X would equal -4 and for the point on a graph would be -4,0

<span>The best way to find the angular and linear coefficient is by assembling the reduced equation:
 
2x - y + 8 = 0
- y = - 2x - 8 .(- 1)
y = 2x + 8
 
The angular coefficient is the value that accompanies the X and the coefficient is the value that comes alone.
 
Angular Coefficient: 2
Linear Coefficient: 8
 
</span><span>If you want to find the values ​​X and Y, we have:

</span>2x - y + 8 = 0 
2(x - 8) = y 
<span>x - 8 = 2 </span>
<span>x = 2+8 </span>
x = 10 

2x - y + 8 = 0 
2*10 - y + 8 = 0
20 - y = - 8
- y = - 8 - 20
- y = - 28 .(-1)
y = 28

Confirm that the solution is correct:
2x - y + 8 = 0 
2*(10) - 28 + 8 = 0
20 - 28 = -8
- 8 = - 8 (TRUE)

Which expression is equivalent to the quantity five raised to the negative second power times three raised to the fifth power en
serg [7]

The equivalent expression is 5^(4) * 3^(-10)

<h3>How to determine the equivalent expression?</h3>

The statement is given as:

five raised to the negative second power times three raised to the fifth power end quantity all raised to the negative second power

Rewrite properly as:

(5^-2 * 3^5)^-2

Expand the expression by multiplying the exponents

So, we have:

5^(-2 -2) * 3^(5 *-2)

Evaluate the products

5^(4) * 3^(-10)

Hence, the equivalent expression is 5^(4) * 3^(-10)

How many triangles can be made if one angle is 95° and another angle is obtuse?
Elenna [48]
D. None. Say the obtuse angle is 100 degrees. Since the sum of all angles in a triangle cannot be bigger than 180, it's not possible because 195 (100+95) is greater than 180 degrees. Hope this helps.

Good x sold for $40 in 1945. the Cpi in 1945 was 18.0 and the cpi in 1999 was 166.6. what was the price of good x in 1999 dollar
andrey2020 [161]

Answer:

the price of good x in 1999 dollars is 370.89 dollars

Step-by-step explanation:

Given that good x sold for $40 in 1945. the Cpi in 1945 was 18.0 and the cpi in 1999 was 166.6.

We have cpi and sale price have direct variation

In other words S = kC where C = CPi and S = sales price

In 1945, 40 = 18k or K = 20/9

Using this we can say

Sales price in 1999 would be k (166.6)

=\frac{20}{9} (166.6)\\= 370.89

the price of good x in 1999 dollars is 370.89 dollars

Suppose a lab needs to make 400 liters of a 39% acid solution, but the only solutions available to the lab are 20% acid and 50%
Alekssandra [29.7K]
Mixture problem.
Ratio of 20% : 50% acids
=50-39 : 39-20
=11:19
total volume
=400L
vol. of 20% acid=400*(11/(11+19)=400*(11/30)=146.667 L
vol. of 50% acid=400*(19/(11+19)=253.333 L

Alternatively, use c=volume of 20%, d=vol of 50%
then
0.2c+0.5d=400*0.39
Since c+d=400, we have
0.2c+0.5(400-c)=400*0.39=156
solve for c:
0.3c=44
c=146.667 and d=400-c=253.333  as before.
