Which point is an intercept of the quadratic function
x) = (x-8)(x+9)
(0,8)
(0,-8)
(9,0)
(-9,0)
Answer:
Step-by-step explanation:
x intercepts are points on the graph when the graph crosses the x axis, that is, when y is 0. if y is a sum of a product, then it is 0 when one of its factors is 0.
it's factors are:
x-8 (so x is 8)
x+9 ( I assume that the missing sign is a plus) (x would be -9)
this means that it's x-intercept is (-9,0) - only this option includes the intercept.
The other intercept is (8,0) BRAINLIEST LOL :)

Step-by-step explanation:
Assume L is length and W is width.
2 times length = 2L
plus = "+"
2 times width = 2W
is = "="
twenty-six = 26

Tina has 13 cups of water to divide evenly among 7 plants. which of the following best approximates the number of cups of water that each plant will get ?
1/2, 1, 1 1/2, 2, 2 1/2
Answer:
Option d, 2 cups.
Step-by-step explanation:
Tina has the number of cups of water = 13
She has to divide evenly among the number of plants = 7
The number of cups of water that each plant will get
= [tex]\frac{13}{7}[/tex] cups
= [tex]1\frac{6}{7}[/tex] cups
= 1.857 ≈ 1.9 cups
among the given 4 option, best approximates the number of cups would be 2 cups.
Option d, 2 cups.

Joshua and Caleb work at a furniture store. Joshua is paid $175 per week plus 5% of his total sales in dollars, x, which can be represented by g(x)=175+0.05x. Caleb is paid $532 per week plus 2% of his total sales in dollars, xx, which can be represented by f(x)=532+0.02x. Determine the value of x, in dollars, that will make their weekly pay the same.
Answer: x = $11,900
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
Joshua’s earnings: g(x)=175+0.05x
Caleb's earnings: f(x)=532+0.02x.
So, if both earnings are equal:
g(x) =f (x)
175+0.05x =532+0.02x
Solving for x:
0.05x-0.02x = 532-175
0.03x= 357
x = 357 /0.03
x = $11,900

Which transformations are rigid transformations? Check all that apply.
dilation
reflection
rotation
stretch
translation
Answer:
Reflection, rotation and translation
Step-by-step explanation:
By definition, a rigid transformation is a transformation that preserves length.
Dilation and stretch change the measure of the figure, and then, they are not rigid transformations.
On the other hand, reflection, rotation and translation don't change the measure of the figure, only change its position and orientation, so, they are rigid transformations.
Reflection, translation, dilation are rigid transformations.
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, translation and dilation.
Rigid transformations is a transformation that preserves the shape and size of the figure. Types of rigid transformation are reflection, translation, dilation.

A grapefruit is 8% heavier than an orange, and an apple is 10% lighter than the orange.
Answer:
The grapefruit is 20% heavier than the apple
Step-by-step explanation:
Say the orange's weight is o.
Grapefruit = 1.08o
Apple = 0.9o
So to find the percentage the grapefruit is bigger, you have to first do 1.08 - 0.9 = 0.18
0.18 / 0.9 = 0.2
0.2 = 20%
Answer:
i'm pretty sure the grapefruit is 20% more

Pls help me with this question
Answer:
6 years and 15 years of age
Step-by-step explanation:
Given the ratio of their ages is 2 : 5 = 2x : 5x ( x is a multiplier )
Then in 9 years their ages are 2x + 9 and 5x + 9 in the ratio 5 : 8
By proportion
[tex]\frac{2x+9}{5x+9}[/tex] = [tex]\frac{5}{8}[/tex] ( cross- multiply )
5(5x + 9) = 8(2x + 9) ← distribute parenthesis on both sides
25x + 45 = 16x + 72 ( subtract 16x from both sides )
9x + 45 = 72 ( subtract 45 from both sides )
9x = 27 ( divide both sides by 9 )
x = 3
Thus
Rohit's age = 2x = 2( 3) = 6
James' age = 5x = 5(3) = 15
6 : 15 = 2 : 5
