Answer:

True

Step-by-step explanation:

If two lines are perpendicular, they form four right angles. When two lines are perpendicular, there are four angles formed at the point of intersection. If two lines intersect to form a linear pair of congruent angles, then the lines are perpendicular.

Given h(t)=-2(t+5)^2 find h(-8) 334 –14 45 445

Tems11 [23]

Answer:

h(-8) = -18

Step-by-step explanation:

It is given that,

h(t)=-2(t+5)^2 --------(1)

To find h(-8)

Substitute t = -8 in equation (1)

h(-8) = -2(-8 + 5)^2

h(-8) = -2(-3)^2

h(-8) = -2 x 9 = -18

therefore the value of h(-8) = -18

But there is no option with value h(-8) = -18

Margaret [11]

Answer:

- 5

Step-by-step explanation:

The opposite of 7c is - 7c, thus the sum is

7c - 5 + (- 7c)

= 7c - 5 - 7c ← collect like terms

= - 5

Of course! so basically for each value of x, for example -6, plug it into the equation. so for -6 do -2/3(-6)+7. hope this helps!

In quadrilateral DBCA, name the angles which are consecutive with angle D.

lisov135 [29]

Answer: The consecutive angles with angle D are B and A.

Explanation:

It is given that DBCA is a quadrilateral. Since it is a quadrilateral it means the have 4 vertices and 4 angles D, B,C,A.

The angles are formed in the order of the figure name. If the quadrilateral name is DBCA, So the order of the angles are D,B,C,A. It means the angle immediate after D is B, the angle immediate after B is C, the angle immediate after C is A and the angle immediate after A is D.

If the quadrilateral name is DBCA it means the sides are DB, BC, CA and AD as shown in the figure.

Consecutive angles of D means the angle immediate before and after the angle D.

In the figure there are some types of quadrilateral and from the figure we can easily noticed that the consecutive angles with angle D are B and A.
