Solve for x and show all work thanks:)
VladimirAG [237]

Answer:

x = -6

Step-by-step explanation:

The triangle in the picture is an isoceles triangle in which the measure of top vertex angle is given and one of the base angles is also given.

According to angle sum property of triangle , sum of measure of all the angles of traingle is 180°. Also, in isosceles triangle , the base angles are always equal to each other .

So,

34 + (x + 79) + (x + 79) = 180

=  > 2x + 158 + 34 = 180

=  > 2x +192 = 180

=  > 2x = 18 0 - 192 =  - 12

=  > x = \frac{12}{ - 2}  =  - 6

Y = -4x + 3<br> 8x + 2y = 8<br> Solve by using elimination.
ValentinkaMS [17]

Answer:

The equations are not compatible

Step-by-step explanation:

y = -4x + 3

8x + 2y = 8

substitute for y:

8x + 2(-4x + 3) = 8

simplify:

8x - 8x + 6 = 8

6 ≠ 8

Chloe notices that segment ST and segment VW are congruent in the image below.
IgorLugansk [536]
The SAS similarlity theorem is the type of similarlity that show that two triandles are similar by showing that two of the sides are similar with the angle between the two sides also similar.

Thus, given that <span>segment ST and segment VW are congruent, and also from the image it can be seen that angle S is congruent to angle V.

Thus, to show that </span>ΔSTU ≅ ΔVWX, we have to show that <span>US≅XV.

There</span>fore, the <span>step that could help her determine if ΔSTU ≅ ΔVWX by SAS is<span> US≅XV</span></span>

For how many integer values of n will the value of the expression 4n + 7 be an integer greater than 1 and less than 200?
Morgarella [4.7K]

Answer:

48

Step-by-step explanation:

We are asked that the value of (4n + 7) will be an integer > 1 and < 200, for how many integer values of n.

So, equating (4n + 7) with 200 we can get the value.

4n + 7 = 200

⇒ 4n = 193

⇒ n = 48.25

Hence, the value of n will be the largest integer less than 48.25.

Therefore, the number of integer values of n will be 48. (Answer)
