Answer:
x = 1/2
y = 4
Step-by-step explanation:
4x - y = -2 --------------------(I)
2x + 3y = 13 --------------------(II)
Multiply equation (I) by 3 and then add
(I)*3 12x - 3y = -6
(II) <u> 2x + 3y = 13 </u> {Now add and so y will be eliminated}
14x = 7
x = 7/14
x = 1/2
Plugin x = 1/2 in equation (I)
2 - y = -2
-y = -2 - 2
-y = -4
y = 4
7+9=16 you can use that cause that is the opposite equation
Y=2x+5
4x-2y=-10
4x-2(2x+5)=-10
4x-4x-10=-10
-10=-10
Answer:
2nd option: (0.5, 7), maximum; (2, 1) point of inflection; (3.5, -5), minimum.
Step-by-step explanation:
The maximum point, or a point of the graph with the highest y-value, is at
(0.5, 7).
The minimum point, or a point of the graph with the lowest y-value, is at
(3.5, -5).
The point of inflection is where the graph begins to change direction. This is at (2, 1).
Therefore, the 2nd option is correct.
Answer:
18.8 feet
Step-by-step explanation:
\tan M = \frac{\text{opposite}}{\text{adjacent}}=\frac{x}{5.4}
tanM=
adjacent
opposite
=
5.4
x
\tan 74=\frac{x}{5.4}
tan74=

x
5.4\tan 74=x
5.4tan74=x
Cross multiply.
x=18.832\approx \mathbf{18.8}\text{ feet}
x=18.832≈18.8 feet
Type into calculator and roundto the nearest tenth of a foot.
