Find the slope of the line that passes through the points (4, 3) and
(2, 7).
Answer:
-2
Step-by-step explanation:
7-3/2-4=-2
use slope formula
The equation of line passes through the points (4, 3) and (2, 7) will be;
⇒ y = - 2x + 11
What is Equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (4, 3) and (2, 7)
Now,
Since, The equation of line passes through the points (4, 3) and (2, 7)
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (7 - 3) / (2 - 4)
m = 4 / -2
m = - 2
Thus, The equation of line with slope - 2 is,
⇒ y - 3 = - 2 (x - 4)
⇒ y - 3 = - 2x + 8
⇒ y = - 2x + 11
Therefore, The equation of line passes through the points (4, 3) and
(2, 7) will be;
⇒ y = - 2x + 11

Stacy wants to go on a vacation that will cost her at least $1540. She has $1825 saved but has
$65 deducted every week from her paycheck to pay for her insurance. At most, how many
weeks can she have these deductions made in order to afford her vacation
Answer:
4 weeks
Step-by-step explanation:
First,, we should subtract the vacation price from her savings to get the base. That is 1835-1540=295. Then we can do 295/65,, and then we get 4 7/13. So,, she can only afford 4 weeks of these deductions in order to have enough money for her vacation.

I need help with this algebra question can someone explain the steps on how you solve it ?
Answer:
27
Step-by-step explanation:
(5+√2)²
you distribute the ² in the ()
so 5²+√2²
5²=25
√2²=2 because the √ and ² cancel each other out and you get 2
so now you have
25+2
which equals
27
Given expression:
(5 + [tex]\sqrt{2}[/tex])²
Now let us solve this problem by simplifying it;
(5 + [tex]\sqrt{2}[/tex])²:
the power implies the expression in the bracket should be repeated twice:
= (5 + [tex]\sqrt{2}[/tex]) (5 + [tex]\sqrt{2}[/tex])
Then expand the bracket by distribution;
= (5 x 5) + 5([tex]\sqrt{2}[/tex]) + 5([tex]\sqrt{2}[/tex]) + 2
= 25 + 10[tex]\sqrt{2}[/tex] + 2
= 27 + 10[tex]\sqrt{2}[/tex]

Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
These type of problems could be a little tricky so I'll explain this one as I go.
So the first step I would do is to multiply the 8 in both sides so you end up with...[tex]x+11=-24[/tex]
After that it should be easier and you'll go at it normally by subtracting the 11 in both sides and that should leave you with the answer of [tex]x=-35[/tex]

A local farm has a 0.75 acre field that was planted with 26,100 corn plants. one acre is equivalent to 43,500 square feet.
Assuming the same planting density, how many corn plants could they plant on a field with an area of 80,000 square feet?
The options are:
A. 34,800
B. 48,000
C. 60,000
D. 64,000
E. 100,000
(Please answer this as fast as possible)
Answer:
D
Step-by-step explanation:
So first what you want to do is find how many acres you're working with. Since you know that one acre is 43,500 square feet, you can find the number of acres you're working with by dividing 80,000 theoretical square feet by your given conversion:
80,000/43,500 is 1.83908045977
After this what you want to do is divide the theoretical acres by the conversion that was given to you in the problem:
1.83908045977/.075 is 2.45210727969
Now that you have this number, you would multiply the number of corn plants that you have in order to get the theoretical number of plants that you could plant on an area of that theoretical size of 80,000 square feet:
2.45210727969 times 26,100 is 64,000 even.
The number of corn plants that could be planted on 80,000 square feet is : 64000.
What is an acre?An acre is a unit for expressing the area of big shapes and objects like fields, farm lands.
Analysis:
If 1 acre is equivalent to 43500square feet, then 0.75 acre would be
0.75 x 43500 = 32625 square feet.
If 325625 square feet produce 26,100 corn plants , then 80,000 square feet would produce : [tex]\frac{80000 x 26100}{32625}[/tex] = 64000 corn plants.

Shelia's total amount of withholding is the sum of all the taxes paid.
Shelia's total amount of withholding = 31 + 7.25 + 44.05 + 15.85 = $98.15
Net pay is the gross pay less the total withholding.
$500 - $98.15 = $401.85.

Answer:
Joy will need to use 9 cups of strawberries for 6 cups of blueberries.
Step-by-step explanation:
Given,
Cups of blueberries used for 3 cups of strawberry = 2
Ratio of cups of blueberry to strawberry = 2:3
Joy wants to use 6 cups of blueberries.
Let,
x be the cups of strawberry for 6 cups of blueberries.
Ratio of cups of blueberries to strawberries = 6:x
Using proportion;
Ratio of cups of blueberry to strawberry :: Ratio of cups of blueberries to strawberries

Tell whether the given order pairs are solutions of the inequality.
y ≥ - 2x + 4 ; (0,4) (-1,8)
Answer:
both
Step-by-step explanation:
hi! let's plug in the ordered pairs into the equation. the x-coordinate is substituted for x in the equation, while the y-coordinate is substituted for y.
y≥-2x+4
(0,4)
4≥-2(0)+4
4≥0+4
4≥4
this is correct since 4 is equal to 4.
(-1,8)
8≥-2(-1)+4
8≥2+4
8≥6
this is also correct since 6 is less than 8.
therefore, both ordered pairs are solutions of the inequality.
