Find the slope...........
Answers
Point A: (3, -1)
Point B: (1, 2)
Then we will use the slope formula to work out the slope:
y₂ - y₁ / x₂ - x₁
Substitute in our points:
2 - (-1) / 1 - 3
Then we work out the expression (remember a negative and a negative make a positive!):
3 / -2
Then we check if we can simplify this fraction, which in this case we cannot.
Therefore the slope of that line would be:
3 / -2

Could someone please find the rate and y-intercept for these two points? (2,2) and (3,4) the help would be greatly appreciated!!
Answers
so a formula most commonly used is (y^1-y^2)/(x^1-x^2)
m= (y^1-y^2)/(x^1-x^2)
=m=(4-2)/(3-2)
=m=2/1
2/1 can also be expressed as just 2 since anything divided by 1 is just itself
Now use the formula y=mx+b to find the y intercept
use either of your two given point to susitute y and x
y=mx+b
Substitute your values
=(4)=(2)(3)+b
Calculate
=4=6+b
Subtract both sides by 6
=-2=b
Therefore the rate of change is 2/1 and the y-intercept is -2

Assume that the cheetah travels an average of 40 mph to go from its resting place to a rock near a river. On the return trip to its resting place, the cheetah travels an average of 70 mph. If the cheetah traveled for 15 minutes, how many minutes did the return trip take to the nearest minute and second?
Set up the table as follows. Label the rows “To the River” and “From the River.” Label the columns “Distance,” “Rate,” and “Time (in Hours).” Let t represent the unknown quantity in the problem. Fill in the table.
Answers
Answer:
9.55 minutes
Step-by-step explanation:
x hours to go to the river
0.25-x hours to come back, since 15 minutes is 0.25 hr.
to the river 40 mph * x hours =40x miles
from the river 70 mph (0.25-x) hours=17.5-70x
those two are equal
40x=17.5-70x
110x=17.5
x=17.5/110=0.159 hours
9.55 minutes

Each triangle weighs 2.5 pounds, each circle weighs 3 pounds and x represents the weight of each square, what is the weight of the square?
Answers
Answer:
0.25 pounds
Step-by-step explanation:
You set up an equation with the given information:
4x+2(2.5)+2(3)=2x+1(2.5)+3(3)Multiply: 4x+5+6=2x+2.5+9Add: 4x+11=2x+11.5Subtract: 4x=2x+0.5Subract: 2x=0.5Divide: x=0.25Now check your work:
4(0.25)+2(2.5)+2(3)=2(0.25)+1(2.5)+3(3)Multiply: 1+5+6=0.5+2.5+9Add: 12=120.25 pounds

5x + 2 = 3x + 4(2x - 1) please solve step by step
Answers
Answer:
x=1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5x+2=3x+4(2x−1)
5x+2=3x+(4)(2x)+(4)(−1)(Distribute)
5x+2=3x+8x+−4
5x+2=(3x+8x)+(−4)(Combine Like Terms)
5x+2=11x+−4
5x+2=11x−4
Step 2: Subtract 11x from both sides.
5x+2−11x=11x−4−11x
−6x+2=−4
Step 3: Subtract 2 from both sides.
−6x+2−2=−4−2
−6x=−6
Step 4: Divide both sides by -6.

x - 9 = 17
x + 12 = 20
2x = 16
Answers
X-9=17 is x=26
X+12=20 is x=8
2x=16 is 8
So its the second one
8/4=2
8-9=-1
8+12=20
2(8)=16
The second one isn’t correct because 8-9 is not 17, it is -1.
