Find the slope first: 4=x 2=y 1=x2 -7=y2
-7-2/1-4=-9/-3
So the slope is -9/-3
so far we have y=-9/-3x-b
then we replace
2=-9/-3(4)-b
2=-9/-3*4-b
2=12-b
12-2=10
10=b
So y=3x-10
The answer would be the median is ~62~
Hope this helps
Have a great day/night
We have that
3^y = 7
applying log both members
log(3^y)=log 7
y*log 3=log 7
y=log 7/log 3
using the <span>logarithmic graph of y=log x
</span><span>I graphically determine the values for x = 3 and x = 7
</span><span>
see the attached figure
for x=3
log 3=0.48
for x=7
log 7=0.85
therefore
</span>y=log 7/log 3-----> y=0.85/0.48-----> y=1.77
<span>
the answer isthe </span><span>
approximate value of y is 1.77</span>
Answer:
Sweater =400 grams
Hat =80 grams
Scarf =75 grams
Step-by-step explanation:
The amount of wool used to make a sweater, a hat and a scarf=555 grams
Let the amount of wool used to make a sweater be = x
The amount of wool for the sweater =x/5
The amount of wool used for the scarf=x/5 -5
Total amount of wool used = x+(x/5)+(x/5-5)
x+x/5 +x/5-5=555
Multiply all through by the LCM 5
5x+x+x-25=2775
7x=2800
x=400
Sweater =400 grams
Hat=400/5=80 grams
Scarf =400/5 -5=75 grams
The only two prime numbers that differ by 1 are 3 and 2 .
