Which equation, when graphed, has x-intercepts at (2, 0) and (4, 0) and a y-intercept of (0, –16)?

wlad13 [49]

The zeros are 2 and 4, so obviously either A or C, (eliminate B and D which have zeros of -2 and -4.)
the y intercept is -16. Plug x=0 in A and C to see which equation produce a result -16. C is correct.

What I the slope of a line that is perpendicular to the line 2y-3x=8

Zolol [24]

<u>ANSWER</u>

$- \frac{2}{3}$

<u>EXPLANATION</u>

The given given equation is

$2y - 3x = 8$

We need to rewrite this equation in the slope-intercept form:

$y = mx + b$

We add 3x to both sides.

$2y - 3x + 3x=8 + 3x$

$\implies \: 2y = 3x + 8$

We divide through by 2 to get,

$y = \frac{3}{2}x + 4$

The slope of this line is

$m = \frac{3}{2}$

Let the slope of the line perpendicular to this line be 'n' .

Then the product of the slopes of two perpendicular lines is always negative 1.

$m \times n = - 1$

$\implies \: \frac{3}{2} n = - 1$

$\implies \: \frac{2}{3} \times \frac{3}{2}n = - 1 \times \frac{2}{3}$

$n = - \frac{2}{3}$

Therefore the slope of the new line is

$- \frac{2}{3}$

Answer:

WX = 8 mm

Step-by-step explanation:

To be able to solve for WX, we need to first find the size of angle $\angle z$ .

We use the law of sines in the blue triangle to do such:

$\frac{sin(z)}{11} =\frac{sin(133)}{20} \\sin(z)=\frac{11\,sin(133)}{20} \\sin(z)=0.4022$

Now we can use this value in the larger right angle triangle where WX is the opposite side to angle $\angle z$ , and the 20 mm side is the hypotenuse:

$sin(z)=\frac{opposite}{hypotenuse} \\sin(z)=\frac{WX}{20}\\0.4022=\frac{WX}{20}\\WX=20\,(0.4022)\\WX=8.044\,\,mm$

which rounded to the nearest integer gives

WX = 8 mm

The store is selling lemons at $0.39 each. Each lemon yields about 2 tablespoons of juice. How much will it cost to buy enough l

I am Lyosha [343]

Answer: 6.24 tablespoons

Explanation: okay so if $.39 is 2 tablespoons, then you can multiply that by 8 because there are 8 tablespoons in half a cup. After you multiply that just multiply it by 2 because they are trying to make two pies. And that’s how you your answer.

Eva8 [605]

5 cups & 4 teaspoons
? cups & 6 teaspoons

2.5 cups is half of 5
2 is half of 4

you increased the recipe by 1/2

so for 6 teaspoons you will need 7.5 or 7 1/2 cups of flour b/c 5 + 2.5 = 7.5
