Answer:

y = -3x + 4

Step-by-step explanation: Substitute the numbers in for x & y to see which one is the answer.

(-1, 7):

y = -3x + 4

7 = -3(-1) + 4

7 = 3 + 4

7 = 7

TRUE


(2, -2):

y = -3x + 4

-2 = -3(2) + 4

-2 = -6 + 4

-2 = -2

TRUE


(7, -17):

y = -3x + 4

-17 = -3(7) + 4

-17 = -21 + 4

-17 = -17

TRUE


(10, -26):

y = -3x + 4

-26 = -3(10) + 4

-26 = -30 + 4

-26 = -26

TRUE


Hope this helps you!!! :)

In the circle below, suppose m VUX = 152° and mZUVW = 77º. Find the following.
bezimeni [28]

Given:

In the circle, m(\overarc{VUX})=152^\circ and m(\angle MUV)=77^\circ.

To find:

The following measures:

(a) m\angle VUX

(b) m\angle UXW

Solution:

According to the central angle theorem, the central angle is always twice of the subtended angle intercepted on the same same arc.

m(VUX)=2\times m\angle VWX

152^\circ=2\times m\angle VWX

\dfrac{152^\circ}{2}=m\angle VWX

76^\circ=m\angle VWX

In a cyclic quadrilateral, the opposite angles are supplementary angles.

UVWX is a cyclic quadrilateral. So,

m\angle VUX+m\angle VWX=180^\circ          [Opposite angles of a cyclic quadrilateral]

m\angle VUX+76^\circ=180^\circ

m\angle VUX=180^\circ-76^\circ

m\angle VUX=104^\circ

Now,

m\angle UXW+m\angle UVW=180^\circ          [Opposite angles of a cyclic quadrilateral]

m\angle UXW+77^\circ =180^\circ

m\angle UXW=180^\circ-77^\circ

m\angle UXW=103^\circ

Therefore, m\angle VUX=104^\circ  and m\angle UXW=103^\circ .

Algebra 1 -5c+d=2c find for c
beks73 [17]

Answer:

d/7 = c

Step-by-step explanation:

-5c+d=2c

Add 5c to each side

-5c+5c+d=2c+5c

d = 7c

Divide each side by 7

d/7 = 7c/7

d/7 = c
