Answer:
<em>(7, 11)</em>
Step-by-step explanation:
y = 2x - 3 .... (1)
x + y = 18 .... (2)
(1) ----> (2)
x + 2x - 3 = 18 ⇒ <u><em>x = 7</em></u>
y = 2(7) - 3 ⇒ <u><em>y = 11</em></u>
<em>(7, 11)</em>
Answer:
Dec 10
Step-by-step explanation:
0.25 liter = 250 ml
4 ml * 3 = 12 ml
250/12 = 20.83 days
Nov 20 - Nov 30: 11 days
Dec 1 - Dec 9: 9 days
On December 9, she can still take her 3 doses.
By December 9, she will have taken 12 ml per day for 20 days for a total of 240 ml. She has 10 ml left for Dec 10th.
On Dec 10, she will take 2 doses of 4 ml and 1 dose of 2 ml, and she will finish the medicine.
Multiply 2nd equation by 3 and add to first
9x-3y=-2
<u>-9x+3y=-9 +</u>
0x+0y=-7
0=-7
false
no solution
these lines aer paraalell so no solution
The given statement is proved by side-angle-side (SAS) theorem.
Yes, if two sides and the included angle of one triangle are congruent to the corresponding parts of another triangle the triangles are congruent.
The statement is proved by SAS theorem
<u>Side-Angle-Side (SAS) theorem: </u>
The triangles are congruent if two sides and the included angle of one triangle are equivalent to two sides and the included angle of another triangle.
Hence, The given statement is proved by side-angle-side (SAS) theorem.

Answer:
y = 3x + 5
Step-by-step explanation:
Okay, so first we do the equation for rise over run which is y2 - y1/ x2 - x1
so plug the numbers 11 - 17/ 4 - 2 getting the slope -3, now since we found the slope we need to find the intercept form, what you have to do now is plug in a coordinate from the x value and y value one of the pairs essentially so,
y = 3x + b, I chose your first pair
11 = 3 x 2 + b
equals to,
11 = 6 + b
now we want b, by itself.
5 = b
so the total intercept form answer is
y = 3x + 5
I will check over it,
11 = 3 x 2 + 5
11 = 11
I hope this helped!
