The value B is 7. If we apply B=7 the answer is 17 for the expression 17×
Step-by-step explanation:
The given expression is 17×
Step:1
Form an equation from given data,
17×= 17..............................(1)
(∵ product equal to 17)
Step:2
Check for alternatives by apply the value of B in eqn (1)
Assume be value of B for check the equation
B=1
Equation becomes,
17× = 2.4286 ≠ 17
Take, B=2,
17× = 4.8571 ≠ 17
Take, B=3,
17× = 7.2857 ≠ 17
similarly,
B=7,
17× = 17 (∵ The product equals to 17)
Result:
So, the answer for B is 7.
Answer:
9x+5y=-45
Step-by-step explanation:
To write the equation of a line we must have a slope and a point. To find the slope we use the slope formula and substitute (x,y) points in it as shown below:
Now that we have the slope, plug in the slope and choose one point to plug into the point slope formula. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.
(y-0)=-9/5(x--5)
y=-9/5(x+5)
y=-9/5x-9
Now convert to standard form, Ax+By=C.
y=-9/5x-9
9/5x+y=-9
9x+5y=-45
