We have two points so we can find the gradient using y1-y2/x1-x2
gradient = 21-27/2-8
= 1
we know the form for any linear equation is y = mx + c
we have m and a point so we can substitute in point (2,21) to find c
21 = 1 x 2 + c
c = 19
therefore, the equation is y = x + 19
Answer:
i think your question is missing something??
Step-by-step explanation:
3(4) + 6 = 7 (2(4)-3)
12 + 6 = 7 (8-3)
18 = 7 (5)
18 = 35?
Answer:
whats the question
Step-by-step explanation:
Answer:Only one triangle can be constructed
Step-by-step explanation:
According to the question sides given are 1m, 2m and 2m
For the possibility of a triangle the sum of the two sides must be greater
than the third side
We have 1+2>2
⇒3>2
Also 2+2>1
⇒4>1
So the possibility of a triangle is fulfilled
Only an isosceles triangle can be constructed
as two sides are equal

Step-by-step explanation:
Monday
1.) <em>1250 gallons of water for 1 ounce of Granular chlorine.</em>
<em></em>
2.) <em>w = 1250c</em>
Tuesday
9.5% of 50
0.095 × 50 = 4.75
<em>The fee costs $4.75</em>
Since the fee will be deducted from the selling price..
50 - 4.75 = 45.25
<em>Once he pays for the fee, he'll make $45.25.</em>

Wednesday
To get 1 cup of sugar, you multiply 4 to 1/4 meaning to find the proportional amount of flour used, you have to multiply 2/3 by 4
2/3 × 4 = 8/3
<em>She should use 2 ²/₃ cups of flour</em>
Since in the new recipe, we're multiplying everything by 4..
16 × 4 = 64
With this new recipe, she can make 64 cookies.
Thursday
4800 ÷ 6400 = 0.75
0.75 × 100 = 75
4800 is 75% of 6400
100 - 75 = 25
<em>So, the cost of health insurance for the family increased by 25%</em>
