To find the x-intercept, set y=0 and solve for x.
To find the y-intercept, set x=0 and solve for y.
7x+6y=21
x-int: y=0
7x+6(0)=21
7x=21
x=3
y-int: x=0
7(0)+6y=21
6y=21
y=21/6 or 7/2

Answer:
- All four of the remaining faces will be 4 inches wide.
Step-by-step explanation:
A right rectangular prism with square base and top with sides of 4 in.
It has four sides of 4 in wide each and of equal height of unknown measure.
<u>Options:</u>
All four of the remaining faces will have a height of 4 inches.
- Incorrect, the height is unknown.
There is not enough information to tell what the other faces will look like.
- Incorrect, all the other faces are rectangular.
Two of the remaining faces will be 4 inches wide.
- Incorrect, all the faces are 4 in wide.
All four of the remaining faces will be 4 inches wide.
Answer:
7. x=3, 8. x=7, 9. x=15.
Step-by-step explanation:
7. If lines m and n are congruent, then angles DCF and CFE are congruent. 15x+3=18x-6. Solve for x. --> 15x+9=18x-->3x=9-->x=3
8.If line m is parallel to line n, then the corresponding angles are congruent. So, 20x+1=22x-13 Solve for x. 20x+14=22x-->14=2x-->x=7.
9. The supplementary angle of 110 is 70. Note that all of the inner angles of a triangle are equal to 180. Form an equation using the the values: (4x+8)+(2x+12)+70=180. Simplify; 6x+90=180. Solve for x: 6x+90=180-->6x=90-->x=15.
Hope this helps!
