Find the equation for intercept x 4 and y -7​

Mathematics
1 answer:
nadezda [96]3 years ago
8 0

Answer:

y = \frac{-7x}{4} - 14

Step-by-step explanation:

The equation used to find the equation for a line with two intercepts is called point slope form. y - y_{1} = m(x - x_{1}) , where y_{1} and x_{1} are the intercept points and m is the slope.

However, we need the slope to use this formula.

Use m = \frac{y_{1} - y_{2} }{x_{1} - x_{2}}

m = \frac{y_{1} - y_{2} }{x_{1} - x_{2}}

m = \frac{((0) - (7))}{((4) - (0))}

m = \frac{-7}{4}

y - y_{1} = m(x - x_{1})

y - ( -7 ) = m ( x - ( 4 ) )

y - ( -7 ) = -7/4 ( x - ( 4 ) )

y + 7 = -7/4 ( x + 4 )

y + 7 = \frac{-7(x+4)}{4}

y + 7 = \frac{-7x-28}{4}

y + 7 = \frac{-7x}{4} - 7

y + 7 = \frac{-7x}{4} - 7 - 7

y = \frac{-7x}{4} - 14

jasenka [17]

let apple juice = x

 milk = 2x

 fruit punch = 3x

3x + 2x + x = 660

6x = 660

x = 660/6

x = 110 apple juices

2*110 = 220 milks

3*110 = 330 fruit punches

ASAP!! Please help me. I will not accept nonsense answers, but will mark as BRAINLIEST if you answer is correctly with solutions
aliina [53]

Answer:  B. H(t) = -6.9(t - 2.3)² + 112

<u>Step-by-step explanation:</u>

The vertex form of a quadratic equation is: y = a(x - h)² + k

where (h, k) is the vertex   ⇒    k is the maximum height

the distance traveled is when y = 0     ⇒    x=\sqrt{\dfrac{-k}{a}}+h

Given: H(t) = -7.1(t - 2.3)² + 98

maximum height (k) = 98 feet

distance traveled (x) = \sqrt{\dfrac{-98}{-7.1}}+2.3    = 6.02 seconds

A) H(t) = -7.5(t - 2.2)² + 112

maximum height (k) = 112 feet

distance traveled (x) = \sqrt{\dfrac{-112}{-7.5}}+2.2    = 6.06 seconds

B) H(t) = -6.9(t - 2.3)² + 112

maximum height (k) = 112 feet

distance traveled (x) = \sqrt{\dfrac{-112}{-6.9}}+2.3    = 6.33 seconds

C) H(t) = -6.9(t - 2.4)² + 95

maximum height (k) = 95 feet

This has a lower height than the given equation.

D) H(t) = -7.5(t - 2.3)² + 95

maximum height (k) = 95 feet

This has a lower height than the given equation.

Both options A and B travel higher and stay in the air longer than last year's winner, however option B stays in the air longer than option A.
