Answer:
d=√((x_2-x_1)²+(y_2-y_1)²)
d=√((2-(-4))²+(1-(-3))²)
d=√(6²+4²)
d=√36+16
d=√52
d=7.21110255...
d=7.2
Step-by-step explanation:
d=7.2
The distance between the points on the coordinate plane is 7.2 units.
What is coordinate geometry?Coordinate geometry is the study of geometry using the coordinate points. It provides a link between geometry and algebra through line graphs and curves.
For the given situation,
The points are (x1, y1) be (–4, –3) and (x2, y2) be (2, 1)
The formula for the distance between points,
[tex]d=\sqrt{(x2-x1)^{2}+(y2-y1)^{2} }[/tex]
On substituting the above points,
⇒ [tex]d=\sqrt{(2-(-4))^{2}+(1-(-3))^{2} }[/tex]
⇒ [tex]d=\sqrt{6^{2}+4^{2} }[/tex]
⇒ [tex]d=\sqrt{52}[/tex]
⇒ [tex]d=7.211[/tex] ≈ [tex]7.2[/tex]
Hence we can conclude that the distance between the points on the coordinate plane is 7.2 units.

What is the value of the expression below when a = -2, b = 3, C = -5
[a– 2ac + 56]
Answer:
34
Step-by-step explanation:
plug the coefficients in the equation, so
-2-2(-2)(-5)+56
Distribute the -2(-2)(-5), so it equals -20
so the equation is -2-20+56
add -20+56, so -2+36
-2+36=34

Walter and Denise ordered a dessert to share at a restaurant. If Denise ate 1 8 of the dessert and Walter ate 4 5 of the dessert, what fraction of the dessert was left over?
Answer:
3/40
Step-by-step explanation:
Walter and Denise ordered a dessert to share at a restaurant. If Denise ate 1/8 of the dessert and Walter ate 4/5 of the dessert, what fraction of the dessert was left over?
Let the total dessert be represented as = 1
The fraction of the dessert left over =
1 - (4/5 + 1/8)
Lowest Common Denominator = 40
1 - (4 × 8 + 1 × 5/40)
1 - (32 + 5/40)
1 - 37/40
Lowest Common Denominator = 40
40 × 1 - 37 × 1/40
40 - 37/40
= 3/40
Therefore, the fraction of dessert that is left over = 3/40
