Answer:
i) y = 25 + 5x. ii) $85
Step-by-step explanation:
ii) y = 25 + 5 (12)
y = 25 + 60
y = 85
Answer:
y = -47
Step-by-step explanation:
To find the midpoint of two points, add them together and divide by 2
(y+33)/2 = -7
To find y, multiply each side by 2
(y+33)/2 *2 = -7*2
y+33 = -14
Subtract 33 from each side
y+33-33 = -14-33
y = -47
Answer:
x = 10/7 or x = -10/7
Step-by-step explanation:
By using the completing the squares method, we have to divide the coefficient of the x term by 2, square it and add to both sides
From what we have here, the coefficient of the x term is 0
Thus, we have it that;
0 = 100 - 49x^2
We can proceed to use the difference of two squares here;
Whereby;
a^2 - b^2 = (a-b)(a + b)
0 = (10-7x)(10+7x)
10 - 7x = 0 or 10 + 7x = 0
7x = 10 or 7x = -10
x = 10/7 or x = -10/7
Well i think it 120 your welcome
Answer:
5. 3/5-2/5=1/5; answer is 1/5
6.7/10-3/10=4/10; answer is 2/5(simplify)
7.5/6-4/6=1/6; answer is 1/6
8.3/4-2/4=1/4; answer is 1/4
Step-by-step explanation:
Explanation is above, when subtracting fractions remember that the denominator must be the same and you can subtract the numerator.
Hope this helps!
