Answer:

Well in order to find the equation you are looking for you first must find the slope of the line. Since it gives you two points at (-4, 1) and at (0, 4), use these points to find the slope.

y = (3/4)x + 4 is the answer

Determine whether is a right triangle for the given vertices. Explain. Q(7, –10), R(–3, 0), S(9, –8)

andriy [413]

Answer:

Yes, It is a right triangle for the given vertices.

Step-by-step explanation:

Given:

Q(7, –10),

R(–3, 0),

S(9, –8)

To Find:

determine whether is a rig ht triangle for the given vertices = ?

Solution:

QR= $\sqrt{(-3-7)^2+(0-(-10))^2}$

QR= $\sqrt{(-10)^2+(10)^2}$

QR= $\sqrt{100+100}$

QR= $\sqrt{200}$ --------------------------(1)

QR=14.142136

RS= $\sqrt{(9-(-3))^2+(-8-0)^2}$

RS= $\sqrt{(12)^2+(-8)^2}$

RS= $\sqrt{144+64}$

RS= $\sqrt{208}$ ---------------------------(2)

RS=14.422205

QS= $\sqrt{(7-9)^2+(-10-(-8))^2}$

QS= $\sqrt{(-2)^2+(-2)^2}$

QS= $\sqrt{4+4}$

QS= $\sqrt{8}$ -------------------------------------(3)

QS=2.828427

According to Pythagorean Theorem,

$RS^2 = QR^ +QS^2$

Substituting the values,

$(\sqrt{208})^2 = (\sqrt{200})^2 +(\sqrt{8})^2$

$208 = 200 +8$

208 = 208

Pythagorean theorem is satisfied. Hence it is a right triangle.

Glenn bought 3 pounds of tomatoes. He used 5/8 of them to make sauce.

n200080 [17]

Question Continuation:

Glenn bought 3 pounds of tomatoes. He used 5/8 of them to make sauce.

Make an equation that shows the number of pounds of tomatoes Glenn used for the sauce.

Answer:

$y = \frac{15}{8}\ lb$

Step-by-step explanation:

Given

Weight of Tomato = 3 lb

Used Proportion = 5/8

Required

Determine the portion used

To solve this we simply multiply the used proportion by the weight of the tomato bought

Represent the used portion with y.

So:

$y = Weight * Used\ Proportion$

$y = 3\ lb * \frac{5}{8}$

$y = \frac{15}{8}\ lb$

Solution set of 5/11x+1/3=3/7-6/11x+3/7

kirill115 [55]

$\frac{5}{11x} + \frac{1}{3} = \frac{3}{7} - \frac{6}{11x} + \frac{3}{7} \\ \frac{11}{11x} = \frac{6}{7} - \frac{1}{3} \\ \frac{1}{x} = \frac{11}{21} \\ x = \frac{21}{11} = 1 \frac{10}{11}$
