Answer:

4) m: 1.25 b: 6 Equation: y= 1.25x + 6

5) m: 20 b: 10 Equation: y= 40x + 10

6) m: -2 b: 0 Equation: y= -2x + 0

7) m: 1/5 b: 1 Equation: y= 1/5x + 1

8) -8.7 = 1.3x + 0

I really hope this helps!

There are two spinners. The first spinner has three equal sectors labeled 1, 2, and 3. The second spinner has four equal sectors

zhuklara [117]

<h3>Answer: A) 1</h3>

=========================

Explanation:

Let's label each pair of outcomes as an ordered pair (x,y)

x = first spinner outcome

y = second spinner outcome

We have these 12 different possible combos

(1,3), (1,4), (1,5), (1,6)

(2,3), (2,4), (2,5), (2,6)

(3,3), (3,4), (3,5), (3,6)

Focus on the third column where y = 5 for each (x,y) pair. Of this column only (2,5) has x be an even number. The other results in that column have x be odd.

Basically (1,5) is the only possible outcome if we want the first spinner to lan on an even number, and the second spinner to land on 5.

Parallelogram R S T U is shown. Diagonals are drawn from point R to point T and from point U to point S and intersect at point V

stiv31 [10]

Answer:

Option C.

Step-by-step explanation:

Given information: RSTU is a parallelogram, Digonals RT and SU intersect each other at point V, UV=(x-3) and VS=(3x-13).

According to the properties of a parallelogram, the diagonals of a parallelogram bisect each other.

Using the properties of parallelogram we can say that point V divides the diagonal SU in two equal parts, UV and VS.

$VS=UV$

$3x-13=x-3$

Subtract x from both sides.

$2x-13=-3$

Add 13 on both sides.

$2x=10$

Divide both sides by 2.

$x=5$

Therefore, the correct option is C.

Q55.
UTA+ATS=UTS
x+18+120=12x+17
x+138=12x+17
12x-x=138-17
11x=121
x=121/11
x=11

mUTA=x+18
put the value of x
11+18
mUTA=29

Q57.
AQP+RQA=RQP
9x+2+75=1+28x
9x+77=1+28x
28x-9x=77-1
19x=76
x=76/19
x=4

mRQP=1+28x
put the value of x
1+28(4)
1+112
mRQP=113
