Hi there.
The answer is (-2,7). The second choice.
Explanation:
We can use the graph method or the solving method.
For the graph method, find where both graphs intercept and that is x = - 2 y = 7.
But if you don't use the graph method. We can solve the equation.
[tex]y = 0.5x+ 8 \\ y = \frac{5}{10} x + 8 \\ y = \frac{1}{2} x + 8[/tex]
Convert the expressions in simplified form.
Then combine both equations.
[tex] \frac{1}{2}x + 8 = 5 - x[/tex]
Because there is the denominator. We get rid of it.
Multiply the whole equation by 2.
[tex] \frac{1}{2} x(2) + 8(2) = 5(2) - x(2) \\ x + 16 = 10 - 2x \\ 3x = 10 - 16 \\ 3x = - 6 \\ x = - 2[/tex]
Since it is the two variables linear equations, we need to find y-value too.
Substitute x = -2 in any given equations.
I will substitute x = -2 in y = 5-x
[tex]y = 5 - x \\ [/tex]
Substitute x = -2 in the equation.
[tex]y = 5 - ( - 2) \\ y = 5 + 2 \\ y = 7[/tex]
Thus, the answer is x = -2, y = 7
Or
(-2,7)

If the cost of electricity to produce magnesium by the electrolysis of molten magnesium chloride is $155 per ton of metal, what is the cost of the electricity necessary to produce 10 tons of aluminum?
Answers
Answer:
$1550
Step-by-step explanation:
Given the price of mgCl per ton of metal to be $155, that is;
1 ton of metal = $155
To find the cost of 10 ton of alumininum, we will say;
10 ton of aluminum = x
Equating both expressions;
1 ton of metal = $155
10 ton of aluminum = x (note that aluminum is a metal)
Cross multiply;
1 * x = 155 * 10
x = 1550
Hence 10 tons of aluminum will cost $1550

(2x+3)(x+5)
Explanation:
Numerator: a^2 - b^2 = (a+b)(a-b) in this case a = x and b = 5
Denominator: a times c (2 times 15 equals) 30, b is equal to 13... we must find numbers that goes equals both of these, we will use 10 and 3. 10 times 3 equals 30 and 10 plus 3 equals 13. Therefore we get 2x^2 + 10x +3x +15 which goes to 2x(x+5) + 3(x+5) which then goes to (2x+3) + (x+5)

if Santiago is 5 feet tall and 11 inches tall and Michael is 5 feet tall and 2 inches tall, what is their total height in centimeters rounded to the nearest centimeter? There are 2.54 centimeters in 1 inch
Answers
Answer:
337.82 cm
Step-by-step explanation:
Santiago is 5 feet tall and 11 inches tall and Michael is 5 feet tall and 2 inches tall.
We need to find total height in cm.
1 inch = 2.54 cm
1 feet = 30.48 cm
5 feet 11 inches = 5(30.48) + 11(2.54)
= 180.34 cm
5 feet 2 inches = 5(30.48) + 2(2.54)
= 157.48 cm
Total height = Santiago's height + Michael's height
= 180.34 cm + 157.48 cm
= 337.82 cm
Hence, their total height is 337.82 cm.

At a magazine, the ratio of
• artists to photographers is 3:2.
• photographers to writers is 1:3.
• writers to editors is 2:1.
There are 9 artists. How many
photographers, writers, and
editors does the magazine have?
Answers
Answer: 33
Artists : photographers = 3 : 2, and there are 9 artists, so there are 6 photographers. Then, the ratio of photographers to writers is 1 : 3, so there are 18 writers. Finally, there are half as many editors as writers, so there are 9 editors.
There are 6 + 18 + 9 = 33 photographers, writers and editors total.

Find the scope by counting
Answers
Answer:
-6
Step-by-step explanation:
to find slope by counting you just count rise over run
to get from (1,-4) to (0,2) you must go up 6 and back 1
6/-1 (negative cause you went back)
Answer:
Step-by-step explanation:
How is the slope (or gradient) usually found?
[tex]m = \frac{\Delta y}{\Delta x}[/tex]
In other words, this means that the slope is found by dividing the change in y by the change in x.
How many units change in regards to y? We can count! Let's start counting from the y-intercept (the red dot that on the y-axis). 2,1,0,-1,-2,-3,-4. We counted -6 since we went down.
Now let's count the change in x, if we start from the y-intercept once more, how many units do we have to move to get to the second red dot? Well that's 1! We only have to move one square to the right to get to the second red dot.
Let's plug this into the equation I stated at the start of this answer
[tex]m = \frac{-6}{1}[/tex]
And we know that [tex]\frac{-6}{1}[/tex] is just equal to -6.
Therefore, the slope of this line is -6!
