Answer:

Solve for in the equation 3 (x- 0.27)= 1.35

Step-by-step explanation:

First you look at a diagram and notice that you are moving forward so you are multiplying the 3 pack of tubes by the 0.27 ounce of glue to get your answer of 1.35

Answer:

x intercept is $(-\frac{5}{3} , 0)$

y intercept is $(0,\frac{5}{2} )$

Step-by-step explanation:

1.) turn the equation into slope intercept form, so...

When $(3x+2y=5)$ then... $y=-\frac{3x}{2} +\frac{5}{2}$

2.)When finding the x-intercept, then plug y=0 and solve for x.

$(0)= -\frac{3x}{2} +\frac{5}{2} \\(\frac{2}{3}) -\frac{5}{2} =-\frac{3x}{2} (\frac{2}{3} )\\-\frac{5}{3} =x$

3.) When finding the y-intercept, plug x=0 and solve for x.

$y=-\frac{3(0)}{2} +\frac{5}{2}$

$y=\frac{5}{2}$

The equation for a parabola has the form y=ax2+bx+c, where a, b, and c are constants and a≠0. find an equation for the parabola

IRISSAK [1]

The equation of parabola is

$y= ax^2 + bx +c$

For point (-1,-9), equation of parabola is

$-9 = a(-1)^2 +b(-1)+c
\\
-9 = a -b+c$

For point (1,7), equation of parabola is

$7 = a(1)^2 + b(1)+c
\\
7 = a + b +c$

For point (-6,-14), equation of parabola is

$-14 = a(-6)^2 +b(-6)+c
\\
-14 = 36a -6b +c$

So we have three equations , which are

$a - b + c =-9,
\\
a + b + c = 7
\\
36a -6b+c = -14$

Subtracting first two equation will give

$-2b = -16
\\
b=8$

Subtracting second and third equation gives

$a+b+c-36a+6b-c = 7+14
\\
-35a +7b = 21
\\
-5a + b =3$

Substituting 8 for b, we will get

$-5a + 8 =3
\\
-5a = -5
\\
a =1$

back substituting 8 for b and 1 for a, we will get

$1+8+c = 7
\\
c = -2$

So we have

$a=1, b=8 and c=-2$

Therefore required equation is

$y= x^2 +8x-2$
