For the function j(x)=-4/5x+7, the value of x that will make j(x) equal to -5 is 15.
Explanation:The question asks us to find the value of x for the function j(x)=-4/5x+7 when j(x) is -5. To solve this problem, we can simply substitute j(x) with -5 in the function equation and solve for x.
So, -5 = -4/5x + 7. We can then rearrange this equation to leave x on one side, leading to -4/5x = -5 - 7, which simplifies to -4/5x = -12. To find x, we then divide both sides by -4/5, resulting in x = -12 / (-4/5) = 15.
Therefore, the solution is x = 15, and the given function j(x) will equal -5 when x is 15.

Convert the fraction into a decimal: 35/10 =
Answer: 3.5
Step-by-step explanation: In order to write [tex]\frac{35}{10}[/tex] as a decimal, we need to find a fraction that is equivalent to [tex]\frac{35}{10}[/tex] with a 100 in the denominator. Notice that if we multiply the numerator and denominator of [tex]\frac{35}{10}[/tex] by 10, we get the equivalent fraction [tex]\frac{350}{100}[/tex] which we can now write as a decimal. Remember that the hundredths place is two places to the right of the decimal point. Therefore, we can write [texfrac{350}{100}[/tex] as 3.5.

the triangles shown below must be congruent. right awnsers only please.
Answer: false
Step-by-step explanation:
Answer:
False
Step-by-step explanation:
Properties of congruent triangle :
SSS -"side, side, side" and means that we have two triangles with all three sides equal.
ASA- "angle, side, angle" and means that we have two triangles where we know two angles and the included side are equal.
SAS -"side, angle, side" and means that we have two triangles where we know two sides and the included angle are equal.
AAS -"angle, angle, side" and means that we have two triangles where we know two angles and the non-included side are equal.
Since the given triangles does not satisfy any property
So, the given triangles are not congruent.
So, Option B is true
Hence False

Jimmy ran m miles in t minutes. What was his speed?
To find Jimmy's speed, we use the formula speed = distance/time and represent his speed as m miles / t minutes.
Explanation:To find Jimmy's speed, we need to use the formula speed = distance/time. In this case, Jimmy ran m miles in t minutes. So, his speed can be represented as:
Speed = m miles / t minutes

Hours worked 2 4 5 8
Amount paid ($) 25 50 62.50 100
Which equation could represent Relationship A?
Hours worked is represented by x and Amount paid is represented by y.
Select each correct answer.
y = 13x
y = 11.5x
y = 12.75x
y = 12.25x
Answer:
y = 13x ; and y = 12.75x
Explanation:
The rate of change is another name for slope. To find the slope of Relationship B, we use the formula
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Using the first two points, we have
m = (50-25)/(4-2) = 25/2 = 12.5
This means that anything with a rate of change greater than 12.5 works in this problem.
The equations listed for Relationship A are in slope-intercept form, y=mx+b, where m is the slope and b is the y-intercept (in all of these, b = 0).
In the first equation, m = 13; in the second equation, m = 11.5; in the third equation, m = 12.75; and in the fourth equation, m = 12.25. The only ones with higher slopes than Relationship B are the first and the third one.
Beau's recipe for granola bars calls for 3 1/2 cups of oatmeal. He only has a 1/6 cup scoop. How many scoops of oatmeal will he need to complete the recipe?
There will be [tex]\boxed{\bf 21}[/tex] scoops of oatmeal to complete the recipe.
Further explanation:
Given that Beau’s recipe of granola bars contains [tex]3\frac{1}{2}[/tex] cups of oatmeal.
Beau’s has only [tex]\frac{1}{6}[/tex] cup scoop.
Our aim is to find the number of scoops of oatmeal Beau’s needed to complete the recipe for granola bars.
Total cups of oatmeal are [tex]3\frac{1}{2}[/tex].
First we have to convert the total cups of oat meal to proper fraction.
[tex]\begin{aligned}\text{Cups of oatmeal for the recipe}&=\dfrac{(3\cdot 2)+1}{2}\\&=\dfrac{6+1}{2}\\&=\dfrac{7}{2}\end{aligned}[/tex]
There is only [tex]\frac{1}{6}[/tex] cup scoop.
Since there are [tex]\frac{7}{2}[/tex] cups of oatmeal and [tex]\frac{1}{6}[/tex] cup scoop, therefore, number of scoops required to complete the meal are calculated as follows:
[tex]\begin{aligned}\text{Number of scoops required}&=\dfrac{\frac{7}{2}}{\frac{1}{6}}\\&=\dfrac{7}{2}\cdot 6\\&=7\cdot 3\\&=21\end{aligned}[/tex]
The total number of scoops is obtained in whole number; therefore, this is our final answer.
Therefore, [tex]\boxed{\bf 21}[/tex] scoops of oatmeal are needed by Beau’s to complete the recipe of granola bars.

The Beau has [tex]\dfrac{1}{6}{\text{ scoop}}.[/tex]
The number of scoops that are required to complete the recipe can be obtained as follows,
[tex]\begin{aligned}N&=\dfrac{{{\text{total cups of oatmeal}}}}{{{\text{the fraction of scoop Beau has}}}}\\&=\dfrac{{\dfrac{7}{2}}}{{\dfrac{1}{6}}}\\&= \frac{7}{2} \times 6\\&=\dfrac{{42}}{2}\\&= 21\\\end{aligned}[/tex]
The number of scoops required to complete the oatmeal is [tex]21{\text{ scoops}}.[/tex]
Therefore, [tex]\boxed{21}[/tex] number of scoops of oatmeal will he need to complete the recipe.

are the given lines parallel y=-5 y=3 ? how do you know? ASAP TY
The lines y = -5 and y = 3 are parallel because they are both horizontal lines with a slope of 0. This is the same case with lines Y2 and Y3 from the reference provided; they are parallel because they share the same slope.
Explanation:The lines y = -5 and y = 3 are indeed parallel lines. This is because they are both horizontal lines, which means their slopes are both 0. In mathematics, two lines are parallel if and only if their slopes are equal. In the case of these two lines, since they do not have a variable component (x), they are straight horizontal lines, meaning their slopes are equal and thus, they are parallel.
To illustrate this, contrast it with the given lines in the reference; line Y2 = -173.5+ 4.83x − 2(16.4), and line Y3 = -173.5+ 4.83x + 2(16.4), whereby y = -173.5+ 4.83x is the line of best fit. Y2 and Y3 have the same slope, which shows these lines are also parallel as they share the same inclination and distance apart at all points.
