I need help i dont understand this

Nata [24]

Answer:

Step-by-step explanation:

Given the 2 equations

4x + 8y = 21 → (1)

y = - $\frac{1}{2}$ x + 3 → (2)

Substitute y = - $\frac{1}{2}$ x + 3 into (1)

4x + 8(- $\frac{1}{2}$ x + 3 ) = 21 ← distribute parenthesis on left side

4x - 4x + 24 = 21 ( subtract 24 from both sides )

0 = - 3 ← not possible

This indicates the system has no solutions

suppose a parabola has a vertex of (-4 7) and also passes through the point (-3,8). what is the equation of the parabola in vert

jasenka [17]

The equation would be y = (x+4)² + 7

Because adding 4 to 'x' creates a transformation 4 units left and adding 7 to the whole function moves the parabola up 7

Hope this helps!

What is the relation between the variables in the equation x^4/y=7?

makkiz [27]

Answer:

So, the relation between variables are

$y=\frac{x^4}{7}$

Step-by-step explanation:

We are given

$\frac{x^4}{y}=7$

Since, we have to find relation between variables

so, we can solve for y

$\frac{x^4}{y}=7$

Firstly, we will multiply both sides by y

$\frac{x^4}{y}\times y=7\times y$

we can simplify it

$x^4=7\times y$

we can isolate y

so, we can divide both sides by 7

so, we get

$y=\frac{x^4}{7}$

Help fast !!!! I need to get this done before I go to school ixl AA.1

Lorico [155]

Answer:

slope = - $\frac{7}{5}$

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 5, 0) and (x₂, y₂ ) = (0, - 7 ) ← 2 points on the line

m = $\frac{-7-0}{0-(-5)}$ = $\frac{-7}{0+5}$ = $\frac{-7}{5}$ = - $\frac{7}{5}$
