number) : 7(x+y)=10y + x
2nd condition (new number by reversing the digits): 18+x+y=10x+y
simplifying:
1st condition: 6x=3y
2nd condition: x=2
substituting x=2 to 6x=3y
y=4

42

We start off by drawing out the triangle on a graph! Placing points (x ,y) at
(-3, 5), (-5, -2) and (2, -2). I've included a screenshot of how the triangle should look to help you out visually!
From there, to find the area we use the equation, area = [tex]\frac{1}{2}[/tex] b • h.
To find the base, we subtract: -5 - 2 = -7, meaning that the base equals 7.
And to find the height, we subtract: 5 - (-2) = 7, also meaning that the height equals 7 as well.
Plugging those two numbers in the equation for area, we get:
area = [tex]\frac{1}{2}[/tex] 7 • 7
area = [tex]\frac{1}{2}[/tex] 49
area = 24.5 or 24 1/2, in this case your answer should be B.
