The equation would be y=-1/5x+2
The slope is always switched to make a line parallel to the first equation
First you have to subtract 3x and then divide everything by -4 to get y=3/4x-7
By looking at the graph, it seems Equation A and Equation C both intersect at (0, 8). So the first answer is correct.
Answer:
Step-by-step explanation:
Just multiply the sides. For example, the roses take 8x4=32 feet. if we want to know the area of Zinnias, we multiply the sides 8x12 and remove the roses, which would be 8x12-32=96-32=60 for the Zinnias.
For a)
The roses take 8x4
Zinnias take 8x12 - roses
Snapdragons take 16x12 - roses - zinnias
Petunias take 16x20 - snapdragons - zinnias- roses
b) The entire area of the garden is 20x16=320 square feet
The area of the Zinnias(including roses) is 8x12 = 96 square feet
To get the percent, we divide the smaller number by the bigger number and multiply by 100 or in practice 96/320x100=30%
c) Let's see the progression here. The width progresses in the first rectangle by four 8 to 12, then again by four 12, 16 and again by four 16 to 20, which means that the next rectangle would have a width of 20+4=24. Doing the sale analysis for the height, we get that the increase is with 4 feet at a time or the new rectangle would have a width of 24 and height of 20, which means a total area of 480 feet. We have to subtract all other rectangles or the new area would be 480 - (20x16) = 160 square feet
Answer:
34 goes in the blank.
Step-by-step explanation:
Triangle ABC is congruent to triangle TUV implies the following:
Angle A is congruent to angle T.
Angle B is congruent to angle U.
Angle C is congruent to angle V.
Side AB is congruent to side TU.
Side BC is congruent to side UV.
Side CA is congruent to side VT.
Note: Order tells you everything in a congruence statement.
Since side BC is congruent to UV, then the measure of side BC is equal to the measure of side UV.
8x+2=7x+6
Subtract 7x on both sides:
1x+2=6
x+2=6
Subtract 2 on both sides:
x=6-2
x=4
So if x=4, then the measure of side BC is 8x+2=8(4)+2=32+2=34.
So the measure of BC is 34 cm.
