Answer:

x=-1 , y=-2

Step-by-step explanation:

Replace y in the first equation with x-1.

So, we have -4x+3(x-1)=-2

Multiply brackets with 3: -4x+3x-3=-2

-4x+3x=-2+3 (-3 becomes +3 after it changes sides)

-x=1 /*(-1)

x=-1

After we have x we include it in y=x-1

y=-1-1

y=-2

Answer:

a. 450 b. 10078.9097

Step-by-step explanation:

a. go with the formula W=FD

F= force

W= work done

D= distance

b. go with the formula F=mgcos(x)

M= mass

G= gravity constant (9.8)

then get to the normal formula of W=FD after getting the Force

Use a table of function values to approximate an x-value in which the exponential function exceeds the polynomial function. In y

bekas [8.4K]

F(x) = 2^x; h(x) = x^3 + x + 8

Table

x f(x) = 2^x    h(x) = x^3 + x + 8

0 2^0 = 1 0 + 0 + 8 = 8

1 2^1 = 2    1^3 + 1 + 8 = 10

2 2^2 = 4     2^3 + 2 + 8 = 8 + 2 + 8 = 18

3 2^3 = 8       3^3 + 3 + 8 = 27 + 3 + 8 = 38

4    2^2 = 16    4^3 + 4 + 8 = 76

10    2^10 = 1024 10^3 +10 + 8 = 1018

9    2^9 =   512 9^3 + 9 + 8 = 729 + 9 + 8 = 746

Answer: an approximate value of 10

According to this diagram what is tan 62

kicyunya [14]

The figure is not attached. So, I have attached it from the link- brainly.com/question/4198293

Answer:

$\tan(62)=1.875$

Step-by-step explanation:

Label the triangle ABC as shown below.

Given:

AB = 8, BC = 15, AC = 17, m∠ABC = 90°, m∠ACB = 28°, m∠BAC = 62°

The tangent of a given angle is given as the ratio of the opposite side and the adjacent side. The opposite side is the side opposite to the angle. The adjacent side is the other leg of the right angled triangle.

Here, the opposite side to angle A is BC and adjacent side is AB.

Therefore, the tan ratio of angle A is given as:

$\tan A=\frac{BC}{AB}\\\tan (62)=\frac{15}{8}=1.875$
