2x=3y-1

1 answer:

7 0

If you put both equations in standard form, you see they are the same equation.
2x -3y = -1
The "system" will have an infinite number of solutions.

_____
You must subtract 3y from the first equation to get it to standard form.
You must factor 3 from the second equation to get it to standard form.

Maristella is constructing an isosceles triangle to use as a model in her Algebra class. The perimeter of her triangle is 24 cm.

Vlada [557]

Isolating s, the equation written in terms of s is:

$s = 12 - 0.5b$

-------------------------

The equation for the length of the third side, as stated in the problem,("Maristella uses the equation b = 24 – 2s to find b, the length of the triangle's third side") is:

$b = 24 - 2s$

To solve for the lengths of the congruent sides, we isolate s, thus:

$b = 24 - 2s$

$2s = 24 - b$

Inverse of multiplication is division, thus:

$s = \frac{24 - b}{2}$

Separating into two fractions:

$s = \frac{24}{2} - \frac{b}{2}$

Solving each fraction:

$s = 12 - 0.5b$

What is 70% of blank = 28

QveST [7]

Percent means parts out of 100
70%=70/100=7/10
7/10 of x=28
'of' means multiply
7/10 x=28
multiply both sides by 10/7 to get rid of fraciton
x=40

the number is 40

Find the linear function with the following properties. <br><br> f(0)=−9 Slope of f=−8

Ratling [72]

Answer:

f(x) = -8x - 9

Step-by-step explanation:

<h3>Given </h3>

<u>Function f, with </u>

f(0) = -9
Slope of f = -8

Linear function

<h3>Solution</h3>

<u>Slope-intercept formula</u>

f(x) = mx + b
f(0) = -9 means y-intercept b = -9, and the slope is m = - 8

<u>So the function is</u>

f(x) = -8x - 9
