3/2y-3+5/3 z when y =6 and z= 3

Maksim231197 [3]

Answer:

Step-by-step explanation:

Plug in the value of y & z in the expression

$\frac{3}{2}y-3+\frac{5}{3}z=\frac{3}{2}*6-3+\frac{5}{3}*3\\\\\\=3*2 - 3 + 5 *1\\\\\\= 6 - 3 + 5\\\\\\= 3 + 5\\\\\\= 8$

Write an equation in slope intercept form given two points: (3,1),(0,10)

qaws [65]

Answer:

y = - 3x + 10

Step-by-step explanation:

We have to write an equation of a straight line in slope-intercept form that passes through the points (3,1) and (0,10).

Now, the equation of the straight line (using two points form) will be

$\frac{y - 1}{ 1 - 10} = \frac{x - 3}{3 - 0}$

⇒ y - 1 = - 3(x - 3)

⇒ y - 1 = 9 - 3x

⇒ y = - 3x + 10 (Answer)

{Since the slope-intercept form of a straight line equation is y = mx + c}

We know the equation of a straight line when any two points on the straight line ( $x_{1},y_{1}$ ), ( $x_{2},y_{2}$ ) are known, will be

$\frac{y - y_{1} }{y_{1} - y_{2}} = \frac{x - x_{1} }{x_{1} - x_{2}}$

13. Higher Order Thinking Eve and Gerard

ella [17]

Answer:

Gerard's blue section is larger.

Step-by-step explanation:

Eve divided her half into 6 equal sections and painted one section blue.

So, the blue-painted part will be of size $(\frac{1}{2} \times \frac{1}{6}) = \frac{1}{12}$ part of the whole poster.

Again, Gerard divided her half into 5 equal sections and painted one section blue.

So, the blue-painted part will be of size $(\frac{1}{2} \times \frac{1}{5}) = \frac{1}{10}$ part of the whole poster.

Now, since 12 > 10, so, $\frac{1}{12} < \frac{1}{10}$

Therefore, Gerard's blue section is larger. (Answer)

Plot the vertex and the axis of symmetry of this function on the provided graph.

tia_tia [17]

Answer:

(-2,-6)

-2

Step-by-step explanation:

To get the vertex take the number that's in the parathenses with the x and flip it's sign (in this case to a negative) which means we have

-2

this is the x coordinate of the vertex.

Next take the number that's being subtracted (or added) on the outside and leave that as is (-6)

This is the y coordinate

which means we have (-2,-6)

the axis of symmetry is just the x coordinate of the graph

which is -2
