Answer:
Option A) multiply the top equation by 2 and the bottom equation by -3
Option D) To cancel the y's, multiply the top equation by -2.5.
Step-by-step explanation:
We are given the following equations in the question:
![3x+2y=17\\2x+5y=26](https://tex.z-dn.net/?f=3x%2B2y%3D17%5C%5C2x%2B5y%3D26)
We have to eliminate x from the equation in order to solve the equation.
Option A) multiply the top equation by 2 and the bottom equation by -3
![(3x+2y=17)\times 2\\ (2x+5y=26)\times -3\\\Rightarrow 6x + 4y = 34\\-6x-15y=-78\\\text{Adding equations we get}\\-11y = -44\\y = 4](https://tex.z-dn.net/?f=%283x%2B2y%3D17%29%5Ctimes%202%5C%5C%20%282x%2B5y%3D26%29%5Ctimes%20-3%5C%5C%5CRightarrow%206x%20%2B%204y%20%3D%2034%5C%5C-6x-15y%3D-78%5C%5C%5Ctext%7BAdding%20equations%20we%20get%7D%5C%5C-11y%20%3D%20-44%5C%5Cy%20%3D%204)
We have to eliminate y from the equation in order to solve the equation.
Option D) To cancel the y's, multiply the top equation by -2.5.
![(3x+2y=17)\times -2.5\\ (2x+5y=26)\times 1\\\Rightarrow -7.5x -5y = -42.5\\2x+5y=26\\\text{Adding equations we get}\\-5.5x = -16.5\\x = 3](https://tex.z-dn.net/?f=%283x%2B2y%3D17%29%5Ctimes%20-2.5%5C%5C%20%282x%2B5y%3D26%29%5Ctimes%201%5C%5C%5CRightarrow%20-7.5x%20-5y%20%3D%20-42.5%5C%5C2x%2B5y%3D26%5C%5C%5Ctext%7BAdding%20equations%20we%20get%7D%5C%5C-5.5x%20%3D%20-16.5%5C%5Cx%20%3D%203)
Answer:
968
Step-by-step explanation:
Rectangular Prism: 11*11*5 = 605
Square Pyramid: 11*11 * 9 over 3 = 363
363+605= 968
Answer:
undefined
Step-by-step explanation:
so you can just pick 2 points. use -3,0, and 2,0. so to get from -3 to 2(becusse slope is change of y over change of x) you add 5. to get from 0 to 0, you would add zero. so, 5/0=undefined. I'm not quite sure why thered 3,4. in that case it may just not be a function
Answer:
![\huge\boxed{slope=-\dfrac{3}{2}}](https://tex.z-dn.net/?f=%5Chuge%5Cboxed%7Bslope%3D-%5Cdfrac%7B3%7D%7B2%7D%7D)
Step-by-step explanation:
The formula of a slope:
![m=\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
We have two points (-6, -8) and (-14, 4).
Substitute
![x_1=-6,\ y_1=-8,\ x_2=-14,\ y_2=4](https://tex.z-dn.net/?f=x_1%3D-6%2C%5C%20y_1%3D-8%2C%5C%20x_2%3D-14%2C%5C%20y_2%3D4)
![m=\dfrac{4-(-8)}{-14-(-6)}=\dfrac{4+8}{-14+6}=\dfrac{12}{-8}=-\dfrac{12:4}{8:2}=-\dfrac{3}{2}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B4-%28-8%29%7D%7B-14-%28-6%29%7D%3D%5Cdfrac%7B4%2B8%7D%7B-14%2B6%7D%3D%5Cdfrac%7B12%7D%7B-8%7D%3D-%5Cdfrac%7B12%3A4%7D%7B8%3A2%7D%3D-%5Cdfrac%7B3%7D%7B2%7D)
