Answer:

\text{The equation is }\frac{14}{4}x+y=1.05

Step-by-step explanation:

Given that line JK passes through points J(–3, 11) and K(1, –3).

we have to find the equation of JK in standard form.

\text{The slope of line joining the points }(x_1,y_1)\text{ and }(x_2, y_2)\text{ is given by}

m=\frac{y_2-y_1}{x_2-x_1}

Line JK passes through points J(–3, 11) and K(1, –3).

m=\frac{-3-11}{1-(-3)}

m=\frac{-14}{4}

Put in slope intercept form

y=mx+b

11=\frac{-14}{4}(-3)+b

11\times \frac{4}{42}=b

b=1.05

The equation is

y=\frac{-14}{4}x+1.05

\frac{14}{4}x+y=1.05

which is required form.

Triangle QST  is similar to triangle PQR

We are given that measure of angle SRP is 90°

Q is the point of the hypotenuse SP

Segment QR is perpendicular to PS and T is a point outside the triangle on the left of s

We need to find which triangle is similar to triangle PQR

So,

Using Angle - Angle - Angle Criterion We can say that

m∠PQR = m∠SQR  (AAA similarity)

m∠SQR=m∠SQT (AAA similarity)

Where m∠Q =90°  in ΔQST and PQR

Therefore ΔQST is similar to ΔPQR

It said i need to simplify. how do i
horrorfan [7]

Answer:

The equation relating the volume of water, y to the volume of flour, x is therefore;

y = 1/3×x

The quantity of water per liter of flour = 1/3 liters

The quantity of flour per liter of water = 3 liters

Step-by-step explanation:

The given information from the graph are;

At 0 liters of water, the volume of flour = 0 liters of flour

At 1 liter of water, the volume of flour = 3 liters of flour

The relationship between the volume of water and flour is linear given s follows;

The equation for a linear relationship is y = m·x + c

m = The gradient or slope of the line, c = the y-intercept

In the graph the y-intercept = 0 therefore, c = 0

The slope, m is (change in y-coordinate)/(Change in x-coordinate)

∴ m = (1 - 0)/(3 - 0) = 1/3

The equation relating the volume of water, y to the volume of flour, x is therefore;

y = 1/3×x

Such that when the question asks, how many liter of water is used per liter of flour, we get;

y = 1/3× 1 = 1/3 liters

Similarly when the question asks, how many liter of flour is used per liter of water, we get;

1 = 1/3×x

x = 3 × 1 = 3 liters.
