Now,

b + 40° = 90° ( right angle )

or, b = 90° - 40°

◆ b = 50°

B) 50°

This is Right answer...

I hope it's help you...

3) x2+ y2 - x + 3y - 42 = 0<br> X+y=4

REY [17]

The solution is $(-1,5)$ and $(7,-3)$

Step-by-step explanation:

The expression is $x^{2} +y^{2} -x+3y-42=0$ and $x+y=4$

Using substitution method we can solve the expression.

Let us substitute $x=4-y$ in $x^{2} +y^{2} -x+3y-42=0$

$(4-y)^{2} +y^{2} -(4-y)+3y-42=0$

Expanding and simplifying the expression, we get,

$\begin{array}{r}{16-8 y+y^{2}+y^{2}-4+y+3 y-42=0} \\{2 y^{2}-4 y-30=0}\end{array}$

Let us use the quadratic equation formula to solve this equation,

$\begin{aligned}y &=\frac{4 \pm \sqrt{16-4(2)(-30)}}{2(2)} \\&=\frac{4 \pm \sqrt{16+240}}{4} \\&=\frac{4 \pm 16}{4} \\y &=1 \pm 4\end{aligned}$

Thus, $y=5$ and $y=-3$

Substituting y-values in the equation $x+y=4$ , we get the value of x.

For $y=5$ ⇒ $x=4-5=-1$

For $y=-3$ ⇒ $x=4+3=7$

Thus, the solution set is $(-1,5)$ and $(7,-3)$

3 pints because 12*4 is 48 and 48 divided by 8 is 6 so then there are 6 cups. 6 cups make 3 pints.

Answer: 0.1 or 1/10

Step-by-step explanation:

$\left(\frac{3}{4}-\frac{2}{3}\right)\cdot \:1\frac{1}{5}$

$1\frac{1}{5}=\frac{6}{5}$

$\left(\frac{3}{4}-\frac{2}{3}\right)\cdot \frac{6}{5}$

$\frac{3}{4}-\frac{2}{3}$ $=\frac{9}{12}-\frac{8}{12}$

$=\frac{1}{12}$

$\frac{6}{5}\cdot \frac{1}{12}$

Cross, cancel common factor

$\frac{1}{2}\cdot \frac{1}{5}$

$=\frac{1}{10}$

Is (4,3) a solution to 2x-y <4?

olga55 [171]

Sub the point into the inequality
2(4)-3<4
8-3<4
5<4
Therefore, no, it is not a solution because 5 is not less than 4
Hope this helps!
